Examples

The following example shows how to extract information about raw data format and alpha channel from a BMP image.

[C#]

// Create a 32-bpp BMP image of 100 x 100 px.
using (Aspose.Imaging.FileFormats.Bmp.BmpImage bmpImage = new Aspose.Imaging.FileFormats.Bmp.BmpImage(100, 100, 32, null))
{
    System.Console.WriteLine("FileFormat={0}, RawDataFormat={1}, HasAlpha={2}", bmpImage.FileFormat, bmpImage.RawDataFormat, bmpImage.HasAlpha);
};

// Create a 24-bpp BMP image of 100 x 100 px.
using (Aspose.Imaging.FileFormats.Bmp.BmpImage bmpImage = new Aspose.Imaging.FileFormats.Bmp.BmpImage(100, 100, 24, null))
{
    System.Console.WriteLine("FileFormat={0}, RawDataFormat={1}, HasAlpha={2}", bmpImage.FileFormat, bmpImage.RawDataFormat, bmpImage.HasAlpha);
};

// Generally, BMP doesn't support alpha channel so the output will look like this:
// FileFormat = Bmp, RawDataFormat = Rgb32Bpp, used channels: 8,8,8,8, HasAlpha = False
// FileFormat = Bmp, RawDataFormat = Rgb24Bpp, used channels: 8,8,8, HasAlpha = False
