Fore Example

Executing the example requires a form with the button named Button1 and the ImageBox component named ImageBox1. Add links to the Drawing, Forms system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

BMP: IGxBitmap;

Graph: IGxGraphics;

GraphClass: GxGraphicsClass;

Font: IGxFont;

Brush: IGxBrush;

Begin

BMP := GxBitmap.CreateNew(ImageBox1.ClientWidth, ImageBox1.ClientHeight, GxPixelFormat.Unknown);

Font := New GxFont.Create("Times New Roman", 16, GxFontStyle.BoldItalic, GxUnit.World);

Brush := New GxSolidBrush.Create(GxColor.FromName("Red"));

GraphClass := New GxGraphics.Create;

Graph := GraphClass.FromImage(BMP);

Graph.DrawTextW("PROGNOZ", Font, Brush, 0, 0);

Graph.SetScale(10, 10);

Graph.DrawTextW("PROGNOZ", Font, Brush, 0, 0);

ImageBox1.Image := BMP;

End Sub Button1OnClick;

After executing the example clicking the button displays a new bitmap in the ImageBox component where two "PROGNOZ" labels are rendered with different scales according to the settings.
