    How to Crop EMF Image using Shifts or Rectangle Approaches in .NET Applications

    This technical tip explains how .NET developers can Crop an EMF Image inside their .NET applications. Image cropping usually refers to the removal of the outer parts of an image to help improve the framing. Cropping may also be used to cut out some portion of an image to increase the focus on a particular area. Aspose.Imaging for .Net API supports
