README

This is an extension for Tk800.014 and upper which supplies TIFF format loader for Photo image type. The TIFF code is stolen from imgTIFF.c from the img1.2b2 distribution by Jan Nijtmans. Use Tk-TIFF-0.01 for a Tk40*.* version.

Installation

You need libtiff (http://www.libtiff.org/ or ftp://ftp.sgi.com/graphics/tiff/) and probably libjpeg (ftp://ftp.uu.net/graphics/jpeg/) installed on your system.

Check Makefile.PL for configuration variables at the top and appropriate library and include paths. Then build the extension by typing:

        perl Makefile.PL
        make
        make test
        make install

The current version of the module is only tested with the following configurations:

• Linux 2.4.20 (RedHat 8.0), perl 5.8.0, Tk 800.025, tiff 3.5.7, jpeg ?
• Linux 2.4.20 (RedHat 8.0), perl 5.8.7, Tk 804.027, tiff 3.5.7, jpeg ?
• FreeBSD 4.10, perl 5.8.0, Tk 800.024, tiff 3.5.7, jpeg 6b
• FreeBSD 4.10, perl 5.8.3, Tk 804.027, tiff 3.5.7, jpeg 6b

Previous versions worked with other Linux and FreeBSD configurations. I expect that there are no more endian problems, so this module will also work on Sun Sparcs and other machines.

For AIX, I got reports that you have to manually add -lm and -lgcc to the @libs variable in Makefile.PL.

Since version 0.10, also 32-bit Float-TIFFs are supported, but only with Tk804.xxx and newer.
