The Cell Array is an array of rectangular cells with individual colours. It serves for passing raster images to GKS. Note that in general, colour values within the Cell Array do not correspond to picture elements (pixels) on a hardware display, and that all primitives, including Cell Arrays, are subject to the usual GKS transformations. The call is:
CALL GCA(PX,PY,QX,QY,DIMX,DIMY,ISC,ISR,DX,DY,COLIA)Neither the Cell Array primitive nor the function call arguments will be described in detail in this Primer, and the reader is referred to the GKSGRAL manual, or one of the texts in the bibliography, for more information.
