Open Image and SuperImpose a Control on Top of a section in Image

[Anonymous]

This is a loaded question, because, I cant seem to find a single VI
that opens and displays a jpg, bmp, etc!

But assuming, I find a toolbox or create my own that will open/display
an image, lets say an picture of a car's
dash panel.. could I place a gauge/dial meter ON TOP of the place in
the image where the real gauge exists??

If it can be done in Labview, how difficult would it be for a
beginner??

Ist this to be a dynamic display.  If not copy and paste the image directly on the Front pannle and place the controls ontop of it.  Otherwise, open and display the picture in a picture box.  There are vis for opening many types of graphics and putting it in a picture box, then move the controld using property nodes to the correct location.  The dynamic case is alot of work.

Easy!

Display your background image and then place gauges on to of it. You can make the background of the gauge transparent.

(If this is a real gauge on the image, just photoedit the needle out of the background image and then hide even the scale of the LabVIEW gauge, showing only the needle.)

Here's a quick draft:

Sweet!

Now looking at your Block Diagram, are those 3 VIs outside of the loop
part of Labview 8.2 or
something you made?

What about the gauge, I dont see any "appearance property" for
transparency in the version I have (v5+) .
Is the transparent feature elatively new?

Everything is part of LabVIEW but I don't know what is available in version 5.

left to right outside the loop: "read PNG file" (there is also a similar one for JPG and BMP), "draw flattened pixmap", "Image terminal".

Transparency is part of the color palette. Just use the color tool and select the transparent color.
