Photoshop :: How To Extract Different Pixel Area
Jul 15, 2013
I am using Photoshop CS5.
Right now I am trying to extract edited area and add some effects only on the area. I added some hand paintings on a picture and I need to extract hand painted area from the picture and add some effects on the extracted hand paintings and combine it with the original picture. I know I should hand paint on a different layer and add some effects on the layer and combine it with the picture, but I have to do what I am doing right now.
See pictures below.(those pictures are much simpler than my pictures I am editing right now)
There is a layer that has only 1 color, green.And 2nd picture has pinky letter A on 1st layer, so 2nd layer has green and pink color. I need to extract pinky A letter from 2nd layer and need to add some effects only on the letter A, and combine 1st layer and edited letter A to make 3rd layer.
I tried to use blend mode Difference to extract edited area but it changes the color of the area.And I don't want to use select tool & alpha mask, because my picture is much complicated.
What I want to do is something like Difference Matte effect in After Effects. Is it possible in Photoshop?

I am trying to take a jpg file of an image, and write each RGB pixel color's value into a 3 component integer vector corresponding to the RGB components of the color for that pixel. For each pixel in the jpg, I wish to write the corresponding 3 by 1 integer vector into a matrix after which I plan to do a SVD decomposition of the newly constructed matrix to do an image analysis.
Any plug-in that allows one to efficiently iterate through each pixel in a jpg, and convert the pixel data to a RGB integer vector, and say write to a file?
Specific Details: I am using gimp 2.6 as my image editor, and wish to collect all the RGB 3 by 1 integer vectors (where each 3 by 1 integer vector corresponds to RGB color of exactly one pixel in the jpg image) into a matrix of integer so that I can do a reduced SVD decomposition of that matrix to analyse the pixel data: I wish to compare two similar images by using the SVD decomposition of integer matrices corresponding to the two images saved as jpg files pic1.jpg and pic2.jpg.

For a research project, I am calculating the area of the cytosol of a cell by finding the total cell area and subtracting the total nuclear area. I have been using the lasso tool to select the boundaries and then the histogram to measure the total pixels in that selection area. Proportionately, the nuclear pixel area should always be smaller than the total cell area since the nucleus is inside that cell. Most of my measurements have been accurate, but I started to run into the problem in which occasionally the nuclear pixel area is larger the total cell area. This does not make sense, which means that Pixel # that the histogram records must not actually be counting every pixel. I have tried to do some reading online and it sounds like the histogram is made based on different color intensities. If that were the case, that histogram pixel count is not the total area of the selection but rather only the pixel count that is being used to calculate the histogram.
I have tried changing the Channels from grayscale to RGB, etc. to see if that might use more of the pixels but there is no difference. What is the difference in these measurements and how can I make sure that the histogram counts every pixel?
Also, once I have that issue figured out, to convert my pixel count to a cell area, do I use the equation
A=P/s^2?
A=real cell area
P=pixel count
S=linear pixel/cm.
I have a bar scale from the microscope on the bottom of each image, thus I can accurately find this variable. I would have to square it since I need the area. Does that look correct?

How can I extract text from polyline area. Ideally scaled by some factor (drawing in millimeters convert to area in meters).
I need to write a lot of areas of some room etc. into them and i want to know if there is another possibility than select polygon note the area and make text.
I'm unsing AutoCAD 2005 CZ.

I have a layer with a vector mask.
When I go to the properties panel, enter the feather radius „0.5“ and hit the enter key it rounds it up to 1 (Pixels).
Entering „0.4“ and hitting enter gives 0.
4.3 gives 4
4.6 gives 5
and so on.
So hitting enter rounds the value, although decimal values are accepted and do work. Why is that? What's the purpose of rounding the number?
When I enter „0.5“ and click somewhere it works without changing it to 1. Then it's really just 0.5 px. But hitting enter (the most natural thing after entering some value) rounds it.
Is this a feature or a flaw?

I created walls for a structure by drawing a simple polylines and extruding it by the Z axis, so that i get a vertical plane. I created a number of such planes in the layer. I want to extract total area of this layer which has these polyline extrusions (planes). I know the command of add area, but it is a tedious process and does not work for curved planes. How do I extract the area for the entire layer in one go ?

I have two art objects on two layers. I want to match to the pixel the two objects that otherwise could be exactly the same but one layered object was imported slightly smaller.
The scale tool has good scale handling, I just want to measure the tool spots to the pixel to gain an exact scale size factor and match sizes.

It blows my mind that somthing this simple isnt all that simple. I used the eyedropper tool to slect a color from another photo, then used the brush while fully magnified to change the color of each pixel.
It was coming out a weird greyish color, and I noticed that if I clicked more than once, it got darker, but so did the pixels directly around the one i was editing. So, i copied both pictures, loaded them into paint, and went to town.
It worked, but then when i copied it back into photoshop, it had a black background (there was no background in the original pictures) around the sprite I was editing. I tried to use the magic wand tool to get rid of it, but it took parts of the sprite with it, so...
Is there any way that I can edit the color of a single pixel (or hell, even a group of pixels if they share the same exact color would be nice...preferred, even) accurately? If not, what program could I use that would keep the transparent background?

I managed to remove the background, of an image,(A whit background) and put the image on top of a transparent layer. made a transparent image. When I place this image over a light color background, it looks fine, but when I place it over a dark color background, the edge of the image looks very rough and dirty, I think it's because some of the anti alias from the original image, how can I make it a clean image without going to delete pixel by pixel?

