FillColor Property

Summary

Gets or sets the background fill color.

Syntax

Objective-C

C++/CLI

Java

Python

public RasterColor FillColor { get; set; }

@property (nonatomic, copy) LTRasterColor *fillColor;

public RasterColor getFillColor(); 
public void setFillColor( 
   RasterColor rasterColor 
);

public: 
property RasterColor FillColor { 
   RasterColor get(); 
   void set (    RasterColor ); 
}

FillColor # get and set (HighQualityRotateCommand)

Property Value

A RasterColor object that specifies the background fill color.

Remarks

The FillColor property will only be used if HighQualityRotateCommandFlags.Resize is specified in the Flags property. Since a RasterImage is always a rectangular object, rotation will always increase the width and height of the image. The extra space will be filled with the color specified in FillColor.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core; 
 
public void HighQualityRotateCommandExample() 
{ 
   RasterCodecs codecs = new RasterCodecs(); 
 
   // Get an image 
   string tifFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1.tif"); 
   string normalRotateFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1_NormalRotated.tif"); 
   string highQualityRotateFileName = Path.Combine(LEAD_VARS.ImagesDir, "ocr1_HighQualityRotated.tif"); 
 
   int angle = 30 * 100; 
   RasterColor fillColor = RasterColor.FromKnownColor(RasterKnownColor.White); 
 
   // Load the image, rotate normally by 30 degrees and save 
   using (RasterImage image = codecs.Load(tifFileName)) 
   { 
      RotateCommand cmd = new RotateCommand(); 
      cmd.Angle = angle; 
      cmd.Flags = RotateCommandFlags.Resize | RotateCommandFlags.Bicubic; 
      cmd.FillColor = fillColor; 
      cmd.Run(image); 
      codecs.Save(image, normalRotateFileName, image.OriginalFormat, image.BitsPerPixel); 
   } 
 
 
   // Load the image, rotate with high quality by 30 degrees and save 
   using (RasterImage image = codecs.Load(tifFileName)) 
   { 
      HighQualityRotateCommand cmd = new HighQualityRotateCommand(); 
      cmd.Angle = angle; 
      cmd.Flags = HighQualityRotateCommandFlags.Resize | HighQualityRotateCommandFlags.BestQuality; 
      cmd.FillColor = fillColor; 
      cmd.Run(image); 
      codecs.Save(image, highQualityRotateFileName, image.OriginalFormat, image.BitsPerPixel); 
   } 
 
   // Now compare the saved TIF files and notice the difference in quality between 
   // the normal rotate and high quality 
 
   codecs.Dispose(); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images";
