XTK lesson 13 (ami example) - Removing the boundary lines in slices obtained from 2D volume rendering

Question

I've implemented XTK lesson 13 from the AMI examples (this - https://fnndsc.github.io/ami/#xtk_lesson13) by passing a set of DICOM images.

In the slices obtained, there are these colored dotted lines that I'm assuming is a boundary of some sort. I need to remove them but I'm not sure what exactly they are. Can someone tell me how they are created or what they represent?

Edit:

I'm not at liberty to post a screenshot from my implementation but this is a screenshot from the example url. Sorry the image isn't very clear, the example loads super small images. The slice is the image on the bottom.

yellow dashed lines

When you move the image (slice) around in the actual example, the yellow dashed lines appear on the image. That's what I need to get rid of. I've also been referring to them as dotted lines, I suppose they are actually dashed lines. Sorry about that.

Answer 1

You should set stackHelper.slice.canvasWidth and stackHelper.slice.canvasHeight to 0 for the dotted lines to disappear.

Those dotted lines are meant to inform that a part of the slice if partially off-canvas.
