`mode`

48.

The name of the mode of the transition. There are three groups of modes: wipes, slides, and other. This can also be "custom", to allow a custom mode to be defined.

49.

In a wipe, the image stays fixed, and more of it is revealed as the transition progresses. For example, in "wiperight", a wipe from left to right, first the left edge of the image is revealed at the left edge of the screen, then the center of the image, and finally the right side of the image at the right of the screen. Other supported wipes are "wipeleft", "wipedown", and "wipeup".

50.

In a slide, the image moves. So in a "slideright", the right edge of the image starts at the left edge of the screen, and moves to the right as the transition progresses. Other slides are "slideleft", "slidedown", and "slideup".

51.

There are also slideaways, in which the old image moves on top of the new image. Slideaways include "slideawayright", "slideawayleft", "slideawayup", and "slideawaydown".

52.

We also support a rectangular iris in with "irisin" and a rectangular iris out with "irisout".

53.

The following parameters are only respected if the mode is "custom". Positions are relative to the size of the screen, while the crops are relative to the size of the image. So a crop of (0.25, 0.0, 0.5, 1.0) takes the middle half of an image.
