gdkPixbufNewFromFileAtSize

Description

Creates a new pixbuf by loading an image from a file. The file format is detected automatically. If NULL is returned, then error will be set. Possible errors are in the GDK_PIXBUF_ERROR and G_FILE_ERROR domains.

Usage

gdkPixbufNewFromFileAtSize(filename, width, height, .errwarn = TRUE)

Arguments

`filename`	Name of file to load, in the GLib file name encoding
`width`	The width the image should have or -1 to not constrain the width
`height`	The height the image should have or -1 to not constrain the height
`.errwarn`	Whether to issue a warning on error or fail silently

Details

The image will be scaled to fit in the requested size, preserving the image's aspect ratio. Note that the returned pixbuf may be smaller than width x height, if the aspect ratio requires it. To load and image at the requested size, regardless of aspect ratio, use gdkPixbufNewFromFileAtScale. Since 2.4

Value

A list containing the following elements:

`retval`	[`GdkPixbuf`] A newly-created pixbuf with a reference count of 1, or `NULL` if any of several error conditions occurred: the file could not be opened, there was no loader for the file's format, there was not enough memory to allocate the image buffer, or the image file contained invalid data.
`error`	Return location for an error
