Examples
The following example shows how to read PNG file in a strict mode. The strict mode allows to find potential problems in PNG images, e.g. unrecognized data blocks, unexpected end of file. Such files still can be opened in default (non-strict) mode by Aspose.Imaging and by common viewers as well. However any attempts to open them in the strict mode cause a corresponding exception.
string dir = "c:\\aspose.imaging\\issues\\net\\3635\\testdata\\3565";
string inputFileName = System.IO.Path.Combine(dir, "FC5F1998104EB92469CB14070628073616BB28F9.png");
string outputFileName = inputFileName + ".png";
// Default mode (non-strict) - successul reading.
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFileName))
{
image.Save(outputFileName, new Aspose.Imaging.ImageOptions.PngOptions());
}
// Strict mode - ImageLoadException : Unexpected end of file.
using (Aspose.Imaging.Image image = Aspose.Imaging.Image.Load(inputFileName, new Aspose.Imaging.ImageLoadOptions.PngLoadOptions() { StrictMode = true }))
{
image.Save(outputFileName, new Aspose.Imaging.ImageOptions.PngOptions());
