annotate libinterp/dldfcn/__magick_read__.cc @ 17228:2f1729cae08f
Initial support for writing of floating point and uint32 images.
* __magick_read__.cc (img_float2uint): new function to convert floating
point values in the range [0 1] to uint.
(encode_indexed_images): add new case for images with uint32 values;
avoid overflowing of div_factor for big bitdepth.
(__magick_write__): add new case for uint32 and floating point images.
