* 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
