Write a LabView code that acquires a jpeg image

[chris696]

Hello,

i need help in doing the following on labview,

a. Decompose the picture into the RGB arrays and display each color (red, blue, and  green arrays)on separate graphs

b. Crop a 200pixels x 200pixels rectangle around the center of the image and display

can it be done ? 

Thank You

A good place to start is to look at the Picture Functions in the Graphic & Sound palette.

Hi chris696!

I suggest you to use NI Example Finder to look for sample code.

You can find this, in LabVIEW Help >> Find examples... menu.

Search for jpeg, and choose for exmaple ReadFileExample.vi from the reults.

Here are some hint regarding to the topic as well:
