Abstract
ClearType resolution recovery resampling of source content is performed as the source content is transformed from a source presentation format to a destination presentation format by at least distinguishing between pixels of a bitmap corresponding to the source content that are ClearType pixels and pixels of the same bitmap that are non-ClearType pixels. Identification of ClearType pixels is performed by identifying Alpha values of pixels that are less than 1, by identifying high frequency color fringing of pixels and/or by explicit declarations in the bitmap. The bitmap is resampled by applying transforms, such as convolution filters, in selective and discriminating ways, such that, for example, the ClearType pixels of the bitmap are resampled/transformed on a subpixel granularity and the non-ClearType pixels of the same bitmap are transformed on a pixel granularity.
