/* gdevdsp.h - callback structure for DLL based display device */
#ifndef gdevdsp_INCLUDED
# define gdevdsp_INCLUDED
/*
* The callback structure must be provided by calling the
* Ghostscript APIs in the following order:
* gsapi_new_instance(&minst);
* gsapi_set_display_callback(minst, callback);
* gsapi_init_with_args(minst, argc, argv);
*
* Supported parameters and default values are:
* -sDisplayHandle=16#04d2 or 1234 string
* Caller supplied handle as a decimal or hexadecimal number
* in a string. On 32-bit platforms, it may be set
* using -dDisplayHandle=1234 for backward compatibility.
* Included as first parameter of all callback functions.
*
* -dDisplayFormat=0 long
* Color format specified using bitfields below.
* Included as argument of display_size() and display_presize()
* These can only be changed when the device is closed.
*
* The second parameter of all callback functions "void *device"
* is the address of the Ghostscript display device instance.
* The arguments "void *handle" and "void *device" together
* uniquely identify an instance of the display device.
*
* A typical sequence of callbacks would be
* open, presize, memalloc, size, sync, page
* presize, memfree, memalloc, size, sync, page
* preclose, memfree, close
* The caller should not access the image buffer:
* - before the first sync
* - between presize and size
* - after preclose
* If opening the device fails, you might see the following:
* open, presize, memalloc, memfree, close
*
