Area Image Magic Wand Example

I would like to use the example of labview "Magic Wand Example" to calculate the area that was selected.
How could I do that.
Thank you.
Eliel

I was able to measure the area in pixels but how can i do measure in cm ²?
What should I do to turn PIXEL in AREA (cm ²)
Thank you

Photoshop CS6 Magic Wand

Hi,
When I select the area with magic wand tool and refilled, the edge of the selection is way rougher than before.
This is before refilled.
This is after refilled.
How can I fix this?

This is whole screen shot.
and this is the image size.
I'm quite interested in the story about alising.
Could you tell me what and how I improve this?

I am new to Photoshop CC. I am trying to use the magic wand to highlight a dull sky, and it is just making a weird selection that has nothing to do with my photo

I am trying to use the Magic Wand to highlight a dull sky so that I can add something more interesting.
When I try to isolate this area, the magic wand seems to just make a random selection throughout my photo.
I have anit-alias on, and my tolerance is at 5.

First, is the layer containing the photo of the sky selected? That might help.
But there are probably better ways to make selections than the magic wand, depending on the value ranges in the sky you wish to select.
Try Color Range, Quick Mask, or manual selections using the Polygon Lasso Tool, or combinations of all of the above.
You can also paint your selection on an additional layer (using brushes), and convert the painted area to a selection, make a channel of that selection, and refine manually.

Is it possible to find and retrieve the pixel coordinates of a polygon image? Perhaps using Magic Wand and Paths?

THANK YOU!

Hi Mylenium,
I want to create a complicated polygonal hotspot around the map of many countries of the world in Dreamweaver (eg. a hotspot around the US border), but don't want to spend the time tediously selecting the coordinates around the border.
i.e. the code in Dreamweaver would be something like this
<area shape="poly" coords="5,343,18,340,38,327,71,314,88,304,75,302,63,301,46,301,58,290,58,284,40,292,36,28 1,43,276,47,263,62,257,91,244,99,244,113,237,132,235,146,226,155,222,131,221,102,223,106,2 06,151,197,153,202,164,203,178,198,187,198,181,189,176,187,170,173,185,166,209,162,229,154 ,253,146,280,143,307,142,321,136,354,143,374,145,404,150,429,149,440,155,314,259,304,268,2 94,276,302,281,310,278,308,288,311,296,328,292,338,284,342,290,340,296,341,310,335,325,342 ,335,346,341,342,345,333,351,327,357,321,343,324,340,316,323,321,318,318,306,307,307,298,2 87,274,282,252,280,238,272,236,268,212,273,209,283,164,294,187,274,132,295,128,301,32,338, 18,346" href="/UnitedStates.html"
Is there a way to use Photoshop's magic wand tool / slice / path tool to extract the coordinates of an images border for me?
Thanks

Recommend an image editor that has a magic wand tool to delete white background and save as PNG with transparency

Hi Everybody,
I need an iPad app that can open an image and has a Magic Wand-type tool so I can select white background around a subject. Then delete the white areas so it becomes transparent. Then save as a PNG with transparency. I've tried Pixelmator...I can select the white but I can not delete the white. I downloaded Photoshop Express...no magic wand tool.
Does anyone have any recommendations?
Thanks,
Gary

It's a shame you don't have Mac. The feature is built in the system (in Preview, Pages, etc).
That makes me think: this feature should be in the iPad iWork apps too (Pages and keynote): check out this guide: http://www.cultofmac.com/256475/knock-out-those-backgrounds-instant-alpha-hidden -in-pages-for-ipad-ios-tips/

How to unselect magic wand tool to select another area?

This is so silly but it is driving me nuts. I used to be able to select an area with the Magic Wand tool and then when I was done, click on something else and it would "deselect." But now it doesn't do that anymore. Did I change a setting somehow by accident or did they do an update that changed that? I hate having to do Ctrl D to deselect it when I used to just click on something else.

Thanks for your help. I actually checked on the icons where you mentioned and the one I wanted was the "new selection box" I had "add to selection" checked and so it wouldn't unselect when I went to new area. So your answers helped! Thanks so much.

