RepPixel
Class
Des cription
Color
Replicates a pixel throughout a 32-bit integer. The output of this function is in suitable form
to be used as input to the SetColor0(), SetColor1(), or Set_Pmask() functions.
For example, given a pixel size of 4 and an input value of 5, the return value is
0x55555555. An input value of 0x01234567 produces a return value of 0x77777777, and
so on.
Syntax
uint32 RepPixel( uint32 pixelvalue )
pixelvalue
Return value
Example
Given a pixel size of n bits, then LSBs of the input argument (the 32-n MSBs are ignored)
are replicated 32/n times to fill the 32-bit return argument.
This example draws an image that has a filled rectangle at the uppet left corner of the
screen.
/* Establish number of image versions. */
SetVersions(0);
/* Setup look-up-table for colors white and black and colors red,
green and blue */
SetLut(BW|HUERGB);
init_canvas();
/* Clear the screen with black. */
BlackFillVuport();
SetColor1(RepPixel(4));
FillRect(100, 100, 0, 0);
