Use of .png files in Photoshop

  • May 30, 2011

I use Fireworks to create graphics using layers with each element on its own layer.

When I send them to some companies, they state that a .png file cannot be edited by photoshop, and that the file has only one layer.

Can anyone answer a few questions about .png and Photoshop?

1. Can Photoshop read and edit .png files?

If so,

          a. Must the layers be unlocked for them to be read as individual layers?

          b. When they have been edited in Photoshop, can they still have seperate layers that can be read in Fireworks?

All help would be appreciated.

    I didn't think the PNG format had the capability to carry layers, though I'm no expert on that format.  There is certainly almost no mention of the word "layer" in the format specification on a quick look...  Your best bet would be to see if Chris Cox (of Adobe) will comment on this tomorrow (Edit:  HAH!  He beat me to it).

    That said, there's an alpha channel that is interpreted by Photoshop as transparency. Photoshop can read and write PNG files with transparency.  I've just never seen any evidence that it can handle anything like layers with PNGs.

    Can you use the PSD format for transfers of multi-layer documents between apps?  That would seem be more likely to be properly handled.

    Photoshop reads and edits PNG files just fine.

    But PNG files do not normally contain layers.  Fireworks puts layer data in a private chunk inside PNG - and other applications cannot edit the Fireworks data.  When you open a Fireworks PNG with layer data in Photoshop, Photoshop will warn you that the layer data is being discarded.

    If you want to edit layer data, save the file as PSD/PSB, TIFF, or PDF with Photoshop layer data.

    Its not a .png file if opened in Fireworks, as it only has a single bitmap image in it.

    .png files as I understand them have layers for each item, so the text is on one layer, bitmaps are on another and none bitmaps such as circles have a layer each, and all you need to do to edit an item is to click on it and Fireworks will automatically select a suitable tool to edit the item. So whatever our friend above is using to edit it, its not Fireworks.

    Unless someone else knows better?
