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!

Ya got me there. Dunno (yet) what "locolor" means. First guess is it's _less_ than 24-bit color.

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".

I should have been more specific. :)
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.
Richard.
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.
