View Ref-File7.4.6.103  vs_grayoverride                                         TOS

 Name:         »Override gray level«

 Opcode:       133

 Syntax:       void vs_grayoverride ( int16_t handle, int16_t grayval 
               );

 Description:  The call vs_grayoverride overrides the grey level 
               specified with the vsf_style call patterns 2,1 through 
               2,8. The application should specify the closest index 
               in the normal fill pattern set and follow it with a 
               vs_grayoverride call to "fine-tune" that gray level on 
               devices that support such fine tuning. This call is 
               currently implemented in the PostScript driver.
