how to resize bmp?

[nicesg]

I can read a bmp and display it.

but if i load a 1024*768 is too big to display.

How do i resize it into a smaller window?

I mean how to make a big graph fit to a smaller window?

(the vi I found in forum)

Modified your VI to shrink the image.

Use the zoom factor property node as shown

For example, to decrease the size of the image to 50% of its original size, wire a value of 0.5 to this property. To increase the size of the image to 200% of its original size, wire a value of 2 to this property.

Its optional if you want to use the draw area size property.

hope this helps

thanks Dev, that is what I need!

but I am still thinking change it more suitable zooming, maybe...it can increase with or high individually...

I mean I create a control before (draw area size) it will use handle to change size...

how about this

[devchander]

well, stretching in one direction( height, width) cannot be done with picture function in LabVIEW. i am not aware if there are any addon toolkits for achieving this.

and i could not open your Attached VI. it must be in LabVIEW 8.0 or higher

Hello,
I had to handle that problem before & made this VI. The Main-VI is "load and scale picture 24-Bit Map V 2.vi" and the work-doing Sub-Vi is "Scale down V 2.vi". Some of the comments are in german, I hope this doesn't matter too much.
And I have to admit, it's not very fast.

An  implementation I did once can be found here. It will stretch or "compress" the image as needed and can either maintain its aspect ratio or distort it to fit a specific size.
