IMAQ ReadFile, max file size smaller in run time mode

[Jos]

HI,

I want to load large images using LavbVIEW 8.5 and NIVision 8.6.

My program is basically very simple: 'IMAQ create' (grayscale (I16) followed by  'IMAQ Read File' and 'IMAQ Dispose'.

When I run this program in development mode it is possible to load 16 bit tiff files of 20kx20k pixels (780MB).

When I run the executable (run time) it is only possible to load 13kx13k images (330MB)

Development mode:

load program: used memory 50MB; load image (20kx20k =>780MB): used memory 1230MB; Dispose image still used a memory space of 445MB. NO Error.

load program: used memory 50MB; load image (13kx13k =>330MB): used memory 550MB; Dispose image still used a memory space of 220MB. NO Error.

Run time (.exe) largest tested image what can be loaded: 13kx13k (330MB).

load program: used memory 25MB; load image (13kx13k =>330MB): used memory 522MB; Dispose image still used a memory space of 190MB. NO Error.

Loading larger images results in an error: IMAQ Read File, Not enough memory for requested operation.

code : -1074396159

WHY is it not possible to load a large image in run time mode??

How can I resolve this problem?

Thanks.
