    摘要: A stiff, water resistant laminated medical or veterinary dressing is described along with a procedure for forming the final hardened dressing. The dressing is obtained by treating a gypsum bandage with an aqueous dispersion of a synthetic resin and then forming a layer from it which is immediately adjacent to a layer formed from a water hardenable synthetic resin bandage. Either layer may be formed first and further layers may be formed so long as the layers alternate between those formed from wraps of the gypsum bandages and those formed from wraps of the synthetic resin bandage.

    摘要: In a method for determining weighting factors for the color calculation of a color value of texels for a footprint covering a plurality of texels in a texel grid, in a graphic system, form information of the footprint is determined at first. Afterwards, the edges of the footprint are determined and the edges determined in this way are approximated by a staircase function. The texels of the texel grid contacted by the staircase function are determined and a weighting factor is determined for each texel containing a portion of the staircase function, depending on the subarea of the respective texel covered by the footprint.
