Minor gift to new contributors. Makes methods intention more obvious.

2020-08-29Splash bilinear scaling: Don't try read behind endTobias Deimigner1-1/+1
Source line iteration in Splash::scaleImageYuXuBilinear already tries to prevent a read behind source image end, as the comment indicates it and as it's conceptually reasonable. But the check for (currentSrcRow < srcHeight) is wrong and doesn't do what it claims. currentSrcRow will only ever increase to srcHeight - 1 after scaledHeight iterations. Therefore the check always evaluates to true, and src() is aways called. Intention was to prevented the line fetch for the last run and leave line2 identical to line1 (the "extra padding"). Nothing bad happened, because SplashOutputDev::imageSrc and alphaImageSrc gracefully handle the behind-end read. Should be corrected either.

2020-04-21[splash, arthur] Use stroking opacity when clipping to a stroke pathOliver Sander2-4/+10
When filling a region that is clipped to a stroke path, then the stroking opacity shall be used rather than the fill opacity. I couldn't find this in the spec, but it seems to be what Acrobat does. BUG:

2020-02-27Implement Splash::gouraudTriangleShadedFill for non parametrized shadingsAlbert Astals Cid3-74/+211
Fixes #881 Unfortunately only implemented for shadings where the 3 vertices of the triangle have the same color for now since i got lost trying to implement the coloring (and also have no pdf to check against) The reason this fixes #881 is because if Splash::gouraudTriangleShadedFill returns false because it doesn't natively support this shading, the default rendering algorithm of kicks in, and that rendering what does is render different triangles without them knowing they belong to the same shading, meaning that if you have some opacity the edges of the triangles will overlap and and up having different color than the one you really wanted

2019-07-21SplashXPathScanner: Optionally use small_vector from boostStefan Brüns2-0/+16
Currently, each row in the intersections vector is allocated separately, when the first intersection is added. To avoid these allocations for common simple polygons, boost::container::small_vector<4, T> is used, which stores up to 4 intersections inline. small_vector is a header-only class. For the documents from #57 (fdo#96728) and #24 (fdo#78728), the runtime/memory is significantly reduced (according to /usr/bin/time -v): (1) $> pdftoppm -r 18 -aa no runsforever-poppler.pdf (2) $> pdftoppm surf-types.pdf Before/After runsforever-poppler | surf-types User time (seconds): 2348.08 / 1773.53 | 7.76 / 5.02 Maximum resident set size (kbytes): 46288 / 45896 | 14076 / 13748

2019-03-21Remove method GooList::getOliver Sander2-2/+2
Use operator[] instead. This is another move towards discarding GooList in favor of std::vector.
