All releases of Potrace
Release Notes: A DXF backend was added. The output is in the drawing interchange format used by computer aided design software. The Gimppath backend was changed to be compatible with current versions of GIMP. The EPS, PDF, and SVG backends now use high-resolution bounding boxes. The default scaling of the EPS, PDF, and SVG backends is now fixed at 72dpi. A new option --flat was added to the SVG backend. A new option --tight was added to remove whitespace around the input image before calculating its scaling and placement.
Release Notes: The xfig and eps backends were improved, and a fixed pagesize PDF backend was added. Support for BMP version 4 and version 5 files, as well as top-down BMP files, was added. Minor speed improvements were made to Potrace and major speed improvements were made to mkbitmap. A Gaussian blur option was added to mkbitmap. Libtool is now used to build and optionally install the Potrace library. An optional simplified progress bar was added for dumb terminals. This release also contains some portability improvements, cross-compilation improvements, and minor bug fixes.
Release Notes: This release contains minor bugfixes and portability improvements. Rotation is now implemented in the PDF backend.
Release Notes: This is a bugfix release. A bug in the progress bar code, which caused arithmetic exceptions on some 64-bit architectures, has been fixed.
Release Notes: This release is 20-60% faster than the previous release. A new PDF backend was added. An option to display a progress bar was added. Some spurious "premature end of file" messages were eliminated. The core functionality was separated into a library with a documented API, making it easier for developers to incorporate potrace into other software.
Release Notes: A bug was fixed which caused potrace to "hang" on large input files. Some bugs in the compression code were also fixed. The presence of the "compress" program is now determined at run-time, rather than compile-time, to allow pre-compiled versions to work anywhere.
Release Notes: This is primarily a bugfix release. A bug which caused potrace to crash when applied to an empty (all white) bitmap was fixed. The options -2 and -3 are now ignored when unsupported, rather than causing an error. The bounding box in the xfig backend was fixed, and the PostScript output now has better page encapsulation. Bitmaps of dimension 0 are now tolerated better. There were improvements to the test suite, autoconfiguration, and portability.
Release Notes: This release includes backends for gimp and xfig. A separate program, mkbitmap, was added for turning greyscale or color images into high-quality input to potrace. Two new options were added, --opaque and -- group, to give greater flexibility in generating editable PostScript and SVG output. The bitmap decomposition algorithm now runs better on 64-bit platforms. Portability and autoconfiguration were vastly improved, and a test suite was added. Runlength encoded BMP files can now be read.
Release Notes: An SVG (scalable vector graphics) backend was added. PGM, PPM, and BMP file formats are now supported A speed improvement of up to 3.3 on some large files was achieved. New --blacklevel and --invert options were added to control how color images are converted to bitmaps. Autoconfiguration and error messages were improved.
