Undocumented in source.
A function of this type is responsible for freeing the pixel array of a pixbuf. The Pixbuf.newFromData function lets you pass in a pre-allocated pixel array so that a pixbuf can be created from it; in this case you will need to pass in a function of GdkPixbufDestroyNotify so that the pixel data can be freed when the pixbuf is finalized.
Specifies the type of the function passed to Pixbuf.saveToCallback. It is called once for each block of bytes that is "written" by Pixbuf.saveToCallback. If successful it should return TRUE. If an error occurs it should set error and return FALSE, in which case Pixbuf.saveToCallback will fail with the same error.
This enumeration defines the color spaces that are supported by the gdk-pixbuf library. Currently only RGB is supported.
This enumeration describes the different interpolation modes that can be used with the scaling functions. GDK_INTERP_NEAREST is the fastest scaling method, but has horrible quality when scaling down. GDK_INTERP_BILINEAR is the best choice if you aren't sure what to choose, it has a good speed/quality balance.
These values can be passed to Pixbuf.xlibRenderToDrawableAlpha to control how the alpha channel of an image should be handled. This function can create a bilevel clipping mask (black and white) and use it while painting the image. In the future, when the X Window System gets an alpha channel extension, it will be possible to do full alpha compositing onto arbitrary drawables. For now both cases fall back to a bilevel clipping mask.
The possible rotations which can be passed to Pixbuf.rotateSimple. To make them easier to use, their numerical values are the actual degrees.
An enumeration which is used by Pixdata.toCsource to determine the form of C source to be generated. The three values GDK_PIXDATA_DUMP_PIXDATA_STREAM, GDK_PIXDATA_DUMP_PIXDATA_STRUCT and GDK_PIXDATA_DUMP_MACROS are mutually exclusive, as are GDK_PIXBUF_DUMP_GTYPES and GDK_PIXBUF_DUMP_CTYPES. The remaining elements are optional flags that can be freely added.
An enumeration containing three sets of flags for a gdkpixbuf.Pixdata struct: one for the used colorspace, one for the width of the samples and one for the encoding of the pixel data.
Magic number for gdkpixbuf.Pixdata structures.
Major version of gdk-pixbuf library, that is the "0" in "0.8.2" for example.
Micro version of gdk-pixbuf library, that is the "2" in "0.8.2" for example.
Minor version of gdk-pixbuf library, that is the "8" in "0.8.2" for example.
Contains the full version of the gdk-pixbuf header as a string. This is the version being compiled against; contrast with gdk_pixbuf_version
The length of a gdkpixbuf.Pixdata structure without the pixel_data pointer.
