Warning 36: File error in disini when I call metafl("wmf")

[Diane]

Hi, I wonder if anyone can help me.

 

I am a relatively new c++ and dislin user so I might have missed something simple.

 

I can sucessfully generate a plot on screen using metafl("xwin"), but cannot generate any files in wmf, tiff or pdf formats.

 

Here are the methods I am calling:

 

Dislin plot;

//Level 0

plot.metafl ("wmf");

plot.wmfmod ("standard", "format");

plot.setfil ("filename.wmf");

plot.scrmod ("revers");

plor.setpag ("usal");

plot.disini ();

//Level 1

plot.filmod ("count");

plot.pagera ();

plot.winfnt("arial");

plot.graf (xa, xe, xor, xstp, ya, ye, yor, ystp); // these are all set integer values, but I shan't bore you with the details

//Level 2

plot.curve (float* xray1, float* yray1, int n1);

plot.endgrf ();

//Level 1

plot.disfin ();

//Level 0

plot.symfil ("xwin", "keep");

Here are the warnings:

Warning 36: File error in disini!

Warning 3: Incorrect level in pagera! < 0>

Warning 3: Incorrect level in winfnt! < 0>

Warning 3: Incorrect level in graf! < 0>

Warning 3: Incorrect level in curve! < 0>

Warning 3: Incorrect level in endgrf! < 0>

Warning 3: Incorrect level in disfin! < 0>

Warning 21: The routine must be called after disini in symfil!

No file is saved to my workspace.

Same outcome for pdf, tiff, etc.

 

Thanks in advance,

Diane

Hi Diane,

I would change the order of the calls like this:

Dislin plot;

//Level 0

plot.scrmod ("revers");

plor.setpag ("usal");
plot.filmod ("count");

plot.metafl ("wmf");

plot.wmfmod ("standard", "format");

plot.setfil ("filename.wmf");

plot.disini ();

//Level 1

plot.pagera ();

plot.winfnt("arial");

plot.graf (xa, xe, xor, xstp, ya, ye, yor, ystp); // these are all set integer values, but I shan't bore you with the details

//Level 2

plot.curve (float* xray1, float* yray1, int n1);

plot.endgrf ();

//Level 1

plot.disfin ();

//Level 0

plot.symfil ("xwin", "keep");

Hi Diane,

The error message 'Warning 36: File error in disini!'
means that disini cannot create the file 'filename.wmf'. The other warnings are consequential
errors. Are you running your program from a directory, where you don't have the right
to create files?

Best regards,

Helmut

 

[Diane]

Thank you both!

 

Dr Rauthe-Schoch: Good suggestion, didn't clear the warnings, though I agree with your order and will keep it.

 

Helmut: You're absolutely right, for some reason I can no longer write to a file in my working directory. I have no idea why.

 

So it isn't a Dislin issue.

 

Thanks!

 

Kind regards,

Diane

Solved! It was a working directory problem. The working directory was inherited from a previous solution. Once I set the directory within the script, everything worked beautifully.`

 

Thank you for your help and also for such a fantastic plotting library!!

 

Kind regards,

Diane
