Re: convert to dithered 3 bit (8 color) bitmap?

Looking up isn't enough. It can't open image files which use palettes, be it BMP or PNG.

Re: convert to dithered 3 bit (8 color) bitmap?

Thank you. Now about loading the dithered palettized images back to ImageMagick to convert it to an image not using a palette, are you guys getting the same error as me? or can you successfully convert these images? The reason I want to do this is I want to use Blender to save the frames to a video ...

Re: convert to dithered 3 bit (8 color) bitmap?

I still can't find a way to set the save locations of extracted color channels. Not sure why you would need to do that. I mentioned this, And how can I set the locations and names of the extracted channel files to save? "-separate" saves all 3 channels in one folders and names them itself. I could ...

Re: convert to dithered 3 bit (8 color) bitmap?

Thank you. What colors are in the "saturated colors" palette? Red, green, blue, cyan, magenta, yellow, white, black? I still can't find a way to set the save locations of extracted color channels. Also, I'm unable to save back any image I've converted to a BMP which uses palettes. When converting ...

Re: convert to dithered 3 bit (8 color) bitmap?

For now I've just written a Python script that runs a windows shell command inside a loop, not a good way to do it but will do for now. How to do ordered dithering and still use custom 8 color pallete? And how can I set the locations and names of the extracted channel files to save? "-separate ...

Re: convert to dithered 3 bit (8 color) bitmap?

I checked the Wand sourcecode and it seems there's no wrapper around that function. I also checked "PythonMagick" library which seems to be a wrapper around the C++ "Magick++" library. I found the function Image.map there which is also made available in PythonMagick, but it only seems to allow Floyd ...

Re: convert to dithered 3 bit (8 color) bitmap?

I'm currently using http://docs.wand-py.org/en/0.4.0/ but any will do.

And how to do ordered dithering and still use custom 8 color pallete?

Re: convert to dithered 3 bit (8 color) bitmap?

Thank you.

What about the ImageMagick API? I tried writing a Python program to automate conversion of files in folders, but I can't find where the '-remap' functionality of the convert.exe program is in the API.
