Rotate PNG image with user defined angle

[Amit_Amrutkar88]

I tried rotating PNG image with attached code in LabVIEW 2016 version.

I took help from one of NI thread:

Rotating Graphics (Pixmaps) in LabVIEW 

http://www.ni.com/example/26943/en/ 

Now, I am able to rotate input image with user defined angle (in degrees).

You can take any PNG image with transparent background as a input file.

The image is with transparent background.

I want that image with transparent background to be shown in picture indicator.

It is currently showing white background.

Can somebody please help, how to achieve this.

use a mask

1# use a mask to render transparency in a Labview Picture Plot e.g.

National Instruments\LabVIEW 2017\examples\Graphics and Sound\2D Picture Control\Using Mask with Picture.vi

2# use Darin K.'s .vis to save this mask layer as an alpha layer  32 bit .png
