•
Stitching:
Use this function to enable the seamless stitching of digital tiles.
•
Use Save compensation image:
This function enables the use of previously recorded
reference images for all slides. Use this function when the slide is completely covered by
the specimen (for example, blood smear) thereby making compensation image capture
impossible. For such slides, use an empty slide with coverslip to grab a compensation
image. If you select this, the software will not create new compensation images for each
slide. Compensation images are reference images used for white balancing and shading.
•
Save focus quality:
The measurement of focus quality (correctness of average focus on
layers) is saved. This option is inactive when
Extended focus
option is activated.
