Hi hamedi,

show an example VI!

Is this a picture in a 2D picture control or do you use VISION/IMAQ?

Do you really need a matrix or does a simple 2D array fit too?

Use a 3rd party tool to scale your picture before loading it...

[hamedi]

if it's possible for you please sent for me a vi

thank you so much

Hi hamedi,

I don't have a VI, I suggested to use 3rd party software!

Google for "scale jpg" and you will find tools like ImageMagick or similar! Use them to scale your pictures, call them with SystemExec...

GDI Resize works relativly well.  Here is an example taking a file and resizing it:
