Import bitmap into an array

I want to import a 24-bit bitmap image into an array so I can loop through the array and perform calculations based on the color of the pixels etc.
Can any one advise me of an easy way to do this in Java?
Thanks

I want to import a 24-bit bitmap image into an array so I can loop through the array and perform calculations based on the color of the pixels etc. java.awt.image.BufferedImage:
public int[] getRGB(int arg0, int arg1, int arg2, int arg3, int[] arg4, int arg5, int arg6)
it works for jpeg and png, dont know about bmp.........

Problems importing Bitmaps into Editing Workspace

Hello, I Hope someone can help me.
I am using Photoshop Elements 6 and I have captured literally hundreds of BMP Files from a home made video.
I am trying to produce a number of animated sequences by removing the background to leave the subject matter which I then intend to overlay onto a new background in a series of frames.
The Problem I am having is that when I try to view the image in the Editing Workspace, the image resolution is distorted and stretched out horizontally!
The original file is 640 X 480 Pixels and around 900Kb. I am using Windows XP SP2 with 512MB Ram and 3.06Ghz Pentium 4.
I can view the thumbnails in the organiser OK but for some reason when I go to edit it appears as a thin line across the editing workspace at 1%. When I have tried to edit the Image Size it is showing the Document Size as being 0.18cm Wide by 0.14cm High with a resolution of 8902.125 !!!!pixels/inch when it should be about 72?
I have imported one of the BMP files into Fireworks and exported it as a PNG then edited it in PE with no problem.
I can also import JPEG files directly into PE and edit without any problems.
I have just spent over a hour on the phone to Adobe Technical Support who could not help me.
I have un-installed and re-installed and it has not solved the problem.
Has anybody got any ideas please so I do not have to re-save every file as a PNG or do you know of an alternative method of producing the animation?

Are you saying that the problem is with BMP files only?
Did you tried to edit the same file in other editors like Photoshop or any other??
Try to crop the same file in Organizer, if it works reset editor preferences and try again...

Losing data when importing excel into an array

Hi,
I have been writing some code that imports data from an excel .xlsx worksheet file containing 890 columns and 150 rows.
When I set the VI to import 702 columns everything works fine. When I try to import 703 columns I get no data in my array. The VI continues to run without any errors just gives me no results as there is no data in the initial array.
Can anyone tell me if there is a setting somewhere Im missing or explain why this is happening as I have read that there should be no limit to the amount of columns you have as long as you have less than 2^32 elements which I am well below. I am using a Labview 2009 and a PC with windows7 64bit and 4G RAM so there should be no problem with PC resources.
Thanks,
Ray.

Hi Ray,
702 is the limit when you use just 2 chars for the column name: "A" to "ZZ" allows for 702 columns.
Probably a subVI somewhere deep in your Excel loading routine is limited for that naming scheme (or is only aware of older Excel versions)...

Reading from file into an array

Hello, new to Java and we need to modify a mortgage calculator to read interest rate from a file into an array and not have them hard coded in the program. I have read many post on how to perform this but am lost on where to put the new code and format. Here is my code and I hope I posted this right.

OK, making a little progress but am still very confused.
What I have is a file (int&term.dat) with three lines;
5.75, 30
5.5, 15
5.35 ,7
I have three JButtom that I what to read a seperate line and place the term in a term TextField and a rate in a Rate TextField
I have added the following code and all it does now is output a black space to the screen; I am working with one Button and Just the rate for now to try and get it to work. I have been looking at the forums, reading the internet and several books to try and figure this out. I think I may be getting closer.
public static void read()
    String line;
    StringTokenizer tokenizer;
    String rate;
    String term;
    try
        FileReader fr = new FileReader ("int&term.dat");
        BufferedReader inFile = new BufferedReader (fr);
        line = inFile.readLine();
        while (line != null)
        tokenizer = new StringTokenizer(line);
        rate = tokenizer.nextToken();
        line = inFile.readLine();
         inFile.close();
         System.out.println(new String());
         catch (FileNotFoundException exception)
               System.out.println ("The file was not found.");
          catch (IOException exception)
                System.out.println (exception);
}

(Urgent help needed) how to read txt file and store the data into 2D-array?

Hi, I have a GUI which allow to choose file from the file chooser, and when "Read file" button is pressed, I want to show the array data into the textarea.
The sample data is like this followed:
-0.0007     -0.0061     0.0006
-0.0002     0.0203     0.0066
0     0.2317     0.008
0.0017     0.5957     0.0008
0.0024     1.071     0.0029
0.0439     1.4873     -0.0003
I want my program to scan through and store these data into 2D array.
However for some reason, my source code issues errors, and I don't know what's wrong with it, seems to have a problem in StringTokenizer though. Can anybody help me?
Thanks in advance.

