bc7de9b734 Add documentation to new public methods for optimizing in-memory. 2016-05-05 12:21:31 -04:00

2573b20966 Add support for optimizing PNGs loaded in-memory. 
In keeping with being able to use oxipng as a library, this adds a way
for developers to optimize a PNG already in memory, instead of requiring
  it to exist on disk first.

08eb44ec1a Partially implement --preserve 
Needs better implementation once stable Rust improves,
or perhaps see if there's a crate for this

Reference #4 but keep open

f3b8665278 Use miniz for compression strategies 0 and 1 
Worst case (RGB/A images) it performs similarly to zlib
Best case (Indexed images) it performs 1-2 orders of magnitude better

Zlib is kept for strategies 2 and 3, where it performs an order of
magnitude better than miniz

132a15403a Don't store intermediate copies of compressed image data unless it is current best. 
Reduces peak memory usage significantly.

87e21c2020 Limit number of simultaneous threads to help memory usage at high opt levels 
Still uses a lot of memory. Would like to remove the storage of all compression
data attempts and calculate the best immediately during each thread.
