Please use only high-quality images. We recommend that the long dimension of your image be between 3000 and 4000 pixels, either in width or height. Lower size images may cause some issues.
You should estimate a run time of 1 to 5 minutes for each image in this pixel range, although this may change depending on a number of other factors.
The Gizmo Pencil Drawing plugin is designed to operate exclusively with JPG images. Please ensure that your image is in RGB Color mode and 8Bits/Channel.
