Fields:

Name	Description
Reserved0	This field is not currently used and must be set to 0.
Reserved1 Reserved2 Reserved3 Reserved4 Reserved5 Reserved6 Reserved7 Reserved8	These fields are not used and must be set to NULL.
PicFlags	Not used specifically by this opcode.
PicFlags2	Not used specifically by this opcode.
InStride	Set to the input image line width in bytes including padding, if any, for each line; or set to 0, and the opcode will return its calculated value, 32-bit aligned, at REQ_INIT.
ULCornerX ULCornerY URCornerX URCornerY LRCornerX LRCornerY LLCornerX LLCornerY	Set to the (X,Y) coordinates of the four corners (specified clockwise: Upper Left, Upper Right, Lower Right, Lower Left) of the object whose perspective is to be adjusted. If the app sets all fields to 0 before REQ_EXEC, then during REQ_EXEC the opcode will automatically find the corners and return them in these fields to the app at the first RES_PUT_NEED_SPACE request. Then it will use the values in these fields, either the corners it found or the corners supplied by or changed by the app, to drive the perspective transformation.
OutWidth OutHeight OutStride	Set to the desired width, height, and stride of the output image. If the app sets these fields to 0 before REQ_EXEC, then during REQ_EXEC the opcode will automatically determine suitable values for the output image and return them in these fields to the app at the first RES_PUT_NEED_SPACE request. OutStride returned by the opcode includes padding at the end of the line to be 32-bit aligned. Then it will use the values in these fields, either the dimensions it found or the dimensions supplied by or changed by the app, to drive the perspective transformation.
