PictureEffects Xojo and Real Studio Plugin

BrightnessEffect.ApplyInPlace Method

Applies the effect in place on a given 32 bit source image with a given 32 bit mask.

ApplyInPlace(
   source as Picture,
   value as Integer,
   mask as Picture)

Parameters

source
The image to manipulate.
value
This value specifies how much brightness to add or subtract from the picture.
The value can be from -255 to 255. Values out of this range will make the function fail.
mask
To limit the filtering to certain pixels then set a picture defining the mask to this parameter. Pass nil to this parameter if the filtering should not be limited to certain pixels.

The mask picture must be a 32 bit picture and must be same size as the src picture. If the mask picture is not 32 bits and same size as the src picture then the function will fail and leave the result picture unchanged.

Remarks

Do not use this to attempt to modify constant images that should not be changed. Constant images are for example images embedded into the project.
