Patrick8 Posted May 16, 2021 Share Posted May 16, 2021 (edited) Hello, 1mm is being added when I export to png. Is this is a bug or is there something I am doing wrong? Dimensions are meant to be 260mm x 300mm but are actually 260mm x 301mm. Any help would be appreciated.

firstdefence Posted May 16, 2021 Share Posted May 16, 2021 Morning (UK) Welcome to the forum @Patrick8 Which way are you exporting, from File > Export... or from the Export Persona? I may be because the pixels aren't whole pixel aligned, i.e X: 1.2px Y: 1.3px and the object is a fractional pixel size 300.2px check in the transform panel.

Patrick8 Posted May 16, 2021 Author Share Posted May 16, 2021 Hello @firstdefence I'm exporting via File > Export with a document setup of 260mm x 300mm at 300dpi. However when I go to export this is 3071 x 3544px, resulting in incorrect dimensions by 1mm. 30cm is equivalent to 3543.307... at 300dpi. However, for some reason this is being rounded to 3544px. Is there any reason why this would be? Quote Link to comment Share on other sites More sharing options...

firstdefence Posted May 16, 2021 Share Posted May 16, 2021 Under preferences there is a setting to show fractional units... Try setting the decimal places to more than 1 and see what readings you get then. If all else fails upload the affinity file for us to look at if possible.

Theoretically, you could have a clipping path in a file which cuts border pixels to half... but generally yes, some rounding have to be done. It is somewhat a problem that Affinity software respects more pixels than millimetres. Quote Link to comment Share on other sites More sharing options...

But you can't really cut a pixel in half because a pixel is the smallest unit of picture information possible in a raster image file. IOW, there is no way to change any properties of ½ a pixel & not change the other half in the same way.

Step into my world, the FDatrix, do you think they are whole pixels you are using?
