* NPOT texture support in QOpenGLTextureCacheCedric Chedaleux2014-02-041-1/+28
| | | | | | | | | Enable non power of two texture support for non compatible NPOT GPU. If the context does not handle NPOTTexture feature, the image to bind is scaled to POT size. It works with OpenGL ES and Desktop version. It is actually almost the same code as the one in QGLContextPrivate::bindTexture.

* Do not byteswap RGBA8888 formatsAllan Sandfeld Jensen2013-10-251-28/+2
| | | | | | | | | | | | | The three RGBA8888 formats was introduced to make it possible to have QImages and QPixmaps in native OpenGL formats, but uploaded textures of these types are still converted to ARGB first and then swapped back. This patch detects the formats and ensures the unneeded back-and-forth conversion does not take place. It also replaces a seemingly unused private API meant for the same goal.

* QOpenGLTextureCache : make it possible to skip qgl_byteSwapImageElvis Lee2013-01-251-2/+5
| | | | | | | | | | Improving performance when making texture from QImage, this commit makes it possible to skip qgl_byteSwapImage. If gl_FragColor of fragment shader is properly configured, qgl_byteSwapImage is not required. Ex) gl_FragColor = texture2D(texture, textureCoord).bgra; Change-Id: If1f2d7dc1fc1c4e583cc3f38dec95a9d29417cd2 Reviewed-by: Samuel Rødal <samuel.rodal@digia.com>

* Expose QPA API under qpa/*Girish Ramakrishnan2012-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main reasons for doing this are: 1. _qpa.h end up in the master QtGui include file. QtGui is meant for userland applications. qpa code is neither binary nor source compatible. Inadvertant use of QPA api makes the user code binary-incompatible. 2. syncqt creates forwarding headers for non-private header files. This gives people the impression that this is public API. As discussed on the mailing list, even though QPA api is internal and subject to change, it needs to treated differently from private headers since they will be used by in-qtbase and out-of-qtbase plugins. This commit does the following: 1. The _qpa in QPA header files is dropped. 2. syncqt now treats any file with qplatform prefix as a special file and moves it to qpa/ directory. The recommended way of using QPA API in plugins is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API from multiple modules (for example, qplatformfoo might be in QtPrintSupport) 3. The user needs to explicitly add QT += <module>-private to get access to the qpa api. 4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo includes. This commit does not change the cpp filenames. This requires a more careful merging of existing non qpa cpp files and existing cpp files on a case by case basis. This can be done at anytime. The following files are not renamed as part of this changed but will be fixed as part of a future change: src/gui/kernel/qgenericpluginfactory_qpa.h src/gui/kernel/qgenericplugin_qpa.h src/gui/kernel/qwindowsysteminterface_qpa.h files were renamed using for x in `find . -name "qplatform*_qpa.h"`; do git mv $x "${x/_qpa.h/.h}"; done for x in `find . -name "qplatform*_qpa_p.h"`; do git mv $x "${x/_qpa_p.h/_p.h}"; done includes were renamed using script for file in `find . -name "*.h" -or -name "*.cpp" -or -name "*.mm"`; do sed -i -e 's,.*#.*include.*<\(Qt.*/\)\?\(QPlatform.*\)>,#include <qpa/\L\2.h>,g' \ -e 's,.*#.*include.*"\(Qt.*/\)\?\(QPlatform.*\)",#include <qpa/\L\2.h>,g' \ -e 's,.*#.*include.* "\(qplatform.*\)_qpa.h",#include <qpa/\L\1.h>,g' \ -e 's,.*#.*include.*"\(qplatform.*\)_qpa_p.h",#include <qpa/\L\1_p.h>,g' \ -e 's,.*#.*include.*<\(Qt.*/\|Qt.*/private/\|private/\)\?\(qplatform.*\)_qpa\(.*\)>,#include <qpa/\2\3>,g' \ -e 's,.*#.*include.*"\(Qt.*/\|Qt.*/private/\|private/\)\?\(qplatform.*\)_qpa\(.*\)",#include <qpa/\2\3>,g' \ $file done Change-Id: I04a350314a45746e3911f54b3b21ad03315afb67 Reviewed-by: Morten Johan Sørvig <morten.sorvig@nokia.com> Reviewed-by: Samuel Rødal <samuel.rodal@nokia.com> Reviewed-by: Friedemann Kleint <Friedemann.Kleint@nokia.com> Reviewed-by: Sean Harmer <sean.harmer@kdab.com> Reviewed-by: Lars Knoll <lars.knoll@nokia.com> Reviewed-by: Gunnar Sletta <gunnar.sletta@nokia.com>
