marscandybar Posted July 21, 2016 Share Posted July 21, 2016 When I save as TIF, lanczos 3 (non separable), the resulting file is blank, or black, or filled with static. This is the file compression recommended in your tutorials (excellent, btw). Other filetypes, jpg, png are viewable with that compression algorithm. The resulting file is the same size as that calculated in the export pane. No Mac app I have can open, including graphic converter. Is this issue repeatable by members of this forum, or is it some anomaly related to my system? Quote Link to comment Share on other sites More sharing options...
mac_heibu Posted July 21, 2016 Share Posted July 21, 2016 Do you really save it? By changing the extension? Or do you export it, as you should do? Quote Link to comment Share on other sites More sharing options...
marscandybar Posted July 21, 2016 Author Share Posted July 21, 2016 I am exporting. Is this repeatable in your system? - have you tested this with the recommended compression and generated a tif that is viewable? I am not sure if this is an anomaly on my system or simply a bug.

CartoonMike Posted July 21, 2016 Share Posted July 21, 2016 As part of my workflow, I export lettered comic pages from AD as a TIFF file to import into Clip Studio Paint. Use the default settings. Have had no problems.

Staff MattP Posted July 21, 2016 Staff Share Posted July 21, 2016 Your document isn't CMYK by any chance is it? You can test if the TIFF is valid by simply opening that TIFF back into Affinity - if it opens then it's valid :) If you want to be completely sure, send one of the TIFFs you've made over to us at support@seriflabs.com and we'll take a look and see if there's anything strange about it.

marscandybar Posted July 21, 2016 Author Share Posted July 21, 2016 hey matt, Thanks for your responses, all. TIF file does open in affinity photo - but that's all. I have to be able to access these files with any/most mac graphics program. This file is RGB 16 BIT. I'll send support a drop box link to one of the files in question. I'd like to get their feedback. In the interim I've tried a number of variations: every single attempt works but the one I want. I can change the size and export and file is viewable. I can take a selection and paste it into a new doc and TIF export works. FWIW, on another forum, a commenter noted that TIF works best without compression. TIF is a venerable image archiving format; compressing can balloon file size to no good effect, said the commenter. BTW, the commenter wrote a book on filetypes - he's a reliable source. AP does not offer a no compression/resampling option...? So this becomes a feature request/bug fix - no resampling option. Quote Link to comment Share on other sites More sharing options...
