Pixbuf.from_stream_at_scale
Description:
[ Version ( since = "2.14" ) ]
public Pixbuf.from_stream_at_scale (InputStream stream, int width, int height, bool preserve_aspect_ratio, Cancellable? cancellable = null) throws Error
Creates a new pixbuf by loading an image from an input stream.
The file format is detected automatically. If `NULL` is returned, then error will be set. The cancellable can be used
to abort the operation from another thread. If the operation was cancelled, the error `G_IO_ERROR_CANCELLED` will be returned. Other possible
errors are in the `GDK_PIXBUF_ERROR` and `G_IO_ERROR` domains.
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. If both `width` and `height` are given, this function will behave as if the smaller of the two values is passed as -1.
When not preserving aspect ratio, a `width` or `height` of -1 means to not scale the image at all in that dimension.
The stream is not closed.
Parameters:
| stream |
a `GInputStream` to load the pixbuf from |
| 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 |
| cancellable |
optional `GCancellable` object, `NULL` to ignore |
Returns:
|
A newly-created pixbuf |
