TFMXCanvasHelper.RoundRect(Single,Single,Single,Single,Single,Single,Single) Method |
Scroll Prev Top Next More |
Draws a rectangle with rounded corners on the canvas.
Use RoundRect to draw a rounded rectangle using Pen and fill it with Brush. The rectangle will have edges defined by the points (X1,Y1), (X2,Y1), (X2,Y2), (X1,Y2), but the corners will be shaved to create a rounded appearance. The curve of the rounded corners matches the curvature of an ellipse with width X3 and height Y3.
To draw an ellipse instead, use Ellipse. To draw a true rectangle, use Rectangle.

This FMX version of the method adds a default Opacity parameter at the end of the parameters. This allows you to take advantage of the FMX ability to draw transparently to the canvas. Alternatively, don't set this parameter and it works exactly like the VCL TCanvas method. |
