fixed : custom Quartz-filters are not available system-wide

Question :

In the past, I used to create my own custom Quartz-filters in ColorSync Utility, and they were instantly available system-wide in MacOSX. Now, in OSX 10.8 Mountain Lion and OSX 10.9 Mavericks, I don’t have access to my Quartz-filters anymore…

What is wrong ? And how can I fix this ?

Answer :

In the latest versions of OSX, there seems to be a bug preventing OSX to find Quartz-filters stored outside of the ‘official’ “Filters”-folder that is inside the “Library”-folder in the “System”-folder… so, since all custom-made Quartz-filters are stored inside the “Filters”-folder that is inside the (invisible) “Library”-folder in the User’s “Home”-folder, your custom-made Quartz-filters are not found by OSX…

The solution is to just move them into the right (official) “Filters”-folder. (Yep, it’s that easy…)

For an in-depth step-by-step guide for doing so, follow the procedure outlined here.

fixed : Reduce File Size makes PDF unreadable

Question :

I have created a PDF of 4 pages in the Preview app, but I can’t eMail it to anyone because it turns out to be a 39MB file…

I know the probable cause, because some of the pages are entire A4-size pictures scanned as JPEG at 300dpi…

So I tried to use various ways of saving (or exporting) as PDF from within Preview, but they all end up with the same oversized 39MB file… except for one : the “Reduced File Size” filter from the “Export” option gives me a 240kB file that turns out to be completely unreadable…

Isn’t there any simple way to get a readable PDF of about 5MB or so ?

 

Answer :

Yes there is, but unfortunately it’s rather tricky to set up at first (since there is still no option in Preview, nor in “Save as PDF”, to adjust the PDF-output on the fly… and on top of that : there is a bug in the latest versions of OSX that prevents self-made Quartz-filters from ColorSync Utility to be accessible throughout OSX…)

Here’s how to :

1- open the ColorSync Utility that is in the Utilities folder within the Applications folder

2- if no window opens, click on File –> New Window

3- then click on the “Filters” tab

4- then click on the “+”-button in the bottom-left corner to create a new Quartz-filter

5- type “Reduce File Size 75dpi”, then click on the small round button (with the small white triangle in it) at the end of the line

6- from the pulldown menu select “Add Image Effects Component > Color Image Sampling” and now some adjusting options appear, leave most of them as-is, only at “Resolution:” type “75 pixels/inch” (so leave the other options empty and leave “Quality:” at “High”)

7- repeat this last step, but this time select “Add Image Effects Component > Grey Image Sampling” from the pulldown menu (so set “Resolution:” to “75 pixels/inch” here also)

8- tripple-check to make sure that the name of the Quartz-filter is “Reduce File Size 75dpi” and the “Resolution:” is set to “75 dpi/inch” at both instances… if that’s not the case : correct it before continuing (just retype at the correct spot)

OPTIONAL : click on the “+”-button again to create another new Quartz-filter, call it “Reduce File Size 120dpi” and repeat the above procedure, just set “Resolution:” to “120 dpi/inch” this time (…and you can even repeat this for other resolutions like 100 dpi/inch)

9- now close ColorSync Utility

10- now, in the Finder, press the ALT-key on your keyboard and select “Go” from the upper menu bar, in the pulldown and extra (ghost) folder called “Library” will appear, click on it and in the Finder window that opens, select the “Filters” folder (there you will see the Quartz-filters you’ve just created in ColorSync Utility)

11- then, in the Finder open another (new) Finder window and open the (regular) “Filters” folder that is in the “Library” folder in the “System” folder also (there you will see all the standard Quartz-filters available throughout OSX)

12- put both of these Finder windows side-by-side, then select the Quartz-filter files you’ve custom created, and drag them into the other “Library” folder (the one in the “System” folder)

13- then you get an authentication warning message that you need administrator rights to add anything into the folder, so type your administrator password and the custom Quartz-filter files will be moved into the System’s “Filters” folder

UPDATE : from OSX 10.11 El_Capitan on, you will see a grey NoEntry-sign when trying to access the System’s “Filters” folder ; this is due to El-Capitan’s SIP (System Integrity Protection) feature ; to solve this follow these extra steps :

  • instead of moving your self-made Quartz-filters into the ~/System/Library/Filters folder, you should move them to the ~/Library/Filters folder
  • since that last folder doesn’t exist by default, you will have to create it first
  • to do so, go to ~/Library in a Finder-window and click on the Sprocket-icon (a.k.a. GearWheel-icon) and select “New Folder” from the pulldown list
  • when prompted, enter you administrator’s name & password to allow this new folder to be created
  • when done, move your self-made Quartz-filters info this newly created folder at ~/Library/Filters

14- close all open windows

15- select the PDF file that’s too big and open it in the Preview app

16- in the Preview app, go to “File” and from the pulldown menu, select “Export” (do not select “Export to PDF” or “Save” or “Print” !!!)

17- in the window that appears, choose a (new) file name and a location to save the size-reduced PDF-file, then set “Format:” to “PDF” and at “Quartz Filter:” select “Reduce File Size 75dpi” and click the “Save”-button

18- then go to the Finder and select the newly created size-reduced PDF-file and right-click and select “Get Info” (or use the CMD+I key-combo), in the window that opens, check the file size (note : any file up to about 5MB can easily be sent as an eMail attachment)

19- then open the size-reduced PDF in the Preview app and check if the text is still readable… if  all text has turned fuzzy, do a new Export from the original PDF but choose another Quartz-filter (like 100dpi or 120dpi… if you didn’t create those, redo the entire process to create them and make them available throughout OSX)

20- that’s it ! you now have created a very handy and quick PDF size reduction option within the Preview app !

Enjoy !
