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 availability or supported
values are dependent on the selected frame grabber acquisition server and acquisition device.
Display 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.
Image Top Offset
(in Lines)
CORACQ_PRM_CROP_TOP Number of lines to crop from the top of the acquisition
image before transfer to the frame buffer.
The maximum top offset is the active vertical height of
the image source less one increment step.
Cropping increments are acquisition hardware
dependent; CamExpert automatically adjusts numerical
entries to valid increments.
Note: image
data is not
scaled.
Image Buffer
Format
CORACQ_PRM_OUTPUT_FORMAT Data format for the acquisition image transfer to the
frame buffer.
The data buffer
format is
dependent on
the selected
acquisition
server; for
details refer to
the
CORACQ_PRM_O
UTPUT_FORMAT
parameter
description
Image Flip CORACQ_PRM_FLIP Enables real-time on-board horizontal image flip
function.
The Xtium2-CXP PX8 also supports a vertical flip
operation using CORXFER_PRM_FLIP.
Acquisition Frame
Length method
CORACQ_PRM_FRAME_LENGTH Specifies if the image acquired will have a fixed or
variable length in height.
Valid on in line
scan.
