Using with F90

When using this driver with Fortran 90, a use statement is required at the start of the routine that makes the call to the device nomination routine as follows:

use gcgm_f90

File Format

Both character and binary encodings of the CGM driver produce a file containing a single stream of eight-bit bytes with no record structure.

All nomination routines will always generate files with metric scaling mode as GINO operates in a real coordinate system rather than an abstract one.

Multi-Pictures

More than one picture can be stored in any CGM metafile and the routine gNewDrawing() is used to separate each picture.

CGM Elements

The full list of legal CGM element identifiers is given below together with notes on their use by the GINO generator and interpreter.

Y= This element is generated/interpreted by the GINOCGM software

N= This element is not generated/interpreted by the GINOCGM software

I = This element is ignored by the GINOCGM interpreter

Notes:

1) Generalized Drawing primitives are interpreted as a polyline

2) All text is interpreted in software transformed mode

3) Pattern fill style is not implemented

4) Cell arrays are output as one element if the number of 'components' (nx*ny) is less than 2048. If the number is greater than this, the image is encoded as a series of cell arrays representing each row of the cell array.
