5.x 6.00 6.00a 6.00ax 7.00

MS-DOS

Summary:

In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version

7.0, 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()
