Thiago Santos	6560248be9	geometrictransform: Precalculate mapping array ... Precalculate when setting caps the warping map to avoid recalculating it every buffer	2010-06-04 15:31:19 -03:00
Thiago Santos	1250a7406d	geometrictransform: Accept any rgb or gray ... Using gstvideo functions geometrictransform can handle rgb or gray, put that on template caps	2010-06-04 15:31:19 -03:00
Thiago Santos	525aae23dc	geometrictransform: Rename some variables for clarity ... Renames some variables and adds a minimum doc to the mapping function for a little clarity. Also uses gstvideo functions for the row and pixel strides instead of hardcoded values	2010-06-04 15:31:18 -03:00
Thiago Santos	b7660b122c	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)	2010-06-04 15:31:18 -03:00
