What is CMX file format?

CMX (Corel Metafile Exchange) is a vector graphics file format developed by Corel to store illustrations, drawings, graphs, and logos. It is commonly used for exporting and importing vector graphics between graphical software applications. CMX files store information such as line widths, colors, gradients, and text. The data is usually stored in a compressed format, allowing for smaller file sizes. CMX is a format that is still widely used by graphic designers and illustrators, as many older applications are not compatible with modern formats. In comparison to more modern formats such as SVG, CMX files do not support more advanced features, such as using alpha channels. However, CMX files can be easily converted to other formats, making them an excellent choice for projects needing a large variety of compatibility.
