Something I can't wrap my head around... there are certain graphics that I open in Affinity Photo, say a JPEG or something that I downloaded off the internet, and I'm trying to use the Flood Select tool but every attempted click yields no selection. I even checked the online tutorials to figure out what I was doing wrong, and it looked like I was doing it right. It just wasn't working.

Completely at random, I right-clicked on the image in the Layers panel and wondered what Rasterize did (didn't make sense to me). The layer now said (pixel) after the name. Now when I tried Flood Select again, it worked.

So my question is, 1) why won't the Flood Select tool just work right off the bat and 2) why do I have to "rasterize" an image that is already raster? Perhaps they've used the wrong term here?

Just another confusing Affinity element... slowly learning here. :)

doesn't seem to be any dramas or differences with the flood section tool on my computer . I have been caught out in the past with tolerance too low 
Rasterizing: I will leave that for experts

@Jeremy Bohn,

While images are raster images, when they are placed into AP, by using the File>Place command or Drag and Drop, they can not be altered until they are Rasterized to a Pixel layer. I really don't know why, but it's how they designed the program. One reason for this is an image layer will retain the native resolution. You can scale an image layer down and back up and not suffer a loss in resolution. To see this, place an image, scale it way down so it's very small. Then right-click on it in the layer's panel and rasterize it while it's small. Now scale it up. So long as the image remains an image Layer this doesn't happen, but you can not alter the pixels  Here's the AP on-line Help for Placing an Image.

The Flood Select tool is very sensitive. When you click-drag with it, the tolerance is automatically adjusted. Watch the tolerance box while dragging to see this. It took me a while to be able to use it. I'll drag a little then stop, then drag a little more. Also, it makes a difference on what you're needing to be selected if contiguous needs checked.

You should not click-drag it. Only click.

According to the Help file,

Quote

The Flood Select Tool enables you to select pixels of a similar color.

Pixels added to a selection are determined by the color of the pixel or adjacent pixels under the tool when you click or drag across the page, respectively. The dragging operation controls the selection tolerance, i.e. how much the selection will grow to encompass pixels of similar color values under the cursor.

Just noticed, according to the tooltip in the bottom left corner states to RightMouse Click to Add. This is not working for me.

Did you Open them, or did you copy/paste or drag onto an already opened document?

It makes a difference.

Thanks Ron. Once I get the Flood Select actually working, I've figured out how to use it. I just don't get that first extra step when I open a non-Affinity image. This last time that it happened, I knew there was something I did to get it working in the past and I could not figure it out for awhile. I guess I just don't get it - why bring an image into Photo if not to edit it, so why not "raster" it automatically or maybe even just ask me. I newbie might just give up and think it's broken. And I still think raster is the wrong word.

Open them. In one case, opened it, selected the layer and copied then pasted into an Affinity Photo file, and still needed to "rasterize" it.

Another helpful idea: instead of letting me click on the Image layer with an unsupported tool over and over like and idiot, wondering why it's not working, the app could just throw up a warning saying the selected tool is not supported with that type of layer and to convert to a Pixel layer?

Exactly the same question bothers me. I do not understand what's the point  to import of bitmaps as objects (image) by default. What's sense it is? By default, it should be imported as (pixel).

Image layers in Publisher can be embedded or linked, and they preserve many of the details of the original files.  Many people prefer to link their images instead of embedding them, but that is not possible with pixel layers.  Image layers also support a "non-destructive" workflow and allow re-developing RAW data in Photo when working with RAW images.

Pixel layers are more like the layers in Photoshop or other traditional photo programs.  They contain a copy of the raster image data in a format that can be edited.  They lose the connection back to the original file.

I think the point is that for a new user there is no indication of the layer difference and what they actually are. This is especially true for the Photo app, especially people who are coming from Photoshop and are expecting a Photoshop-like experience. I'd wage most Photoshop users would have little use for the default behaviour or be aware of the format differences (since Affinity files can be exchanged between the apps). Like myself, they'd find it confusing, assume it's a broken, buggy program and stop using it in frustration. This is exactly what I did last year.

This is why Photo needs to be more clear of the layer type difference or per my suggestion, explain why a certain tool is having no affect. Or maybe have an option to convert a non-Affinity graphic to a pixel layer once opened?

Photoshop has a similar concept to Image Layers and one may also link or embed files. One still may create selections, duplicate portions or sample colours from this sort of content. The Image Layer implementation is a needless trap as partial rasterization could take place on the fly.

Totally agree with Jeremy.  Really quite simple things are made frustrating nightmares by such confusions. It's the lack of feedback that is the problem.  But Affinity's pluses ("forcing" you to work with adjustment layers , the preview features, general efficiency etc.) mean it's worth  persevering.

Much of the confusion comes from the assumption that Affinity Photo is going to provide more of a "Photoshop-like experience" than it actually does. Avoid making that false assumption, take a little time to learn how it differs from PS (& why), & most of the frustrations should vanish.
