Saving each layer into a file?

Hello everyone,
I need to take each layer's data and save it into a file. How would I retrieve individual layer's image data?
Thanks

The ReadLayerDesc and associated callbacks ARE how you get the color data and opacity for each layer.
And layers don't have alpha channels - those belong to the document.
(sounds like you are confusing opacity with alpha channels)

I received pictures in a dozen emails and saved each picture into one file in .pages. I did not import the photos before doing this and now iPhoto won't recognize the pictures because they are in a .pages file. How do I get the pics to iPhoto?

I received a dozen pictures in a few emails and I saved them all into one file in pages. I just copied and pasted. I do not have the originals any longer. Iphoto will not permit me to import the pictures as it does not recognize a .pages file, nor can I simply click and drag from the pages document to iphoto nor from pages to the desktop to iphoto. How can I save each picture I guess back into a jpeg and then import them into iphoto or have i lost them to a pages document forever? This is urgent as I need the pictures made into a book on iphoto for work by Friday!!! Please advise! Thank you.

Greetings,
Locate the Pages document wherever it's located on your computer and click once on it to highlight it.
Go to File > Duplicate to make a backup copy of the file.
Click once again on the file to highlight it.
Go to File > Get Info
In the "Name & Extension" category remove the ".pages" extension and put in ".zip".
Close the info window and double-click the now renamed pages file (zip file now).It will decompress into a folder which contains all the base components including all the images you added. These can be dragged onto the iPhoto icon to import them.
Hope that helps.

How can I export the number of pixels of each layer into an excel file?

I would like to export the number of pixels that each layer of an image contains into excel. How can I do this?
Secondly, as I need to do this with several images, is there any way to name the layers so that all layers with let's say for example the name "yellow" appear in the same column in excel?
Some background information on why I need to do this... I would like to know how many percent of an image are yellow and have therefore created layers of one image for each color it contains.
Thanks for your help!!!

Maybe my question was a bit unclear. I do not want to find out the number of pixels of a color in a layer but the number of pixels of the complete layer.
What color these layers are is a different question. I am using images with a very limited range of colors (sort of like the image above but with about 10 colors). I have seperated these colors into layers and now need to count the pixels of each layer and export them.
You can record number of pixels/layer into the Measurement Log, then export data to Excel. But I'm not sure how to automate that without scripting.
Does anyone know how to do this?
For normal artLayers it is somewhat easy to get the number of pixels in the layer. But that is just how many pixels are in the layer.
But that is exactly what I need to know, how many pixels are in the layer. I know how to find this out by looking at the histogram of the selection. But I want to export this information of all layers at once into an excel or text file. Any ideas on how to automate this with or without scripting?

Save each layer to a file but take care of a top set HUE Adjustment Layer

Hello,
I am using a PS script to save each layer as a png image to disk. It is a modified Adobe PS Script - based on the "Export Layer to File"- script. The script is working fine - however when I use an HUE Adjustment Layer the settings are not rendered into the images. I have a PS CS4 document with 110 layers and 1 HUE adjustment layer at the top of all those layers to modify the color of all layers at once. I need to save all the 110 layers to disk INCLUDING the changes in the adjustment layer. The layers are stored in 55 Layersets. Each Layerset has 2 Layers. The adjustment layer is on top of all layer sets.
At the moment, when I start the script the images will be saved without the adjustment layer settings. How can I do it - in general - to apply either the adjustment layer to all my layers upfront in PS (render into image) - or apply the adjustment layer to each layer when the layer image is saved to disk using the script. Again, I have only 1 Adjustment Layer at the top of all my layers/layersets.
Thanks for any hint!

Saving multiples objects into a file

I want to create a single file that has multiples things inside, like pictures (png) and texts. Does someone knows how it will be the structure of the binary file?
I'm programming a draw software like photoshop, where my layers are BufferedImages. Theses bufferedImages must be saved into a file to re-open later and edit.
Please I want just ideas....
thanks

If the objects that you store in your file are fairly independent of each other, one thing that comes
to mind is to make your file a zip file of component files. That way you can use standard tools to examine
it and edit it if you wish.
Another thing to note is that if your file is largely a series of images, some image file formats,
like tiff , jpeg and gif allow you to store sequences of images in one file.
Here's a demo that creates a tiff file holding four images, then reads the file and displays the images.
Stardard software like Kodak's "Imaging Preview" will allow you to flip through the images in the file.
By the way, if you don't have readers/writers for format tiff, you can get them here.

