Declaration [src]
GdkPixbuf*
gdk_pixbuf_new_from_file_at_size (
const char* filename,
int width,
int height,
GError** error
)
Description [src]
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, 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
gdk_pixbuf_new_from_file_at_scale()
.
Available since: 2.4

by the constructor if there are no errors.In case of error, the argument will be set to a newly allocated GError
; the caller will take ownership of the data, and be responsible for freeing it.
