"No Pixels Selected"

Why do I get the message "no pixels selected"? I make sure the layer I want is unlocked and highlighted. I select all and "inverse" is dark, so I may select it, but when I try I get the message "no pixels selected". I have tried all manner of searches and notes on the internet, but haven't been able to find this issue. I want to inverse the image I have which is black and white photo. I also would like to apply a screen to make it look better. I find the Color Halftone selection, but I don't want a color halftone, I want a black and white one. I have searched using "black & white halftone, photoshop" and haven't found how to do it. I've learned a lot of stuff, but not what I need. I have more questions about RIP, but as that seems to be something the printer does, not the app, I'll put that aside until I figure out "inverse" and halftone. Thanks to any and all who can help me. I'm sure I'm missing a step. (I've done it in the past, I just cannot figure out why I can't do it now.)

Hi,
If you just want to inverse the photo (layer), press Ctrl+I (cmd+i) or go to Edit>Adjustments>Invert
(no selection needed)

Why do I get a "no pixels selected" when making adjustments in a new layer?

What am I doing wrong? I want to modify or replace the color in a selection, so I make the selection, create a new layer, and try to replace the color from the Enhance menu. I get the message " can't do it because no pixels are selected." The selection is OK; I can see the marching ants. The same happens when I try other color adjustments and probably other adjustments as well. Would appreciate some help. Many thanks.

Sounds like you have an empty layer selected.
Even if you have a selection established (showing the marching ants), your creation of a New Layer means that your selection is now on that new layer, which is empty, and thus there are no pixels selected to modify.
Try skipping the New Layer step.
Or, duplicate the layer you want to work on, then do the selection, then the adjustment.

Pixels & Selection Tools

In Elements 12 I keep getting the dialog "No pixels are selected" or "No pixels are more than 50% selected" when trying to use any of the selection tools and some of the other tools as well. What can I do to correct this problem please?

Hi, Thanks for your reply, I'm quite new to Photoshop so not too sure about of the technicalities. I've tried it on the background layer, background copy and ordinary layer with the same results, not too sure what you meen by active layer. Regards

Make sure that you are working on an active layer that has information, not a blank layer or an adjustment layer.

Suppress Warning, no Pixel selected

Hello,
is it able to suppress the Warning - No Pixel selected?
The warning pops up when I select the lasso tool in subtract from selection mode and I subtract everything. Problem is, since this warning occurs not during a script, I'm not able to use "app.displayDialogs = DialogModes.NO;"
Is there a way to generaly suppress this warning?
Thx in advance
Joerg

Hello and sorry for my late response, I was busy with other stuff.
However the problem still exists.
I'll try to describe what the script does, hopefully you will read this after all this time:
1. Coworker/-s mark an area with the lasso tool and fill it with a color all on one layer (the area of a painting with a tear for example)
2. If parts of the tear on the real painting are fixed, coworkers press an action button and the area (tear) in photoshop is selected. (area is surrounded)
3. Then the lasso-tool is selected in subtract from selection mode and the coworker subtracts the fixed parts of the tear - area
4. The fixed parts getting deleted from that area
That all works fine, the only problem is if the whole area is fixed, everything gotta be subtracted from selection and then the warning pops up.
This is just a very rudimentary description but thats basicly what the script does.
thx in advance!

Preview.app - pixel selection dimensions are back!

Here's another of Snow Leopard's little unreported fixes.
I asked a question in the "Using Mac OS X Leopard forum" back in January 2008:
"In Tiger (OS X 10.4), when I wanted to crop an image in Preview, I would make a rectangular selection by clicking and dragging. If I held down the Option key while doing so, a little window would appear next to my cursor that displayed the pixel dimensions of the selected area. This allowed me to adjust the selection to precisely the size I wanted, which was very useful. However, in Leopard (OS X 10.5), this feature seems to have disappeared. I hold down the Option key but that little selection dimension display doesn't show. Did Preview lose a feature in the Leopard upgrade, or am I doing something wrong?"
In Snow Leopard, this feature has been reinstated and appears to behave the same as it did in Tiger. Hooray! Thanks for listening, Apple!

