About IGDI+
The free open source library allows quick and easy implementations of complex GDI+ applications, in a natural Delphi-friendly code.
For example, to make this:
... you write code like this:
procedure TForm1.FormPaint(Sender: TObject);
var
AGraphics : IGPGraphics;
AFont : IGPFont;
ALeftTopCorner : TGPPointF;
ARect : TGPRectF;
ARect1 : TGPRectF;
APath : IGPGraphicsPath;
begin
AGraphics := TGPGraphics.Create( Canvas );
AGraphics.SmoothingMode := SmoothingModeAntiAlias;
AGraphics.TextRenderingHint := TextRenderingHintAntiAlias;
ALeftTopCorner := MakePointF( 20, 20 );
AFont := TGPFont.Create( 'Microsoft Sans Serif', 40, [ fsBold ] );
ARect := AGraphics.GetStringBoundingBoxF( 'Welcome to IGDI+', AFont, ALeftTopCorner );
ARect1 := GPInflateRectF( ARect, 10, 10 );
// Draw a fancy rounded rectangle.
AGraphics.DrawRoundRectangleF(
TGPPen.Create( TGPLinearGradientBrush.Create( GPInflateRectF( ARect1, 2, 2 ), aclRed, aclBlue, LinearGradientModeVertical ), 4 ),
TGPPathGradientBrush.Create(
TGPGraphicsPath.Create().AddRoundRectangleF( ARect1, MakeSizeF( 20, 20 ) )
)
.SetInterpolationColorsArrays( [ aclGreen, aclCyan, aclYellow ], [ 0, 0.3, 1 ] )
.SetCenterPointF( MakePointF( 250, 50 ))
.SetFocusScales( 0.87, 0.2 ),
ARect1, MakeSizeF( 20, 20 ) );
// Draw a text with semitransparent shadow.
AGraphics.DrawString( 'Welcome to IGDI+',
AFont,
MakePointF( 23, 23 ),
TGPSolidBrush.Create( MakeARGBColor( 50, aclBlack )) )
.DrawString( 'Welcome to IGDI+',
AFont,
ALeftTopCorner,
TGPLinearGradientBrush.Create( ARect, aclRed, aclBlue, LinearGradientModeForwardDiagonal ));
// Draw a closed curve.
AGraphics.DrawClosedCurveF( TGPPen.Create( aclRed, 3 ), TGPSolidBrush.Create( aclBlue ),
[
MakePointF( 60, 160 ),
MakePointF( 150, 180 ),
MakePointF( 200, 140 ),
MakePointF( 180, 220 ),
MakePointF( 120, 200 ),
MakePointF( 80, 260 )
] );
// Draw a semitransparent star.
APath := TGPGraphicsPath.Create();
APath.AddLinesF(
[
MakePointF( 75, 0 ),
MakePointF( 100, 50 ),
MakePointF( 150, 50 ),
MakePointF( 112, 75 ),
MakePointF( 150, 150 ),
MakePointF( 75, 100 ),
MakePointF( 0, 150 ),
MakePointF( 37, 75 ),
MakePointF( 0, 50 ),
MakePointF( 50, 50 )
] );
AGraphics.TranslateTransform( 420, 30 )
.FillPath(
TGPPathGradientBrush.Create( APath )
.SetCenterColor( MakeColor( 200, 255, 0, 0))
.SetSurroundColors(
[
MakeColor(80, 0, 0, 0),
MakeColor(80, 0, 255, 0),
MakeColor(80, 0, 0, 255),
MakeColor(80, 255, 255, 255),
MakeColor(80, 0, 0, 0),
MakeColor(80, 0, 255, 0),
MakeColor(80, 0, 0, 255),
MakeColor(80, 255, 255, 255),
MakeColor(80, 0, 0, 0),
MakeColor(80, 0, 255, 0)
] ),
APath );
// Draw rotated ellipse.
AGraphics.ResetTransform()
.TranslateTransform( 300, 160 )
.RotateTransform( 30 )
.DrawEllipseF(
TGPPen.Create( aclRed, 3 ),
TGPLinearGradientBrush.Create( MakePointF( 0, 0 ), MakePointF( 20, 20 ), aclYellow, aclGreen )
.SetWrapMode( WrapModeTileFlipX ),
0, 0, 200, 80 );
end;
