BitmapInfoHeader

BmpImage.BitmapInfoHeader property

Quickly access essential details about your bitmap image with this straightforward function. Perfect for developers needing to retrieve header information for their images.

public BitmapInfoHeader BitmapInfoHeader { get; }

Property Value

The bitmap information header.

Examples

The following example gets the information from the BMP header and prints it to the console.

[C#]

using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(@"c:\temp\sample.bmp"))
{
    Aspose.Imaging.FileFormats.Bmp.BmpImage bmpImage = (Aspose.Imaging.FileFormats.Bmp.BmpImage)image;
    Aspose.Imaging.FileFormats.Bmp.BitmapInfoHeader header = bmpImage.BitmapInfoHeader;

    System.Console.WriteLine("The number of palette colors that are required for displaying the bitmap: {0}", header.BitmapColorsImportant);
    System.Console.WriteLine("The number of palette colors used in the bitmap: {0}", header.BitmapColorsUsed);
    System.Console.WriteLine("The bitmap compression: {0}", header.BitmapCompression);
    System.Console.WriteLine("The bitmap height: {0}", header.BitmapHeight);
    System.Console.WriteLine("The bitmap width: {0}", header.BitmapWidth);
    System.Console.WriteLine("The bitmap raw data size in bytes: {0}", header.BitmapImageSize);
    System.Console.WriteLine("The number of planes: {0}", header.BitmapPlanes);
    System.Console.WriteLine("The horizontal resolution of the bitmap, in pixels-per-meter: {0}", header.BitmapXPelsPerMeter);
    System.Console.WriteLine("The vertical resolution of the bitmap, in pixels-per-meter: {0}", header.BitmapYPelsPerMeter);
    System.Console.WriteLine("The number of bits per pixel: {0}", header.BitsPerPixel);
    System.Console.WriteLine("The extra bits masks: {0}", header.ExtraBitMasks);
    System.Console.WriteLine("The header size in bytes: {0}", header.HeaderSize);
}

//The output may look like this:
//The number of palette colors that are required for displaying the bitmap: 0
//The number of palette colors used in the bitmap: 0
//The bitmap compression: 0
//The bitmap height: 375
//The bitmap width: 500
//The bitmap raw data size in bytes: 562500
//The number of planes: 1
//The horizontal resolution of the bitmap, in pixels-per-meter: 0
//The vertical resolution of the bitmap, in pixels-per-meter: 0
//The number of bits per pixel: 24
//The extra bits masks: 
//The header size in bytes: 40
