![]() QuartzCode is here to help We offer many products to assist you in your daily tasks. QuartzCode offers an array of applications regardless of your business size Owning a business can be stressful. Allowing you the ability to reduce clutter and paperwork.

All QuartzCode applications offer emailing of invoices and bills. The right way to do that seems to make JFrame and display it when certain element is clicked. You can for example imagine you were asked to re-invent dropdown menu. ] īasically: instead of using clipping paths, simply use blendmode.Īnd in this example the gradient is cached in a CGLayer. Display JFrame relative to elements on other main JFrame. NSRect inner = NSInsetRect(, borderSize, borderSize) Here's the basic code for creating the left side trapezoidal region: NSRect outer = Using NSBezierPath to create the trapezoidal regions would be fairly straightforward, and you would only have to perform four drawing operations. But for this to work, I think I'd need to set up a trapezoidal clipping area for each side first, so that the gradients would be mitered at the corners. Use CGGradient in linear mode, once for each side. Once the code finishes drawing, Cocoa and the. CIColor. ![]() Seems like there should be a way to use path stroking to do this, but it doesn't seem like there's a way to define a pattern that's oriented differently on each side. Subsequent drawing calls inside the window or view take place relative to this local coordinate system. I am trying to use QuartzCore Framework but when adding this framework to my iPhone application, I am told that the files (e.g. Use CGGradient in linear mode, once for each side.I can't think of a simpler approach, but I have to do all of the gradient calculations myself, and it might be a lot of graphics operations. Draw a series of concentric rectangles, each subsequent one lighter in color, and inset by 1px on each side.So I'm wondering what the best approach would be. Unfortunately, as far as I can tell, Core Graphics doesn't provide rectangular gradients (either with CGGradient or CGShading). This would essentially be a rectangular gradient: a black line around the frame, fading to white about 10-20 pixels in. As the background for one of the views in my app, I'd like to draw a fairly simple rectangular border just inside its frame.
