mouli parsmint

Posted by odd lie On 25. oktober 2014

Fantastisk gamle kjøkkenet jeksel eller chopper med gul plast håndtaket fra den berømte Mouli familien.

Opprinnelig brukt til å hogge urter som persille eller mynte – sette noen friske urter i toppen, vri håndtaket og du har klar til bruk hakket urter. Perfekt!

Dette Rotary chopper, som er i perfekt stand, kan lett demonteres for rengjøring som det åpner opp med en fangst på undersiden av håndtaket. Håndtaket kan også være plassert på enten høyre eller venstre slik at det er egnet for både høyre- og venstrehendte .

Håndtaket er merket "création" MOULIN-LEGUMES "(grønnsaks mill). Fronten er merket Mouli PARSMINT og sidene lese" en "Mouli 'PRODUCT" og patentsøkt. Mouli Merket ble grunnlagt i 1950 og er kjent for sin franske kjøkkenutstyr.

Denne hendige kjøkken verktøyet måler ca 18cm (7 ") lang sammenlagt og er 7,5 cm (3 '') på sitt bredeste delen. Håndtaket, hjul og bladene beveger seg jevnt, og det ser ut til å være i god stand.

Det er i veldig god vintage stand, uten rust, men noen få anløpe flekker her og der. Den gule bakelitt håndtak har en liten chip, men er fortsatt robust. I tillegg til å være funksjonelle, ville dette Mouli gjøre narr kjøkken innredning og være et flott element å legge til enhver samling.

// how to use template tags

				public function section_4() { ?>
			

<p>

				The Image Metadata Cruncher plugin uses template tags enclosed in curly brackets
			

to place metadata into your predefined templates.

You can use multiple template tags inside one template.

The tags are case insensitive so

<code>{ EXIF:ImageDescription }</code> is the same as

<code>{ exif:imagedescription }</code> or

<code>{ EXIF:IMAGEDESCRIPTION }</code>.

Only tags with valid syntax will be processed by the plugin.

				Faulty tags will be ignored and printed out in the <em>Upload New Media</em> form as they are.
			

				Valid template tags get highlighted as you type, so you can immediately see whether they are valid or not.
			

</p>

<br />

<h2>Simplest template tag</h2>

<p>

The simplest tag consist of a metadata keyword inside curly brackets.

The keyword itself consist of prefix defining the metadata category e.g.

<code>IPTC</code>, <code>EXIF</code> a colon

and the actual metadata identifier

<code>Make</code>:

</p>

<code>

{ EXIF:Make }

</code>

<p>

If for instance you only need to retrieve the information about the camera make

from the image EXIF metadata you can use it like this:

</p>

{ EXIF:Make }

</div>

<p>

				If the image contains the requested metadata the tag will be replaced with the found value and
			

if the image was taken with a Canon camera, the text in the

<em>Upload New Media</em> form would be:

</p>

Canon

</div>

<p>

				If the image doesn't contain such information the tag will return an empty string:
			

</p>

<br />

<h2>Template tag with fallback keywords</h2>

<p>

				It can happen that the image doesn't contain the metadata specified in the template tag
			

but contains another, similar one in some other metadata field.

				In such cases you can specify a fallback keyword inside the tag after the first one
			

delimited by the <code>|</code> pipe sign.

</p>

<code>

{ IPTC:Caption | EXIF:ImageDescription }

</code>

<p>

				If for instance you want to retrieve the image's IPTC caption and in case it is not available
			

try to get the EXIF image description you can use a tag like this:

</p>

{ IPTC:Caption | EXIF:ImageDescription }

</div>

<p>

If the image contains the IPTC caption it will return it:

</p>

Sample IPTC caption.

</div>

<p>

				If not, it tries to retrieve the value specified in the next keyword after the pipe, which is
			

				<code>EXIF:ImageDescription</code>. If the image contains it, the tag will be replaced with it.
			

</p>

Sample EXIF image description.

</div>

<p>

				Again, if the image doesn't contain any of the requested metadata, it will return an empty string:
			

</p>

<p>

You can chain as many fallback keywords as you want.

