Turbo C Graphics - getfillsettings function

---

 

getfillsettings is used to get the current fill style and color values set by setfillstyle function. It accepts one input argument as the address of fillsettingstype struct. This struct has two member variables namely pattern and color. The possible pattern - style values are, EMPTY_FILL, SOLID_FILL, LINE_FILL, LTSLASH_FILL, SLASH_FILL, BKSLASH_FILL, LTBKSLASH_FILL, HATCH_FILL, XHATCH_FILL, INTERLEAVE_FILL, WIDE_DOT_FILL, CLOSE_DOT_FILL, USER_FILL

 

The possible color values are from 0 - 15 BLACK, BLUE, GREEN, CYAN, RED, MAGENTA, BROWN, LIGHTGRAY, DARKGRAY, LIGHTBLUE, LIGHTGREEN, LIGHTCYAN, LIGHTRED, LIGHTMAGENTA, YELLOW, WHITE

 

Look at the following lines of code in the given example: Initially setfillstyle is used to set the SOLID_FILL and WHITE color. Then it got changed immediately with user defined pattern (0xFF or 255) that also represents SOLID_FILL with BLUE color. You can change the array values of upattern_solid with any other values to change the pattern. Now getfillsettings would retrive the recently set values by setfillpattern - USER_FILL (12) and BLUE (1).

 

      setfillstyle(SOLID_FILL, WHITE);

      // The above fillstyle is modifie with the user defined pattern.

      setfillpattern(upattern_solid, BLUE);

      getfillpattern(patternbuffer);

      getfillsettings(&fstype);