We are developing an application using functionality of Gimp´s channel mixer with java.
Our problem is that we don’t Know how channel mix works exactly for transforming pixel by pixel in Java.
For example,
We have an image an do on it the next mix:
Output Channel = Red
Red=200.0
Green=0.0
Blue=0.0
For simulate that, we transform all pixels with Red Component *2 and 255 (maximum) if is greater.
Our problem is:
Output Channel = Red
Red=200.0
Green=60.0
Blue=0.0
How can I simulate that?

I'm using Photoshop CS5 and as you can see on the picture below, when I set my grid line to every 1 px, grid doesn't match canvas pixel size.
Now I'm not able to draw sharp shapes using pen tool because even if I hold shift key everything gets blurry.

When I drag around vector points of paths they are not constrained to the pixel grid, when the option "Snap Vector Tools and Transform to Pixel Grid" is off. This is the behavior I expect.BUT: When I drag whole paths, they snap to the pixel grid, no matter what. I even have snapping completely disabled.
This is particularly annoying when eg. creating a path for a zipper. I first make a path for the inside of the jacket or whatever, then I make one notch for the zipper and copy it over and over again for all the notches. It's very troubling when these elements snap to the pixel grid, because it's very unprecise then.

I've recently migrated from AutoCAD 2008 (non-industry specific) to AutoCAD 2010 so I don't know if this was an issue in 2009.
Back in 2008, when I choose the 'window' option when specifying a plot area, AutoCAD would show the workspace so that I could manually select a windowed plot area, and at the same time the whole workspace would be greyed out except the previously active window area.
This was handy, because we can have as many two dozen title-blocks (and therefore separate viewports) in paperspace, and knowing what plot area I last plotted or added as a saved page setup.
In 2010, it no longer does that. I now have to rely on the dashed border to know where the active plot area is/was (checked 'display printable area' in options>display tab) which I personally don't really like using.

How to changes the settings for the "Square Area" in mapcheck's closure summary. When I right-click the dwg name in the Settings tab of Toolspace and choose Edit Drawing Settings, then Ambient Settings, I see the Area settings, but in the closure summary, there is also "Square Area". Why are these both there? It WOULD be nice to show sq. ft. as well as acres, but I can't find anywhere to edit it.

I want to know if there is an easier ACAD solution for drawing. In the given triangle of ABC (sides and angels are known) I want to draw line CM so that the area of BCM becomes 2000 cm (are of ABC is 5311.7 cm3).
Is there an easy ACAD way for drawing this line without using trigonometry for calculation?

How can you do the area takeoff of only the selected faces (red area)?
Right now I have to use the 3rd party software to do something like this. I'm curious if there's a way to do inside Revit?

I need to determine whether an area intersects with another area.The left case can be easily determined by Polyline.IntersectWith(Polyline...).But in the right case, the two polygons intersect/overlap each other while polylines do not intersect.
What would be the efficient way to determine the right case polygons are intersecting polygons?

Is there a way to extract or export or convert a PDF to PSD with layers. So I'm thinking the answer may be no but I'll ask anyways. When I open the PDF in Photoshop CS5 I only see one layer. If the PDF was saved with Photoshop capabilities would I see multiple layers or is this something I need to turn on or convert it myself?

I can't extract the Photoshop CS5. Everytime I try I get :"A problem occured while extracting some files. Check available space on your computer and the write privileges on the destination folder" .I've spent long hours on the phone with multiple agents trying to resolve this issue. I have WinZIP, my computer is Windows 7 Pro, etc... Still cannot get the issue resolved.
As well, while on the phone with one of the Adobe Agents, I was informed to type in: "cmd.exe" in the start menu, then once the window opened I was then informed to type: "net user administrator /active:yes". This created a whole new Administrator account for me, when I already had an Administrator account saved under my name. So now I'm stuck with two and I cannot get rid of the Administrator account that the Adobe Agent made me create. I've tried many things in reference from google. Such as: Right Clicking Computer on the startup menu then clicking manage Local Users and Groups. I then clicked Groups and tried to delete the Administrator account, however it would not allow me. Then I tried to type in "cmd.exe" in the Start Menu, once the window opened I proceeded to type: "net user administrator /active:no", and yet again it did not work.

The old, (un)reliable Extract filter is not part of Photoshop CS4, and Adobe isn't planning on bringing it back! Instead, Extract will be replaced by sometyhing altogether more powerful in future releases of the software (working alongside Refine Edge so I hear).
Luckily for anybody who's a fan of the Extract feature, Adobe are planning to make it available, for the time being, completely free of charge on the Adobe website. Also, if you have previous versions of Photoshop, you can copy and paste it from an old version into the filters folder of the new version and things should work out perfectly!
So do we have any extract users here who'll be sad to see it go?

The following disk images couldn't be opened:
Master Collection error 4960
Then it says forver extracting. This happened becuase the download got interruted, my computer shut down too early. I did what other poeple said to do in the forums:
erased cookies
uninstalled the adobe assistant
created a different account in adobe
tried to download it with Firefox and then Crome
Don't know what else to do.

I'm looking for a way to replace a certain colour with transparency.
Exactly like the replace color/selective color tool, exept instead of changing the color to a diffarent colour, it is replaced with transparency.
I don't mean anything like the magic wand tool or removing one
