16bpp Image

Post by UmerMujtaba » 2017-08-10T00:52:14-07:00

Hey,

I am using ImageMagick to convert my images to .pnm format using

Code: Select all

magick convert input.png -colors 65536 output.pnm

and then used a utility given by TI named pnmtoc. this utility can convert .pnm file to .c file. The problem is that I am getting two different color depths in c file for different images. I want to get 16bpp color depth for both images.

One of the image output is 16bpp but for other i am getting 8bpp. I am using same command and same utility for both images but i dont understand why I am getting 8bpp for a certain image.
I think there is difference between two image but didn't get what is it. and how I can get 16bpp for both images?

Thanks

What is your IM version and platform? Is it Q16 compile? The proper syntax for IM 7 is magick without the convert following it. If you do not want dithered colors, then try

Code: Select all

magick input.png +dither -colors 65535 -depth 16 output.pnm
or

Code: Select all

magick PNG24:input.png +dither -colors 65535 -depth 16 output.pnm
or

Code: Select all

magick PNG24:input.png -depth 16 output.pnm
