Question

Align to grid

I purchased a pattern (someone else's design).  It was very small and on multiple pages.  Making it larger is an easy adjustment in Photoshop, but splicing the pages into one pattern is proving troublesome.  I scanned a paper original and my gridlines and page edges are all wavy.  I've tried distort and puppet warp with very slight improvement.  I'll get one corner aligned and the one I just fixed will pop out of alignment.  Also, because I'm distorting them, the gridlines on the two pages do not line up.  Someone else suggested I try liquify, but even after watching several tutorials, I'm not figuring out how it works on my particular image.  Are there any other ways of aligning an image or path to a grid or frame?

    You would need to define a new pattern like the one you purchased but sized larger. Here I outliner 8 pattern each looks empty in the thumbnail. Actually all a black square outlines. Each is a different size square 25px, 50px, 75px, 100px, 150px, 200px, 250px and 300px.  I filled a layer with each.

    It's not my grid or my pattern.  It's one I purchased and scanned in.  I would recreate it myself, but that would be VERY time consuming.  It's several thousand squares across and over a thousand vertically.  As far as I know, I'd have to recreate each square one at a time.  I can't just overlay my grid on top of the pattern because very few of the symbols would line up with their assigned square.

    Please see my sample image (orange and black) above because I still don't think you understand my problem.  What you see is a sample of one corner of one page.  Copying and pasting the scans into one document is super simple - and not the problem I'm having.  Where I'm stuck:

    Each page has a grid printed on it of 250 squares wide by 400 squares tall.  Each of those squares is filled with a symbol that indicates the appropriate color needed.  I have straightened each page as much as possible and cropped each page as near as I can.  However, each of the printed gridlines does not show in the scan as a straight line.  Each gridline is wavy and distorted.  When I put the pages next to each other, even if I line up the top squares perfectly, by the time I scroll to the bottom of the page, the gridlines are way off and the rows don't line up.  Plus, because the gridlines are wavy along the x axis and the y axis, some grid squares are right next to each other along the seam, others have an inch gap between them and the next page.  I'm wondering if it is possible to select points along a non-straight line, tell Photoshop they are supposed to be linear and have Photoshop adjust the image accordingly.


    The sample you showed/posted did not have the wavy lines and the distortion issues you now write about.   To me it sound like the process you used to straighten and crop the scans introduces your problems.    There is no magic pill that will  straighten your line and remove the other distortion you introduced.  How did  you go about straightening and cropping your scans. What interpolation method was used in the process. How did you scan the patterns.  Where the Patterns your purchased not image files of some kind.

    I'd abandon what you are doing, and start again by making a seamless pattern

    If there is scroll work involved, you need to use the grid, and plan where to take the pattern from.  If you'd like to paste some of the sroll work to this thread, we can give you step by step specific help.

    [EDIT]  I have just read your post again, and I am wondering where on earth I got scroll work from?  Show us what you are dealing with, and I am sure someone will help.

    It's a cross stitch pattern.  It has little icons in each grid square representing the color that was supposed to be used.  I hesitate to post it here as it is someone else's copyrighted work.  I have included just a very small corner of the pattern I'm trying to fix.  I know it doesn't look that crooked, but it's enough to make the pages not match up and the rows not line up.  It's not just a straightening issue either.  Looking at the whole edge, the grid lines are wavy.
