| Value | Meaning |
|---|---|
| COLOR_TYPE_RGB1 | each pixel has red, green and blue samples. |
| COLOR_TYPE_RGBA2 | each pixel has red, green and blue samples and an alpha value. |
| COLOR_TYPE_MASK255 | mask for the colortype flags of the enum. |
| SAMPLE_WIDTH_865536 | each sample has 8 bits. |
| SAMPLE_WIDTH_MASK983040 | mask for the sample width flags of the enum. |
| ENCODING_RAW16777216 | the pixel data is in raw form. |
| ENCODING_RLE33554432 | 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. |
| ENCODING_MASK251658240 | mask for the encoding flags of the enum. |
An enumeration containing three sets of flags for a #GdkPixdata struct: one for the used colorspace, one for the width of the samples and one for the encoding of the pixel data.
