How to deal with projection image distortion?

When there is a projection angle between the projector and the projection surface, the projection image will distort.

Sometimes, clients have designer making adjustment on the artwork. But some clients don't have the alibility or sources, we can help them to pre-distort the image on the gobo to correct. At this time, we need clients to provide below data:

1. The height of projector installation place.

2. The projection distance between projector and projection surface.

3. The image size wanted to get.

4. Vector file or high resolution artwork.

Then our engineers can calculate to help.
By the way, this only could work for round shape projection image, for other shape projection images like rectangle, this calculation cannot work.
