    Hello Jon,

     

    I see both sides, but...

     

    Down sampling is always going to lose something, it's just whether it'll be noticeable for end use.

     

    With these things one would always start out with copies saved as... then once a certain APP & pic type proved itself as acceptable, one might assume that the future same methods would be mostly safe.

     

    I'm as close to deaf as possible, but all my Pink Floyd is saved as huge AIFFs, as I can tell the differences in most any compressed format... music from this millennia I'm happy to save as 2 bit MP0s.

    hi bd. thanks.

     

    i'm not following. i am talking about providing a specific warning to those users that may have files for which downsizing using these filters will result in trashed (i.e. all green) images in their PDF. this makes the document unusable. this was not an issue of noticeability as it totally trashed the pdf. I only caught this at the last minute after doing about 25 more PDF's and I haven't had the time to go back and finish all the rest of them. I'd like to but what are the parameters necessary to end up with a trashed pdf using this filter and/or one or another workflow.

     

    you are saying this is not necessary because an intelligent computer user would never save over the original (or delete the original and rename the downsampled pdf with the original name)?

     

    if this is the case it certainly does not seem like grounds for not having a warning about this bug (as it relates to this workflow with these filters) and I have a 1 TB HD and it is just not practical for me to keep /all/ the original pdf's since the whole reason for my needing to downsample them is that they are monstrously and inhumanly sized.

     

    also, i upload pdf to ftp and to my websites all the time and the amount of effort that will be required to re-load these them with some kind of "..._150 dpi.pdf" suffix is just not realistic. re-writing them over the original and simply re-uploading them to the ftp is however in most of my workflows...

     

    i mean, i am organizing pdf's ultimately to get them into software that organizes pdf's and keeping the original somewhere seems to me to be super impractical for anyone except a real graphic professional who works for a firm that has that sort of archival option IMO.

     

    regards.

    hi bd.

     

    yeah. i think a lot of people are going to be getting bit by this trashing of the images bug.

     

    i just scanned 8 images to TIFF using Preview at 2+/- MB per image and the pdf out of Preview is 20 MB. I have cases over here that are 100 MB. it is supposed to be a /Portable/ Document Format and there are 174 /thousand/ views of this thread.

     

    i really think there needs to be some kind of documentation as to when you can expect (as I found) that a document is trashed by the images all turning green. i mean. i am not a genius in this area but I am going to have to use this filter a /lot/ and it would be helpful to know what i need to check in order not to expect to trash my pdf.

     

    if it is not directly tied to the filters themselves, the use of the filter is caught up in it since using the filter could trash the document. maybe i am missing something in which case I would love to understand it better but i have definitely had a pdf get trashed using the filters while trying to downsize it.

    Oh yes, I think a warning is in order myself, especially now that there's so many people using computers that would be better off with a TV remote, & falling for the "it just works" thing, or that "Standards" are standardly interpretated & executed.

     

    People should be made aware that altering a file... uhhh, alters the file & likely should not be done unless you have a backup of the original, hence the suggestion to Save As... a new file... if the new one is OK, then you can git rid of the bigger one.

     

    Personally, other than it's hazy ubiquidessnous, I've never been impressed with PDFs, far too much bloat, only a Word Doc can surpass it in that respect, if you had PageStream on a Mac, PC, Atari, or Amiga, I could send you a PGS doc fron 25 years ago of say 50K that would be 10 times that if I sent the same as a PDF, only diff is the PGS would be far easier to do what you want with it!

    Thank you Jérôme for the links confirmation.

     

    While I see they worked for others, your filters (like others I downloaded) continue to make my pdfs larger.  So I am at a loss.

    Hi BD.

     

    I am not sure I am following you here but if there is a confirmed bug that irrevocably *trashes* pdf's due to some undocumented (?) circumstances it seems that it would be worthwhile to alert users who are downsampling their pdf's in a manner that can /also/ make this happen.

     

    After all, it is not like there are 174,000 viewers of this thread because pdf's are being handled seamlessly in Mac OS.

     

    I mean, it is one thing if we could post documentation to this thread that explains the circumstances that make this trashing of pdf's happen, but short of this I think it would be important to put together a more informal caution.

     

    Regards.

    Agreed, as I said, but where, how?

    OK. yes. got it. Thanks for the great help here and elsewhere.

     

    I dunno, I am not technically sophisticated enough to track this one down but I know it is a bona fide issue...and it is definitely something to watch out for if there isn't better documentation from Apple or elsewhere on it...

     

    cheers.

    I do not understand what I'm doing wrong, I have downloaded your filters, dropped them in my library folder, yet I still do not see an option to use your filters when I go to "save as" and click on the drop down quartz filter bar.  Someone please help me out :/

    Hello TeeGee

     

    Have you dropped the files into the \user\library\filters folder?

    Hi TeeGee.

     

    You shoulf put the unzipped folder, called "Filters" in your "Macintosh HD/Library/" folder. If there is already a Filters folder ther, just add to it the ocntent of the unzipped downloaded folder.

     

    Then, in Preview, you should select "Save As" and choosed PDF as a format. The filters should then be avialable.

     

    If you use OS X 10.7, just use "Export" instead of "Save As" and it is exactly the same.

     

    Please tell if this helped. If not, can you please tell which version of OS X you are using?

     

    Have a nice day,

     

    Jérôme.

    Hello momemor,

     

    I do not have a filters folder in my library.  I have added Jerome Colas' folder tiltled "filters 2"

    TeeGee117 Level 1 Level 1 (0 points)

    Hello Jerome,

     

    I have put the unzipped folder titled, "filters2" in my "macintos HD/Library/" folder.  I am running on a Mac OS X 10.6.8.

     

    Thank you both for trying to figure this out.

    Hi TeeGee. The folder should be named "Filters" with a capital F. Rename your "filters 2" folder to "Filters" and you should be good to go.

     

    Your downloaded folder has probably been named "Filters 2" because you already had a "Filters" folder. For example if you downloaded twice the same item.

    Here is a snapshot of how you actually save...

    You choose the settings in the Quartz FIlter
