Methods and Functions

Detailed Description

The GdkImage type represents an area for drawing graphics. It has now been superceded to a large extent by the much more flexible GdkRGB functions. To create an empty GdkImage use gdkImageNew. To create a GdkImage from bitmap data use gdkImageNewBitmap(). To create an image from part of a GdkWindow use gdkDrawableGetImage. The image can be manipulated with gdkImageGetPixel and gdkImagePutPixel, or alternatively by changing the actual pixel data. Though manipulating the pixel data requires complicated code to cope with the different formats that may be used. To draw a GdkImage in a GdkWindow or GdkPixmap use gdkDrawImage. To destroy a GdkImage use gdkImageDestroy().

Structures

Convenient Construction

gdkImage is the equivalent of gdkImageNew.
