| description | A method, apparatus, article of manufacture for transmitting data to a facsimile presentation device is disclosed. In one embodiment of the invention, the method comprises the steps of receiving a presentation job comprising input data associable with at least one input grayscale value, retrieving at least one of a plurality of threshold matrices, each threshold matrix selected to control a grayscale rendering characteristic of the facsimile presentation device associated with the threshold matrix, applying the grayscale values to the retrieved threshold matrix to rasterize the input data, and transmitting the rasterized input data to the facsimile presentation device. This invention can be practiced in several embodiments, and permits the user to select the threshold matrix according to the presentation device and/or a selected presentation quality. In another embodiment of the invention, the apparatus comprises a means for receiving a presentation job having input data associable with at least one input grayscale value, means for retrieving at least one of a plurality of threshold matrices, each threshold matrix selected to control a grayscale rendering characteristic of the facsimile presentation device associated with the threshold matrix, means for applying the grayscale values to the retrieved threshold matrix to rasterize the input data, and means for transmitting the rasterized input data to the facsimile presentation device. |
