information that describes an image in memory.
Details
typedef enum {
GDK_COLORSPACE_RGB
} GdkColorspace; |
This enumeration defines the color spaces that are supported by
the gdk-pixbuf library. Currently only RGB is supported.
GdkColorspace gdk_pixbuf_get_colorspace (const GdkPixbuf *pixbuf); |
Queries the color space of a pixbuf.
int gdk_pixbuf_get_n_channels (const GdkPixbuf *pixbuf); |
Queries the number of channels of a pixbuf.
gboolean gdk_pixbuf_get_has_alpha (const GdkPixbuf *pixbuf); |
Queries whether a pixbuf has an alpha channel (opacity information).
int gdk_pixbuf_get_bits_per_sample (const GdkPixbuf *pixbuf); |
Queries the number of bits per color sample in a pixbuf.
