OpenGL ES2 doesn't support NPOT textures in combination with GL_REPEAT, so for OpenGL ES2 we use a custom program that emulates repeat by taking the fractional part of the texture coordinates. This is not enough though, as merely setting GL_TEXTURE_WRAP_x to GL_REPEAT with a NPOT texture is an error in some implementations, so we have to guard the call to updateTextureFilter() in updateBrushTexture() with a check for OpenGL ES2 and use GL_CLAMP_TO_EDGE instead.

Platforms other than Windows (including WinRT) are not affected. The existing Angle and desktop configurations are not affected. These continue to function as before and Angle remains the default. In the future, when all modules have added support for the dynamic path, as described below, the default configuration could be changed to be the dynamic one. This would allow providing a single set of binaries in the official builds instead of the current two. When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are never defined. Instead, the code path that has traditionally been desktop GL only becomes the dynamic path that has to do runtime checks. Qt modules and applications are not linked to opengl32.dll or libegl/glesv2.dll in this case. Instead, QtGui exports all necessary egl/egl/gl functions which will, under the hood, forward all requests to a dynamically loaded EGL/WGL/GL implementation. Porting guide (better said, changes needed to prepare your code to work with dynamic GL builds when the fallback to Angle is utilized): 1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to differentiate between desktop and ES where needed. Keep in mind that it is the desktop GL header (plus qopenglext.h) that is included, not the GLES one. QtGui's proxy will handle some differences, for example calling glClearDepth will route to glClearDepthf when needed. The built-in eglGetProcAddress is able to retrieve pointers for standard GLES2 functions too so code resolving OpenGL 2 functions will function in any case. 2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds, but never "angle" or "opengles2". 3. The preprocessor define QT_OPENGL_DYNAMIC is also available in dynamic builds. The usage of this is strongly discouraged and should not be needed anywhere except for QtGui and the platform plugin. 4. Code in need of the library handle can use QOpenGLFunctions::platformGLHandle(). The decision on which library to load is currently based on a simple test that creates a dummy window/context and tries to resolve an OpenGL 2 function. If this fails, it goes for Angle. This seems to work well on Win7 PCs for example that do not have proper graphics drivers providing OpenGL installed but are D3D9 capable using the default drivers. Setting QT_OPENGL to desktop or angle skips the test and forces usage of the given GL. There are also two new application attributes that could be used for the same purpose. If Angle is requested but the libraries are not present, desktop is tried. If desktop is requested, or if angle is requested but nothing works, the EGL/WGL functions will still be callable but will return 0. This conveniently means that eglInitialize() and such will report a failure. Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will tell which implementation is chosen. The textures example application is ported to OpenGL 2, the GL 1 code path is removed. [ChangeLog][QtGui] Qt builds on Windows can now be configured for dynamic loading of the OpenGL implementation. This can be requested by passing -opengl dynamic to configure. In this mode no modules will link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will dynamically choose between desktop and Angle during the first GL/EGL/WGL call. This allows deploying applications with a single set of Qt libraries with the ability of transparently falling back to Angle in case the opengl32.dll is not suitable, due to missing graphics drivers for example.

* Restore smooth-scaled drawing of 0.5x-2.0x scaled glyphs in the GL engineTor Arne Vestbø2013-07-081-12/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b5922c89ba942 (Add support for retina glyph-based text drawing in the GL engine), and commit 155a20628b91 (Use QPaintEngineEx to decide if font is too big for using the glyph cache) together changed the behavior of drawing scaled cached glyphs in the GL engine, producing blocky text drawing when using the FreeType font engine. Whereas before we would cache all glyphs without any transform, and let the paint engine take care of the transform, commit b5922c added support for a scaled GL glyph cache, resulting in a 2x cache, drawn at 1x for example. The problem was that the FreeType engine claimed to support producing glyphs at 2x, but did that using the QFontEngine baseclass implementations, which use a simple fast-transform to scale up the glyphs. The result was a 2x cache with horrible looking glyphs. The first step in fixing this issue was to have the FreeType engine claim to only support translations. This would then make the paint engine choose path-based drawing for all scaled text, which is slow. To restore the optimization that we would draw 0.5x-2.0x scaled text using a smooth-scale in the GL engine (which was removed in 155a206), we then needed to extend shouldDrawCachedGlyphs() and add a special condition for this, coupled with a bit of logic in drawCachedGlyphs() that ensures we don't propagate the painter scale to the glyph cache if the engine is not able to produce scaled glyphs for it. This means we get the old behavior of the GL engine doing a smooth scale of the 1x glyph in the cache. Finally, since the raster engine also checks if the font engine supports the current transform, but for FreeType then ends up in a separate code path when actually drawing the glyphs (as the FreeType font engine supports internal glyph caching), we need to add a corresponding check for hasInternalCaching() in the shouldDrawCachedGlyphs() function, now that the FreeType engine only reports that it supports translations.

