| the current videomode, use function 61. |
| ====================================================================== |
| =============== Function 36 - read screen area. =============== |
| ====================================================================== |
| Paramters: |
| * eax = 36 - function number |
| * ebx = pointer on the previously allocated area of memory, |
| where will be placed the image in the format BBGGRRBBGGRR... |
| * ecx = [size on axis x]*65536 + [size on axis y] |
| * edx = [coordinate on axis x]*65536 + [coordinate on axis y] |
| Returned value: |
| * function does not return value |
| Remarks: |
| * Coordinates of the image are coordinates of the upper left corner |
| of the image relative to the window. |
| * Size of the image in bytes is 3*xsize*ysize. |