Sounds great -- but is that possible?
Sure is. I just launched the Tiger Preview, and it is still working in 10.5.2 (and you can still constrain to a square by holding down the Shift key). See the directions in this thread:
http://discussions.apple.com/thread.jspa?messageID=5889735
If you have a problem, see my reply near the bottom. I needed to do one more step than the original hint to get it to work for me.

'Cut to new layer' function for pixel selection.

hey guys. This is a pretty minor feature, but it might be handy.
The feature would be a single comand that could remove pixels from one layer and paste them into a new layer.
CTL-X technically does this, but since CTL-X clears the selection, the paste has no guide in order paste the pixels into the same location.
CTL-C, DEL, CTL-V , has the effect of cutting pixels from one layer into a new layer while preserving the selection, but it would be nice to have as a single command.
The obvious shoice would be CTL-SHIFT-X, but that's liquify, and I like it there.
So, I propose ALT-SHIFT-X. I know that the alt-shift combination is never ever used, but honestly, it's not a really importnant feature either
Thanks for reading.

Already there - control J (new layer via copy) and control Shift J (new layer via cut) - which is exactly what you have asked for. To redload the selection you can simply control click the new layer - mostly you WOULDN'T want to do this, since it just gets in the way. You could reassign them if you wanted.
Do you seriously think that photoshop version 11- wouldn't have this shortcut by now? These ones were there back in 4 or 5 at least

Pixel "selection" algorithm

I am trying to write an algorithm that operates on a 2-bit (Black and white) image. Given a black pixel, it needs to be able to find all other black pixels that are directly connected to it, or indirectly connected to it (connected to it by being connected to another pixel that is directly connected to it, however many levels deep). (If you have ever used photoshop before, I am basically refering to the idea of a very simplified magic wand selection tool) I currently have this method implemented recursively, it traverses through the pixels as though they were a tree structure, which works for smaller images, but for larger images (longer paths to traverse) it gets a stack overflow. Does anyone know of any algorithms that would preform this kind of a task?

It is fairly easy to convert a recursive "connected-components" algorithm to an iterative one. You just have to maintain your own stack (Use one of the List implementations in java.util)
Remember that the pathological case for a recursive connected components algorithm results in the depth of recursion equaling the number of pixels in the image.

How do I specify exact corners with the rectangular selection tool?

Suppose I have an image 2000 pixels wide by 1000 pixels high. Pixel (0,0) is at the top left as you view the image. Using the rectangular selection tool, how can I specify an exact area to select? Say, for example, I want to select the area defined by (0,0), (100,0), (100,100) & (0,100), how would I do this?
I'm using Photoshop CS6 on a Mac with OSX 10.8.3.
Any help is appreciated.
Thanks,
Kevin H.

Mylenium,
33,406 posts! That's amazing. Thanks for your technique for specifying an exact selection size. I tried it out and it works, but is there a way to get the marquee to snap to the guides, as opposed to snapping to pixels. I can't quite get the marquee to fall exactly where I place the guides, at least not easily.
Here's a method I've come up with since posting my question. (I guess I should have tried harder to figure this out before asking the question.)
Figure out beforehand where you want the corners of the selection marquee to be.
Activate the rulers: View>Rulers or (Cmd-R.)
Set rulers to pixels: Photoshop>Preferences>Units&Rulers>Rulers>Pixels
Select the rectangular selection tool.
In the menu bar for the selection tool choose Style>Fixed Size. Then in the dimension boxes to the right of the Style button, type in the width and height you want for your selection, e.g. 200 by 100 pixels.
Zoom in on where you want the top left pixel of your selection to be. Zoom in enough to clearly see the pixel.
With the selection tool active, click-and-release on the pixel you have zoomed in on.
Go back to normal view (Cmd-0) and you should see your entire selection.
This answers my own question, and with your method I now have two ways to do this.
Thanks,
Kevin H.

