The VLab window is only available if a VLab card and the associated VLab driver libraries and classes are installed correctly.
This window allows image grabbing with the VLab card. Images can be grabbed and sent to a browse window.
To display an input monitor window, click the monitor on gadget. The speed the monitor updates depends on how busy your system is and how fast your CPU is.
Clicking grab, grabs an image from the VLab card and sends it to the browse window. The speed of this process is affected by VLab.mcc class settings. For the fastest possible grab, turn VMem off in VLab preferences in MUI settings. You will need to have enough available memory to do this. The conversion process from the VLab format increases the time taken to display the grabbed image as a proof.
Once the image is sent to the browse window, it can be shown (scaling is disabled), deleted or saved. If save proof or save selected proofs is selected, PhotoFolio detects that the image is a VLab grab and saves the image before it saves the proof. Once saved, the grab becomes a normal image and its proof operates like all others. The image is saved in the jpeg format.
Due to the slow speed of the grab function you can use quick grab. When quick grab is used, an image is grabbed from the VLab card, however no conversions are performed and the image is not sent to the browse window immediately. The image is stored internally and when you have finished grabbing, use build grab to send the grabbed images to the browse window. If VMem is turned on in VLab.mcc class MUI settings, this uses very little memory. A counter to the right displays the number of grabs currently stored.
Build grab sends stored grabs (grabbed with quick grab) to the browse window. This is the slow part of the process, so if a lot of images have benn quick grabbed, have a coffee! Each time an image is built the counter on the right decrements.
