This plugin crops or enlarges the image. It takes 4 values as input, a
|
||
|
|
top, bottom, left and right offset. Positive values will crop that much
|
||
|
|
pixels from the respective border of the image, negative values will add
|
||
|
|
that much pixels. When pixels are added, you can specify their color.
|
||
|
|
Some predefined colors are usable with an enum property.

|
|
other properties, alpha and border_alpha can be used to set the alpha
|
||
|
|
values of the inner picture and the border respectively. an alpha value of
|
||
|
|
0.0 means total transparency, 1.0 is opaque.
