Convert WMF to APNG (Animated PNG)

The Windows Metafile (WMF) is a graphic file format used by Microsoft Windows to store vector and bitmap image data. Originating in the late 1980s, WMF files enable the efficient exchange of graphical content between applications. They serve functions like clip art storage, image rendering in documents, and transferring graphics across different software platforms. Designed to be device-independent, WMF ensures consistent image presentation regardless of the output device, maintaining visual fidelity across varying screen resolutions and printer outputs. As a legacy format, its use has diminished with the advent of more advanced graphical file formats.

Animated Portable Network Graphics (APNG) is an extension of the Portable Network Graphics (PNG) format designed to support animated images. Introduced in 2004, APNG allows for animated sequences while retaining backward compatibility with non-animated PNG files. This format is utilized for its lossless compression, making it ideal for web graphics where image quality is paramount. APNG files are widely used for animated icons, logos, and other elements that benefit from high-quality animations without the artifacts common in GIF files. Its concise, efficient structure makes it a preferred choice among developers and designers focused on optimizing web performance.
