Its avoid to have that create a new hal component and read external mask file.

Would you be interested in helping develop an idea I have for a HAL component that loads image files and laser-rasters them? All without G-code or Axis or the rest of LinuxCNC?

Sure. I am disposed to help in anything that I can contribute.

I have that can the same idea but with CorelDraw evaluating the vector information and generate G-code for raster. it is a part for my thesis.

Well, I have run out of time on this (I spend most of the next month abroad away from my LinuxCNC machines) so here is a taster of what there is so far (not a lot, to be honest)

If you extract the attached file into the configs directory and then navigate into the directory in a terminal window and
halrun -I -f laser.hal
Then it will load up the UI, realtime component and halscope.

Then, if you set the halscope going and
setp laser_rt.start 1
at the command prompt you ought to be able to see the x and y command positions changing to generate a raster.

What isn't there yet:
A button to start
The stepgens in the HAL file (easy to add). It actually ought to be capable of generating a raster if connected to hardware.
homing
jogging
scaling
(The big one) any link to the actual image data. The GUI will load a file though, and does put it in to shared memory, and the realtime component can see it.

I will get back to it when I am back at home. Feel free to ignore it, or develop it, as you prefer. I was hoping to provide something a little more useful.

oops..wrong thread.
