Pixbuf.from_file_at_scale


Description:

[ CCode ( has_construct_function = false ) ]
[ Version ( since = "2.6" ) ]
public Pixbuf.from_file_at_scale (string filename, int width, int height, bool preserve_aspect_ratio) throws Error

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:

- the file could not be opened - there is no loader for the file's format - there is not enough memory to allocate the image buffer - the image buffer contains invalid data

The error domains are `GDK_PIXBUF_ERROR` and `G_FILE_ERROR`.

The image will be scaled to fit in the requested size, optionally preserving the image's aspect ratio.

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 aspect ratio, a `width` or `height` of -1 means to not scale the image at all in that dimension. Negative values for `width` and `height` are allowed since 2.8.

Parameters:

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

preserve_aspect_ratio

`TRUE` to preserve the image's aspect ratio

Returns:

A newly-created pixbuf
