Possible errors are in the GDK_PIXBUF_ERROR and G_FILE_ERROR domains.
The image will be scaled to fit in the requested size, optionally preserving
the image's aspect ratio. gdkPixbufNewFromFileAtScale(filename, width, height, preserve.aspect.ratio, .errwarn = TRUE)filenamewidthheightpreserve.aspect.ratioTRUE to preserve the image's aspect ratioGdkPixbuf] 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.errorwidth 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.
