to4bit

to4bit ( integer Input, integer Output )

Use this function to convert an image or selection into a 16-color bitmap. To reduce the number of colors in the image down to 16, this function uses the median-cut color quantization algorithm searching for color clusters in the RGB coordinate space.

Parameters

Input

An integer between 0 and 116 specifying the input image frame number. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.

Output

An integer between 1 and 116 specifying the output image frame number. Values in the range of 100-116 correspond to hidden frames.

Error flags

ERR_OK

The flag set if successful.

ERR_FAILED

The flag set if failed.
