* FreeType: fix garbled bitmap glyphs.Gravatar agl@chromium.org2009-08-11
| | | | | | | | | | | | | At some point (probably in one of the LCD patches), the fMaskFormat for bitmap glyphs changed from kA8 to kBW. Formerly, bitmap glyphs were always transformed into A8 format. With this patch, we check the fMaskFormat and pick the correct transform at run time. http://code.google.com/p/chromium/issues/detail?id=18531 http://codereview.appspot.com/104071 git-svn-id: http://skia.googlecode.com/svn/trunk@313 2bbb7eff-a529-9590-31e7-b0007b416f81
* Remove assertion in getAddrLCD.Gravatar agl@chromium.org2009-08-11
| | | | | | | | | | | Because the underlying mask extends a pixel to the left and right (or top and bottom on vertical LCDs), the requested pixel can actaully be one pixel outside the bounds, thus this assertion is incorrect. http://codereview.appspot.com/105077 git-svn-id: http://skia.googlecode.com/svn/trunk@312 2bbb7eff-a529-9590-31e7-b0007b416f81

* Add runtime detection for missing subpixel support in FreeType.Gravatar agl@chromium.org2009-07-28
| | | | | | | | | | | | | | | | | | | r291 added support for building on platforms where subpixel support has been compiled out of FreeType. However, it turns out that there is a common situation in which we build on platforms with subpixel support, but have to run without it: people downloading Chromium from the buildbots. Because we this, we need a runtime solution. Modifying the conversion routines for this seems suboptimal because the extra branches will slow down everyone. So we probe subpixel support at runtime by trying to install a low-pass filter. If we fail at this, then we map all the SkScalerContext::Rec structures to remove subpixel mode. http://codereview.appspot.com/98057 git-svn-id: http://skia.googlecode.com/svn/trunk@293 2bbb7eff-a529-9590-31e7-b0007b416f81

* Support subpixel text when FreeType is built without such support.Gravatar agl@chromium.org2009-07-28
| | | | | | | | | | | | | | | | On Fedora, at least, FreeType is built without subpixel support. It tries to simulate subpixel mode by replicating the gray-values three times. However, it fails to simulate the actions of the low-pass filter and so doesn't add border around the glyphs. This patch adds a compile-time constant, which is the number of bytes of filter border. If this value is zero (because FreeType is simulating subpixel support), then we add a transparent border ourselves when transforming from FreeType rendered glyphs to masks. http://codereview.appspot.com/96171 git-svn-id: http://skia.googlecode.com/svn/trunk@291 2bbb7eff-a529-9590-31e7-b0007b416f81

* Fix valgrind warnings triggered in vertical mode.Gravatar agl@chromium.org2009-07-22
| | | | | | | | | | | | | | | | | | | Now that Chrome is rendering subpixel text, I was able to try running the renderer process under valgrind, which turned up a number of issues. First, I was calculating the stride of vertical LCD glyphs wrong (typo). Secondly, I was going horribly wrong when a glyph was being blitted at the edge of a bitmap. I suspected something was wrong with the code, but I wasn't clear enough with the structure of the code when writing it to figure out what the correct solution was. http://codereview.appspot.com/97059 git-svn-id: http://skia.googlecode.com/svn/trunk@284 2bbb7eff-a529-9590-31e7-b0007b416f81

* Subpixel glyph rendering support.Gravatar agl@chromium.org2009-07-21
| | | | | | | | | | | | | | | | This patch adds support for rendering subpixel glyphs (using Freetype). In order to control this rendering see SkPaint::setLCDRenderText in SkPaint.h. To setup the LCD mode, see SkFontHost::SetSubpixelOrientation and SkFontHost::SetSubpixelOrder in SkFontHost.h. This patch also adds more fine grained control over hinting (again, only for Freetype currently). One can now control the hinting with SkPaint::setHinting. git-svn-id: http://skia.googlecode.com/svn/trunk@275 2bbb7eff-a529-9590-31e7-b0007b416f81
