Need help with alpha inheriting in A. Photo


Recommended Posts

Hi there!

I'm working in collaboration with a guy who uses PS.

The idea is as follow:

alpha.thumb.png.224a3ff094ea1e0f84869a9fe2a6b36d.png

I have "SALE" image with transparent background and I must combine it with a fill layer set to multiply so that the layer color will "drive" the "SALE" color.

I think this is called alpha inherit.

The PS guy did this in PS and I can open it in AP. It looks like this:

I've tried dragging layers, moving inside, and so on, and I can't make it work!

I can do this by duplicating "SALE" and using it as the alpha of the fill (drag it on top of the fill)

but for this project specific purposes I have to respect the layer hierarchy as in the example above.

This one:

Any ideas?

Thanks!

Hi,

when i understand this right, it should be simple in Photo:

  1. put the layer with text as bottom layer
  2. but a fill layer with the color on top
  3. Set the blend mode of the fill layer to "multiply"
  4. Nest fill layer to "sale" layer (by moving it and offering to layer name)

Thank you for your input NotMyFault.

It's not that easy though. I think I left out an important piece of information.

This is a small part of a bigger layer hierarchy:

So, this must be "nested" so the cyan fill layer don't affect the layers underneath.

Because if how the project is organized, these layers must be exactly like this

Could you upload the file, or at least copy the BG color and a few example "frame <x>" into a new file and upload it?

Sorry, I was already off by the time you posted.

Here's the file imported from PSD which has the "nesting" I'm trying to replicate in AP:

Sale - PSD import.afphoto

This is the "nesting" I'm talking about:

AP can open this and it's working as intended, so it makes sense I can recreate this.

Next, it's the file I've created in AP. I can get to the same end result, it's easy, but I have to get the same structure as in the file imported from PS:

Sale.afphoto

As you can see, I 've done this by isolating the SALE and the fill layer inside a group and using SALE as the transparency mask.

This works, of course, but for this project specifications it should be the same layer structure as the imported PSD.

The difference: your “sale” is still an image layer. Once you rasterize it to a pixel layer, Photo works identical as PS (nesting the fill layer affects only sale). Image layers are treated different than pixel layers.
