mcychan / nquantcpp Goto Github PK

Hi,

The source contains some hints that it once compiled on Linux, but currently it does not because it depends on GdiPlus. Is there a way I don't know about to compile it? I looked into libgdiplus but that doesn't provide any headers.

If not, would it suffice to replace the GdiplusStartup code in main and write a minimal Bitmap class from scratch, or does it need more from GDI? What do you think?

Regards,
Ivo

There doesn't seem to be an option to quantize using the Dennis Lee v3 algorithm in the executable. The options listed are PNN, PNNLAB, NEU, WU, EAS, SPA, DIV, MMC, OTSU, but none of them seem to be for that algorithm. If it actually isn't available from the exe, could you add it?

$ nQuantCpp.exe image.png /m 128
Converted image: C:\Test\image-DIVquant128.png
Converted image: C:\Test\image-PNNquant128.png
Converted image: C:\Test\image-NEUquant128.png

And then suddenly… Kaboom!

extbins become negative if nMaxColors greater then maxbins

maybe should use absolute value?

uint extbins = std::abs(maxbins - nMaxColors);

could you make each color quantization algorithms can be chosen by command line? that way just have one image as a result. Besides, could you explain what type of files this admits? I was testing with png and tif, and both work.
Thank you.
