Jorge Rodriguez 6922628106 Use an even smaller epsilon. Allow the user to avoid the epsilon business if they want to preserve their alpha values. 2014-09-10 15:03:55 -07:00

stb_textedit: Add support for alternative keyboard shortcuts for text/line start/end.
 2014-09-10 11:02:04 -07:00
Fabian Giesen 40cc1c59b2 Add support for alternative keyboard shortcuts for text/line start/end. 2014-09-10 10:54:22 -07:00
Jorge Rodriguez c9d67446d2 Reverse allocation routines parameter order so that the context is at the back. 2014-09-09 22:57:15 -07:00
Jorge Rodriguez 17b931047c Add the epsilon value into the alpha instead of using an if statement. It's a tiny bit faster and it can be removed afterwards. 2014-09-09 22:47:53 -07:00
Jorge Rodriguez 1d5c902e2e These minor optimizations were probably already done by the compiler but they can't hurt. 2014-09-09 22:07:40 -07:00
Jorge Rodriguez 41e6aad693 Avoid repeated adds and ensure correct round-trip result. 2014-09-09 21:57:46 -07:00
Jorge Rodriguez 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
Jorge Rodriguez 969ff7c850 Make sure calculate_memory matches with the allocations. Fix some errant asserts. 2014-09-09 20:51:29 -07:00
Jorge Rodriguez 8355ea1184 Use height, not width, for correct progress report. 2014-09-09 18:41:28 -07:00
Jorge Rodriguez 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.

Jorge Rodriguez 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
Jorge Rodriguez 084baed15c Replace premul test with better premul test that doesn't require visual inspection. 2014-09-09 16:30:06 -07:00
Jorge Rodriguez 497eab8339 Normalize downsample coefficients. 2014-09-09 15:22:29 -07:00
Jorge Rodriguez 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
Jorge Rodriguez ca241daefa Use rounding to try to preserve the original value. Fix test case. 2014-09-09 12:16:23 -07:00
Jorge Rodriguez 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
