center image in a display

[llebras]

Hi,

In my project, I have to display 2D images in a display indicator. I change with succes the zoom factor, so one dimension of the image (the largest) fit with the display. For the other dimension (the smallest) I would like to place the image at the middle of the display.

Therefore, I calculate the offset that I need but when I send the offset to the "draw unflattened pixmap" VI, the image is shifted but not exactly on the middle... See the image below:

I attached my VIs :

OK sorry, I finally find the errors :

- I didnt take into account the zoom factor in the offset calculation. I didn't know that the offset was set according to the pixel in the image, I thought that it was set according to the display length.

- I had to recreate my display indicator as if the old one was corrupted by too much manipulations, and there was an additional offset even with the right calculation...
