Enumeration

GdkPixdata.PixdataType

Declaration

flags 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.
