Choose image for infill direction
Select image to specify infill direction for the
Optizor infiller. Supports only .png, .jpg and
.bmp images with either RGB or RGBA formats. IceSL
calculates the angle based on a conversion to
grayscale using a normalized (i.e., [0-1]) average
of the RGB channels (i.e., (r + g + b) / 3). The result
is mapped (i.e., multiplied) to an angle between
0 (vertical) and 180 degrees. If no file is chosen,
IceSL defaults to the infill direction parameter.
