[BUG-8328] [MAINT-RC] Very jagged pictures created by the snapshot floater #15944

Open sl-service-account opened 9 years ago

sl-service-account commented 9 years ago

Steps to Reproduce

Actual Behavior

The saved picture has jaggedness all around that was also shown in the preview shot before the picture was saved. The antialiasing setting in the viewer appears to have no effect on the produced picture either. Even pictures taken with the antialiasing set to 8x are very jagged. See the attached screenshot. This does not reproduce on the current official release 3.7.24.

Expected Behavior

The snapshot floater should not be saving very jagged pictures.

This is caused by using the nearest neighbor interpolation introduced in http://hg.secondlife.com/viewer-bear/commits/fd3a4d5c2cf5b52d9b678bac2e2f02168bcd46f3
