// single
convert Chun.png -background red -flatten  png_small.jpg

// and compress
convert moom_ref.png -format jpg -quality 85% test.jpg
convert moom_ref.png -format jpg -strip -interlace Plane -gaussian-blur 0.05 -quality 85% test.jpg


mogrify -format png -density 100 -colorspace sRGB -background transparent -units PixelsPerInch -resize 2475x3525 *.eps
