Release Notes: Econvert now has a command line option to draw vector text and select the foreground and background color for text and vector drawing, including human readable name presets. The ditherizers now support multiple channels, e.g. dithering RGB or RGBA images (as opposed to just 8 bit gray data), and were optimized for speed. The font handling code was refactored.
Release Notes: The new image iterator and codegen was implemented for RGBA (RGB + Alpha) image data. The RAW camera file support was vastly improved by updating the 2 year old bundled dcraw copy as well as surrounding C++ glue code. Support for extracting the thumbnails of RAW files was implemented. The TIFF codec was improved to not to try to decode RAW images written as defective TIFF files.
Release Notes: Lossless and faster JPEG cropping now takes residual crops into account, left over from 8x8 JPEG DCT blocks. The PDF writer was fixed to write floating point numbers in a well defined format (fixes JPEG writing on Debian and similar patched C library variants). The install targets were improved to make sure the directories exist before copying the files, as well as take DESTDIR into account in all places.
Release Notes: Dynamic range normalization was reimplemented using the new image iterator to support all bit-depths as well as increased speed. The empty-page detection again internally uses the black and white optimization for more consistent results, and the threshold for black and white images can now be specified during colorspace conversion via the external SWIG wrapped API.
Release Notes: Hocr2pdf was improved to allow the extraction of the plain text while parsing the HOCR input. Compilation without any image codec installed on the system was fixed, and a Mac OS X linker bug worked around.
Release Notes: The new PDF writer was improved to write PDF files with fewer text objects and thus not crash Adobe Acrobat 7 and older versions. Some typos in the human-readable output, including help text, were fixed.
Release Notes: The PDF codec was completely rewritten to not only allow you to dump images into PDFs, but write arbitrary vector objects and multiple pages. A new command line tool was added that allows hOCR annotated HTML to be converted into perfectly laid out, searchable PDF files. The barcode recognition was improved regarding CODE25 and CODE28 recognition and checksum computation. De-skew accuracy was slightly improved and is now exported through SWIG.
Release Notes: A keybinding was added to the lightweight image viewer edisplay to invert images. The GIF codec was fixed to correctly read larger data chunks as requested by libungif. The RGB to RGBA conversion buffer use was fixed. The GRAY8 thresholding was optimized.
Release Notes: Support for circle and ellipse elements was added to the SVG parser. Vector font rendering was cleaned up and optimized and the font on path rendering fixed to use the actual foreground color. A image canvas resize function was exported via the external SWIG API. A possible buffer overrun when parsing numeric values was fixed in the SVG parser.
Release Notes: Support was added to control the barcode scan directions through the externally available SWIG interface for Perl, Python, PHP, and Lua. The contouring and segmentation examples were updated to compile with the current core library, resorted, and extended. The Python configure test was improved to also cover the slightly older Python version 2.4.
