amCentered

final int amCentered = acquireJNI.amCentered_get()

static

Use a small centered window for image processing.

In this mode, a device and processing function dependent window in the middle of the AOI captured from the device will be used for the processing function.

Since

2.37.0

Example:

• Assume a device that can deliver 1280*960 pixels.

Now in the centered AOI mode a processing function will use a window smaller than the AOI in the middle of the image.

The starting point can be calculated by the formula:

offsetX = ( width - ( width / 2 ) ) / 2
offsetY = ( height - ( height / 2 ) ) / 2

The used AOI is just width / 2 * height / 2 thus takes up the center quarter of the selected AOI.

In case of an AOI defined by the user, the central AOI of the delivered image is used.

Deprecated

Up to version 2.36.0 the AOI had just a size of 50*50 pixels. The behavior was the following:

• Assume a device that can deliver 640*480 pixels.
• The user selects to capture an rectangular AOI starting at 100/100 with a width of 200*200 Now in the centered AOI mode a processing function will use a window smaller than the AOI in the middle of the user defined AOI. This e.g. could be a rectangle starting at 150/150 with a width of 100*100.

amFull

final int amFull = acquireJNI.amFull_get()

static

Use the complete image for image processing.

amUseAoi

final int amUseAoi = acquireJNI.amUseAoi_get()

static

Use a user defined AOI window for image processing.
