Image Buffer and ROI Category
The Image Buffer and ROI category groups parameters for the configuring the image buffer format,
size and offset settings, as well as image flipping.
Parameter Descriptions
The following table describes the CamExpert Image Buffer and ROI category of Sapera LT
parameters. Acquisition server notes, if applicable, indicate if parameter availablility or supported
values are dependent on the selected frame grabber acquisition server and acquisition device.

Name
Parameter Description Notes
Image Width (in
Pixels)
CORACQ_PRM_CROP_WIDTH
Cropped width of the acquisition image, in
pixels; this parameter defines the width of the
image transferred to the frame buffer.
The maximum width is the active horizontal of
the image source (see the Horizontal Active
parameter in the Basic Timing category).
Cropping increments depend on the selected
acquisition server; CamExpert automatically
adjusts numerical entries to valid increments.
Note: image data is not scaled.
Image Height (in
Lines)
CORACQ_PRM_CROP_HEIGHT Cropped height of the acquisition image, in
lines; this parameter defines the vertical
dimension of the image transferred to the
frame buffer.
The maximum height is the active vertical
width of the image source (see the
Vertical
Active parameter in the Basic Timing
category).
Cropping increments depend on the selected
acquisition server; CamExpert automatically
adjusts numerical entries to valid increments.
Note: image data is not scaled.
Image Left Offset
(in Pixels)
CORACQ_PRM_CROP_LEFT Number of pixels to crop from the left side of
the acquisition image before transfer to the
frame buffer.
The maximum left offset is the active
horizontal width of the image source less one
increment step.
Cropping increments depend on the selected
acquisition server; CamExpert automatically
adjusts numerical entries to valid increments.
Note: image data is not scaled.
