StampBitsPerPixel Property

Summary

Gets and sets the bit depth for the stamp image.

Syntax

Objective-C

C++/CLI

Java

Python

public int StampBitsPerPixel { get; set; }

@property (nonatomic, assign) NSUInteger stampBitsPerPixel;

public int getStampBitsPerPixel() 
public void setStampBitsPerPixel(int value)

public: 
property int StampBitsPerPixel { 
   int get(); 
   void set (    int ); 
}

StampBitsPerPixel # get and set (CodecsWebpSaveOptions)

Property Value

The default value is 24.

The bit depth for the stamp image. Currently, the only value supported is 24.

Remarks

The stamp is saved only if all the following are true:

CodecsWebpSaveOptions.SaveWithStamp = true
CodecsWebpSaveOptions.StampWidth > 0
CodecsWebpSaveOptions.StampHeight > 0
StampBitsPerPixel = 24

If any of the above conditions are not met, the stamp is not saved.

Example

using Leadtools; 
using Leadtools.Codecs; 
 
using Leadtools.ImageProcessing.Core; 
 
public void TestSaveWebpExample() 
{ 
   // This example saves 3 files with various stamp settings and quality factors 
   string srcFile = Path.Combine(LEAD_VARS.ImagesDir, @"sample1.cmp"); 
   string dstFile = Path.Combine(LEAD_VARS.ImagesDir, @"out-"); 
 
   using (RasterCodecs codecs = new RasterCodecs()) 
   using (RasterImage image = codecs.Load(srcFile, 1)) 
   { 
      // CodecsWebpOptions & CodecsWebpSaveOptions reference 
      codecs.Options.Webp.Save.SaveWithStamp = true; 
      codecs.Options.Webp.Save.StampBitsPerPixel = 24; 
 
      codecs.Options.Webp.Save.QualityFactor = 20; 
      codecs.Options.Webp.Save.StampWidth = 160; 
      codecs.Options.Webp.Save.StampHeight = 120; 
      // this file should have a stamp that is 160x120 
      codecs.Save(image, dstFile + "stamp160x120-q20.webp", RasterImageFormat.Webp, 0); 
 
      // this file should have a stamp that is 240x200 
      codecs.Options.Webp.Save.QualityFactor = 120; 
      codecs.Options.Webp.Save.StampWidth = 240; 
      codecs.Options.Webp.Save.StampHeight = 200; 
      codecs.Save(image, dstFile + "stamp240x200-q120.webp", RasterImageFormat.Webp, 0); 
 
      // this file should have no stamp 
      codecs.Options.Webp.Save.SaveWithStamp = false; 
      codecs.Options.Webp.Save.QualityFactor = 0; 
      codecs.Save(image, dstFile + "NoStamp-lossless.webp", RasterImageFormat.Webp, 0); 
   }
