Convert SRF to APNG (Animated PNG)

The SRF (Sony Raw File) is a RAW image file format used by Sony digital cameras, such as the DSC-F828 model, to store uncompressed, unaltered images captured by the camera's sensor. Introduced in January 2004, SRF files preserve high-quality image data, offering photographers greater flexibility in post-processing compared to compressed formats like JPEG. Over time, Sony developed subsequent formats like SR2 and ARW to enhance features and compression methods.

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.