The tag will be replaced with the first found value in specified order.

</p>

<code>

{ IPTC:Headline | IPTC:ObjectName | EXIF:ImageDescription | EXIF:ModifyDate }

</code>

<br />

<h2>Available Metadata</h2>

<p>

The first part of a keyword (before the colon) specifies the metadata group,

				the second part (after the colon) specifies a particular metadata within the group.
			

There are three main groups of metadata:

<code>EXIF</code>,

<code>IPTC</code> and

<code>ALL</code>.

</p>

<p>

The <code>EXIF</code> and <code>IPTC</code> groups are self explanatory.

Check the

				<a href="?page=image_metadata_cruncher-options&tab=metadata">Available Metadata</a> 
			

section to get the list of available suffixes.

</p>

<p>

The <code>ALL</code> group is special. Its main purpose is debugging.

				It returns all metadata found in the uploaded image formatted according to the keyword suffix,
			

which can be <code>php</code>, <code>json</code> and <code>jsonpp</code>.

</p>

<p>

Here is a truncated example of

tag in action.

</p>

{ ALL:php }

</div>

<p>

It returns all metadata found in the image formatted as nested PHP arrays.

<h2>Accessing Nested Metadata</h2>

<p>

As you can see on the example above some of the metadata like

<code>EXIF:COMPUTED</code> or

are in the form of an array.

You can request such metadata directly:

</p>

{ EXIF:COMPUTED }

</div>

<p>

If found the value will be returned as a comma separated list.

</p>

width="589" height="632", 632, 589, 1, 0, f/2.8, 4294967296.00m, 2, image/jpeg

</div>

<p>

Or you can acces the items of the array by specifiing the desired index

after a <code>></code> greater than sign:

</p>

{ EXIF:COMPUTED>FocusDistance }

</div>

<p>

If found the value will be returned directly.

</p>

4294967296.00m

</div>

<p>

The path can be nested arbitrarily deep. You can even use it with the

<code>ALL</code> category like this:

</p>

{ ALL:json>EXIF>COMPUTED }

</div>

<p>

If found the value will be returned as a JSON array.

</p>

				{"html":"width="589" height="632"","height":632,"width":589,"iscolor":1,"byteordermotorola":0,"aperturefnumber":"f/2.8","focusdistance":"4294967296.00m","thumbnail.filetype":2,"thumbnail.mimetype":"image/jpeg"}
			

</div>

<br />

<h2>Other Tag Options</h2>

<p>

Tags are replaced by empty string if no metadata found.

This can sometimes lead to undesired results:

</p>

The picture was taken with { EXIF:Make } camera.

</div>

<p>

If found, there's no problem.

</p>

The picture was taken with Canon camera.

</div>

<p>

If not found, the result is a pointless sentence with double whitespace between

the words <em>with</em> and <em>camera</em>.

</p>

The picture was taken with  camera.

</div>

<br />

<h3>The Default Option</h3>

<p>

We can avoid that by using the

<strong>default</strong> option in the form <code>% "not found text"</code>.

The previous example would then look like this:

</p>

The picture was taken with { EXIF:Make % "unknown" } camera.

</div>

<p>

If found, the tag would be replaced by the found value.

</p>

The picture was taken with Canon camera.

</div>

<p>

If not found, the default text will be used.

</p>

The picture was taken with unknown camera.

</div>

<br />

<h3>The Success Option</h3>

<p>

The <strong>success</strong> option in the form <code>@ "success $ text"</code>

				together with the default option allow you to have greater controll over the resulting text.
			

				The <code>$</code> dollar sign has a special meaning and will be replaced by the found value.
			

Here is an example:

</p>

				{ EXIF:Model @ "The picture was taken with $." % "Camera info is not available!" }
			

</div>

<p>

				If found, the tag would be replaced by the string specified in the success option,
			

with the <code>$</code> dollar sign replaced by the found value.

</p>

The picture was taken with Canon EOS 7D.

</div>

<p>

If not found, the default text will be used.

</p>

Camera info is not available!