Saving multiple records into text file

Can I save multiple records into a text file at one go?
My application has a list of data displayed there and when the user clicks on the save button it will save all the records on the screen.
It works but it only saves the last record.
Here are my codes
// this is to display the list of data
private JLabel[] subjects=new JLabel[20];
private JLabel[] subTotal=new JLabel[20];
private JLabel[] codes=new JLabel[20];
private JLabel[] getTotal=new JLabel[20];
String moduleCodes;
String getPrice;
double price;
int noOfNotes;
public testapp(Subjects[] subList)
int j=0;
          double CalTotal=0;
          for (int i=0; i<subList.length; i++)
               subjects[i] = new JLabel();
               subTotal[i] = new JLabel();
               codes=new JLabel();
               getTotal[i]=new JLabel();
               if (subList[i].isSelected)
                    System.out.println(i+"is selected");
                    subjects[i].setText(subList[i].title);
                    subjects[i].setBounds(30, 140 + (j*30), 400, 40);
                    subTotal[i].setText("$"+subList[i].price);
                    subTotal[i].setBounds(430,140+(j*30),100,40);
                    codes[i].setText(subList[i].code);
                    getTotal[i].setText(subList[i].price+"");
                    CalTotal+=subList[i].price;
                    contain.add(subjects[i]);
                    contain.add(subTotal[i]);
                    j++;
                    moduleCodes=codes[i].getText();
                    getPrice=getTotal[i].getText();
                    noOfNotes=1;
// this is where the records are saved
     public void readRecords(String moduleCodes,String getPrice,int notes)throws IOException
          price=Double.parseDouble(getPrice);
          String outputFile = "testing.txt";
          FileOutputStream out = new FileOutputStream(outputFile, true);
     PrintStream fileOutput = new PrintStream(out);
          SalesData[] sales=new SalesData[7];
          for(int i=0;i<sales.length ;i++)
               sales[i]=new SalesData(moduleCodes,price,notes);
               fileOutput.println(sales[i].getRecord());
          out.close();

I suggest writing a method that takes a SalesData[]
parameter and a filename. Example:
public void writeRecords(SalesData[] data,
String filename) throws IOException
BufferedWriter out = new BufferedWriter(new
FileWriter(filename, true));
for (int i = 0; i < data.length; i++)
out.write(data.getRecord());
out.newLine();
out.close();
And it's good to get in the habit of doing things like closing resources in finally blocks.

Saving business objects into xml file

I have the following XML file parsed into a DOM tree, with 2 different types of nodes "TestCase" and
"RealCase". Then I mapped each type to a different type of business object, TestCaseObj and RealCaseObj.
Now, there may be addition of new objects, or modifications to the data stored in the business objects
by my application. Eventually when I save the business objects back into the XML file, how should I go
about doing that?
<ROOT>
<TestCase TestID="T1">
     <Element1>Data1</Element1>
     <Element2>Data2</Element2>
</TestCase>
<TestCase TestID="T2">
     <Element1>Data1</Element1>
     <Element2>Data2</Element2>
</TestCase>
<RealCase ID="R1">
     <Element1>Data1</Element1>
     <Element2>Data2</Element2>
     <Element3>Data3</Element3>
</RealCase>
<RealCase ID="R2">
     <Element1>Data1</Element1>
     <Element2>Data2</Element2>
     <Element3>Data3</Element3>
</RealCase>
</ROOT>

The DocumentBuilder class does not allow you to parse a portion of the xmlfile. Therefore, it will not be possible to read "TestCase" into the DOM without bringing in "RealCase" nodes as well. As such, these codes will parse the entire xml file into DOM:
DocumentBuilder builder = builderFactory.newDocumentBuilder();
Document document = builder.parse( xmlFile );
However, your problem can be solved by reading only "TestCase" nodes in DOM, as follows:
NodeList elementNodeList =
elementNode.getElementsByTagName("TestCase");
Your codes will then change the data in the elementNodeList, without affecting "RealCase" although it is loaded into DOM. You can be sure that elementNodeList contains only "TestCase" nodes.
Once you have made your changes, save the DOM back to the XML file, using the serializer method as discussed earlier.
Good luck.

