Set the minimal zoom percentage value of a form for it to be considered for capture. This controls the quality of the captured form.
The IDC firmware rejects capturing a form unless the width is at least the IDC Zoom Limit percentage of the IDC Width parameter. For example, if you set this parameter to 100 and IDC Width to 150, the form must be at least 300 pixels wide before it is captured (each unit module is scaled to two pixels).
