Hello,
Is it possible to apply image processing only to certain pages in the document?
I would like to edit certain pages in the document with the greyscale filter.
For example, using a QR code on the relevant page.
My idea was to use a split operation, then check whether the QR code is present, then apply the filter and then reassemble the document. Unfortunately, I haven't found a way to merge the pages.
Hi,
You're on the right track, thinking step by step is exactly what works 
!
Once separated/splitted the document you need to find the merge point of the document after your image processing...so we always suggest an intermediate workflow (before the final output) that "appends":
Here you are some usefull info:
Best regards,

Thank you very much for pointing me in the right direction.
This workflow allows me to achieve the desired result.
As a prerequisite, I have a QR code with the value “ColorPage” on every page that is supposed to be in color.
First workflow:
1. Watch Folder (Path C:\IN\)
2. Barcode Reader (Reg.Ex. “ColorPage,” All pages, Use as separator)
3. Split trigger (On number of pages 1 to separate the pages after the color page)
4. Condition trigger (Condition Left operator "%BARCODEREADER_SEPARATIONPAGES%" Match RegExp "^.*\b%CURRENTPAGEONSPLIT%\b.*$")
4. true → 5. Windows File System
4. False → Image Processing (Filter Grayscale) → 5. Windows File System
6. Windows File System (Path „C:\INTERMEDIATE\“, Filename „%ORIGINALFILENAMEWITHOUTEXTENSION%“, If file already exists Append, output profile TIFF)
Second workflow:
1. Watch Folder (Path C:\INTERMEDIATE\)
2. Windows File System (Path „C:\OUT\“, Filename „%ORIGINALFILENAMEWITHOUTEXTENSION%%UNIQUECOUNTER3%“, output profile PDF)
