stitching function monotonic detection<br> +<br> + Bug #699528 "A rare edge condition can cause a function to incorrectly signal a rangecheck error"<br> +<br> + This is rather difficult to describe. The problem occurs when we try to<br> + check for monotonicity of a stitching function between two data points<br> + of the parametric variable.<br> +<br> + We actually calculate a series of points between the two values and<br> + check to see that they all increase (or decrease). However, a stitching<br> + function can contain multiple functions, and so we break the range of<br> + values into groups at the limits of each function and check each<br> + group of values.<br> +<br> + If the lower value of the parameteric variable is 'close' to the upper<br> + bound of the current function, we decide to 'punt' it up to the next<br> + function, presumably to avoid the overhead of a miniscule break. That is<br> + we simply don't bother calculating tiny amounts at the end of a function<br> + we just do the next function.<br> +<br> + However, if the upper range of the parametric variable happened also<br> + to lie close to (but less than) the upper bound of the function, then<br> + when we used it to evaluate the next function in the array, it would lie<br> + below the bottom bound of that function, resulting in a rangecheck error.<br> +<br> + This commit applies two fixes; firstly, if the upper and lower values<br> + of the parametric variable are the same then this is a point, and there<br> + is no point in checking it, so just jump straight out.<br> +<br> + Secondly, the upper value is now promoted to the lower bound of the<br> + current function if it is less than that. This prevents us trying to<br> + use an out of bound value, in case we should somehow get both an upper<br> + *and* a lower bound which lie within the 'noise' threshold.<br> +<br> + Because the range of 'noise' is so small (the bounds values of the<br> + function divided by 1 million) there is no practical likelihood of<br> + us missing a function which is not monotonic between those data<br> + points.<br> +<br> +base/gsfunc3.c<br> +<p> +</blockquote> +<hr> +<p><strong>2015-03-19 11:33:51 +0000 +</strong> +<br>Tim Waugh <twaugh@redhat.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=00c14a25c0f0d5e5e65d2d489045e566ccf436df">00c14a25c0f0d5e5e65d2d489045e566ccf436df</a> +<blockquote> +<p> + bug #695876: check that page margins don't overlap in cups driver.<br> +<br> +cups/gdevcups.c<br> +<p> +</blockquote> +<hr> +<p><strong>2018-07-10 09:51:37 +0100 +</strong> +<br>Ken Sharp <ken.sharp@artifex.com><br> +<a href="http://git.ghostscript.com/?p=ghostpdl.git;a=commitdiff;h=87cfc860ea49a4a39c1198b419a019ed598416f0">87cfc860ea49a4a39c1198b419a019ed598416f0</a> +<blockquote> +<p> + PDF interpreter improve handling of PageLabels as pdfmark<br> +<br> + Patch supplied by Leon Bottou, see Bug #696568.
