swf_viewport — Sets the drawing area


void swf_viewport(xmin, xmax, ymin, ymax);
double xmin: Minimum x width
double xmax: Maximum x width
double ymin: Minimum y width
double ymax: Maximum y width




By default the drawing area is that defined in swf_openfile(), however this value can be changed using this function so that only a portion of the canvas is drawn on.

In the example below, 'Hello World' is drawn on the main canvas, then the drawing area resized to 100x100 pixels only starting at the bottom left corner. This means the next string is drawn on the newly sized area and is therefore scaled appropriately.


Existing since version 4.0


Example 1296. Modify drawing area

swf_openfile ("test.swf", 100, 100, 30, 0.8, 0.8, 0.8);

swf_addcolor(1, 1, 1, 1);
swf_definefont(1, "Pix3");
Swf_definetext(2, "Hello World", 1);
swf_placeobject(2, 1);

swf_addcolor(0, 0, 0, 1);
swf_definetext(3, "Another World", 1);
swf_translate(0, -10,0);
swf_placeobject(3, 1);
