I'm having some trouble with TIF/TIFF's, and am wondering if anyone has had similar issues and addressed them, or if others are having no issue at all with such files and hopefully how your setup differs from mine.
My basic setup is:
Ubuntu 12.04 (64-bit)
PHP version: 5.3.10-1ubuntu3.2
Graphics support: PHP Imagick library 3.1.0RC1
ImageMagick 6.6.9-7 2012-08-17 Q16
'convert -list configure' shows TIFF under delegates
'identify -list format' shows TIFF as rw+, with libtiff version 3.9.5
class-WEBdocs is enabled but TIFF disabled (attempting various options, including disabling it entirely, doesn't fix the issue described below, just alters how the browser displays the issue)
Several other plugins are enabled, none of them 3rd party uploads, and no others appear to have anything to do with TIFF's; otherwise everything is "stock" Zenphoto.
TIF/TIFF files and thumbnails appear to work with other programs, such as 'digikam' and 'image viewer'.
However, when I place a TIF/TIFF in a Zenphoto directory and attempt to view, issues begin. First, Zenphoto does not recognize any file with only a TIF extension (perhaps this is related to imagick?). Renaming to a TIFF extension leads to Zenphoto recognizing the file and even pulling metadata from it, a workaround I could certainly live with - but that brings me to the second issue, which is not generating a usable/used thumbnail.
By that I mean in album view I see only the filename or caption text as a link, instead of a thumbnail -- there's not even a placeholder box, just text, which is very jumbled if it's trying to show a long caption. But upon looking in the relevant cache folder, there is in fact a generated file -- <filename>_100_w100_h100_thumb.tiff. Sometimes that file can be opened (directly from the cache folder) and appears to be a perfectly good thumb sized image of the original, but sometimes that file appears to be black or blank ('image viewer' properties show it to be a 100x100 image, but otherwise the image appears to view as just a black box). In either case, it is not shown as a thumb in Zenphoto, just the text link. Clicking on the text opens the image viewing page, however with class-WEBdocs/TIFF disabled there is no image, just the filename or caption as a link to the full image. Clicking on the full image link will load the full image.
I've used TIFF's from a few different sources, although not in much volume. All of them have been around 12MB or less, so not huge files, but I'd really rather not have to add another step by converting the ones I have -- especially when this seems so close to working. The ones with black box thumbnails only seem to all have been generated by Silverfast (scanning software), and I might blame that except those same images work fine in other programs. The generated thumbs from other TIFF's I can view in something like 'image viewer', but still aren't being shown in Zenphoto for some reason.
So that's a long way of saying, does anyone have an idea why this isn't working or what I might try to address it?
