you can adjust the background image so that the card is white by using -recolor or possibly modulate
see http://www.imagemagick.org/Usage/color/#recolor
NOTE: apparently -recolor is now deprecated in favor of an improvement now called -color-matrix
see http://www.imagemagick.org/script/comma ... lor-matrix
for brightness/contrast, see -level, +level, -brightness-contrast, -auto-level, modulate (can also shift hues), etc
for shadows, there is no really good way, but see http://www.imagemagick.org/Usage/distorts/#shadow3d
for correct control points, see image coordinates vs pixel coordinates at http://www.imagemagick.org/Usage/distor ... rol_points
most things with examples can be found at http://www.imagemagick.org/Usage/ (good reading for beginners)