* | Refactor paint/font-engine shouldDrawCachedGlyphs and supportsTransformationsTor Arne Vestbø2013-01-101-10/+12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cruft had built up over time, and this is an attempt at cleaning up the naming and use of these functions, and should not have any behavioral effects. The function supportsTransformations() has been renamed in QPaintEngineEx to reflect its use, which is to decide if QPainter needs to pre-transform the coordinates of the static text before asking the paint-engine to draw it. The new name is requiresPretransformedGlyphPositions(). The OpenGL and CoreGraphics (Mac) paint engines keep their behavior of not needing pre-transformed text, while the raster engine needs this when using cached glyphs. The base-class implementation assumes that all transforms that include a projection will need pre-transform, which is also the case for the raster engine. All decisions in the paint engines about whether or not to use the glyph cache when drawing text are now deferred to the function shouldDrawCachedGlyphs(), which has been refactored for the GL paint engine(s) to share more logic. All implementations call the base class implementation, which ensures that large font sizes will not be cached. The raster engine will in addition ask the font engine whether or not it can produce glyphs for the glyph-cache with the given transform. This is the only remaining instance of the supportsTransformations() function, and will for all font engines except the CoreText engine support affine transformations. The CoreText engine on the other hand only supports translations (for now).

* OpenGL: Use official glext.h and gl2ext.h headersSean Harmer2012-08-201-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Khronos group makes the glext.h (Desktop OpenGL) and gl2ext.h (OpenGL ES2) headers officially available nowadays. Most (all?) Linux systems ship this by default. On Windows platforms the glext.h file needs to be downloaded from http://www.opengl.org/registry/api/glext.h and placed alongside the system OpenGL header. Making use of the official header reduces the maintenance overhead for OpenGL support in Qt by removing the need to copy and paste definitions into the Qt sources. As the Khronos-provided headers are standardised and backwards and forwards compatible we can utilise these for all platforms rather than just for Windows. This means that all definitions required by Qt will be present even if the system ships out-dated equivalents. Mac OS X needs special handling in that we should always use the system-provided headers there. This is because Apple controls the OpenGL driver and the headers that go along with it. As such there is no possibility that the driver exposes additional functionality compared with the system-provided OpenGL headers. Apple has also decided to make different decisions about some OpenGL typedefs compared to other implementations. For example, Apple typdefs GLhandleARB to void* whereas other platforms use unsigned int. The alternative, which is to use the system provided glext.h (or gl2ext.h) header means that Qt code would need to check for the availability of such definitions wherever it is not guaranteed to be provided by core OpenGL/ES just to compile. The proposed approach means that Qt can compile regardless of the system's OpenGL extension support. We just need to be rigourous in runtime checking of support for extensions but that is already a requirement (and is missing in a few places, see TODO's added in this commit). The official Khronos headers are added to Qt as qopenglext.h - Desktop OpenGL qopengles2ext.h - OpenGL ES2 They need to be public but not part of QtGui module include, hence the headers have been modified by adding #if 0 #pragma qt_no_master_include #endif to them. This has been tested on: Gentoo Linux with GCC 4.6.3 Windows 7 with MSVC 2010 Mac OSX 10.8 with Apple clang 4.0 (based on LLVM 3.1svn) QNX with qcc (based on GCC 4.4) A small change is needed to QtDeclarative when building for OpenGL ES 2 after applying this commit.

* Move glyphMargin() to QFontEngineJiang Jiang2012-01-241-7/+8
| | | | | | | | | | | | | glyphMargin() support for QTextureGlyphCache is implemented in respective font engines, thus this function is platform dependent. Before Qt 5 the code is guarded in macros like #ifdef Q_WS_MAC, now we should move them into QFontEngine and its subclasses. So far only Windows font engines support it. FreeType and Core Text based font engines all ignore it. Change-Id: Ia14016533d8fbfaacf848a7d3bc928f8197318f5 Reviewed-by: Eskil Abrahamsen Blomfeldt <eskil.abrahamsen-blomfeldt@nokia.com>

* Fixed crash in GL 2 paint engine on Intel Atom.Samuel Rødal2012-01-171-3/+7
| | | | | | | | | | | The GPU in question supports GL 2 but not framebuffer objects. Since we anyway have a font rendering path that doesn't use FBOs we might as well not require framebuffer objects in order to use the GL 2 engine.

* Remove all non-inline of qMalloc/qFree/qRealloc.Robin Burchell2012-01-061-9/+9
| | | | | | | | | | | | We're trying to deprecate these, so don't use them anymore. The inline uses of these have been left intact, for the moment. Inline code will need to create their own non-inline allocation methods (for future-proofing to allow alterations in how e.g. individual containers allocate) Change-Id: I1071a487c25e95b7bb81a3327b20c5481fb5ed22 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com> Reviewed-by: Bradley T.

* Fix subpixel positioning supportJiang Jiang2011-11-081-1/+1
| | | | | | | | | | | | Move subpixelPositionForX from QTextureGlyphCache to QFontEngine, since some font engines like QFontEngineFT may need a custom implementation or tweak it a little bit. In QRasterPaintEngine::drawCachedGlyphs, do not add aliasedCoodinate to x offset as that will break subpixel positioning.

* Get rid of legacy glTexParameterf calls.Samuel Rødal2011-10-281-10/+10
| | | | | | | | | | | ES 1.0 didn't have glTexParameteri, which is why we sometimes used glTexParameterf. However, we shouldn't use glTexParameterf because that's treating integer values as floating point, which is not type safe. ES 1.1+ and ES 2.x have glTexParameteri, and we don't really care about supporting ES 1.0 in any case in Qt 5. Change-Id: I6b586b31ddc418ba319c4cc88f6bb3978fdbd040 Reviewed-by: Kim M.