</div>

<br />

<h3>The Delimiter Option</h3>

<p>

				The <strong>delimiter</strong> option in the form <code># "delimiter text"</code>
			

allows you to replace the default delimiter

<code>, </code> which separates the values returned by array metadata.

</p>

{ EXIF:LensInfo # " >>> " }

</div>

<p>

				If the found metadata is an array, the delimiter string will be used to separate its values.
			

</p>

70/1 >>> 200/1 >>> 0/0 >>> 0/0

</div>

<br />

<h3>Special Characters in Options</h3>

<p>

Except for the <strong>success</strong> option there is only one

special character <code>"</code> the doublequote which must be escaped

by a backslash <code>\"</code> if you want to use it inside the string.

In the <strong>success</strong> option also the <code>$</code>

dollar sign must be escaped <code>\$</code> if you don't want it to be replaced

by the found value.

</p>

<br />

<h3>Printing Out Valid Tags</h3>

<p>

				If for some strange reason you want to print out a valid tag instead of being processed
			

use escaped curly brackets <code>\{\}</code>

</p>

{ EXIF:Make }, \{ EXIF:Make \}

</div>

<p>

The first tag will be processed, the second ignored and printed out.

</p>

Canon, { EXIF:Make }

</div>

<br />

<h2>Using it All Together</h2>

<p>

You can use all the tag options together, but they must appear in the tag

in a particular order.

You can skip any of the option but you need to preserve the order.

</p>

<ol>

<li>

				Metadata keywords <code>IPTC:Headline | IPTC:ObjectName | EXIF:ImageDescription</code>
			

</li>

<li>

Success option <code>@ "success text"</code>

</li>

<li>

Default option <code>@ "default text"</code>

</li>

<li>

Delimiter option <code>@ "delimiter text"</code>

</li>

</ol>

<p>

				The whitespace inside tags has no special meaning and you can completely skip it.
			

</p>

<p>

Here are some examples of valid tags:

</p>

{ EXIF:LensInfo>2 } array index 2

</div>

<br />

{ EXIF:LensInfo | EXIF:LensModel | EXIF:LensMake } fallback keywords

</div>

<br />

				{ EXIF:SceneCaptureType | EXIF:ExposureMode | IPTC:TimeSent @ "Info: $" % "No info found!" # " \ " } all together
			

</div>

<br />

				{ EXIF:LensInfo | EXIF:LensModel % "No lens info found!" # " >>> " } default and delimiter
			

</div>

<br />

{ EXIF:LensInfo @ "Lens info: $" # " >>> " } success and delimiter

</div>

<br />

{ EXIF:Make @ "Camera is \"$\"" } success with escaped quotes

</div>

<br />

{ IPTC:ObjectName } is the same as { IPTC:2#005 }

</div>

<br />

{ EXIF:ExposureIndex } is the same as { EXIF:0xa215 }

</div>

<br />

{ foo:bar % "I bet this text gets printed!" } insane keywords are still valid

</div>

<br />

<p>

And here some invalid ones:

</p>

{ EXIF:LensInfo> } trailing >

</div>

<br />

{ EXIF:LensInfo | EXIF:LensModel | EXIF:LensMake | } trailing |

</div>

<br />

{ EXIF:Make @ "Camera is "$"" } unescaped quotes in option string

</div>

<br />

{ EXIF:LensInfo # " >>> " % "No lens info found!" } options in bad order

</div>

<br />

{ EXIF:LensInfo # " >>> " @ "Lens info: $" } options in bad order

</div>

<br />

{ EXIF:LensMake % "No lens info found!" @ "Lens info: $" } options in bad order

</div>

<br />

	// how to use template tags
	public function section_4() { ?>
	<p>
	The Image Metadata Cruncher plugin uses template tags enclosed in curly brackets
	<code>{}</code>
	to place metadata into your predefined templates.
	You can use multiple template tags inside one template.
	The tags are case insensitive so
	<code>{ EXIF:ImageDescription }</code> is the same as
	<code>{ exif:imagedescription }</code> or
	<code>{ EXIF:IMAGEDESCRIPTION }</code>.
	Only tags with valid syntax will be processed by the plugin.
	Faulty tags will be ignored and printed out in the <em>Upload New Media</em> form as they are.
	Valid template tags get highlighted as you type, so you can immediately see whether they are valid or not.
	</p>
	<br />

