Flood selection tool, cannot select white in my image

[tammie1983]

I'm having issues with the Flood Selection Tool in the Pixel Persona.

I'm taking a class in surface pattern design, and had to upload an image then use the Threshold option to make it how you see in Image 1.

In Image 2 I'm go into the Pixel Persona, select the Flood Selection Tool, deselect Contiguous in the top menu, then select the white in the image. I've zoomed in as you can see so that I only select white. The image starts to move and then I'm supposed to hit the trash can, which is supposed to remove the white (I'm told in my class video that I'll see the image change in the layers panel).

The trash can doesn't seem to do anything, so I tried three-finger swipe and pressed delete in the menu that pops up. Nothing changes in the image in the layers panel.

The next step is to go back to the Designer Persona, pick a colour other than white or black, create a new vector layer, place this under the pixel layer, then draw a rectangle across the image and the white is supposed to change to the colour. However as you can see in Image 3, the black is changing to the colour I picked, not the white.

I've been back and forth with someone from the class but they've just told me to keep trying again. I've tried 5 or 6 times now with no luck.

Am I doing something wrong, is the class taught wrong or is there a bug?

I'm new to Designer and my class is being taught in V1 so it's been a struggle as it is.

It's hard to be sure what layer you have selected (none appear to be selected in your screenshots that include the Layers studio). However, your lowest layer (Photo.jpg) is an Image layer, not a Pixel layer. In order to work with its pixels, you will need to Rasterize it.

Hi Walt, I created Layer1 which is under the Pixel layer in order to draw the rectangle. Before that I was working on the Pixel layer - in my class we're told to turn off the Threshold Adjustment layer and Photo.jpg layer (I think I can just make out they're greyed out in Image2).

In the class there's nothing about rasterizing anything, but the class is taught in V1 if that makes a difference.

No, if you're working in the Pixel layer no rasterization should be needed.

But how did you get a pattern into the Pixel layer? And what rectangle are you talking about? I do not see a rectangle in the Layers studio.

I'm missing something in your workflow.

Hi Tammie1983,

I've just followed your tutorial video posted and found no issues in v2, perhaps your document does not have a transparent background, this would mean that any deleted pixels on your selected layer would show as white.

Hi Lee,

I think I've managed to sort it. It seems hitting the trash can and then swiping down and hitting delete invalidated the delete action. The trash can (as taught in the video) doesn't do anything, but swiping down and then hitting delete does. Not doing both.

No, the document doesn't have a transparent background, I do remember not selecting that as it wasn't mentionned in the original video before that one when creating the image.
