In this post, I will show you how to convert BMP file to GIF in C#. The first step you must do is to create a
Bitmap
object. In this example, I passed filename to constructor of this object. Next you need to create
ImageCodecInfo
and choose the appropriate mime type of output format. You can set quality and compression of output image. In case you need to do this, you must create
EncoderParameters
object which represents list of
EncoderParameter
objects. This objects represent set of parameters which encoder uses for image encoding.
static void Main(string[] args)
{
Bitmap myBitmap=new Bitmap(@"test.bmp");
ImageCodecInfo myImageCodecInfo = GetEncoderInfo("image/gif"); ;
EncoderParameter encCompressionrParameter = new EncoderParameter(System.Drawing.Imaging.Encoder.Compression, (long)EncoderValue.CompressionLZW); ;
EncoderParameter encQualityParameter = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 0L);
EncoderParameters myEncoderParameters = new EncoderParameters(2);
myEncoderParameters.Param[0] = encCompressionrParameter;
myEncoderParameters.Param[1] = encQualityParameter;
myBitmap.Save("Output.gif", myImageCodecInfo, 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;
}
