Description

public class

TFMXCanvasHelper

Class helper for FMX TCanvas to provide Vcl-specific method signatures to the canvas. This class helper makes porting VCL code to FMX much easier.

In addition to all the VCL TCanvas methods added, the class adds Pen and Brush properties. However, by necessity, the VCL Pen is not exactly like the FMX Stroke and the VCL Brush is not exactly like the FMX FIll.

The following methods do not work and silently do nothing:

• LineTo and MoveTo do not work (use DrawLine)

• Arc

• ArcTo

• Chord

• CopyRect

• Pie

public class

TRSStrokeHelper

Class helper for TStrokeBrush or TRSStroke.

Adds a VCL-like FMX.RS.CanvasHelper.TRSStrokeHelper.Width property.
