Creating Tubes
Start with the image you wish to make into a tube.
You can save this one if you like
Then open a new transparent image by going to
File and then New
Then set the width and height to match your image that you started with
And in the drop down menu choose transparent
Then you will have this in front of you
Go to back to your original image and go to
Edit then Copy
Then back to the transparent image and go to
Edit and paste as new layer
The image will look like this
Then go to selection and then select none
Then on the side tool bar, click on the eraser
For larger pictures you can start with a high setting
Then start to erase the background around the boot
or object you wish to make into a tube
Once you have almost all the background erased,
Change the setting to a smaller size eraser
The go to view and zoom in by at least 1
This will give you a clear view of the edge you are trying to clean
so that you can clear all the background off from behind the object
Once you are satisfied that you have it clean enough,
Then go to view and normal and this is what your boot should look like
Now go to File and down to Export and then Picture tube and name it and save it.
Now go ahead and have some fun!
