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
Parameters
filename-
Type:
const char*Name of file to load, in the GLib file name encoding.
The data is owned by the caller of the function. The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows. width-
Type:
intThe width the image should have or -1 to not constrain the width.
height-
Type:
intThe height the image should have or -1 to not constrain the height.
error-
Type:
GError **The return location for a recoverable error.
The argument can be NULL.If the return location is not NULL, then you must initialize it to aNULLGError*.The argument will be left initialized to NULLby 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.
Return value
Type: GdkPixbuf
A newly-created pixbuf.
| The caller of the function takes ownership of the data, and is responsible for freeing it. |
The return value can be NULL. |
