| * Fix the bindTexture() filters on X11 to not rely on mipmap generation.Trond Kjernåsen2010-06-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | The default GL_TEXTURE_MIN_FILTER is GL_NEAREST_MIPMAP_LINEAR, which means you have to have mipmaps generated in order for it to produce correct results. We don't use mipmaps when this particular path is taken, so use texture filters that is in line with what we do in the non-pixmap_to_texture path. Task-number: QTBUG-11158 Reviewed-by: Kim
| * Fix antialiasing with transformed text in OpenGL2 paint engineEskil Abrahamsen Blomfeldt2010-05-313-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Updated: This also fixes a general issue where some combinations of font sizes and transformations will cause the engine to sample neighbouring glyphs, so this has been backported to Qt 4.6.x.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you have two non-sharing GL contexts and try to draw the same QPixmap in both of them, they will wind up competing for a spot in the texture cache.

* | | Speed up QStaticText with affine transformation on GL2 engineEskil Abrahamsen Blomfeldt2010-06-012-22/+14
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the OpenGL2 paint engine supports transforming the prerendered glyphs rather than rasterizing the glyphs with the transformation applied, we don't need to recalculate the QStaticText layout whenever the transformation changes. This means that we can do fast animated transforms for QStaticText on this paint engine. A quick test yields something like 100x speed-up on Windows. This also give visually better results, as we previously would animate the hinting of the glyphs, thus causing jittering. The autotest has been updated to reflect the fact that drawText() and drawStaticText() now go through identical paths on GL, also when transforms are set on the painter. However, the scale was changed in one test, because it was so great that drawText() would fall back to paths. With QStaticText the idea is speed, so you'll get a poor, but fast result instead, which is better than tricking people. Reviewed-by: Samuel

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When drawing text using glyphs, the shader manager will select the "MaskFragmentShader" which requires a varying called "textureCoords" which is used to sample the glyph from the glyph texture. That's fine, except when you try to use one of the pattern brushes or a texture brush, because the src pixel fragment shader snippets for those brushes also sample from a texture (the brush texture) and name the verying they use "textureCoords" too. This led to textureCoords being defined twice, which in turn caused a shader compile error which then casued the seg-fault. This patch simply renames the varying used to pass the coordinates for the brush texture so it doesn't conflict. Reviewed-By: Kim Task-Number: QTBUG-9522

| | | | | | | | | | | | | | | | | | | | | | | | | | | | It's better to defer the synchronisation to just before the point it is actually needed. When used as a window surface, this is in flush and scroll. If the QX11GLPixmapData is used as the defaut backend for QPixmaps, it might need to be put back into endPaint. However, the GL driver will hopefully make sure rendering to the pixmap is complete before binding it as a texture via texture-from-pixmap. Also, it's probably better to use eglWaitClient rather than glFinish for synchronisation as it is potentially slightly more optimal. Reviewed-By: TrustMe
