I experienced some problems when exporting a figure with a map containing a true color image. Upon export the "linked" image was plain empty. I could track this down to line 2024 of the code "imwrite(pointc, ..."
pointc is changed to double (n x m x 3) a few lines above. If you cast it back to uint8, the imwrite command works as expected (i.e. "imwrite(uint8(pointc), ..."
I don't know if this is a case in plot2svg, which is just not handled or maybe if the imwrite command has changed.
Leonid - Yes, in the past I have had a few problems with errors in variables, easily enough solvable when the problem is purely linear. It gets a bit nasty when you have splines though. Sorry, but it is not something that SLM can solve. John
