newFromFileAtScale

fun newFromFileAtScale(filename: String, width: <Error class: unknown class>, height: <Error class: unknown class>, preserveAspectRatio: Boolean): <Error class: unknown class><Pixbuf>

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.

Return

A newly-created pixbuf

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

preserveAspectRatio

TRUE to preserve the image's aspect ratio
