Tutorial: Extract Image Info with the CodecsImageInfo Class

Like people, images are all different. Even though some images may look the same, there can be hidden information within the properties that make them unique. Perhaps you find yourself currently in a workspace that is going paperless and need a way to convert image files to the same format, size, or bits-per-pixel. You’ll first need to be able to quickly check the various image properties to see which ones already match your needs and which ones don’t.

LEADTOOLS offers developers an easy way to extract this image information with the CodecsImageInfo Class. This class provides methods to get information about images. There are hundreds of different image properties that can obtained with this class.

The essential code can be found below, but be sure to check out the full step-by-step tutorial to Extract Image Info. This will show you how to create a Windows Console application in C# that utilizes the CodecsImageInfo Class to get information from the various image formats supported by LEADTOOLS.

using (RasterCodecs codecs = new RasterCodecs()) 
	CodecsImageInfo info = codecs.GetInformation(fileName, true);
	string inputFileName = Path.GetFileNameWithoutExtension(fileName);
	string codecsInfoString = ($"Image Format: {info.Format}\n" +
		$"Information for: {inputFileName}\n" +
		$"BitsPerPixel: {info.BitsPerPixel}\n" +
		$"BytesPerLine: {info.BytesPerLine}\n" +
		$"ColorSpace: {info.ColorSpace}\n" +
		$"Byte Order: {info.Order}\n" +
		$"Image Height: {info.Height}\n" +
		$"Image Width: {info.Width}\n" +
		$"Image X Resolution: {info.XResolution}\n" +
		$"Image Y Resolution: {info.YResolution}\n" +
		$"Compression: {info.Compression}\n" +
		$"Page Number: {info.PageNumber}\n" +
		$"Total Pages: {info.TotalPages}");