	<h2>Simplest template tag</h2>
	<p>
	The simplest tag consist of a metadata keyword inside curly brackets.
	The keyword itself consist of prefix defining the metadata category e.g.
	<code>IPTC</code>, <code>EXIF</code> a colon
	<code>:</code>
	and the actual metadata identifier
	<code>Make</code>:
	</p>
	<code>
	{ EXIF:Make }
	</code>
	<p>
	If for instance you only need to retrieve the information about the camera make
	from the image EXIF metadata you can use it like this:
	</p>
	<div class="ce highlighted">
	{ EXIF:Make }
	</div>
	<p>
	If the image contains the requested metadata the tag will be replaced with the found value and
	if the image was taken with a Canon camera, the text in the
	<em>Upload New Media</em> form would be:
	</p>
	<div class="example ok">
	Canon
	</div>
	<p>
	If the image doesn't contain such information the tag will return an empty string:
	</p>
	<div class="example err"></div>
	<br />

	<h2>Template tag with fallback keywords</h2>
	<p>
	It can happen that the image doesn't contain the metadata specified in the template tag
	but contains another, similar one in some other metadata field.
	In such cases you can specify a fallback keyword inside the tag after the first one
	delimited by the <code>\|</code> pipe sign.
	</p>
	<code>
	{ IPTC:Caption \| EXIF:ImageDescription }
	</code>
	<p>
	If for instance you want to retrieve the image's IPTC caption and in case it is not available
	try to get the EXIF image description you can use a tag like this:
	</p>
	<div class="ce highlighted">
	{ IPTC:Caption \| EXIF:ImageDescription }
	</div>
	<p>
	If the image contains the IPTC caption it will return it:
	</p>
	<div class="example ok">
	Sample IPTC caption.
	</div>
	<p>
	If not, it tries to retrieve the value specified in the next keyword after the pipe, which is
	<code>EXIF:ImageDescription</code>. If the image contains it, the tag will be replaced with it.
	</p>
	<div class="example ok">
	Sample EXIF image description.
	</div>
	<p>
	Again, if the image doesn't contain any of the requested metadata, it will return an empty string:
	</p>
	<div class="example err"></div>
	<p>
	You can chain as many fallback keywords as you want.
	The tag will be replaced with the first found value in specified order.
	</p>
	<code>
	{ IPTC:Headline \| IPTC:ObjectName \| EXIF:ImageDescription \| EXIF:ModifyDate }
	</code>
	<br />
	<br />

	<h2>Available Metadata</h2>
	<p>
	The first part of a keyword (before the colon) specifies the metadata group,
	the second part (after the colon) specifies a particular metadata within the group.
	There are three main groups of metadata:
	<code>EXIF</code>,
	<code>IPTC</code> and
	<code>ALL</code>.
	</p>
	<p>
	The <code>EXIF</code> and <code>IPTC</code> groups are self explanatory.
	Check the
	<a href="?page=image_metadata_cruncher-options&tab=metadata">Available Metadata</a>
	section to get the list of available suffixes.
	</p>
	<p>
	The <code>ALL</code> group is special. Its main purpose is debugging.
	It returns all metadata found in the uploaded image formatted according to the keyword suffix,
	which can be <code>php</code>, <code>json</code> and <code>jsonpp</code>.
	</p>
	<p>
	Here is a truncated example of
	<code>{ ALL:php }</code>
	tag in action.
	</p>
	<div class="ce highlighted" >
	{ ALL:php }
	</div>
	<p>
	It returns all metadata found in the image formatted as nested PHP arrays.
	</p>
	<div class="example ok"><pre style="overflow: hidden">Array
	(
	[Image] => Array
	(
	[0] => 589
	[1] => 632
	[2] => 2
	[3] => width="589" height="632"
	[bits] => 8
	[channels] => 3
	[mime] => image/jpeg
	)

