I have a gray image that I imported and embbeded into Inkscape. I used Path->TraceToBitmap using gray options so I get different layers of bitmaps. I then group or ungroup them.
I then draw a polygon using the Bezier Pen starting by the bottom left corner with 4 nodes all connected. Select them then select the polygon with shift+click and use the perspective tool.
I get two different but similar results if they were ungrouped the first one disappear if they were grouped they all disappear.
I saw that there were a lot of tutorials/answers on Stackoverflow or elsewhere on using the perspective tool (for instance this one or this other one or even this one) but I believe all the steps I took are correct.
Do you think there is a simple explanation to this strange behaviour ? Am I misunderstanding something still ?
EDIT: Apparently it moves the image to a 1pixel-1pixel aggregate which looks like a black sheet of paper folded multiple times. Any idea why it would do that ? Is it my drawing of a rectangle like shape with the bezier pen ?
PS: I have no notions on graphical design so my question this might be silly but I couldn't figure out the answer by myself.
