libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate baseline JPEG compression and decompression on x86, x86-64, Arm, PowerPC, and MIPS systems, as well as progressive JPEG compression on x86, x86-64, and Arm systems.

See the examples below. It should be noted that each image of this decoder needs to consume image width x image height x 3
bytes of RAM, and it needs to be combined with the overview_image_caching
feature to ensure that the memory usage is within a reasonable range.
