| + | ====Syntax of setfillpattern ==== | ||
| + | <code c> | ||
| + | #include <graphics.h> | ||
| + | void setfillpattern(char *upattern, int color); | ||
| + | </code> | ||
| + | |||
| + | |||
| + | ==== Description of setfillpattern ==== | ||
| + | <code c> | ||
| + | setfillpattern is like setfillstyle, except that you use it to set a | ||
| + | user-defined 8x8 pattern rather than a predefined pattern. | ||
| + | upattern is a pointer to a sequence of 8 bytes, with each byte | ||
| + | corresponding to 8 pixels in the pattern. Whenever a bit in a pattern | ||
| + | byte is set to 1, the corresponding pixel is plotted. | ||
