[increase thickness in line drawings]

Thanks for all of your help, I tried each of your methods and then picked from each. I learned so much.

 

A couple of comments about each if I may:

MJW- Median didn't seem to do anything at first. I then realized that I had resized my working image so that it would upload, after I reduced the colors to just 6, your technique seemed to work

Ishi-I loved that 1px Expansion. At first it didn't seem to do much but when I zoomed in it is pretty cool that it increases everything by 1 pixel in each direction (I think). It did seem to do a little distortion in the purple and of course by increase size got some of his blue dots a little out of position, I just moved them a little afterwards

Ego Eram Reputo-Thanks for suggesting the Alpha Space plugin, it works very well. I liked edge expander except I kept losing the yellow center of the flower with it.

 

Again, thanks for all of your help and I appreciate how thorough your instructions were.  I hope my experience will help someone else that faces a similar issue.

 

One of the most valuable things I learned is that zooming in (all the way in) really lets you see what these plug-in do.

 

 

 

 

[increase thickness in line drawings]

A little background on what I am attempting to accomplish. When my 5 year-old grandson makes a drawing, I am tasked with scanning the picture, cleaning it up, resizing it, converting it to an embroidery file so that my wife can use her embroidery machine to sew the drawing on a "curtain" for display and memories.

 

I use paint.net (obviously) to clean up and resize the drawing; however, I am very new to paint.net. I understand most of the basic tools but I am very inexperienced at some of the more powerful features.

 

He recently drew a picture of a flower (attached); however the size of the lines in the drawing are too narrow to embroider well. They are about a brush width of 25 and need to be at least 45 for the embroidery to look good.

 

I have tried a couple of methods both of witch kind of work but are very time consuming.

Method 1 was to simply trace around his drawing with the paintbrush set to a width of 45. This keeps the general shape of his drawing but loses a lot of his originality

Method 2 was to duplicate his drawing in a separate layer, shrink it a bit, then in another layer enlarge it a bit and finally move parts up and down and left and right to enlarge the shape.

 

I was hoping someone could tell me how to accomplish this task in a better manner. I am assuming the instruction might be more advanced than I am so please give me as much detail as possible.

 

Thank you very much
