* Some optimizations to the GL pixmap data.Samuel Rødal2010-09-091-5/+35

* Fix y-inverted pixmaps properly.Gunnar Sletta2010-01-221-9/+5
| | | | | | | | | | | | There is a lot of code depending on that pixmaps are flipped upside down in the gl graphicssystem, so toggling this requires extensive testing. Since we're anyway questioning the relevance of this feature (compared to raster + GL viewport) its simply not worth the effort to fix it properly right now. Revert "Fixed y-inverted pixmaps on N900." This reverts commit 57473d5d2a7bd6ae3117f61ff29264a1b790bb01.
* Fixed y-inverted pixmaps on N900.Gunnar Sletta2010-01-191-4/+8
| | | | | | | | | | | The QGLPixmapData used default bind options, which means that the pixmap is always flipped up-side-down and rendered with flipping. The opaque pixmaps were uploaded unflipped which caused the bug. Ideally we do not want pixmap flipping so change the default in gl pixmaps and tag it accordingly. Reviewed-by: Samuel

* Compressed texture binding for QtOpenGL: ETC1 and PVRTCRhys Weatherley2009-12-061-0/+57
| | | | | | | | | | | | | | | | The QGLContext::bindTexture(QString) function has been augmented with support for ETC1, PVRTC2, and PVRTC4 compressed textures, in addition to the existing DDS support. The QGLPixmapData class has also been modified to recognize compressed texture formats in fromFile() and fromData(). This change also fixes a bug in bindTexture() that prevented the same compressed texture file from being bound in multiple contexts. There is now a separate file cache for each context group.

* | | Use texture_from_pixmap on X11 & avoid copiesTom Cooksey2009-07-221-20/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch tries to use texture_from_pixmap extentions on glX to properly bind an X Pixmap to a texture in QGLContextPrivate::bindTexture(QPixmap,). Because GL & X have different coordinate systems, the pixmap will be inverted about the y-axis. The extension does however allow a GLX_Y_INVERTED_EXT attribute to be set which will bind the pixmap the correct way up. If the underlying driver doesn't support this, texture_from_pixmap can't be used for QGLContext::bindTexture, because that function expects the resulting texture to be the right way up. However, it can still be used internally by the paint engine for drawPixmap operations. For these cases, if the pixmap is inverted, the paint engine can simply invert the texture coords to compensate. This is why this patch also moves QGLTexture into qgl_p.h. QGLContextPrivate::bindTexture(QPixmap,) now returns a QGLTexture which the paint engine can inspect to see if it needs to invert the texture coords. Finally, it seems on some (probably all) drivers, deleting an X pixmap which has been bound to a texture before calling glFinish/swapBuffers renders garbage. Presumably this is because X deletes the pixmap behind the driver's back before it's had a chance to use it. To fix this, we reference all QPixmaps which have been bound to stop them being deleted and only deref them after we swap the buffer, when they can be safely deleted. Reviewed-By: Kim

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change moves the w, h, d variables to QPixmapData and introduces is_null to keep track of nullness. This is possible only because QPixmapData is internal API; otherwise we'd have to be smarter. The optimization makes the QPixmap::width() function take 7 instructions, down from 34 before. For the calculator demo in the declarative ui branch this reduces a block of 750000 instructions (out of 30000000) to around 100000-150000 instructions. Tested on Windows, Linux, Mac.
