Does DAZ Studio 4.6 support LZW compressed TIF files?

Greetings,
I'm asking because there's a significant amount of disk space taken up by Very Large Textures that are in apparently uncompressed TIFF form. If I could LZW compress them it would save me gigabytes of storage, easily.

I know this is a niche question, but it'd be really helpful to know!

    If you have photoshop or Gimp you could take the .tiff's and re-save as jpg. It's gonna be a pain to do it that way cause you'll have to reset up the diffuse and bump maps and re-save as a duf. Maybe someone else can think of an easier way but that's all I can think of atm.

    I can do the conversions to jpeg automatically if I wanted to (just a small shell script).

    The reason I wanted to leave them as TIFF files (i.e. not change the filename, just add a compression level to them) is that any existing DUF files which apply those textures will name them by their full name, including extension, and that'd just be WAY too much a PITA to find and fix existing .duf, .dsf, and who-knows-what-else.

    The other reason not to convert to JPEG is that JPEG is lossy, and while that rarely matters for the colors of clothing, it matters a LOT for normals and displacement. But the specifically-referenced-filename problem is an even bigger one, so that is a non-starter.

    The answer, though, is yes. I found a few TIFF files in the texture directory that are already LZW compressed. I have a command-line tool that will in-place compress TIFF files, so I think I'm going to go do that with any that I find that aren't. (For example Luthbelina's new outfit's displacement maps are uncompressed TIFF files.)

    I already do this with DSF files; if I find new DSF files in my library that aren't gzipped, I gzip them, delete the uncompressed versions, and rename the gzipped version to *.dsf again. Saves me dozens of gigs, which matters a lot on my laptop.

    That is a great idea, Morgan. What command line tool do you use to compress your TIFF files?

    It's named 'tiffutil' and I think it comes with Mac OS X, and I use it like this: 

    tiffutil -lzw Olympia_Face_NM.tif -out Olympia_Face_NM-c.tif
mv Olympia_Face_NM.tif raw-Olympia_Face_NM.tif
mv Olympia_Face_NM-c.tif Olympia_Face_NM.tif
    Mind you that's all scripted, so it's more like:
    tiffutil -lzw $1 -out tmp.tiff
mv $1 raw-$1
mv tmp.tiff $1

    Then I can either delete the raw-* files, or move them someplace safe (and off my local box) if I'm super concerned. (I'm not. I can always revert, restore, or re-install if I screw something up.)

    I'm fairly sure you could compile tiffutil for other platforms, but I couldn't give you details offhand...

    Thanks for the details. I use Windows 7, and so far (Google search) I haven't been able to find the same kind of tool. I hope someone can suggest one. Maybe I could create a Photoshop action to open the file and resave it with LZW compression.

    You can use TDLmake which is part of 3delight utilities. It is already included in DAZ bin directory. Manual is here http://www.3delight.com/en/uploads/docs/3delight/3delight_12.html

    As LZW is already active by default the conversion should be straightforword : tdlmake inputfile.tif outputfile.tif

    Otherwise you could use some free tools I guess. I do have the option to convert inside Xnview and there is also a batch conversion option in XnviewMP. See http://www.xnview.com/en/xnview/

    If you like command like you could also use ImageMagic http://www.imagemagick.org/script/command-line-options.php

    It would be easy to convert a whole directory also with command lines using "Forfiles" command on Windows
