| Hello IM-ers.
|
| On Imagemagick 6.3.5 (Q16, WinXP), I can do "identify -verbose
| my_tga_file.tga", and one line of the output states the number of colors
| the image has:
|
| identify my_tga_file.tga | grep Colors:
| Colors: 2274
|
|
| On Imagemagick 6.3.7 (again, Q16, WinXP), the color count is no longer
| part of the output. Is this deliberate?
|
| Is there an alternative, but equally easy way of obtaining the number of
| colors in am image? I'm only dealing with 32 bit tgas, and these are
| quite easy to parse by hand. So it's only a screen's worth of C to do
| it myself.
|
Alturnative ways, is to ask specifically for the number of colors...
identify -format %k image.png
Or generate a color map for the image...
convert image.png -unique-colors info:
The width of the resulting image is the number of unique colors
But it will also be listed with as a number with a 'c' on the end.
