Abstract
Abstract A method of sharing glyphs between a source computer and a destination computer having graphical user interfaces includes the step of receiving a first request to display a specified glyph at a first position of a source computer display. A glyph bitmap is created from the specified glyph if an identical glyph was not previously sent to the destination computer. The glyph bitmap is sent to the destination computer. The first request is also sent to the destination computer. The destination computer stores the received glyph bitmap. The first request received by the destination computer is replaced by a second request. In response to the second request, the second computer copies the glyph bitmap to the first position on a destination computer display.
