The information in this article applies to:

  • The C Run-time (CRT), included with: 

        - Microsoft C for MS-DOS, versions 6.0, 6.0a, and 6.0ax
    - Microsoft C/C++ for MS-DOS, version 7.0
    - Microsoft Visual C++ for Windows, version 1.0

The _imagesize() function calls _getvideoconfig() to determine the number of bits required to store a pixel given the CURRENT video mode. If you are calling _imagesize() prior to calling _setvideomode(), an unexpected result is returned by _imagesize().

In summary, do the following in order:

  1. _setvideomode()

  2. _imagesize()

  3. _getimage() and putimage()
