I've been looking for the entire forum but i can't find anything about it. is it there a way to export/save the image without the base? Also i would like to send it via php without the base/canvas.
It seems most people are either deleting the base layer every time they export the file from WooCommerce (which is a lot of work), or you have to use the external admin.fancyproductdesigner.com platform (also a lot of work). Info here. Exporting is a much discussed theme here, and in need of improvement. I recommend you read this thread and this one.
