Xtium-CL MX4 User's Manual CamExpert Quick Start • 41Image Buffer and ROI CategoryThe Image Buffer and ROI category groups parameters for the configuring the image buffer format,size and offset settings, as well as image flipping.Parameter DescriptionsThe following table describes the CamExpert Image Buffer and ROI category of Sapera LTparameters. Acquisition server notes, if applicable, indicate if parameter availablility or supportedvalues are dependent on the selected frame grabber acquisition server and acquisition device.DisplayNameParameter Description NotesImage Width (inPixels)CORACQ_PRM_CROP_WIDTH Cropped width of the acquisition image, inpixels; this parameter defines the width of theimage transferred to the frame buffer.The maximum width is the active horizontal ofthe image source (see the Horizontal Activeparameter in the Basic Timing category).Cropping increments depend on the selectedacquisition server; CamExpert automaticallyadjusts numerical entries to valid increments.Note: image data is not scaled.Image Height (inLines)CORACQ_PRM_CROP_HEIGHT Cropped height of the acquisition image, inlines; this parameter defines the verticaldimension of the image transferred to theframe buffer.The maximum height is the active verticalwidth of the image source (see the VerticalActive parameter in the Basic Timingcategory).Cropping increments depend on the selectedacquisition server; CamExpert automaticallyadjusts 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 ofthe acquisition image before transfer to theframe buffer.The maximum left offset is the activehorizontal width of the image source less oneincrement step.Cropping increments depend on the selectedacquisition server; CamExpert automaticallyadjusts numerical entries to valid increments.Note: image data is not scaled.
