Selection from flood tool, delete deletes everything?

[ahnay]

I dont know whats happening.  I used it earlier today to delete the white backgrounds from the holly image and am just trying to do the same for the branch image.  But every time i hit the delete key it deletes everything, instead of only deleting the selection?  

im sure its a simple fix, thanks

You're working with Image layers, as you can see from the (Image) label in the Layers panel. You need to Rasterize the layer before you can work with its pixels. Right-click and choose Rastermite  Rasterize, or use the Layer menu.

Thank you.  i will do this next time.  i wonder how i did it the first time? scratches head..  i managed to get it done, i put it in a new document and it worked fine.  I saw in a video that the guy only had one image he was working with.  But really, that was just a workaround

There is a good chance that you were working with a Pixel Layer rather than an Image Layer.
When you open an image, rather than placing an image into a document, you will get a Pixel layer by default.

Is that a bit like Vegemite?
