* Fixed floating point overflow issues in QRasterizer::rasterizeLineSamuel Rødal2010-09-231-1/+0
| | | | | | | | | | | | | | | | | Change 7c673a4cf64ba04 introduced some autotest failures in the fpe_steepSlopes test in QPainter. Since the other rasterizers all deal in a 26.6 fixed point coordinate space we should snap the line vertices to this to prevent floating point overflows due to very steep slopes. This also necessitates keeping track of four different slope / inverse slope increments for each of the four edges. This also fixes a previously QEXPECT_FAIL'ed test case.

* Fixed scaled point drawing with square cap in raster paint engine.Samuel Rødal2010-09-231-0/+22
| | | | | | | | | | | With a large pen width and a small scale, due to the hacky way we draw points (stroking a line from (x, y) to (x + tiny_amount, y)), we some times end up snapping these two points to the same in rasterizeLine(). If we instead apply the SquareCap before we do clipping / snapping we don't get this problem. Task-number: QTBUG-13429 Reviewed-by: Trond
* Revert "Fix the rendering of lines with the X11 paint engine"Samuel Rødal2010-08-181-65/+0
| | | | | | | | | | | | | | | | This reverts commit ebbab30af417dfbf3df47dec15c0e2f8d6a30fa6, which broke fill / outline consistency, and when trying to fix that by rounding the fill the same way that broke rendering in Creator. Unfortunately the X11 paint engine is too sensitive to changes, there have already been tons of patches to make it as consistent as possible. It's simply not possible to get the same rounding for both fill and outlines and at the same time have consistency between fill and outline (no holes or fill outside the outline), while using the integer based Xlib rendering API. Hopefully in 4.8 we'll switch to raster and the X11 paint engine will be a legacy. Reviewed-by: Trond

| | | | | | | | | | | | | | | | | | | | | | | | | | Since the width is multiplied into the dash, it needs to be divided out, otherwise you can get a dashOffset which is greater than the pattern at the index, and the dash can become negative. This will in turn lead to passing a negative width to the rasterizer, which at some point will get cast to an unsigned int and overflow. Depending on the position of the line and size of the buffer, this will either crash or produce garbled output. Task-number: QT-4444 Reviewed-by: Samuel