Is it possible to lock guides to each other? Or make selections based on guides??

Hi,
I am curious if there is a way to lock guides to one another. By this I mean: lets say I have a guide at 10px down and another at 20px. I am looking for a way to lock them, so if I move the first guide down 5px the second guide will move with it and continue to maintain the 10px gap.
Also I am wondering if there is a way to make selections based on guides. For example, I want to make a selection that starts at the top guide and goes to the bottom guide.
Thanks to anyone that can help!
G

There is no way to link guides directly. Here are some guide tips for you which may help…
• Setting the ruler increment can be done by control clicking (yes control) on the rulers themselves,
• Holding down the SHIFT key while dragging guide lines will snap those guides to ruler increments. So if you have pixels selected as the increment as in the tip above you can easily snap quides to 10 pixel steps. Where the guides will snap (how fine the increment) is dependant on how close you are zoomed.
• As Christoph has said, you can snap to Guides - so in your example a 10 pixel marquee selection, definable in the marquee tool options bar (fixed size) can easily be snapped to a guide, and then another guide can be snapped to that. With the move tool active this is a very easy process

How to select a small area without a low feather???

When i select a small area with the lasso tool i get the warning: 'no pixels are more than 50% selected. The selected edge will not be visible.'
I already read that the feather should me low. However if i do that, the outcome wont be nice.
I want to bleach teeth and when i use a small feather the teeth wont be selected very well. So how can i solve this problem??
(I am sorry if my english is not that well, i am from the Netherlands )
I hope someone can help me with this.
greetings stephanie

You can use the lasso tool without any Feather (set feather to 0) keep anti-alias checked and use Refine Edge to add any feathering if needed.
You might make a layer mask from the selection and then use the brush tool to refine the mask.
When you get that message you still have a selection, but elements is letting you know that any pixels selected less than 50% won't be visible with the marching ants. (the selection edge you see
when using any of the selection tools)
What version of photoshop elements are you using?

Magnetic lasso problems and pixels

When using the magnetic lasso and when I create circle around figure, it goes back to lasso and does not go around whole figure for me to move. Also every time I lasso something, the little ants are around it, but I keep getting a error message that it could not complete the copy command because no pixels selected.. Need to solve the problem with lasso, then problem with the error message for no pixels selected next. Would appreciate any help you could give me. I am running PSE13 on my PC.
Trying to cut figure out of one pic and placing in another pic or background.
Would also like to know why any picture I bring out of the photo bin to work on goes immediately to the background even if I got it locked and the oirginal backgroud picture disappears.
HELP!

I have done everything you said, completed my magnetic lasso around figure, as soon as I meet and click, the lasso disappears. Yesterday when I did it and little ants moving around and let go of my mouse it changed to plain lasso inside of picture of the person but was no way to the outside and ants were still running. This morning did as you said and still problem, I tried using a brush to circle it and the ants were running just like supposed to, but when I followed your instructions edit-copy, edit-paste, I still always get the message when I click copy----Could not complete copy command because no pixels are selected every time. I have connected the loop and the little ants are still running (probably getting their little feet tired by now) and still get that error as above. Can't seem to get past that copy stage, what am I doing wrong?????
Thanks for your help in advance.

You have to navigate completely around the object that you are selecting, so that you close the loop. You can backtrack as you go along with the delete key on the keyboard, and also set additional anchor points with a left click. I find it helpful to increase the contrast, if necessary, before starting with the tool.
  .Trying to cut figure out of one pic and placing in another pic or background.
Try this
   - Open picture B, the one you wish to select something from to add to another picture.
   - Use one of the selection tools, e.g. selection brush, lasso tool, to select the object. You will see an outline ("marching ants") once the selection is complete
   - Go to Edit menu>copy to copy the selection to the clipboard
   - Open picture A, then go to Edit>paste
   - Use the move tool to position object from picture B.
   - In the layers palette you should see picture A as the background layer, and object B on a separate layer.

