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

In attached AI file there are 1 artboard if you just export it for Screens you will get an image size 105px × 104px, however in AI it's sized as 104x104px.
Check that X coordinate of artboard is 172.34 px, so it's float. Just change it to 172px and re-publish and image will be 104x104.

So, coordinates of artboard should affect into output PNG image.

Also, should be related too:

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.

    Hi Team

    When you export artboards as Jpg, it gets exported with 1 Pixel short.
    Can it be fixed.

  • Justin Lowery commented  ·   ·  Report

    This bug is still present in Illustrator 25, CC 2021. So it is incorrect to mark it as resolved.

  • Justin Lowery commented  ·   ·  Report

    Can you please make it not round up when the artboard pixel position is set in floats? This is not a feature, but a serious bug! This has made my life **** for weeks as I have tried adding bleeds to all my images due to white and colored edges being tacked on at export, on both Mac and iPad versions of Illustrator! People who don't know about this will be driven mad by all these extra pixels and colored edges being added onto their exports, especially when, like me you have 32 layouts under deadline and all of them have these stupid extra pixels being added on seemingly at random. And if you miss them then clients catch them and complain that the file sizes are wrong. It is absolutely unacceptable. This must be fixed ASAP. Illustrator should discard the added pixel rather than adding it on. All exports should perfectly match the artboard size, regardless of placement on the canvas.

    Doesn't seem to be affected with or without bleed, both export wrong size

    If document setting is set to pixels instead of inches, the export is off by 1 pixel

    I have noticed this problem on CC2020 as well as 2021 version exporting files the wrong size.. typically off .003 - .007 (inch) - Example a 1x1 in square with a .05 in bleed all sides "export as" with artboards exports as 1.1 x 1.103 in. A 3.5x1.25 in exports as 3.603x1.603in

    Attached is a simple sample file.. few different sized artboards

    When exporting I've confirmed JPG, PNG, TIF (and perhaps others) all export the wrong size when a bleed is set in document settings.

    I've tried various bleed settings and does not seem to change the sizes still are being exported wrong sizes. This problem didn't exist in the 2019 version thus some update in 2020 brought this on.

    Obviously this must be exhausing for Adobe dev team... :(

    I am trying to do some titles for a video 1920 x 1080 resolution, and when "export as" is used to rasterise the the title panels, they come out at 1921 x 1081 which is causing many problems down stream of the files I created.

    AsI'm "Exporting for Screens" few dartboards at once I have 300 by 600 pix one. It is EXACTLY this size as dartboard, but the JPG comes az 300 by 601 pix.

    Have tried various file types with same results

  • Steve commented  ·   ·  Report

    Testing exporting, seems export sizes off by a few thousandths.. with or without bleed... Usually off .003 oversize on the width

  • jayse commented  ·   ·  Report

    This might be due to an old bug where if your art-board is positioned on a half a pixel, like 768.5 on the x, rather than a whole pixel, like 768, it will change the export by adding 1 pixel. Was super hellish for large projects! For sure!

    Not sure if it's fixed now (it's widely reported) but hope that helps if anyone else finds this.

  • Terry Chu commented  ·   ·  Report

    Basically, whenever I export something like an image setting my artboards width and height as a whole number, depending on where the artboard is positioned at a decimal value i.e(x: 1200.232 y:200.623). There is a bug where it will export the image with an extra pixel. So if I've set the width to be 1000 pixels and the height to 400 pixels, for example, it will export this as 1001 x 401 pixels. To fix this problem, I have to always make sure the artboards are positioned at x: 1200 y:200, deleting the decimal values.

    Unless of course, the bug itself is easy to fix on your end, this is my suggestion of a way around that problem.

    Another idea is to have the repeat function (ctrl/cmd+D hotkey) work for creating artboards also.

    Thanks
