# GraphicsMagick Bugs

The following bugs are known to exist in GraphicsMagick. Please report any additional bugs to the GraphicsMagick bug tracker at SourceForge.

> - Affine transforms on a non-apaque image results in an image which looks like it has pre-multiplied alpha applied to the colors (reported by Timothy Hunter).
> - BMP reader is not working for some obscure low-color packed files.
> - DPX reader/writer does not properly handle subformats where row samples spill over the storage word boundary. This means that single-channel/grayscale 10-bit DPX files will only work for widths evenly divisible by three. (SF 1533184)
> - MPC "format" severely misbehaves when converting to another MPC file or when outputting to a format which requires that the pixels or colormap be modified (which would want to modify the read-only MPC input file).
> - PSD reader is not working for some files. Can fix by extracting the already rendered image from the PSD file rather than the layers.
> - Scitex reader is not working for some files.
> - SVG writer works only if you are particularly luckly.
> - SVG reader mishandles basic units and many other syntax elements (SF 1231547, 1298606).
> - BlobToImage ignores the value of the 'magick' parameter. I don't know how to fix this due to how things work. (SF 1839932).
> - Text annotation options do not work perfectly (SF 1539050, 1539052, 1539059)
> - Due to long-standing design decision, Magick++ Color class may not be used to assign color to transparent black since it is considered to be an invalid color.
