I just corrected that portion of the tutorial and thank you for noticing and informing me so I could correct the error.
Yes, if you look at the Move Path images in the tutorial, you will indeed see box2.png-1266 and then a forward slash (/), followed by the Layer name and an ID number (yours will be unique to your Gimp application) for example, in the first Move Path window shown it shows:
Again, your confusion is understandable, since your results will not be exactly the same. I named the image with the box layers box2.png so that I could save the various images to add to the tutorial. That was an oversight on my part. It would have been better for me to take screenshots of Move Path window with the Layers before naming that particular image. I will try to clarify that issue and update the images. My apologies.
Let me provide a bit more in depth detail about that particular issue. That section of the Move Path window is called Source Image/Layer . This means it will include first the Image name (thus the Image part - my image is arbitrarily named box2.png since I was using it for screenshots for the tutorial) followed by a unique ID number. It is then followed by a forward slash (/) and then the Layer name (hence the Layer portion, in the above paragraph, it is Box1 followed by a unique ID number which varies for each person running the software).
Finally, if you have no colors, make sure that your images are in RGB Mode and not Greyscale or Indexed:
Found under Image | Mode in your image window.
Again, I appreciate the feedback, even when things do not go right. That way, I can attempt to explain the problem and eventually correct it for the tutorial. It is important to me that others be able to follow the tutorial. I'm very glad that you are someone who pays attention to details. If you notice any other problems with the tutorial, please feel free to post them as well. That is the spirit of open source in my opinion. Just as with coding, one person may make the code open source, but then others can make corrections to improve the code for everyone, so too with my tutorials. Again, my apologies for any confusion, thanks for trying the tutorial and hope these explanations help some. :h:
