/* MCI_DGV_PUT_FRAME
|
|
|
|
The rectangle defined for MCI_DGV_RECT applies to the frame rectangle.
|
|
The frame rectangle specifies the portion of the frame buffer used as the destination of the video images obtained from the video rectangle.
|
|
The video should be scaled to fit within the frame buffer rectangle.
|
|
The rectangle is specified in frame buffer coordinates.
|
|
The default rectangle is the full frame buffer.
|
|
Specifying this rectangle lets the device scale the image as it digitizes the data.
|
|
Devices that cannot scale the image reject this command with MCIERR_UNSUPPORTED_FUNCTION.
|
|
You can use the MCI_GETDEVCAPS_CAN_STRETCH flag with the MCI_GETDEVCAPS command to determine if a device scales the image. A device returns FALSE if it cannot scale the image.
