Merge 2D pictures

[Al1234]

Hi,

Is it possible to take several 2D pictures and combine them into one? I've tried several methods such as playing with pixmaps and raw data but unless I've missed the obvious I'm stuck!

I want to do something like this:

Thanks

Thanks for your help Andrey. Your link sent me down the right track.

Here's the solution:

Try dropping the png image below on to a blank LabVIEW diagram and you'll get a working version to play with...

This is crude way to mode pictures.

The pictures in your example are bitmaps (raster graphics), so getting a pixmap and moving it is harmless. If the picture contains vector graphics, you get bad results.

This will become noticeable when you use the picture control's zoom function. Zooming in or out a bitmap of vectors looks completely different than zooming in or out of the original vectors.

All things in the picture control's data are opcodes. Each opcode has additional data, like coordinates, colors and such. You can parse this data, check the opcodes and change it.

See the attached VIs.

Use it like this:

Just thought I'd weigh in here as I've been having serious performance issues using the out-of-the-box image manipulation VIs in LabVIEW (as suggested by other users).

Weibe@CARYA's solution is much more performant in my use cases.  It's getting my kudos.

Norm has a good set of code that helps translate 2D pictures pretty easily.

Combining this with the fact that you can concatenate them like strings means you can do some pretty cool things.  This ended being used in my Ribbon Interface.
