cropped and rotated image/canvas about drawbot_image_to_gcode_v2

[Scott-Cooper]

Hey NoPinky, I really appreciate the comments.

My particular robot draws better if I draw rectangular images vertically. Therefore I purposely rotate all my gcode to be taller than wide. If you don't want this bug/feature, comment out image_rotate(); in the setup_squiggles function. Unfortunately, right now, this also messes up other stuff like the directional strokes.

The auto center-crop can also be avoided by commenting out image_crop(); in the pre_processing() function.

I will also be adding a wiki to better describe my weird coordinate system, etc.
Hope this helps.

Hi @Scott-Cooper the wiki is still empty as it stands.

I'm quite curious about the crop. I'm also very much looking for a way to invert the Y-axis gcode for a normal pen plotter model. I've made my own pen plotter and am having a hard time figuring out where I can flip the Y-axis direction. I have found comments that someone has removed the - sign and added a - sign to the Y-gcode commands but somehow my gcode does not contain any negative values for Y.

Would there be a solution I can try out? Sorry for posting this in this topic, since I had two questions I thought I'd combine them since they are simple questions.

Thanks for this wonderful script, I am really having a good time with this!
