About
Abstract
A GRQuad is a graphic node visualizing a rectangle with potentially a texture. The Quad is form (-1,-1) to (1,1). We must transform it the transformation matrix to get the size and position, we expect.
To create a GRQuad it exists two functions:
quad=cve.viewer.GRQuad(image)
where :
- image is a png or jpg file. It may be None and a cvetexture may be associated through methods

quad=cve.viewer.GRQuadFromCamera(camera)
where :
- Camera port number (from 0 to n-1) when n is the number of camera connected to the computer
In the last case the run method start/stop camera capture.
