The answer is given by the definition of 'terms': terms = (row < 4) ? row : 4; In pratice, that means that - with row<4 the loop is for (i = 0; i <= row; i++) { ... } - with row>=4 the loop is for (i = 0; i <= 4; i++) { ... } Alastair M. Robinson

L7 shows the effect of curve3 alone. L8 shows the effect of the 3 curves applied together (by multiplying L5, L6 and L7). L10 shows how the 'quick mask mode' would appear after setting the 3 curves. David Gowers wrote: > Hi Stephane, > > On Nov 20, 2007 10:10 AM, Stephane Chauv
