HTML Text and Images

[Ray Horsley]

Many thanks to Andre Garzia for help on this.  I'm still faced with some
[possibly new] issues regarding setting the htmlText of a fld.  What I need
is the height and width of images inside the htmlText.  Ideally I'd like to
manipulate height and width.  I'm not downloading any images as files and
I'm not using the binFile format so I don't believe they're residing
anywhere on my local disk.

Here's a typical span tag as an example:

<span><img
src="http://linkit.com/Schools/ETS%20Items/ETS%20Item%20Bank/ETS10Q1/01%20Fu
ll%20Bank/04%20ELA%20QTI%20with%20GUIDs/Grade%20KLanguage%20Arts-95/images/3
8228.jpg"</span>

Set the htmlText of any field to this string and you get a pretty little
bird, but how tall and how wide is that bird?

Thanks,

Ray Horsley

Ray,

You need to set it to some place where the compound assembly of the
defaultfolder + your imagesource value actually resolves to a real file.

So if you have the following imagesource set:

ETS Items/ETS Item Bank/ETS10Q1/01 Full Bank/06 Math QTI 0with GUIDs and
96dpi PNG/Grade 06Math-49/images/mml2504101.png

And that "ETS Items" is located at "~/Desktop/Rays App/" so that the actuall
file path is:

~/Desktop/Rays App/ETS Items/ETS Item Bank/ETS10Q1/01 Full Bank/06 Math QTI
0with GUIDs and 96dpi PNG/Grade 06Math-49/images/mml2504101.png

Then you just need to set the defaultfolder to "~/Desktop/Rays App/"

Image source has three possible resolutions:

(1) The image is inside revolution since imagesource value is an ID or image
name. Just figure out what image is and use it
(2) The image is a remote resource since we're given an fully qualified URL.
Load it from the server
(3) Image is a file on disk, see if it is a full path or relative path to
our defaultfolder and solve it.

I actually think that cases (2) and (3) are actually the same. I don't know
if you can simply pass a path without the binfile protocol in it.

Try changing your source to something like:

binfile:ETS Items/ETS Item Bank/ETS10Q1/01 Full Bank/06 Math QTI 0with GUIDs
and 96dpi PNG/Grade 06Math-49/images/mml2504101.png

Remember the relative folder, if possible, always use full paths by figuring
out the path before assembling the HTMLText chunk and replacing the
variables.
