Proposal to Replace Deflate with Zstandard or LZ4 for Faster .PNG Processing
By
marklit
Solid neighbourhood-bakery energy. Trustworthy and warm.
Summary
The article discusses the slow read/write times of .PNG files and proposes the adoption of newer, faster lossless open-source codecs like Zstandard (maintained by Facebook) and LZ4. These codecs, which are free from patent concerns, could significantly improve processing speeds for users handling large volumes of .PNG files. Zstandard is already being used in the Khronos KTX2 GPU texture format specification.
Key quotes
· 3 pulledOne of the issues we have with .PNG is slow read/write times.
Zstandard is used by the new Khronos KTX2 GPU texture format specification.
The possible speedups are quite significant, and for users that read and write a lot of .PNG's as part of their data processing pipelines the speedups will be high value improvements.
