    Hi ALL,

    In my application i want to draw Bezier curves which includes Drawing rectangle,Square,and text
    i am using view Based template in iphone application please can any body provide details regarding this, i have used code

    CGRect rect =CGRectMake(10,20,300,300);
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGContextClearRect(ctx, rect);
    CGContextSetRGBFillColor(ctx, 255, 0, 0, 1);
    CGContextFillRect(ctx, CGRectMake(10, 10, 50, 50));
    CGContextSetRGBFillColor(ctx, 0, 255, 0, 1);
    CGContextFillEllipseInRect(ctx, CGRectMake(100, 100, 25, 25));

    but its not drawing any thing on the screen, please any body provide tutorials from scratch to creat graphics.

    At a glance I'm noticing that your arguments to CGContextSetRGBFillColor are off; this function accepts floating point numbers between 0.0 and 1.0.

    Also make sure you're putting this code in the drawRect: method.

    I'd suggest looking at the Quartz Demo sample app.