	[IPTC] => Array
	(
	[1#005] => Destination
	[Destination] => Destination
	[1#000] => �
	[EnvelopeRecordVersion] => �
	[1#050] => ProductID
	[ProductID] => ProductID
	(…rest truncated for brevity…)
	)

	[EXIF] => Array
	(
	[FileName] => phpbNUtQp
	[FileDateTime] => 1352388440
	[FileSize] => 145110
	[FileType] => 2
	[MimeType] => image/jpeg
	[SectionsFound] => ANY_TAG, IFD0, THUMBNAIL, EXIF

	[Thumbnail.FileType] => 2
	[Thumbnail.MimeType] => image/jpeg
	)
	(…rest truncated for brevity…)
	)
	)</pre></div>


	<br />

	<h2>Accessing Nested Metadata</h2>
	<p>
	As you can see on the example above some of the metadata like
	<code>EXIF:COMPUTED</code> or
	<code>EXIF:0xA432</code>
	are in the form of an array.
	You can request such metadata directly:
	</p>
	<div class="ce highlighted" >
	{ EXIF:COMPUTED }
	</div>
	<p>
	If found the value will be returned as a comma separated list.
	</p>
	<div class="example ok">
	width="589" height="632", 632, 589, 1, 0, f/2.8, 4294967296.00m, 2, image/jpeg
	</div>
	<p>
	Or you can acces the items of the array by specifiing the desired index
	after a <code>></code> greater than sign:
	</p>
	<div class="ce highlighted" >
	{ EXIF:COMPUTED>FocusDistance }
	</div>
	<p>
	If found the value will be returned directly.
	</p>
	<div class="example ok">
	4294967296.00m
	</div>
	<p>
	The path can be nested arbitrarily deep. You can even use it with the
	<code>ALL</code> category like this:
	</p>
	<div class="ce highlighted" >
	{ ALL:json>EXIF>COMPUTED }
	</div>
	<p>
	If found the value will be returned as a JSON array.
	</p>
	<div class="example ok">
	{"html":"width="589" height="632"","height":632,"width":589,"iscolor":1,"byteordermotorola":0,"aperturefnumber":"f/2.8","focusdistance":"4294967296.00m","thumbnail.filetype":2,"thumbnail.mimetype":"image/jpeg"}
	</div>
	<br />

	<h2>Other Tag Options</h2>
	<p>
	Tags are replaced by empty string if no metadata found.
	This can sometimes lead to undesired results:
	</p>
	<div class="ce highlighted" >
	The picture was taken with { EXIF:Make } camera.
	</div>
	<p>
	If found, there's no problem.
	</p>
	<div class="example ok">
	The picture was taken with Canon camera.
	</div>
	<p>
	If not found, the result is a pointless sentence with double whitespace between
	the words <em>with</em> and <em>camera</em>.
	</p>
	<div class="example err">
	The picture was taken with  camera.
	</div>
	<br />

	<h3>The Default Option</h3>
	<p>
	We can avoid that by using the
	<strong>default</strong> option in the form <code>% "not found text"</code>.
	The previous example would then look like this:
	</p>
	<div class="ce highlighted" >
	The picture was taken with { EXIF:Make % "unknown" } camera.
	</div>
	<p>
	If found, the tag would be replaced by the found value.
	</p>
	<div class="example ok">
	The picture was taken with Canon camera.
	</div>
	<p>
	If not found, the default text will be used.
	</p>
	<div class="example err">
	The picture was taken with unknown camera.
	</div>
	<br />

	<h3>The Success Option</h3>
	<p>
	The <strong>success</strong> option in the form <code>@ "success $ text"</code>
	together with the default option allow you to have greater controll over the resulting text.
	The <code>$</code> dollar sign has a special meaning and will be replaced by the found value.
	Here is an example:
	</p>
	<div class="ce highlighted" >
	{ EXIF:Model @ "The picture was taken with $." % "Camera info is not available!" }
	</div>
	<p>
	If found, the tag would be replaced by the string specified in the success option,
	with the <code>$</code> dollar sign replaced by the found value.
	</p>
	<div class="example ok">
	The picture was taken with Canon EOS 7D.
	</div>
	<p>
	If not found, the default text will be used.
	</p>
	<div class="example err">
	Camera info is not available!
	</div>
	<br />

