The trimmer can be programmed to re-define a new source image within the input video frame sent from an upstream module before it is sent to the scaling sub-modules. This feature enables small area zoom out, source pan/scan, or removal of unwanted area in the video (such as black box / curtains / noisy line-21 video) without modifying the VPDMA parameters.
Horizontal and vertical offset is set through VPE_CFG_SC25[26:16] CFG_OFF_W and VPE_CFG_SC25[10:0] CFG_OFF_H registers.
Width and height are set through VPE_CFG_SC24[26:16] CFG_ORG_W and VPE_CFG_SC24[10:0] CFG_ORG_H registers.
