Add support for `png_set_compression_level`, to enable output of uncompressed PNG images #24

Closed nandhp closed 6 years ago

nandhp commented 6 years ago

In some circumstances (e.g. generating 30 video frames per second) it is useful to maximize encoding speed by outputting uncompressed PNGs. This is accomplished using the libpng function png_set_compression_level. Please consider adding support for this function.

I have incorporated this change into the following:

https://metacpan.org/release/BKB/Image-PNG-Libpng-0.44_01

Now you must (must) download and test that. You should also provide a test script that shows that it does what you want.
