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

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

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

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

aee30095c7 refactor internal interfaces to avoid passing things multiple times; 
finish prepping 'stbir__info' even before calculate_memory;
get rid of 'noinfo' functions since now calculate_memory doesn't need 'em;
add new binary-searched sRGB function (untested)
