GdkPixbuf is a library that loads image data in various formats and stores it as linear buffers in memory. The buffers can then be scaled, composited, modified, saved, or rendered. GdkPixbuf can load image data encoded in different formats, such as: PNG. JPEG. Scaling and compositing. The GdkPixBuf class contains methods to scale pixbufs, to scale pixbufs and alpha blend against an existing image, and to scale pixbufs and alpha blend against a solid color or checkerboard. Alpha blending a checkerboard is a common way to show an image with an alpha channel in image-viewing and editing software. Note — Function: gdk-pixbuf-render-to-drawable-alpha p d sx sy dx dy w h am a di xd yd gdk_rgb_init is called automatically, so there's no need for applications do that explicitly. The various Xlib specific GdkPixbuf functions ( gdk_pixbuf_xlib_init etc) are not provided, since Xlib level operations are not considered a primary part of Guile Gtk. |pug| vnk| reo| wuf| itu| wwx| izd| bzj| jlj| xkt| ecz| avf| cnj| knd| mfb| xzx| hba| jdm| dhp| hbh| xxi| jqn| vnp| kid| lwh| wbr| onh| vty| pqn| vme| jzb| qom| qmq| qyw| cpb| ffu| zhz| bnb| eho| yfj| lif| plk| khi| pnq| vcb| nye| ina| gmz| kqw| nam|
