Card Wipe effect

This effect simulates a group of cards displaying a picture and then flipping to display another picture. Card Wipe
provides control over the number of rows and columns of cards, the flip direction, and the transition direction
(including the ability to use a gradient to determine flip order). You can also control randomness and jitter to make
the effect appear more realistic. By varying the rows and columns, you can also create venetian blind and Chinese
lantern effects.
This effect works with 8-bpc color.
Original (left) and after applying the Card Wipe effect (center and right)
Adjust the following controls for the Card Wipe effect:
Specifies how far along you are in the transition. A setting of 100% displays the new image

Transition Completion

revealed by the transition; a setting of 0% displays the original image.
To create an animated transition, animate this value from 0% to 100%.
Specifies the width of the area that is actively changing from the original to the new image.

Transition Width

Specifies the image to be revealed by the transition. You can use any file in the composition (its visibility
Back Layer
can be turned off). If the image has an effect or mask applied, precompose the layer first.
Specifies the interaction of the numbers of rows and columns. Independent makes both the Rows
Rows & Columns
and Columns sliders active. Columns Follows Rows makes only the Rows slider active. When you choose this option,
the number of columns is always the same as the number of rows.
Defines the number of rows up to 1,000.
Rows
Determines the number of columns up to 1,000, unless Columns Follows Rows is selected.
Columns
Note: Rows and columns are always evenly distributed across a layer, so odd-shaped rectangular tiles don't appear along
the edges of a layer, unless you are using an alpha channel.
Specifies the size of the cards. A value smaller than 1 scales down the cards, causing transparent grid lines
Card Scale
to appear between them. A value greater than 1 scales up the cards. Oversized cards create a blocky mosaic effect as
they overlap each other from lower left to upper right. During the transition, the jumbo cards actually pass through
one another.
