Convert SR2 to APNG (Animated PNG)

The SR2 file extension stands for "Sony RAW 2", a format used by Sony digital cameras to store uncompressed image data. Introduced in December 2005 with the Sony DSC-R1 model, SR2 files capture raw image data directly from the camera's sensor, preserving maximum detail and dynamic range for post-processing. This format is favored by professional photographers for its flexibility in editing and superior image quality compared to compressed formats. SR2 is part of Sony's suite of RAW formats, which also includes SRF and ARW.

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.
