Simple drawings weren’t made into very good likenesses for the dot to dots. I could not use them. **Developer response:** Thanks for the feedback, and sorry to hear the dot-to-dot feature isn’t working well for your drawing. As promised, we have released 0.3.5, which has features that specifically address the dot to dot likeness for "simple drawing". To get the best result for simple drawing (line art instead of picture), please try to use the following settings under PUZZLE SETTINGS. Those settings work best if the picture is already line art; please don't use it if the input is a photo. || Preserve Simple Drawing Quality: On || || Bypass Sobel for Simple Drawings: On || || Path Tracking: use the minimum values for all 3 settings || Also can try to increase render size if phone has enough memory: || Render Size: 2048px || The other setting that can be optimized is 'Source Enhancement' under IMAGE PROCESSING. That works well if the image has lower quality e.g. needs a contrast boost. May use one of the pre-configured profiles under Source Enhancement to increase contrast, sharpness etc. Please feel free to contact us at explainthisapp@gmail.com ## Frequently asked questions about Dot Studio ### How does Dot Studio turn photos into coloring pages?
