Hi everybody.
Though squeak.org says there is a TIFF files support in Squeak I can't find any signs of it. So, could someone point me to the actual TIFF files reading/writing library for Squeak/Pharo? Thanks. |

Thanks, Marcus.
I saw this page, but actually I expected to see a pure Smalltalk solution or at least an integrated plugin. Especially considering what official squeak site says about that (but why it is so? maybe tiff support was there before and was removed for some reasons?). It seems that the mentioned work of John M McIntosh is the only implementation of TIFF support. So I tried to build the plugin on linux. Results seem promising but I need help. The plugin works quite fine, all tests pass except four of them. Failures are caused by "isByteSwapped" which returns true on my linux machine, while I think it supposed to return false on Mac (is it true?). And I think this is somehow related to another bug I've faced. I mean colours mismatch, which I failed to fix. I'll try to build the plugin on windows to see if this behaviour is really platform related. But I would appreciate any help. The modified Smalltalk sources can be found at http://www.squeaksource.com/gherolyants. See packages TIFF-Kernel, TIFF-Tests and VMConstruction-Plugins-Tiff. The modified C sources can be found at http://github.com/gherolyants/tiff-plugin. 2010/8/17 Marcus Denker <[hidden email]>: > > On Aug 17, 2010, at 8:09 PM, George Herolyants wrote: > >> Hi everybody. >> >> Though squeak.org says there is a TIFF files support in Squeak I can't >> find any signs of it. >> So, could someone point me to the actual TIFF files reading/writing >> library for Squeak/Pharo? >> > > http://www.smalltalkconsulting.com/html/TIFFsource.html > > ? > > -- > Marcus Denker -- http://www.marcusdenker.de > INRIA Lille -- Nord Europe.

I think old PowerPC Macs were big-endian and the new Intel Macs are little-endian. The method must be checking the OS or something like that and getting the endian nature wrong.
