Encoder.SaveFlag Field

An Encoder object that is initialized with the globally unique identifier for the save flag parameter category.

[Visual Basic]
Public Shared ReadOnly SaveFlag As Encoder
[C#]
public static readonly Encoder SaveFlag;
[C++]
public: static Encoder* SaveFlag;
[JScript]
public static var SaveFlag : Encoder;

Example

[C#] The following example creates three Bitmap objects: one from a BMP file, one from a JPEG file, and one from a PNG file. The code saves all three images in a single, multiple-frame TIFF file.

[C#] 
using System;
using System.Drawing;
using System.Drawing.Imaging;
class Example_MultiFrame
{
public static void Main()
{
Bitmap multi;
Bitmap page2;
Bitmap page3;
ImageCodecInfo myImageCodecInfo;
Encoder myEncoder;
EncoderParameter myEncoderParameter;
EncoderParameters myEncoderParameters;
// Create three Bitmap objects.
multi = new Bitmap("Shapes.bmp");
page2 = new Bitmap("Iron.jpg");
page3 = new Bitmap("House.png");
// Get an ImageCodecInfo object that represents the TIFF codec.
myImageCodecInfo = GetEncoderInfo("image/tiff");
// Create an Encoder object based on the GUID
// for the SaveFlag parameter category.
myEncoder = Encoder.SaveFlag;
// Create an EncoderParameters object.
// An EncoderParameters object has an array of EncoderParameter
// objects. In this case, there is only one
// EncoderParameter object in the array.
myEncoderParameters = new EncoderParameters(1);
// Save the first page (frame).
myEncoderParameter = new EncoderParameter(
myEncoder,
(long)EncoderValue.MultiFrame);
myEncoderParameters.Param[0] = myEncoderParameter;
multi.Save("Multiframe.tiff", myImageCodecInfo, myEncoderParameters);
// Save the second page (frame).
myEncoderParameter = new EncoderParameter(
myEncoder,
(long)EncoderValue.FrameDimensionPage);
myEncoderParameters.Param[0] = myEncoderParameter;
multi.SaveAdd(page2, myEncoderParameters);
// Save the third page (frame).
myEncoderParameter = new EncoderParameter(
myEncoder,
(long)EncoderValue.FrameDimensionPage);
myEncoderParameters.Param[0] = myEncoderParameter;
multi.SaveAdd(page3, myEncoderParameters);
// Close the multiple-frame file.
myEncoderParameter = new EncoderParameter(
myEncoder,
(long)EncoderValue.Flush);
myEncoderParameters.Param[0] = myEncoderParameter;
multi.SaveAdd(myEncoderParameters);
}
private static ImageCodecInfo GetEncoderInfo(String mimeType)
{
int j;
ImageCodecInfo[] encoders;
encoders = ImageCodecInfo.GetImageEncoders();
for(j = 0; j < encoders.Length; ++j)
{
if(encoders[j].MimeType == mimeType)
return encoders[j];
}
return null;
}
}
