Lego picture with bigger brick outlines
Hello,

I have a very specific problem. I've created a Lego instruction with MLCAD and LPub. Both programs work fine.
But when I have a couple of black bricks next to each other it is very difficult to see the outline of each individual brick. Here is an example:

You can see the fullsize image over here.

My question is: How can I make these thin white lines between the black bricks bigger? And when it is possible, can I do this using a batch process?

I hope you can help me.

Best regards

konze

RE: Lego picture with bigger brick outlines
Try this:
  • Select by color (low threshold)
  • Click anywhere on black (this doesn't select the lighter lines)
  • Select/grow, use enough pixels to just include the outlines (2px)
  • "Filters/Generic/Dilate" (widens the outlines by a couple of pixels

I don't really know how you can automate the click on black...

Thank you for this example.