Coloring issues with magic wand tool and paint bucket tool, leaves uncolored areas near drawn lines

Photoshop CS6 doesn't color properly. Whetever I use brush tool or elliptical marquee tool to do the lines (with brush tool I use Hard Round, not soft), it doesn't color the whole area when i fill them with color. This happens with both magic wand tool AND paint bucket tool, there is always a small uncolored area near the lines. I have tolerance on 30, and anti-alias, contiguous and sample all layers boxes checked. (this setting worked on my old CS3) I have tried tolerance from 0 to 100, no difference. I have also tried unchecking the boxes I just mentioned, still no difference. I hope there is a solution for this, because it is tedious to always go to the Select - Modify - Expand every time I need to color some area. So how do I fix this problem? I use seperate layers for lines and colors, like I have always done with other Photoshop versions. Even in school where they have CS5 those normal settings work.

Hello Chris,
I don't think this is a "user error". I think Adobe should be able to program a state of the art paint bucket, which is capable to get this done right.
Other applications are able to get this done right.
Please don't fall into a programmer's ignorance ("this is done right by definition") but listen to us artists and improve this unintuitive behavior. Add something like "ignore transparent pixels", because this doesn't even work if you draw on an empty layer.
Thank you!

Content Aware with Magic Wand¿

I used to fill in gaps of missing Panos with content aware in CS5 using the magic wand and fill - content aware. In CS6 it fills it in with the foreground color. The only way I can get the content aware to work is if I make the selection with the lasso tool. The quick Sslection tool will not even select the area without pixels. Anyone else had this issue¿

Thank you for the reply. Yes I selected the content aware option in the drop down; I have been using the content aware to fill in gaps in panos for a long time now. The issue is in the CS6 Beta when I use the magic wand to select the empty pixels, and there are a lot in places, it will only fill it with a solid color. Also the quick select tool will not even select empty pixels. The pano I have isn't that large, 35090 px by 3490 px, not near the type of panos Ben Willmore does for example. I just wondered if anyone else has this issue and if so is there a fix.

Selecting pixels on a layer using the magic wand

PS CS5
I have been trying to select individual pixels around a shape on a layer to create a mask to hide the semi transparent pixels but i cant seem to select individual pixels to add to the selection.
In some places along the path of the object I have been able to select some individual pixels, but in other parts, groups of pixels automatically get selected or even the whole path is selected.
How do i control this? I want to be able to only select the pixels i choose and not groups.
The settings i am using are:
Tolerance = 0
Contiguous - Selected
Sample all layers - Selected
I have tried doing this with each of the following settings to no avail:
New Selection
Add to selection
Subtract selection
Intersect with Selection
I was following a tutorial on the lullabots website to create a mask but can't reproduce the steps because of this problem
http://www.lullabot.com/articles/creating-awesome-new-icon
thanks in advance

One setting that you haven't listed and which can affect the Magic Wand tool is the Sample Size.
Activate the Eyedropper Tool, then right-click somewhere on your image. Make the sample size Point Sample. This will then tell the Magic Wand or any other tool that does an "eyedropper sample" operation to use the value of the single pixel you click on to gauge its operation.
I mention this because the coupling is modal and sometimes overlooked.

Content-aware-fill and magic-wand-tool

Hello! I use the content-aware-fill to remove some text from a photo. To do so, I use the "Polygonal Lasso Tool", select the text with a generous border and click edit -> fill -> content-aware-fill.
This works fine, but selecting a text with the lasso-tool is very much work. So I tried to use the magic-wand-tool - some clicks and the text is selected, very fast and fine. No applying the content-aware-fill - the text vanishes somehow, but the borders of the text are still visible. I guess you really have to select the text AND some background around it to make content-aware-fill work. But isn't there a way to do this with the magic-wand-tool? Increasing the tolerance didn't work, I would need something like "magic-wand-tool and increase the selected area +20 pixels in all directions".
What procedure do you suggest?

Are you trying to remove a watermark that says something like "Proof" or "Copyright"? If so, you won't get much help here. The best advice in that case is to actually pay for the photo. It's surprising how many people ask for help doing illegal things.
Please confirm you are not trying to defeat someone's copyright (e.g., post a small part of the image), and I'm sure you'll get more help.

Clipping paths from magic wand selection

I've been looking through dozens of tutorials but even the one's that mention this they all assume you know how to do it. All I would like to do is turn a selection made using either the magic wand tool or the other selection tools/methods and turn that into a clipping path.
This is the selection i've made with the magic wand tool:
http://img414.imageshack.us/img414/9307/screen28qd.jpg
Also is their any way to turn a whole layers contents into clipping paths? For example I have that image on it's own layer with no background, could I turn everything on that layer into a clipping path?
Clipping paths for this kind of thing as far as i'm aware is the only way to import images into quarkxpress with no backgrounds.
thanks
sam

Hey Sam, if I'm not mistaken you simply have to make your selection, then select make "work path" from the Path window, next you save the path and then select "clipping path" from the Path window and select the saved path's name.
I would think this would work with layer selections as well.
Hope this helps...

