These compounds and their pharmaceutically acceptable acid or base addition salts can be used for preparing medicaments for modulating estrogen related receptors, and treating metabolic diseases, such as high blood fat, fatty liver, hyperglycemia, diabetes, obesity. The self-contained image processors and image normalization engine access image data from a memory array; the array is fed data from a multiplicity of imaging modules operating in parallel. Therefore, on the basis of the dot-size differences of dots printed by different groups of discharging elements, the print heads and the image-receiving member displacement means are controlled such that in operation, for a given print mask, an optimal number of discharging elements is actually image-wise activated and an optimal displacement distance in the sub scanning direction is determined.
