Release Notes: The main code addition is limited support for literal PostScript specials using gs. For example, most of the PSTricks package can now be rendered using dvipng. Unfortunately, dvipng can only handle drawing PostScript code at the moment, not PostScript code intended to make dvips + gs scale, rotate, or move DVI glyphs (characters). This is because the graphics state cannot be communicated back to dvipng from gs. As a result, there are no guarantees. Also, the performance in terms of runtime could be better.
Release Notes: This release adds CJK (Chinese, Japanese, and Korean) support. More specifically, it adds support for the subfonts used in the CJK-latex package. TrueType fonts have been tested somewhat more, and the ttfonts.map file is now used, if present on the system. It also fixes a few bugs, most notably a version problem with Freetype < 2.1.8 and a graphics inclusion bug for non-.-paths.
Release Notes: The release adds the ability to include bitmapped images (PNG, JPEG, and GIF), and changes PostScript inclusion so that the image is not cropped to the bounding box (unless requested) and has a transparent background. For performance reasons, the output image is now true color if an image is included. The output quality is substantially improved when using the Freetype font library. A few bugs were fixed and the internal color cache for better performance was enhanced.
Release Notes: This release adds proper alpha channel support and xcolor support. It also reestablishes identification of preview-latex' tightpage mode option.
Release Notes: This release adds the ability to give a fallback color for the transparent border, and makes few other small changes.
Release Notes: This release adds GIF support if the drawing library, libgd, is new enough to support GIF writing. It also adds some command-line switches: --picky, --noghostscript, --nogssafer, --gif, and --gamma. A few portability issues have also been taken care of, as well as a bug in the color special support.
Release Notes: This release adds --depth and --height options for vertical positioning on Web pages. It also fixes some bugs, in particular one that would hang dvipng in certain PostScript font installations.
Release Notes: This release is mainly to provide documentation. It also introduces "drift", compensating for rounding errors along the lines described in 'dvitype'. Also, on systems with a fairly new gd (2.0.14 or newer), the PNG compression can be specified on the command line; the default is to opt for speed.
