* gdk-pixbuf-scale: Fix retval introspection for scale_simple()Iñaki García Etxebarria2017-11-281-1/+1
| | | | | | | Add nullable return introspection annotation for gdk_pixbuf_scale_simple() as per existing API documentation. https://bugzilla.gnome.org/show_bug.cgi?id=789934
* gdk-pixbuf-scale: Add a fast path for a no-op scalePhilip Withnall2017-01-101-0/+7
| | | | | | | | If calling gdk_pixbuf_scale_simple() with equal src and dest dimensions, there’s nothing to do, so just return a copy of the src pixbuf. Document the new fast path. https://bugzilla.gnome.org/show_bug.cgi?id=442452
* docs: Document existing scaling and transformation fast pathsPhilip Withnall2017-01-101-0/+5
| | | | | | There are not many, as far as I can see. https://bugzilla.gnome.org/show_bug.cgi?id=442452
* docs: Document the alpha blending function usedPhilip Withnall2017-01-101-0/+6
| | | | https://bugzilla.gnome.org/show_bug.cgi?id=442452
* docs: Use ‘alpha blending’ rather than ‘compositing’Philip Withnall2017-01-101-10/+12
| | | | | | | It’s a slightly more accurate term, as compositing seems to mostly refer to bit-mask composition of two images, rather than blending. https://bugzilla.gnome.org/show_bug.cgi?id=442452

* Avoid integer overflow in gdk_pixbuf_rotate_simpleMatthias Clasen2015-08-241-1/+1
| | | | | Same as before: don't do ptr = base + y * rowstride if y and rowstride are integers.
* Add _new_from_bytes() and _read_pixels() API, handle read-only pixbufsColin Walters2014-07-181-18/+58
| | | | | | | | | | | | | | | | | | | | | GdkPixbuf is an old API that predates introspection and GBytes. It has some confusion around whether or not pixbuf data is mutable or not. The _new_from_data() API takes a *const* pointer, but it's not copied, and _get_pixels() returns a non-const copy of the same pointer. There are several cases where we get read-only data, such as a GResource. For language bindings, _new_from_data() doesn't work because the array may be a temporary copy only allocated for the call. In order to support a clean _new_from_bytes() API, we need to add the concept of a read-only pixbuf into the core. The fundamental hack here is that _get_pixels() now causes an implicit copy. For the cases where we don't want to copy, add a new gdk_pixbuf_read_pixels() that returns a proper const pointer. https://bugzilla.gnome.org/show_bug.cgi?id=732297

* Documentation: Migrate from old tmpl files.Jon Nordby2011-03-061-0/+72
