Abstract
A text image stretching system in a VGA for a plurality of text image font sizes comprises a plurality of cell line replication registers having inputs and outputs, the plurality of cell line replication registers formed into groups corresponding to one of the plurality of text image font sizes, each cell line replication register having a plurality of bits, the inputs of the plurality of cell line replication registers connected to the VGA to receive cell line replication information for storage in the plurality of cell line replication registers, a multiplexer having data inputs, first and second select inputs and a plurality of outputs, each of the data inputs connected to one of the plurality of bits of the plurality of cell line replication registers, the first and second select inputs decoded to select one bit from each of the cell line replication registers in one of the groups of the cell line replication registers to form a cell line replication code for output on the plurality of outputs, a repeat counter having a plurality of inputs and an output, the plurality of inputs connected to the plurality of outputs of the multiplexer to input the cell line replication code to form a repeat value, a character cell height register having an input, and first and second outputs, the input connected to the VGA to receive character cell height data, the second output connected to the second select input of the multiplexer and a cell line counter having first and second inputs and an output, the first input connected to the first output of the character cell line height register, the second input coupled to the output of the output of the repeat counter, and the output connected to the first select input of the multiplexer.
