Hi I'm using this awesome plugin with Export Add-on extension but I have some problem. I have for examle in product bulder set canvas height and width 800px and size heignt and weight 205mm. I'm using svg mask for this and printing box 800x800px. But sometimes customer add bigger image and I donload pdf with 800x812px. On some side is under png mask picture with some empty space. In addition this exported file has 202x199mm not 205x205mm.
