y	The y-Coordinate of the top left corner to draw the image
xoffset	The x-Coordinate on the pixy image from where on you want the frame data
yoffset	The y-Coordinate on the pixy image from where on you want the frame data
width	The width of the image recorded from pixy

	)

Receives a cropped frame from pixy and saves it to the given file in the 24bit (b,g,a) format.

Parameters

handle	The file to write the data to. The file must be open and it should be seeked to the right position.
xoffset	The x-Coordinate on the pixy image from where on you want the frame data
yoffset	The y-Coordinate on the pixy image from where on you want the frame data
width	The width of the image recorded from pixy

int pixy_save_full_frame ( FILE_HANDLE * handle )

Receives a fullsized frame from pixy and saves it to the given file in the 24bit (b,g,a) format. Use this method to write the bitmap-data part of a windows bitmap (.bmp). This method will neither open nor close the passed file.

Parameters

handle The file to write the data to. The file must be open and it should be seeked to the right position.
