you can implement your own scaling algorithm to go from 160x160 -> 240x240. the concept is that you'll make a 2x2 grid a 3x3 one. thats the basis for your scaling. you can try this: [A][B] [C][D] becomes [A][E][B] [G][X][H] [C][F][D] E = avg(A+B) F = avg(C+D) G = avg(A+C) H = avg(B+D) X = avg(E+F) you can write scalers quite quickly; obviously, there are better techniques. however, faster = lower quality, slower = better quality. it really depends on the bitmap as well. -- // Aaron Ardiri -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
