geometrictransform: New plugin for geometric transforms Adds a new plugin that has elements that perform geometric transformations to images. By geometric transformations I mean that the operations are functions that given the output pixel position, get the pixel position in the input image. This pixel is then copied from input to output. The gstgeometrictransform baseclass makes it easy to write such elements. It boils down to write the mapping function and exposing properties Already added the first of the elements, 'pinch'. It's a common effect in image editors, like gimp (distort -> pinch)

geometrictransform: new filter "stretch" Ports gleffects "stretch" filter to geometrictransform. Shrinks the image around the center and gradually return to normal zoom creating funny caricatures. https://bugzilla.gnome.org/show_bug.cgi?id=625722

#include "gstbulge.h"
geometrictransform: new filter "tunnel" Ports gleffects "tunnel" filter to geometrictransform. Do nothing in a circle around the center and zoom outside. https://bugzilla.gnome.org/show_bug.cgi?id=625722
2010-08-02 08:46:44 +00:00
#include "gsttunnel.h"
geometrictransform: new filter "square" Ports gleffects "square" filter to geometrictransform. Maps a region around the center into a zoomed square and smoothly get back to normal zoom. With faces it makes a funny "cube-face" effect. https://bugzilla.gnome.org/show_bug.cgi?id=625722

#include "gstsquare.h"

geometrictransform: new filter "fisheye" Ports gleffects "fisheye" filter to geometrictransform. Fake fisheye lens filter. Somewhat empiric implementation because I didn't find any good algorithm that does it with nice results. https://bugzilla.gnome.org/show_bug.cgi?id=625722

geometrictransform: Add a 2D perspective transform plugin The perspective plugin applies a 2D perspective (also called projective) transform to the frame buffer. A perspective transform can be used for instance to perform keystone correction when playing the content with a video projector. https://bugzilla.gnome.org/show_bug.cgi?id=710810
