Tutorial: Split a Multipage Image File Into Separate Files

In a previous post, we shared a tutorial on how to create a multipage file from multiple images. However, sometimes developers are looking to split a multipage file into separate files instead. In an office workspace, there is always something that needs to be printed and signed. Whether it’s for approving an idea, or for legal purposes, these documents are usually more than one page long. The signer will not want to print out every page of the document just to sign one page, that would only be a waste of time and paper. Splitting the document up will give you the one page that needs to be signed. Splitting files apart can easily be done when using the RasterCodecs Save Method within the LEADTOOLS Imaging libraries.

All that needs to be done to split a multipage file is first, get the total number of pages, and second, loop through each page and save it to one of many LEADTOOLS supported file formats. The code below will show you the core code on how to make the split. Or refer to our complete step-by-step tutorial on how to Split a Multipage Image File Into Separate Files.

// Split a Multipage Image into Single Files
using (RasterCodecs codecs = new RasterCodecs())
{
	int totalPages = codecs.GetTotalPages(inputFile);
	for (int page = 1; page <= totalPages; page++)
	{
		string outputFile = $@"C:\Users\Public\Documents\LEADTOOLS Images\
		{System.IO.Path.GetFileNameWithoutExtension(inputFile)}_page{page}.png";
		using (RasterImage image = codecs.Load(inputFile, page))
			codecs.Save(image, outputFile, RasterImageFormat.Png, 0);
	}
}
