Important Notice
The pages on this site contain documentation for very old MS-DOS software,
purely for historical purposes.
If you're looking for up-to-date documentation, particularly for programming,
you should not rely on the information found here, as it will be woefully
out of date.
getpixel, _getpixel_w
◄Summary► ◄Example► ◄Up► ◄Contents► ◄Index► ◄Back►
────────────────────────────────────────────────────────────────────────────
The functions in the getpixel family return the pixel value (a
color index) at a specified location. The getpixel function uses
the view coordinates (<x>, <y>). The getpixel_w function uses the
window coordinates (<wx>, <wy>).
For both getpixel and getpixel_w, the ranges of possible pixel
values and their color translations are determined by the current
video mode and palette, respectively.
Return Value
If successful, the function returns the color index. If the
function fails (for example, the point lies outside the clipping
region, or the program is in text mode), it returns -1.
