GifEncoderOptions Class

Syntax

Public NotInheritable Class GifEncoderOptions _
	Inherits EncoderOptions

public sealed class GifEncoderOptions : EncoderOptions

Remarks

This class enables to initialize both entire GIF file and separate frames settings. Usually you can use this class from Saving event handler to modify both global and frames settings. If you set global settings for the same file multiple times, only settings specified at the first time are used.

This table gives the explanation for all GIF settings:

MediaFormat property of this class always returns value that equals to GifFormat static field of the FormatManager class. Left and Top are used to specify offset of the frame relatively top left corner of the GIF.

Examples

Let's assume that we want to load a JPEG file and save this image as a web-optimized GIF file (for example, reduce number of colors to 32). This code sample demonstrates how to do it:

Dim bitmap As New Aurigma.GraphicsMill.Bitmap("c:\Mountain.jpg")

bitmap.ColorManagement.PaletteEntryCount = 32
bitmap.ColorManagement.ConvertToIndexed(8, Aurigma.GraphicsMill.ColorPaletteType.Adaptive, _
    Nothing)

bitmap.Save("C:\Mountain.gif", _
    New Aurigma.GraphicsMill.Codecs.GifEncoderOptions)

bitmap.Dispose()

using (Aurigma.GraphicsMill.Bitmap bitmap = 
           new Aurigma.GraphicsMill.Bitmap(@"c:\Mountain.jpg"))
{
    bitmap.ColorManagement.PaletteEntryCount = 32;
    bitmap.ColorManagement.ConvertToIndexed(8, Aurigma.GraphicsMill.ColorPaletteType.Adaptive, 
        null);

    bitmap.Save(@"C:\Mountain.gif", 
        new Aurigma.GraphicsMill.Codecs.GifEncoderOptions());
}
