All,

I haven't solved the resizing of images in HTML pages, but here are my
thoughts. Hopefully they will offer some insight.

HTML IMG ELEMENT

Say an image in an HTML page needs to be localized. In this case, it is a
screen shot of the options dialog in Internet Explorer. The size of the
dialog varies slightly depending on the language.

	<img src="ieoptions2.gif" alt="Internet Security Options" width="305"
height="339" />

ATTEMPT USING JUST TRANS-UNIT

At first, I thought to create four <trans-unit> elements to store the four
attributes.

	<!-- src -->
	<trans-unit id="ieOptionsImg" restype="file">
		<source>ieoptions2.gif</source>
		<target></target>
	</trans-unit>
	<!-- alt -->
	<trans-unit id="ieOptionsAlt" datatype="plaintext">
		<source>Internet Security Options</source>
		<target></target>
	</trans-unit>
	<!-- width -->
	<trans-unit id="ieOptionsWidth" size-unit="pixel">
		<source>305</source>
		<target></target>
	</trans-unit>
	<!-- height -->
	<trans-unit id="ieOptionsHeight" size-unit="pixel">
		<source>339</source>
		<target></target>
	</trans-unit>

There are some problems with this first approach:

* It fails to group the width and height with the image.

* The URL in the src attribute can be changed, but does make use of the
<external-file> element. However, the 'restype' attribute has "file" as a
possible value, so I'm unsure which to use.

* The 'size-unit' attribute is defined to specify "the units of measure used
in the maxheight, minheight, maxwidth, and minwidth attributes", not the
units of the text in the <source> element.


ATTEMPT USING BIN-UNIT

Using <bin-unit>, it would appear as shown here.

<bin-unit id="ieOptions" mime-type="image/gif" reformat="yes">
	<bin-source>
		<external-file href="ieoptions2.gif" />
	</bin-source>
	<trans-unit id="ieOptionsSize" coord="0;0;305;339"
reformat="coord-cx;coord-cy">
		<source />
	</trans-unit>
	<trans-unit id="ieOptionsAlt" datatype="plaintext">
		<source>Internet Security Options</source>
		<target></target>
	</trans-unit>
</bin-unit>

Returning from the translator, it would appear as shown here.

<bin-unit id="ieOptions" mime-type="image/gif" reformat="yes">
	<bin-source>
		<external-file href="ieoptions2.gif" />
	</bin-source>
	<bin-target>
		<external-file href="ieoptions2fr.gif" />
	</bin-target>
	<trans-unit id="ieOptionsSize" coord="0;0;305;339"
reformat="coord-cx;coord-cy">
		<source />
		<target coord="0;0;309;374" />
	</trans-unit>
	<trans-unit id="ieOptionsAlt" datatype="plaintext">
		<source>Internet Security Options</source>
		<target>Options de securite Internet</target>
	</trans-unit>
</bin-unit>

This would produce the following HTML.

	<img src="ieoptions2fr.gif" alt="Options de securite Internet" width=309
height=374>


SUMMARY

To me, this approach is not intuitive. This is evident because I did not
originally consider using <bin-unit>. It does, however, seem reasonable to
me as long as documentation is provided with recommended practices and
sufficient examples are given. Without patterns to guide them, XLIFF
adoptors will be somewhat lost as to the best approach when transforming
their source to XLIFF.


QUESTIONS

* Should the <trans-unit> element for the 'alt' attribute be WITHIN the
<bin-unit> element or not?

* Are the 'coord' units always pixels or does the 'size-unit' also apply to
'coord' values?

* Yves, what does 'kenavo' mean?
