I've been working with some graphics since last night. I have a square image and I'm tiling it into 2x3 to make a larger recurring pattern. Done this before and always worked fine. Last night I was doing this with a jpeg in Photoshop and I got the 6 blocks aligned, copied and pasted into a different document and there was a distinct loss of resolution.
I spent an hour and a half on live chat to Adobe and in the end the agent told me I should work with vectors in Illustrator and Photoshop wasn't intended to do this! We discussed raster images etc. and he tried everything dialled in but just said it's my image. So, I have a 55 inch square image that I shrink to around 1 inch square, no quality loss, I tile 2x3 and flatten layers, no quality loss. I copy and paste into a new document, noticeable quality loss!
I explained that I usually get jpegs to work with and rarely get vectors due to the nature of my business so that's no help at all!
So today I'm in the office, just happens this particular graphic I have an EPS file. I've tried tiling in Illustrator, I don't get on with it but had a go...still don't get on with it :-) Downloaded Inkscape, found this easier and tile feature worked very well. Left a pixel sized gap between the tiles, a known raster engine fault. Overlapping a micro amount seems to help but daft to have to do this.
I prefer CorelDraw, copy paste job done. Step and repeat is good but I can't get 2x3 as I need just yet. I'm finding when I zoom in to align the edges the PC is stalling. it'a s decent powerful PC with good graphics card and never had this issue so I think it's software related, the original image may be too large.
So, how would you duplicate a pattern image into a 2x3 tile to create one rectangular image without gaps?