Drag & Drop and Magic Wand and Any Selection Bug...

Helllo,
I am experiencing a continuous bug in Photoshop CC 2014.
First I'm on a Mac G5 using OSX version 10.8.5.
The bug I am experiencing is not allowing me to select anything using the Magic Wand tool or even the Arrow Selector in any layer if I drag and drop an image from the web to Photoshop.
I have to physically click on the Mac's main background window outside of Photoshop and then click back to Photoshop to get it to work.
Thanks,
JW

I am guessing you are using an ImageIcon to put the image into the JLabel. I would suggest creating your own version of "ImageIcon". In the interface Icon, the paintIcon method gives you access to the component which is your JLabel. You can get the size of this and draw the image to fit the components size. getIconHeight/Width() should work ok if you just return the initial size that you want the icon to be.
Another option is to extend JPanel and override its paint method. This would give you direct acces to paint whatever you want, and you can resize your image accordingly when the size changes.
As far as the flashing goes, you might want to post code (use [ code ] [ / code] tags). There might be something there that someone will see.

How do I select similarly colored text using the magic wand?

I converted a large document from RGB to CYMK (File | Document Color Mode). I'd like to select all of the text that was RGB(0,0,0) and is now CMYK(75.02,67.97,67.02,90.16) so I can change it to CMYK(0,0,0,100). I think the magic wand is the way to do this (correct me if I'm wrong).
I have text in a dozen or more text areas. Many of the text areas overflow text into another text area. Some of the text in the text areas is "black" but there is also text with other colors that I'd like to remain unchanged.
For example, I'd like to select all of the black text in the following two text areas without selecting the red text. I thought that I could click on the black text and have all the black text (but not the red text), selected, but the entire text box is selected (and nothing in the second text box is selected). Can the wand select some text within several text boxes? If not, how should I go about changing the black? Thanks.

Thanks Mylenium.
If I use the Same Fill command, it does select both text areas. But if I then choose a replacement color (e.g., CMYK(0,0,0,100)) all of the text in both text areas is changed to black (i.e., the red text in my above illustration also changes to black).

Using Magic Wand to select & enahance path in CS2

I have an aerial image in a .JPEG file which shows a GPS track/route. I would like to enhance/alter the appeareance of this track/route in the image. For example, I would like to possibly increase the thickness of the track/route, possibibly change the color and most importantly be able to change the appearance of the track/route to appear as a dashed or dotted line. I do not wish to change the size or shape of the track/route as it currently appears on the image. I am able to select this entire route using the Magic Wand tool but I am unable to further maninpulate it. Any suggestions on how to most efficiently achieve my desired goal(s)? I have thought about using Illustrator CS2 but it seems as though when using Illustrator there is no feasible way to select the track/route with the magic Wand tool like you can in Photoshop CS2.
See attached aerial image file which shows the GPS track/route.
Thanks!
Using Photoshop CS2 on a Windows PC

to increase the thickness, after you selected it, go to Select->Modify->Expand, make a new layer and with the selection still active, fill that layer with whatever color you want. Getting a pattern to follow that selection will be very hard to do though. You'd probably need to make a checkerboard brush, make a path that follows the red outline and then stroke that path with the brush you just made (make sure that the brush has a spacing of 100%)

Magic wand too sensitive

Recently upgraded to CS3 (from CS1) and suddenly I'm finding the magic wand tool worthless. It's way too sensitive. If I try to use it to select just the contiguous black part of my image, for instance, it's selecting almost the entire image, everything from black all the way to 50% values or less. This is with my tolerance setting at 2! It was never like this before.
Is there a new default setting somewhere that's causing it to sample from a larger area, maybe? When I'm clicking on the black area, is the wand sampling everything in the vicinity and trying to select everything in that entire range? Whatever it is, how do I change it? Tolerance has absolutely no effect on what it selects, now. The tool is simply of no value the way it's working now.

Thank you SOOoooooo Much!
The eyedropper tool connected to the wand? How would I know that?
Is it really that hard to add it's own drop down to select the selection size.
Adobe, if you read this, listen. The amount of excise to switch tools, change that setting, then come back to the tool I was just on is not worth the 10min saved during implementation to only have one drop down for this.
You basically invented the adaptable toolbar with butcons, please, please use them.
