f2102d906f Use the info structure to keep track of our memory block sizes to reduce duplicated code and cut down on errors. 2014-09-09 20:58:19 -07:00
969ff7c850 Make sure calculate_memory matches with the allocations. Fix some errant asserts. 2014-09-09 20:51:29 -07:00
8355ea1184 Use height, not width, for correct progress report. 2014-09-09 18:41:28 -07:00
4b69c0637e If alpha is zero then sneakily replace it with a very small nonzero so that the color data is preserved.
Pre-process n1 so that we don't have to do it later on. Can't do n0 since it's used to find the coefficient index.

d510d70b6a Report downsample progress by when we empty the ring buffer, it's more accurate that way. 2014-09-09 16:35:00 -07:00
084baed15c Replace premul test with better premul test that doesn't require visual inspection. 2014-09-09 16:30:06 -07:00

43fbc1d5e3 Rearrange the algebra on two of the filters to avoid repeating decimals which cause precision loss. Use int32 to test filters because it's more accurate. 2014-09-09 14:10:14 -07:00
ca241daefa Use rounding to try to preserve the original value. Fix test case. 2014-09-09 12:16:23 -07:00
145690788c Use input_h + pixel_margin * 2 to prevent progress report from ever going above 1. Always report a 0 before and a 1 at the end of each resize. 2014-09-09 10:58:01 -07:00
