* Fixed missing text when using static text items in GL 2 engine.Samuel Rødal2011-02-023-5/+14
| | | | | | | | | | | | | | | When the context is destroyed and recreated, we end up with a new glyph cache, but we only recreate the vertex arrays for the very first static text item. We need to keep track of the glyph cache in each text item, so that we can recreate the vertex arrays and re-populate the cache accordingly. As the pointer might be the same after the glyph cache is recreated, we need to use serial numbers instead. We also need to re-create the cache when the context pointer has been invalidated, so that the static text items also get invalidated, and the texture glyph cache gets repopulated.

Commit edbc656b changed Q_DECL_IMPORT_IMPORT to Q_CORE_EXPORT when declaring QtCore functions in svg. Now we change Q_DECL_IMPORT to Q_GUI_EXPORT when declaring QtGui functions into opengl and openvg. Also removed the redundant keyword "extern" from the function declarations.

| * Fix regression in text rendering in OpenGL2 engineEskil Abrahamsen Blomfeldt2011-01-051-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Change 532115bcaa370af827a5cbad017b272842c5aacf introduced a regression by fixing a typo in the QT_OPENGL_ES_2 macro. This caused a broken and untested code path to be used in the GLES2 case. Since the QImage scanlines are 32 bit aligned, QImage::width() cannot be used when copying the data. Rather than pass in bytesPerLine() to the GL function, I opted to revert to the proven behavior, where the pad bytes are never read by GL but each scanline is copied separately, to avoid further regressions on different hardware. This also seems like the more correct approach, as the pad bytes should ideally not be copied into the cache texture. Reviewed-by: Samuel

* | Add work around for bug when painting w/glTexSubImage into large textureEskil Abrahamsen Blomfeldt2010-12-164-1/+8
|/ | | | | | | | | | | | | | It seems that copying small rectangles from glTexSubImage2D into a texture which is 2048x2048 is busted on some SGX drivers, even though the driver reports 2048 as the maximum texture size. This caused text to turn into flickering garbage once the texture glyph cache had grown to its max size (e.g. when painting very many Chinese glyphs.) To work around the problem, we hardcore the maximum texture height to 1024 on this driver so that the texture glyph cache is reset whenever that size is exceeded.

* Missing glyphs in GL when scaling QStaticText and QML text itemsEskil Abrahamsen Blomfeldt2010-12-101-5/+13
| | | | | | | | | | | | | Since scaled text is backed by an A8 glyph cache, it needs to repopulate even if it has previously populated the cache for the unscaled text. This means that we need to record in the userData that the type of the cache is not the same as the last time. Otherwise the A8 version of the cache will only be updated when it's created and when the text actually changes, leading to glyphs missing on screen when zooming text using a scale.

* Fix text disappearing on GL when RGB-path is taken (no transformation)Eskil Abrahamsen Blomfeldt2010-12-071-8/+11
| | | | | | | | | | | | | When there is no transformation on a glyph in the GL texture glyph cache, it will take the RGB code path to support subpixel antialiasing. In this code path we would ask glTextImage2D() to convert from a GL_ALPHA buffer to an internal format of GL_RGBA. This is not supported on OpenGL ES 2, and would cause missing text for some drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the OpenGL glyph cache filled up (the max texture size on the hardware was exceeded) the characters would be drawn as black blocks instead. As a work-around for this, the cache will now be cleared and repopulated whenever this happens, meaning that once in a while (when a lot of different glyphs have been drawn in a font) there will be a performance hit. A more complete solution is described in QTBUG-13784, but this requires so much refactoring that it was deemed too risky for a patch release. This patch fixes the problem with a small penalty and low risk. Task-number: QT-3971 Reviewed-by: Samuel

|/ | | | | | | | | | | | | | | If you create/destroy gl contexts a lot, you may sometimes get a new context with the same pointer as a destroyed context. When you look up the glyph cache in the font engine using the context pointer as a key, you will then get a glyph cache which contains no valid data. We need to reset the glyph cache completely in this case and set up bindings for the new context so that the glyph cache can be repopulated and reused. Note that there is a different solution for this in Qt 4.8, so this is temporary solution for the Qt 4.7.x series. Task-number: QT-4162 Reviewed-by: Fabien Freling
