[Newbie] graph_on() and clearg()

Postby Eric Delapierre on Wed May 22, 2002 11:46 pm

hello,
I try this little program to understand the graph mode :
//mvt
library "PToolboxLib"

x=1;
y=50;
mvt(){
graph_on();
OpenBmpDb("image.pdb");

while (x<160){
x=x+1;
FastBmp(x,y,0);
sleep(100);
clearg();
}
main(){
mvt();
}
The program is running without problems, but i am not glad because the graphic blinks.
How can i do to get rid of this blink (the clearg() function clears all the screen and not my graphic form). Should i draw a empty image whose the position and size is the same form instead of the graphic form?
Is there any graphic function i didn't see?

Thxs all for your response.

See the graphics.c file in the toolbox release for examples of using buffering to eliminate the flash.
