An enumeration containing three sets of flags for a gdkpixbuf.Pixdata struct: one for the used colorspace, one for the width of the samples and one for the encoding of the pixel data.
each pixel has red, green and blue samples.
each pixel has red, green and blue samples and an alpha value.
mask for the colortype flags of the enum.
each sample has 8 bits.
mask for the sample width flags of the enum.
the pixel data is in raw form.
the pixel data is run-length encoded. Runs may be up to 127 bytes long; their length is stored in a single byte preceding the pixel data for the run. If a run is constant, its length byte has the high bit set and the pixel data consists of a single pixel which must be repeated.
mask for the encoding flags of the enum.
