hi. i am a newcomer to study dm642.

but now i want to use function(IMG_wave_horz) int the imglib about c64xx.

how can i set the parameter about the filter.

for example: the low filter about harr is [0.717,0.717,0,0,0,0,0,0];
             the function request that the data type is short, so i use
the filter [1,1,0,0,0,0,0,0], but the result is zero regardless diffient
input data.

what can i do.

thanks.
