* Fix textdrawing under GL on N900.Gunnar Sletta2010-05-071-1/+1
| | | | | | | | | | | | | | | | The driver in the N900 doesn't support glCopyTexSubImage or glReadPixels for FBO's that have a GL_ALPHA or POT color attachment. The ifdef'ed code in resize() was a previous attempt to make this work which didn't. We could have changed the texture to be GL_RGBA and changed the texture size to be NPOT, but that would have wasted precious GPU memory and would have been slower, so we waste a bit of system memory instead, by having a QImage copy along with the texture.

* Fix antialiasing with transformed text in OpenGL2 paint engineEskil Abrahamsen Blomfeldt2010-04-121-0/+1
| | | | | | | | | | | | | | Since the paint engine now transforms the prerendered glyphs instead of rendering transformed glyphs as paths, we need to turn on texture filtering to avoid antialiasing artifacts. In order to do this, we also need to pad the glyphs in the glyph cache, otherwise you will get artifacts when sampling the area around the glyph's bounding rect (where there might be other glyphs.) This done by adding a glyphPadding() function to the cache which returns the number of pixels to pad between each glyph. Task-number: QTBUG-9706 Reviewed-by: Tom
* Fix painting artifacts on textEskil Abrahamsen Blomfeldt2010-04-061-1/+2
| | | | | | | | | | | | | | The height of the row is not only decided by the maximum height of the set of glyphs currently being added to the glyph cache, but also the height of the glyphs previously added to the current line in the glyph cache. To minimize the space used, we now calculate the maximum height for glyphs per line, and use this as the vertical advancement when positioning the next line in the cache. The change also removes a redundant test ((c_x + c.w > c.h) is caught earlier on and will always be false at this point.) Task-number: QTBUG-9176 Reviewed-by: Trond

* Support transformations in drawStaticText() and optimize for spaceEskil Abrahamsen Blomfeldt2010-01-141-3/+2
| | | | | | | | | | 1. Support transformations on the painter in drawStaticText(). Transforming the painter will cause the text layout to be recalculated, except for translations, which are handled by shifting the position of the text items. 2. Make const length arrays of the internal data in QStaticTextItem in order to minimize the memory consumption.
* Optimize QStaticText for spaceEskil Abrahamsen Blomfeldt2010-01-141-3/+4
| | | | | | | | | | | By caching the results of getGlyphPositions() we can make a code path in the critical paint engines which is optimal both in space and speed. The engines where speed is of less importance (pdf engine etc.) which may need more information, we choose the slower code path of drawText() which lays out the text again. We should have optimal paths in raster, vg and GL2 paint engines. The others are less important. Memory consumption of static text is now 14 bytes per glyph, 8 bytes per item and a static overhead of 40 bytes per QStaticText object.
