Image to g code, not working?

[CaptainVee]

Hey folks,

In the new emc the image to g-code software has been included. You can now open jpg's and other images in to emc without fuss. Or can you?

I have tried it several times but have not seen any results.

How long is it expected to take to open an image? More than half an hour?

Anyone had any success with this?

Sometimes running a program in a terminal returns a useful error.
What happens if you paste this in a terminal ?

image-to-gcode  $HOME/emc2/nc_files/examples/torus.png  >  $HOME/torus.ngc

That should post a file in the Home directory.
It could be a problem with the images you're using ? Post an example and I'll give it a try.
No promises, I'm far from expert with this stuff.

Hi CaptainV,

Used it recently to carve images into wooden disks, the results are in my gallery, once I had the settings worked out it seemed to work without fault, even remembering the settings from one run to the next.

My machine is running an old AND 1.2Ghz cpu with 512Mb ram, images were about 1200 pixels square.

I've been using emc2 for nearly a years now and recently have been trying to use the image-to-gcode program.
BUT not successful, I get an error :

File "/usr/bin/image-to-gcode", line 818, in ?
main()
File "/usr/bin/image-to-gcode", line 780, in main
nim1[tw:tw+w, th:th+w] = nim
File "/usr/lib/python2.4/site-packages/numarray/generic.py", line 618, in _broadcast
return _broadcast(arr, self._shape)
File "/usr/lib/python2.4/site-packages/numarray/generic.py", line 93, in _broadcast
raise ValueError("Arrays have incompatible shapes")
ValueError: Arrays have incompatible shapes

Appearently I'm not the only one facing this issue...

Appriciate the help in advance.

Sorry i'm late to the game, but i had the same issue last year. if you look back far enough in the linuxcnc forums you can find my thoughts on it. to be honest i dont remember exactly what i had done to make it work.
