Syntax

Objective-C

C++/CLI

Java

Python

public bool SaveWithStamp { get; set; }

@property (nonatomic, assign) BOOL saveWithStamp;

public boolean getSaveWithStamp() 
public void setSaveWithStamp(boolean value)

public: 
property bool SaveWithStamp { 
   bool get(); 
   void set (    bool ); 
}

SaveWithStamp # get and set (CodecsWebpSaveOptions)

Property Value

Value	Description
true	To save with stamp.
false	To save without stamp. The default value is false.

Remarks

If SaveWithStamp is true, then set CodecsWebpSaveOptions.StampWidth, CodecsWebpSaveOptions.StampHeight properties to indicate the desired stamp size, and ensure CodecsWebpSaveOptions.StampBitsPerPixel is not 0.

Otherwise, if SaveWithStamp is false, the CodecsWebpSaveOptions.StampWidth, CodecsWebpSaveOptions.StampHeight and CodecsWebpSaveOptions.StampBitsPerPixel properties are ignored.

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); 
   }
