Enumeration
GdkPixdata.PixdataType
Description [src]
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.
Members
Name | Description |
---|---|
GDK_PIXDATA_COLOR_TYPE_RGB |
each pixel has red, green and blue samples. |
GDK_PIXDATA_COLOR_TYPE_RGBA |
each pixel has red, green and blue samples and an alpha value. |
GDK_PIXDATA_COLOR_TYPE_MASK |
mask for the colortype flags of the enum. |
GDK_PIXDATA_SAMPLE_WIDTH_8 |
each sample has 8 bits. |
GDK_PIXDATA_SAMPLE_WIDTH_MASK |
mask for the sample width flags of the enum. |
GDK_PIXDATA_ENCODING_RAW |
the pixel data is in raw form. |
GDK_PIXDATA_ENCODING_RLE |
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. |
GDK_PIXDATA_ENCODING_MASK |
mask for the encoding flags of the enum. |
