Graphics Function: Returns the status of the most recently used graphics routine.
USE IFQWIN
result = GRSTATUS( )
The result type is INTEGER(2). The result is the status of the most recently used graphics function.
Use GRSTATUS immediately following a call to a graphics routine to determine if errors or warnings were generated. Return values less than 0 are errors, and values greater than 0 are warnings.
The following symbolic constants are defined in the IFQWIN.F90 module file for use with GRSTATUS:
Constant |
Meaning |
|---|---|
$GRFILEWRITEERROR |
Error writing bitmap file |
$GRFILEOPENERROR |
Error opening bitmap file |
$GRIMAGEREADERROR |
Error reading image |
$GRBITMAPDISPLAYERROR |
Error displaying bitmap |
$GRBITMAPTOOLARGE |
Bitmap too large |
$GRIMPROPERBITMAPFORMAT |
Improper format for bitmap file |
$GRFILEREADERROR |
Error reading file |
$GRNOBITMAPFILE |
No bitmap file |
$GRINVALIDIMAGEBUFFER |
Image buffer data inconsistent |
$GRINSUFFICIENTMEMORY |
Not enough memory to allocate buffer or to complete a fill operation |
$GRINVALIDPARAMETER |
One or more parameters invalid |
$GRMODENOTSUPPORTED |
Requested video mode not supported |
$GRERROR |
Graphics error |
$GROK |
Success |
$GRNOOUTPUT |
No action taken |
$GRCLIPPED |
Output was clipped to viewport |
$GRPARAMETERALTERED |
One or more input parameters was altered to be within range, or pairs of parameters were interchanged to be in the proper order |
After a graphics call, compare the return value of GRSTATUS to $GROK. to determine if an error has occurred. For example:
IF ( GRSTATUS .LT. $GROK ) THEN
! Code to handle graphics error goes here
ENDIF
The following routines cannot give errors, and they all set GRSTATUS to $GROK:
DISPLAYCURSOR |
GETCOLORRGB |
GETTEXTWINDOW |
GETBKCOLOR |
GETTEXTCOLOR |
OUTTEXT |
GETBKCOLORRGB |
GETTEXTCOLORRGB |
WRAPON |
GETCOLOR |
GETTEXTPOSITION |
