fpng is a very fast C++ .PNG image reader/writer for 24/32bpp images. It's a single source file with no dependencies on any other library. fpng.cpp was written to see just how fast you can write .PNG's without sacrificing too much compression.
Franklin Products custom designs, manufactures, and distributes industrial process filtration products for a broad range of applications in many markets. A complete line of products to help you cost-effectively satisfy all of your filtration requirements from a single source.
fpng_py is available via pypi, with pre-build wheels for macOS and Windows with SSE enabled. There are no pre-build wheels for Linux, as they would require building without SSE, which would decrease the performance by a fair bit.
6. Filter Algorithms This chapter describes the filter algorithms that can be applied before compression. The purpose of these filters is to prepare the image data for optimum compression.
The fpng library provides C++ developers with a powerful and flexible tool for processing PNG images. Through the in-depth discussion and rich code examples in this article, we can see the application potential of the fpng library in image processing, game development, and cross-platform development.

Very fast .PNG image (24/32bpp) writer for Python. Compared to typical PNG libraries, its compression is about 10-20x faster, while producing 10-50% larger files. py-fpng-nb is a Python wrapper of fpng. If installation fails, upgrade pip with python -m pip install --upgrade pip and try again.
Fixed bug in fpng_get_info_internal () that could cause it to fail on malformed headers.
Hi Rich, (I sent an email about this issue, but I guess it didn't reach you) fpng is really efficient and interesting work. Congratulations ! However, to cover most of png usual features (and according my need), I think it would be great...
