change width in draw line for LabVIEW 6.1

[AndyBE]

Hi
as I couldn't solve the problem up to now I'm posting this question again with the hint that I'm looking for a solution in LabVIEW 6.1. LV 7 has already a SetPen.vi where the style and the width can be chosen.

HI!
I wanted to draw thicker lines in a picture control in LabVIEW 6.1. I found some posts where they mentioned that I have to edit the according VIs. So I played a bit around but didn't get it working. I'll attach pictures of the diagrams of "SetPen.vi","DrawLine.vi" and "Draw
MultipleLines.vi". Can anybody tell me what to change or provide a suitable vi? Is there a tutorial where the code and the generation thereof for picture controls is explained?"

Hello AndyBE,

I noticed that there was a suitable response on your other thread. I believe it was posted after you created this new thread. Let me know if you still have questions regarding this issue.

Have a nice day!

Hi Robert,

thank you for your post. Matt F posted already a suitable example VI which I can use and edit. Still I have questions about the functionality of the picture control/indicator. In the draw line or move pen subVIs there are type casts so that all the data will be changed to one string. How does the Picture Control/Indicator interpret this code? Is the Interpretation of the code different through the LabVIEW versions (e.g. 6.1 to 7)? Is there any information out on this like tutorials?

Best Regards
Andy

Andy,

The format and specifications for the picture data type and unfortunately not published for public use. The supportability of the picture data type only extends to the functionality provided in the corresponding VI�s shipped with LabVIEW. You are welcome to play around with how it works, but know that it is not supported. I hope this does not provide too much of an inconvenience.

Have a great day!
