Hi,

I have the feeling that some of my plugins work faster on 16-bits image
than on 8-bits images, I should stay 4 times faster. The only difference
is in the access to the pixels :

if (getType() == SHORT) {
return ((short[]) processor.getPixels())[x + y * sizex] & 0xffff;
                } else {
return ((byte[]) processor.getPixels())[x + y * sizex] & 0xff;
                }

Has anyone encounter the same behavior ? I have java 1.5.0_13 on linux
emt64.

Thomas