	<h3>The Delimiter Option</h3>
	<p>
	The <strong>delimiter</strong> option in the form <code># "delimiter text"</code>
	allows you to replace the default delimiter
	<code>, </code> which separates the values returned by array metadata.
	</p>
	<div class="ce highlighted" >
	{ EXIF:LensInfo # " >>> " }
	</div>
	<p>
	If the found metadata is an array, the delimiter string will be used to separate its values.
	</p>
	<div class="example ok">
	70/1 >>> 200/1 >>> 0/0 >>> 0/0
	</div>
	<br />

	<h3>Special Characters in Options</h3>
	<p>
	Except for the <strong>success</strong> option there is only one
	special character <code>"</code> the doublequote which must be escaped
	by a backslash <code>\"</code> if you want to use it inside the string.
	In the <strong>success</strong> option also the <code>$</code>
	dollar sign must be escaped <code>\$</code> if you don't want it to be replaced
	by the found value.
	</p>
	<br />

	<h3>Printing Out Valid Tags</h3>
	<p>
	If for some strange reason you want to print out a valid tag instead of being processed
	use escaped curly brackets <code>\{\}</code>
	</p>
	<div class="ce highlighted" >
	{ EXIF:Make }, \{ EXIF:Make \}
	</div>
	<p>
	The first tag will be processed, the second ignored and printed out.
	</p>
	<div class="example ok">
	Canon, { EXIF:Make }
	</div>
	<br />

	<h2>Using it All Together</h2>
	<p>
	You can use all the tag options together, but they must appear in the tag
	in a particular order.
	You can skip any of the option but you need to preserve the order.
	</p>
	<ol>
	<li>
	Metadata keywords <code>IPTC:Headline \| IPTC:ObjectName \| EXIF:ImageDescription</code>
	</li>
	<li>
	Success option <code>@ "success text"</code>
	</li>
	<li>
	Default option <code>@ "default text"</code>
	</li>
	<li>
	Delimiter option <code>@ "delimiter text"</code>
	</li>
	</ol>
	<p>
	The whitespace inside tags has no special meaning and you can completely skip it.
	</p>
	<p>
	Here are some examples of valid tags:
	</p>
	<div class="ce highlighted" >
	{ EXIF:LensInfo>2 } array index 2
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensInfo \| EXIF:LensModel \| EXIF:LensMake } fallback keywords
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:SceneCaptureType \| EXIF:ExposureMode \| IPTC:TimeSent @ "Info: $" % "No info found!" # " \ " } all together
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensInfo \| EXIF:LensModel % "No lens info found!" # " >>> " } default and delimiter
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensInfo @ "Lens info: $" # " >>> " } success and delimiter
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:Make @ "Camera is \"$\"" } success with escaped quotes
	</div>
	<br />
	<div class="ce highlighted" >
	{ IPTC:ObjectName } is the same as { IPTC:2#005 }
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:ExposureIndex } is the same as { EXIF:0xa215 }
	</div>
	<br />
	<div class="ce highlighted" >
	{ foo:bar % "I bet this text gets printed!" } insane keywords are still valid
	</div>
	<br />
	<p>
	And here some invalid ones:
	</p>
	<div class="ce highlighted" >
	{ EXIF:LensInfo> } trailing >
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensInfo \| EXIF:LensModel \| EXIF:LensMake \| } trailing \|
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:Make @ "Camera is "$"" } unescaped quotes in option string
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensInfo # " >>> " % "No lens info found!" } options in bad order
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensInfo # " >>> " @ "Lens info: $" } options in bad order
	</div>
	<br />
	<div class="ce highlighted" >
	{ EXIF:LensMake % "No lens info found!" @ "Lens info: $" } options in bad order
	</div>
	<br />
	<br />
