[edit] Definition
INT drawing_stipple ( <INT stipples> )
Tells Fenix which pixels to draw of the coming drawings.
This is done by passing a 32bit value, each bit representing a pixel. Bit 0 represents the first pixels drawn, bit 1 represents the second, etc. When a 33rd pixel is to be drawn or not, bit 0 is checked and the cycle starts over. This means a value of 0xFFFFFFFF
(=2^32-1
) means normal operation, meaning all the pixels will be drawn.
Note that this works only for non-filled drawings. For draw_curve(), the pattern is not always visible for the higher smoothness levels.
[edit] Parameters
INT stipples - Which pixels to draw, repetitive 32bits. |
[edit] Returns
INT : true
[edit] Example
Program example; Private // int draw_id; Begin // Draw in background drawing_map(0,background); // Set stipplemode to display every other pixel. // binary code 0101 0101 0101 0101 0101 0101 0101 0101 // hex code 55555555h drawing_stipple(55555555h); // Draw two lines draw_line(10,10,190,10); draw_line(11,12,190,12); // Draw this funky pattern // binary code 0011 1100 0111 1100 1010 0001 1101 0011 // hex code 3C7CA1D3h drawing_stipple(3C7CA1D3h); // Draw two lines draw_line(10,20,190,20); draw_line(11,22,190,22); // Draw a circle draw_circle(100,100,50); // Draw a rectangle draw_rect(50,50,150,150); // Draw some lines draw_line( 50, 50,100,150); draw_line(100,150,150, 50); draw_line( 50,150,100, 50); draw_line(100, 50,150,150); // Draw two curves: one with high smoothness (bit pattern not visible) and one with low smoothness draw_curve( 200,200, 100,200, 100,150, 300,100,15); draw_curve( 200,200, 100,200, 100,150, 300,100,1); // Draw a filled circle draw_fcircle(20,180,15); // Draw a filled rectangle draw_box(50,180,80,195); // Wait for key ESC Repeat frame; Until(key(_ESC)) End
Used in example: drawing_map(), draw_line(), draw_circle(), draw_rect(), draw_curve(), draw_fcircle(), draw_box(), key()
