Patent ID: 7227551

Claim:
A graphic design method, comprising: receiving a mask comprising elements representing one or more inside regions, one or more outside regions and one or more boundaries, each mask element having a scalar value; receiving a constraint comprising elements corresponding to the one or more boundary regions and elements corresponding to the one or more outside regions, each constraint element having a value; receiving initial values for each element corresponding to the one or more inside regions and the one or more boundary regions; combining the constraint and the initial values using the mask into an accumulator, the accumulator having elements corresponding to the inside region and the boundary region, each accumulator element having a value; blurring accumulator values in accordance with a blur radius value; depositing the constraint into the accumulator using the mask; checking if the blur radius satisfies a specified criteria and, if it does, outputting those values from the accumulator corresponding to the inside and boundary regions, else adjusting the blur radius value and repeating the acts of blurring, depositing and checking; using the outputted values to adjust a display characteristic of an object; and displaying the object.
