Hi, I have a plot and I would like to overlay a PNG image over it. I'm using the rasterImage function to do this, but the problem I'm facing is working out the coordinates of the upper right corner of the final image in user coordinates.
That is I can place the image so the lower left is located at the bottom of the y-axis and the left end of the x-axis. Since my image is say 100px x 100px, is there a way for me to convert a 100px length into the appropriate value in user coordinates, along the x-axis?
