Hello! I have some problems with your program. Sometimes I digitize free-hand drawings, but have no money to buy version 8.7.
Surely, something may be done in free version?
This is a fragment of our field draft. I have two questions:
1) Can I digitize it in free version and 2) how???

Thank you in advance.

Well... I would not call this painting even "draft". Nevertheless:

1. One mask is sufficient to binarize the image.

2. Processing of extracted image is described in the previous post
"How to extract lines from image (JPEG, sepia, etc.)"
(diffusion, contrast increase, selection of the level of white color)

3. Autotracing, line correction and optimization are described in the HELP.

Thank you for your answer.

PS. This is not a draft - just a small fragment
