Replacing colors in a picture control

[Gazebo]

Hi all,

I'm running into some performance issues with the frequent updating of colors in a picture control. This is the method I'm currently using to update the colors.

The picture contains only two colors; the color of the icon, and the pane color to mimic transparency.

is this method possibly too slow and could be the culprit of perfomance issues, and is there a better way of doing this?

Thanks

Hi Gazebo,

a loop-less approach:

It's not perfect as it creates datacopies and has a coercion dot inside, but may provide ideas!

You may even use ReshapeArray to work with a 1D array (in the core of the routine), LabVIEW usually is faster then…

you could get rid of one for loop and both the unflatten-pixmap.vi, if you used the image array from the image data cluster.
