PNG - Ideas to Integrated Circuits

PNG-supporting Image-Conversion Applications
● Take-1 [FileStream] (Win32) - version 2.0 and later; read/write; shareware. (This is a suite of
"web-publishing tools," including an image editor, a [lossy] image optimizer/compressor, and an
HTML editor.)
● Thingi - see PNGConv above
● ThumbNailer [Smaller Animals Software] (Win32) - version 2.0 and later; read/write; full alpha
support? claims full gamma support; background and text support; shareware.
● ThumbsPlus [Cerious Software] (Win32) - version 3.0 beta 3 and later; read/write as of version
3.0g; full alpha support as of version 7(?), but no interlacing or transparency support for writing
in version 3 (no info on intervening versions); text support; reportedly excellent compression,
aside from saving unused palette entries (e.g., 256 for a 64-color image--fixed in version 4.10);
broken conversion of GIF palettes in version 4.10 (example here); commercial (formerly
shareware). (This program also has the ability to make web pages of thumbnails. Windows 3.x
was supported in older versions, and a "final Macintosh beta" was available between 1998 and
2000, but as of 2005 there is no longer any trace of it.)
● tiff2png [Willem van Schaik, Greg Roelofs] (Unix, DOS, OS/2, Win32) - all versions; write-only;
full alpha support; gamma support; requires libtiff, libpng, zlib, and possibly libjpeg (depending
on the libtiff version); freeware with source. (This is the official TIFF-to-PNG converter. See also
ptot above.)
● tnailer [William Rhodes] (Perl) - all versions; read/write; requires PerlMagick, ImageMagick,
libpng and zlib; freeware (GPL) with source. (This is a command-line utility to create web pages
of thumbnails from image collections, such as from a digital camera. It can also convert sizes and
compression levels of larger images.)
● ToyViewer [Takeshi Ogihara] (Mac OS X, NeXTStep/OpenStep) - version 2.0(?) and later for
NeXTStep, and all versions for Mac OS X; read/write; partial transparency support; support for
writing text comments; freeware with source.
● Translator [John Kortink] (RISC OS) - version 8.0(?) and later; read/write; shareware. (See also
John's conversion-only Creator app above.)
● Turbo Browser [FileStream] (Win32) - version 7.2 and later; read/write; shareware. (This is a
file manager, similar to Windows Explorer, but with file-transfer, HTML-editing, image-viewing,
and image-conversion capabilities in addition to standard file-management functions. There is
also a simpler version called Turbo Browser Express.)
