Questions tagged [perspective]

In Eclipse, a perspective defines the initial set and layout of views in the Workbench window. In CSS, perspective is a property and concept used in 3D transforms.

In Eclipse, a perspective defines the initial set and layout of views in the Workbench window. Within the window, each perspective shares the same set of editors. Each perspective provides a set of functionality aimed at accomplishing a specific type of task or works with specific types of resources. Perspectives control what appears in certain menus and toolbars. They define visible action sets, which you can change to customize a perspective. You can save a perspective that you build in this manner, making your own custom perspective that you can open again later.

In CSS, the perspective property determines the distance between the user and the z=0 plane, affecting the amount of distortion caused by 3D transforms. The perspective-origin property is related.

How do I turn off "Automatically Switch to Debug Perspective" mode in eclipse?

Is there a way to turn off this mode? I must have clicked it by accident, and now it's getting really annoying. I've looked in the preferences and perspectives pane, but can't see anything. Does anyone know where this option is configured?

PIL's Image.transform has a perspective-mode which requires an 8-tuple of data but I can't figure out how to convert let's say a right tilt of 30 degrees to that tuple. Can anyone explain it?
