  1. Wrong exported image size (extra pixel added) if artboard coordinates are non-integer, not pixel-perfect

    How important is this to you?

    This issue is probably happening because the artboard dimensions are not appropriate for raster export (i.e. are in decimals).
    If you make x and y values as the whole numbers in the transform panel (not in decimal), then the extra pixels will not be added to the exported image.

    That is the workaround, and it’s reported that it’s not always the case.

    At the same time — Ai knows the size of artboards to be exported and yet it does not deliver the set sizes, which is not fair. The team is going to rethink the algorithm.

    This is still a bug! Yes, rounding the artboards to whole integers does work - if you are working in pixels. However, I'm currently working in mm because I'm designing a business card and it needs to be 88x58mm with a 3mm bleed. Even if I round the artboards to whole integers when working in mm, working from the Top Left of each artboard, it still exports different sizes. Eg. my Illustrator file with seven artboards each of exactly 88x58mm, with the top left corners set at (0,0) (100,0) (200,0) (300,0) etc. outputs some JPG's as 1040x686px and some at 1041x686px.
    If I want to position a guide line at exactly 3mm for a bleed I then have to get a calculator and work out the measurement in pixels and set the position in Illustrator by typing in 35.45px
    Until they change paper sizes to be in pixels then can I suggest you prioritize Illustrator to work correctly in mm, inches, cm, etc. etc.
    Thanks :)
