Dear Group,
I am no longer able to save the contents of a cgWindow as a raster file. I am using cgWindow in the latest Coyote library, not the one in the experimental subfolder. When I try to save as a BMP, for example, the following three system error warnings appear one after the other:
First error:
CGCMDWINDOW::SAVEASRASTER--> Variable is undefined: BUTTONVALUE
The IDL prompt shows:
Traceback Report from CGCMDWINDOW::SAVEASRASTER:
Variable is undefined: BUTTONVALUE.
Execution halted at: CGCMDWINDOW::SAVEASRASTER 2236 C:\RSI\Libraries\coyote\cgcmdwindow__define.pro
CGCMDWINDOW_DISPATCH_EVENTS 1541 C:\RSI\Libraries\coyote\cgcmdwindow__define.pro
$MAIN$
Second error:
PS_END--> Expression must be a structure in this context: PS_STRUCT (_$FSC_PS_START_).
The IDL prompt shows:
Traceback Report from PS_END:
Expression must be a structure in this context: PS_STRUCT (_$FSC_PS_START_).
Execution halted at: PS_END 217 C:\RSI\Libraries\coyote\ps_end.pro
CGCMDWINDOW::SAVEASRASTER 2226 C:\RSI\Libraries\coyote\cgcmdwindow__define.pro
CGCMDWINDOW_DISPATCH_EVENTS 1541 C:\RSI\Libraries\coyote\cgcmdwindow__define.pro
$MAIN$
Third error:
CGCMDWINDOW_DISPATCH_EVENTS--> Expression must be a structure in this context: PS_STRUCT (_$FSC_PS_START_).
The IDL prompt shows:
Traceback Report from CGCMDWINDOW_DISPATCH_EVENTS:
Expression must be a structure in this context: PS_STRUCT (_$FSC_PS_START_).
Execution halted at: PS_END 201 C:\RSI\Libraries\coyote\ps_end.pro
CGCMDWINDOW::SAVEASRASTER 2226 C:\RSI\Libraries\coyote\cgcmdwindow__define.pro
CGCMDWINDOW_DISPATCH_EVENTS 1541 C:\RSI\Libraries\coyote\cgcmdwindow__define.pro
$MAIN$
I've had a brief look at the code, but can't see how to sort out the problem. Any help would be gratefully received.
Regards,
David