Histogram giving too many pixels

I am using photoshop to design rugs and i have to get an accurate percentage for each colour used in the design so that the rug makers can dye the correct amounts of wool.
I am simply converting the image to indexed colour and making sure that if it is a three colour rug there are only three indexed colours in the design.
then i am selecting colours using the magic wand and working working out from the histogram what percentage of the image this colour is by dividing the number of pixels selected ,by the noncontiguous non anti aliased magic wand, by the total pixels in the image.
most of the time this is working fine, but sometimes one area of colour will clearly be read as having far too many pixels, sometimes even more pixels than are read in the image as a whole.
I don't understand why this is happening, there are no layers in the image, surely this should be really straightforward?
please help!

If you want to give a Script a try, paste the following text into a new file in ExtendScript Toolkit (part of Photoshop’s installation, Applications/Utilities/Adobe Utilities/ExtendScript Toolkit CS4 or /Applications/Utilities/Adobe Utilities-CS5/ExtendScript Toolkit CS5) and save it as a jsx-file into Photoshop’s Presets/Scripts-folder.
After restarting Photoshop the Script should be available under File > Scripts and can be assigned a Keyboard Shortcut directly, recorded into an Action, (in CS4 and CS5) be used in a Configurator-Panel or started from ExtendScript Toolkit directly.
Edit: Quickmask might be a better way to avoid crowding the History, so I’m changing the code.
// alert of percentage of selected pixels relative to whole image, but only if selection is strictly black/white;
// 2011, use it at your own risk;
#target photoshop
if (app.documents.length > 0) {
var myDocument = app.activeDocument;
// from function hasSelection(doc) by xbytor;
var res = false;
var as = myDocument.activeHistoryState;
myDocument.selection.deselect();
if (as != myDocument.activeHistoryState) {
res = true;
myDocument.activeHistoryState = as;
if (res == true) {
// set to pixels;
var originalRulerUnits = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS;
// get quickmask’s histogram for 0 and 255;
myDocument.quickMaskMode = true;
var theChannel = myDocument.channels[myDocument.channels.length - 1];
var white = theChannel.histogram[255];
var black = theChannel.histogram[0];
var total = myDocument.width * myDocument.height;
myDocument.activeHistoryState = myDocument.historyStates[myDocument.historyStates.length - 2];
if (white + black == total) {
alert ((white/total*100)+" percent\nselected pixels: "+white+" \nunselected pixels: "+black)
else {
alert ("the selections seems to be anti-aliased")
// reset;
app.preferences.rulerUnits = originalRulerUnits;

Select color does not seem to work in 2014.2on my mac. I don't understand what I am supposed to change in preferences

I see there are references to select color not working on the mac. Mine does not seem to work but I think it did when I first downloaded. There is some discussion of changing preferences... In what way?

Photoshop. 2014.2.2release.
or 20141204 . r.310.x64
MacBook Pro The ye dropper should be able to select a given color and find it throughout the image. And it should be adjustable to select colors that are related. I am only getting a "no pixels selected" error message. Even if there is one layer.

CS3 Photoshop - Canvas resize anchor grid not selectable anymore. What happened?

Hi,
I have Version 10.0.1 and up to two days ago I could select resize canvas, change the pixels, select the appropriate anchor and all went well. Now, for some reason I can no longer select an anchor point. Absolutely nothing happens if I click on one of the arrows.
I have checked Image mode and it is RGB 8bit. I have gone through all of the settings I can think of and no luck.
I cannot remember making any change that would affect this function but apparently I did. I doubt the program just decided to quit. My OS is XP Pro but that hasn't changed. Nothing has that I can think of
Does anyone have any idea what I need to do to get this to function again?

Reset your preferences
Hold down CTRL + SHIFT + ALT keys then start photoshop. Window pops up choose yes.