Saving an object into a file

Problem with data saving into text file

Hi,
The problem I am facing wihile saving the data into text file is that everytime when I am slecting the path from front panel, the data which is being saved is appended with the previous data, i.e. not only in the new text file, the new set of data is saved but also, if there is any previuos run for the program, the corresponding data is also present in that text file.
However, when I change the same 'control'(file path) to 'constant' in the block diagram, and add the file path, there is no such problem. Basically, changing the "File path" from constant in the block diagram to control (so that it is displayed in the front panel) is causing the problem.
Please help!
Thanks
Solved!

Your shift register on the For loop is not initialized. It will retain the value of the string from the last time it executed. Initialize that and it should solve your problem.

Is the number of histogram pixels the same for each channel within each layer?

Dear Photoshop Scripting Forum:
I have written a script to isolate the number histogram pixels for each channel within each layer of a file.
However, I have found some unexpected results: That, the number of pixels is the same for each channel within each layer.
For example,
Layer 1 has 18,979 pixels by itself, and so does each channel within it (Red, Green, and Blue)
Layer 1, Channel Red, has 18,979 pixels
Layer 1, Channel Green, has 18,979 pixels
Layer 1, Channel Blue, has 18,979 pixels.
This does not seem right to me.
Does someone else have the same experience, or knowledge of something else?
I am wondering if there is a bug in my script.
If need be, I will post the script, but it's kind of long for a forum.
Thank you.

The following is for RGB 8bit images.
The red historgram is an array of red values of the pixels that range from 0 to 255. Each element in the array has the number of pixels that have that red value. So for example if you had a layer that is pure red 255,0,0 all the pixels would be in the 255 element and there would be no pixels in the other elements. The red historgam still has the same number of pixels as the layer. They are just all in one histogram element( they all have the same value ).
But even if you know that all the pixels in a layer are all in the last element(255) of the red histogram you still don't know the color of the pixels. A white pixel has a red value of 255. So does a yellow, magenta, etc pixel. If you only know the red value of a pixel the pixel could be one of over 65000 colors. Most of which would not be considerd 'red'
It is the three channels together that detemine a pixel's color. Unless the layer is one color you can not tell the color of the pixels from looking at the histogram.
Unless you use the color range selection then get the histogram of the selection. Even then you need to decide what color value make up 'red'

Saving ALV Grid to Local File issue - Missing half of the report

Hi Experts, Good Day.
I have developed an ALV Grid report using class CL_SALV_TABLE which displays 200 Columns and 100+ rows/records. It is displaying well, but when I am saving the output into local file (any type) there only 98 columns are downloading and remaining all the columns are missing.
I would like to know whether there is any restriction for number of columns or what might the problem for it. How can I download all the columns into local file.
Thanks in Adv.
Vijay

Hi,
Thanks for your response. Even though there are multiple ways to send data to local file I believe all three are same. And even I am facing same issue all the ways. Only 98 Columns data is getting downloaded into Files (it might be .txt, .xls, etc.).
After downloading first 98 Columns, I am hiding the downloaded columns and again I am downloading remaining columns. Then I am merging in the Excel file. This is very complicated for the End-User. So, please help me out.
I have used only following methods for displaying ALV.
For initial object/instance:
CL_SALV_TABLE=>FACTORY,
For ALV functions:
CL_SAVL_TABLE->GET_FUNCTIONS,
CL_SALV_FUNCTIONS_LIST->SET_ALL,
For Column heading and Optimized width:
CL_SALV_TABLE->GET_COLUMNS,
CL_SALV_COLUMNS_TABLE->SET_OPTIMIZE,
CL_SALV_COLUMNS_TABLE->GET_COLUMN,
CL_SALV_COLUMN->SET_SHORT_TEXT,
To display grid:
CL_SALV_TABLE->DISPALY.
- Thanks

Files corruption? - Large squares of each layer are erased when opening files.

