Syntax
INT isavi_SetImageSize (INT nAviID, INT cMode, INT Width, INT Height,
INT PosX, INT PosY, INT LineOffset)
Description
isavi_SetImageSize() sets the size and position of the area of interest which will be saved to the AVI file. Only
the defined area of interest of each frame will be saved. In addition, this function specifies the input color format of
the frames. You define these settings only once for the entire video.
Note
The supported input color formats are RGB32, RGB24, Y8 and raw Bayer. The output file will always be in RGB24
format, regardless of the input data format. For further information on the structure of the different color formats,
see the Appendix: Color and memory formats section.
Attention
When an area of interest is used, the width (Width) and height (Height) of the AOI must be at least 16 pixel. The
AOI width must be a multiple of 8.
