struct GdkPixbuf::PixbufLoader::SizePreparedSignal

Overview

This signal is emitted when the pixbuf loader has been fed the initial amount of data that is required to figure out the size of the image that it will create.

Applications can call gdk_pixbuf_loader_set_size() in response to this signal to set the desired size to which the image should be scaled.

Defined in:

lib/gi-crystal/src/auto/gdk_pixbuf-2.0/pixbuf_loader.cr
