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.
