Timing

As part of debugging an application, you can obtain information about the amount of time required to complete repetitive DrawDib operations. The DrawDibTime1RYG_4U function returns timing information for the following operations:

    Drawing a bitmap

    Decompressing a bitmap

    Dithering a bitmap

    Stretching a bitmap

    Transferring a bitmap by using the BitBlt31VU054 function

    Transferring a bitmap by using the StretchDIBitsD.WWU6 function

After retrieving a set of values, DrawDibTime1RYG_4U resets the count and value for each operation.

The DrawDibTime function is available only in the debug version of the DrawDib functions.