1) Next time use the CODE tags. this is way too much unreadable crap.
2) The problem is your String[][] data.... the only place I see you do anything approching initializing it is
data = new String[numLines][];I think you want to do this..
data = new String[numLines][3];anyway that's why it's blowing up on the line
data[row][col]=st.nextToken();

How to insert values into an array of class

Hello everyone,
I need help in inserting values into an array of class, which i have read from a file.
Length of the array is 5. I should insert values one by one into that array.
If the array is full (if count = 5), then I should split the array into 2 arrays
and adjust the values to left and right with median.
I'm getting an ArrayBoundException .. can anybody help me out ?
Thanks in advance

[JS] [CS5] Copy and paste into existing array

Hi Guys,
right now I'm trying to improve the performance of a Script I wrote by copying and pasting a PDF instead of loading it 10 times.
And here's the problem:
When pasting the copied PDF it doesn't paste it into the array the original PDF is in but this is exactly what I need for the further script.
Can I somehow paste the PDF into the Array and a specific position [i]?
I'm adding the important parts of the script.
Greetings Michael

Doesn't anyone know how to do this?
If not, is it possible to:
               1. select multiple grapics in a defined area at once?
               or
               2. paste a graphic and add this graphic to a selection without deselecting the items I've selected before?
thanks in advance

Previewing imported bitmaps for Illustrator CS4 using Windows XP

Hi all
Can anyone tell me if it is possible to preview a bitmap while importing it into Illustrator CS4 (File>Place). I am using Windows XP SP3 and I know you can see a preview on bitmaps with the Mac version.
Any help much appreciated.
Thanks
George

Some general comments (when I used CS3 and WinXp I did not have any problems, now I am on Win7 64bit Pro and CS5)
Check your WinXp configuration and eliminate (not remove, just stop from running at startup) anything you don't really need
Background programs can cause problems for video editing
The usual advice is to disable anti-virus (and, of course, don't connect to the Internet) to reduce the drain on resources
Also do not have other programs YOU start running, so PPro has 100% of the computer's attention & resources
Be sure you have a good device driver for your nVidia card
This is usually the latest one (direct from nVidia, not Windows update) but you MAY need to experiment with driver versions in case a later version does not work well
>HDV project where the bulk of the files are HDV from a Canon HV20
CS5 is much better at allowing different kinds of files in a project, I'm not so sure about earlier versions
If your final output is going to be DVD what MAY help is to do only the HDV part, save out to DV AVI Widescreen, then do the other codecs in a separate project, and finally join the DV AVI files in a final project
CS4 is 32bit so will not take FULL advantage of Win7 and a 64bit computer... but if you have enough memory (I would say 12 or 16 Gig, depending on motherboard) that will allow CS4 to use as much ram as possible
Just how do you have your drives configured?
My 3 hard drives are configured as... (WD = Western Digital)
1 - 320G WD Win7 64bit Pro and all program installs
2 - 320G WD Win7 swap file and video project files
3 - 1T WD all video files... input & output files

Storing a record set into an array

Hello Again,
Yet another road block in my destination to completing my program. I wanted to create a MultiColumn Combobox and needed to store my Database values into an array so I get get them into the Combobox. I'm having trouble getting this code to work properly. It seems that the the combobox wont accept the variable items maybe because it is outside the scope? I tried to move the code around to get it to work but it don't.
here is the code.

He is telling you that there are two problems with your code.
The first is that you are declaring the items array inside the while loop, which means its scope is too limited - it can't be accessed by the JComboBox which is declared later.
The second is that you are recreating the items array for every record in your ResultSet. This implies that for every new record, the item(s) already stored will be removed from memory and replaced by the values of the latest record, leading to a single option for your combo box.
Try instead creating an ArrayList object that you initialise right before the loop, and add items to it's collection as you move along. Then pass that ArrayList to the JComboBox in this way:
          try {
               Connection conn = DriverManager.getConnection(db.connUrl);
               Statement sql = conn.createStatement();
               ResultSet rs = sql
                         .executeQuery("SELECT * FROM Referrals ORDER BY ReferItemText");
               ArrayList<Item> items = new ArrayList<Item>();
               while (rs.next()) {
                    items.add(new Item(rs.getString(2), rs.getString(2)));
               JComboBox jcb = new JComboBox(items.toArray());
               // Close connections.
               rs.close();
               sql.close();
               conn.close();
          } catch (SQLException e) {
               e.getStackTrace();
          }

How Can I Clean up Imported Bitmap Images

Hi, I am using Flash 5. I have imported a sequence of .png images and they are looking pretty rough and bitmapped so I wanted to clean them up.
1. Do I have to select each frame after import and adjust the bitmap settings for each image or can I doo this somewhere so it affects al images?
2. I can’t find the settings for cleaning up the bitmap images. I thought they would be in the “Properties” panel?
3. Is there a way to fix the rasterization or clean up an imported .swf or is it better to clean up the sequence before saving as an .swf?

