The transparency in the images is based on the image transparency and not on the layer transparency. When you select a layer that appears transparent, 255 is returned because the layers transparency is 255 but the images transparency is 0. I can successfully set and get a layers transparency in a demo I will be sending you.
As best as I can determine there is nothing wrong with the code that gets or sets a layers transparency and the correct values are reported.
Description Set the overall transparency of the layer in the range from 0 (fully transparent) to 255 (totally opaque). Use Opacity instead of Transparency when the image has an alpha channel.
Description Set the overall opacity of the layer in the range from 0 (fully transparent) to 1.0 (totally opaque). Use Opacity instead of Transparency when the image has an alpha channel.
I have no idea why Fabrizio says to use Opacity instead of Transparency when the image has an alpha channel.
Maybe Nigel or Fabrizio can explain in more detail.
I am waiting for Fabrizio or Nigel to give more detailed information and the reasons for doing this as this change is breaking my olde code completely.
And time is running out for a rewrite at this stage.
I am attaching a sample PSD file for checking.
This file has three layers and each layer's Opacity is set differently.
I have also applied layer mask to one Layer and have also saved an Alpha channel.
In spite of all these I always get Transparency as 255 so from where does ImageEn read transparency value and what are its actual use?
