Okay artists, please help!
I'm working on the TDE user guide. I need some image conversion help.
I want to convert some 24-bit PNG images to "locolor." What does
"locolor" mean? These are not icons but full images, in case that makes a
difference. Is there a definition somewhere of "locolor"?
How do I convert/save a 24-bit image as "locolor"?
Of all of the various TDE image viewers, how do I view an image's properties to learn
about the color depth, etc.? I have tried several (kolourpaint, krita, showfoto,
gwenview). I am missing the big picture altogether, probably because I don't know the
terminology.
Thanks!
Darrell

Ya got me there. Dunno (yet) what "locolor" means. First guess is it's
_less_ than 24-bit color.
How do I convert/save a 24-bit image as
"locolor"?
ImageMagick ? read on:

`display` from ImageMagick:
$ display whatever.png
<right-click> on the image, and select "Image Info" from the dropdown.
`convert` from ImageMagick may be what you want to achieve "locolor".

How do I do those things with Trinity apps? Considering all the Trinity graphics apps I
would have thought that learning image information should be trivial. Thus far the only
stat I have learned is size. Nothing about color depth, etc.
A quick check shows that ImageMagick provides some of that information, but let's get
back to Trinity. :)
Considering that throughout Linux-dom icons are packaged as hicolor and locolor, I would
have thought that within a link or two I would discover the criteria or definition of
those terms. I'm still looking....

Hi Darrell,
I believe that "locolor" images (like some of the old icons) have a colour-depth
of 8 bits. You can convert images to 8 bits with Showfoto. Just select color >
depth > 8 bits.
I hope this helps.

Correct. locolour is 8-bit or (256 colour). In konqueror just hover over
the image and look for the image bpp (probably 256 for tranparencies in
icons). I believe kfile plugins handle this. You can open the image in
kolourpaint and choose 'save as' .... then select 256 colours from the drop
down. You will be warned that saving in locolor (8-bit) will may compromise
transparency.
