Hi

I've been looking for a DLL that has graphic drawing functions that can be called from within an Opus pub. While the new v6 drawing functions could substitute for some of the drawing needed, the end-user would need to be able to draw several more items not available in the v6 draw function pallette, plus be able to erase "mistakes."

Searching extensively online, I haven't been able to locate any appropriate DLL's and am hoping for some leads.

Kind Regards,

Hi Stephen,
rather than using a DLL, why not create your own drawing functions?? This would be a much easier route. You could then have a function for 'any' shape.
the pseudo code for a function would be





and to call the function you would have DrawTriangle (A,B,C)

to erase, you just call the function again using the background colour.
You have to be aware with drawing tools. If you look at the new examples --the freehand drawing, for example..... try it and just keep drawing, eventually it gets slower and slower response--as if it has to store and redraw every segment at each screen refresh--eventually.... instead of a smooth freehand line, you get short strainght sections, but for most uses, you probably won't suffer this effect.

Hi Sandy

Thanks for your reply and helpful suggestions.

So far, the design I've come up with: since I already have a drop zone box with pedigree symbols cloned, dragged and dropped into it, saved (including all display data) and able to be re-loaded, I would add a transparent drawing frame on top for lines that can visually connect the symbols below. The trick will be getting names for these multiple lines, so they can be saved (including all display data, especially pos and angle)then re-loaded at a later boot-up of the pub.

A bit of tough going for me, but an interesting challenge.

Again, thanks for your suggestions.

Kind Regards,

can't find freehand drawing example publication

Hi Craig,

Maybe I am misunderstanding what you are looking for. The sample I am referring to is in my full version of Opus 6.4, but I am not sure it is in the trial version.

Browse Sample Publications>New Feature Highlights>Drawing Tools

In this drawing tools pub, you can select a freehand line drawing tool to draw on screen in a frame.

Kind Regards,

I don't have that in the trial - any chance you could pot it on the forums?

I just want to see what's possible

Hi Craig,

I suspect this is something you could ask DW support to send you.

Not sure why its not in your version, but not mine to give away.

Check with DW.

Kind Regards,

Surely it's there. At least I thought it was included back when on trial. "New Feature Highlights" is the Pub. Drawing is one of the pages within it.

No it's not there

Try emailing DW, they might let you have a copy.
