Hi
Has anyone got a handler that works out the image type from the text of the
image. I want to save the text of an image but I want to do so with the correct
extension. I don't want to use the export command because of the risk of some
quality loss from the image.
This is for the VCS stuff
OK.. came up with the following based on a StackOverflow answer on doing this
in C. Anyone have anything better?:
function imageDataExtension pData
if char 1 to 4 of pData is GIF8 then
return gif
else if byteToNum(char 1 of pData) is 255 and byteToNum(char 2 of pData) is
216 then
Hi Monte:
You can probably use the paintCompression property to check the image
type. It might also help to know that PNG is essentially lossless -- you
shouldn't lose any image data using this format. You may find that
dealing with the gamma of PNG images is something of a black art and can
Ah... the paintCompression might be sufficient to use as an extension. It's not
perfect but it will probably do.
Basically if someone imported a JPG I didn't think it would be suitable for the
VCS to export/import as png. If you say it would be ok then I'll run with that.
What I'm doing is
It turns out the paintCompression is yet another property not in the properties
array (YAPNITPA)...

Not sure about your setup, but I imagine you could store binary image data
so you don't have to mess with image format all. The one complication is
if you allow folks to scale an image in whatever you're doing. You'll
need to save the reformatted image data, so recompressing JPEG shouldn't
be an

Monte,
If you are using the properties of an object stored in an array for rebuilding
a stack in your VCS, you probably should be aware of
Thanks Paul
For readability of the properties file I have moved the colors and patterns to
their named individual counterparts rather than the list you get in the
properties array. Otherwise in a text diff it's unclear exactly which property
changed. So I don't think my code will have this
