Package: gdk-pixbuf

Function gdk-pixbuf-new-from-file-at-scale

Lambda List

gdk-pixbuf-new-from-file-at-scale (filename width height preserve)

Arguments

filename -- a string with the name of the file to load, in the GLib file name encoding
width -- an integer with the width the image should have or -1 to not constrain the width
height -- an integer with the height the image should have or -1 to not constrain the height
preserve -- true to preserve the aspect ratio of the image

Return Value

A newly created gdk-pixbuf object, or nil if any of several error conditions occurred: the file could not be opened, there was no loader for the format of the file, there was not enough memory to allocate the image buffer, or the image file contained invalid data.

Details

Creates a new pixbuf by loading an image from a file. The file format is detected automatically. The image will be scaled to fit in the requested size, optionally preserving the aspect ratio of the image.

When preserving the aspect ratio, a width of -1 will cause the image to be scaled to the exact given height, and a height of -1 will cause the image to be scaled to the exact given width. When not preserving the aspect ratio, a width or height of -1 means to not scale the image at all in that dimension.
