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;

Format: IGxStringFormat;

r: IGxRectF;

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"));

Format := New GxStringFormat.Create;

Format.Alignment := GxStringAlignment.Center;

Format.LineAlignment := GxStringAlignment.Center;

Format.Trimming := GxStringTrimming.None;

GraphClass := New GxGraphics.Create;

Graph := GraphClass.FromImage(BMP);

r := New GxRectF.Create(0, 0, 0, 0);

r := Graph.MeasureTextRF("PROGNOZ", Font, r, Null);

r.Width := r.Width / 2;

Graph.DrawTextRF("PROGNOZ", Font, Brush, r, Format);

ImageBox1.Image := BMP;

End Sub Button1OnClick;

After executing the example clicking the button in the ImageBox component displays the new bitmap with rectangle truncated by width where the "PROGNOZ" label with corresponding defined settings is rendered in the middle.