Hello,
I have a problem with my PSD files: I create a documents with multiple layers. When saving the files look OK, then when I close and re-open them, some part of each layer simply aren't here anymore. Squares of approximately 350px by 350px are erased from each layer! I have no idea where that can come from. I'm lost there.
I work with Adobe CS5 on an iMac 27 2.66Ghz i5 with 8Gb, OSX 10.6.4
Thanks for any help!

Could be disk corruption, bad RAM, or just a problem with OpenGL drawing on your system.

Combining multiple layers into one "final image" then working on each layer's opacity to affect what the final image looks like

Ideally the "final" image would be displayed. I'd go over to the layers panel and work on each layer, dialing up and down the opacity and see the effects on the "final" image. This is in regards to interior real estate. Normally I combine my images in Photomatix (different exposures) and have that method down. But what I'd like to be able to do is to, say, strobe different areas of the scene while shooting maybe six images (same exposure), load those six into CS5 (File>Scripts>Load Files Into Stack) then proceed.
I've looked at a ton of videos on Youtube and searched CS5 Help and just can't find the answer to what exactly what I'm trying to do. I can choose Edit>Auto-Blend Layers and that does indeed give me a final image (like in Enfuse or Photomatix) but I haven't found a way to then adjust each individual layer to affect that final image. And I know there's a way, maybe coming at this from a completely different direction. Thanks.

Ok I will take the last question first, since that is probably the easiest.end
A merged file or a flattened file is the same thing as a composite.
A merged file still has its transparency and data that is outside the canvas area.
A flattened file is a merged file that is converted to a background layer that does not support transparency or data outside the canvas.
A composite can be a merged copy of the existing layers if you use the multiple key strokes I mentioned above. Whereas a merged file is a composite of the original layers. So I personally use the term composite to mean a copy as merged and flatten already explain that process, no need to give them an additional term to mean the same thing.
Generally blend modes work by selecting individual layers before changing the blend mode. However you can group the layers or convert them to a smart object and apply a blend to that group or object.
Normally you set the blend mode as you work on each layer. But you could set all of them to overlay or reduce the opacity to 30 or 50 percent to see through all the layers, then adjust them later on.
I am not sure how it works on the mac, but on windows you can select the blend text box then use the up and down arrow keys to change the blend mode to see how it looks.
I recommend that you go through the free videos on layers, masks, opacity, and layer styles. This will help you dramatically. Also a few books on the subject will help has well.

MPEG Layer 3 audio files have changed into MP3^^ files,What is ^^

MPEG Layer 3 audio files have changed into MP3^^ files,What is ^^ and why wont the music files play anymore??

I reinstalled OSX on my macbook which previously played all avi files with no difficulties. Now I am having difficulties playing Avi files with quicktime PRO that use the Mpeg layer 3 codec. I have done the following with no success: downloaded flip 4 mac, divx, xvid, 3ivx, Xvid codecs, changed MIME settings, and deleted and reinstalled.
Depending on the specific version and sometimes the ordering in which they were installed, you may have created a conflict among the components here. While most current VidX components should be able to play MPEG Layer-3 audio, v5.1.1 is the only free VidX codec that is bi-directional. If that is not a problem, then I would recommend you remove (or "hide") all components in the main "Library > QuickTime" folder. Next I would determine if one (or more) of the AVI associated components can actually play the specific files mentioned on their own. You do this by installing a compenent to be tested, opening the player with one of the problem movies, and checking for correct audio and video playback. Log your results, close the player, remove the tested component, and move on to the next component to be tested. Once you deterime which component(s) may function correctly, I would then move on to determine which specific components are in conflict by repeating the tests but leaving the components installed after each test. In this case start with a component that is known to work and is the one you most desire to use (if more than one works). If the player stops working, then you have located a potential conflict. Set the offending component aside and continue testing until all components have been tested and are either installed or set aside. The last step is to simply evaluate component alternatives and configure you system for those files most often played. In my case the VidX v6 Pro components did not seem to get along with the 3ivX D4 v4.5 and/or Casio AVI and/or XVIDDelegate component combination.

I have 2 ipods,one for music and the other for old time radio shows.Each had their own file.My computer crashed and I had to buy a new one.Now both ipod files are merged into one.How do I seperate them.

Hi Craig
Unfortunately, in your case, there isn't really a way to separate them as far as I can think.
You could try restoring from a backup, and choosing an older backup perhaps
