IMG_ERR_ROI_WIDTH_NOT_ALIGNED error

[hidezo]

Hi,

I'm trying to vertilcally bin a image on CCD-chip down to 1 pixel through PIC-1422 on NI-IMAQ4.1.0 on LabView8.6.1. I did in the case of more than 4pixels (i.e. N x 4 pixels). However, I got IMG_ERR_ROI_WIDT_NOT_ALIGNED when bin size is set to 3 or 2 or 1.

Of course, I modified the camera file when bin size is 3 as follows,

AcquisitionWindow (0, 0, 512, 3)

My question is that is there any way to avoid this error?, say another 3 dummy lines are added to one-line image data(Nx1pixels) on the board memory before read the buffer....

thank you.

Dear hidezo,

Thank you for using our discussion forum.
This is Miyagi from National Instruments.

The phenomenon you are seeing is a bug of IMAQ and there is no workaround.
It is not fixed in the latest version of of IMAQ yet.

It is planned to be fixed in the future version but we don't exactly know when it will be fixed.

I'm very sorry for the inconveniences.

Sincerely,
Miyagi