Ned Murphy wrote:
Ideally you should have images cleaned up/ properly sized / optimized before you import them into Flash. Once they are in Flash, one thing you can do that can help how the image displays, especially if you manipulate its size while in Flash, is to set the image to allow smoothing. This can be set using code or can be manually applied to the image in the library by right clicking it, selecting Properties, and checking the option to Allow Smoothing.
Thanks Ned,
Wow, exactly what I was looking for. Thanks. A huge improvement in the look of the gradients.

Adding pictures into an Array?

The following is a BlackJack Program my group and I made. So far, it seems to work and would likely net us a 100% when we hand it in. However, we wish to go that extra mile and add pictures, cards in particular, something that should obviously be in any card game! I've been fiddling around with ImageIcon and Image but I don't have a clue how to implement these or how to get them working correctly. Also, it would be best if the pictures could be loaded into an array, which would allow the program to function basically the same way with little editing.

Instead of having a JLabel with "Ace", "Eight", etc appear, how would one make pictures appear? How does one do this with an array?
Edited by: Funkdmonkey on Jan 1, 2008 7:45 PM

I guess an array or perhaps better a hashmap where the image is the value and the card (a great place for an enum!) is the key would work nicely. Oh, and you can find a great public domain set of card images here:
http://www.eludication.org/playingcards.html
Finally, your code appears to be suffering from the God-class anti-pattern. You would do well to refactor that beast.

Convert variable into an array

I have variable, abc; whose value is in the format val1,val2,val3,..
I want to convert it into an array, like that arr[0]=val1; arr[1]=val2; so on. How can I do this?
Usman

examine this class that I did
import java.lang.*;
public class ReadString {
public static void main(String[] args){
String abc = "1,2,3,4,5,6";
StringBuffer abc2 = new StringBuffer(abc);
int arrayLength = abc2.length(); //get length
int[] abcFinal = new int[6];
for (int i=0; i<arrayLength; i++) { //test characters
     int anIndex;
     if (!(abc2.substring(i,i+1)).equals(",")) { //if it is a number
     //(i/2) is ta little formula to be able to assign the
     //right index in the intArray to the number
     anIndex = (i/2);
     //set value to array
     abcFinal[anIndex] = Integer.parseInt(abc2.substring(i,i+1));
for (int j=0;j<abcFinal.length;j++ ) {
     System.out.println("i = " + j + " value = " + abcFinal[j]);
}//end main
}//end class

How to import bitmap files?

I have old slides that I scan with a photosmart S20 scanner. The best quality option scan is to save it as bitmap. How do I import it to the Lightroom catalog? Thank you.

I had the HP photosmart S10 scanner (the SCSI interface predecessor to the S20) and it produced GREAT slide scans although only 2400dpi which is generally enough for most uses. If you mean bitmap as in BMP files, you will have to convert these to TIFF or JPG (i would use TIFF as it will be a lossless conversion) to import these into lightroom as BMP is not a supported file type. I believe IRFANVIEW (free shareware) will do this conversion in batch.

How do I convert an image file into an array?

I am using LabVIEW v.6.0.2
I have no NI IMAQ device or IMAQ card, also no Vision
The image file I have can be saved as a file containing numbers relating to the picels. I want to put these numbers into an array and plot a cross section intensity chart ( I am investigating young's double slits experiment and want to see the interference fringes in graphical form).

I'm not sure what you're asking.
In the GRAPHICS palette, there are READ JPEG file, READ BMP file, and READ PNG file VIs. Choose one and together with DRAW FLATTENED PIXMAP and a PICTURE indicator, you can display a picture with two functions and two wires.
If you have spreadsheet-type data and import it with READ FROM SPREADSHEET FILE (in the File I/O palette), you can plot that directly to an intensity indicator.

Getting file into an array of byte..

Hi guys,
i first thank you for all the help you've given in my precedent posts.
Now i've to ask you a question.
I need to convert some lines of a txt file(obtained from an excel table) into an array of byte in the best possible manner.
My file can have a various number of rows and columns.
With this code
BufferedReader br = new BufferedReader(new InputStreamReader(myFile.getInputStream()));
String line = null;
        while ((line = br.readLine()) != null) {
                line = line.replace (',', '.');
                StringTokenizer st = new StringTokenizer(line);
                numberOfNumericColumns = (st.countTokens()-1);
                col=(numberOfNumericColumns+1);I read the file, i change , with . and line to line i calculate the number of value(that have to be the same,i do the control for showing exception if necessary).
Now i know from my file what are the number of values in a row(columns of my old excel table).
I have to convert this file into an array of byte.
How can i do it?
Suppose we have only 3 lines, the first line is ever only string,the others lines have a string and other double values.....
nome giuseppe carmine paolo
valerio 23.3 34.3 43.3
paolo 21.2 34.5 12.2
each value is separated from another one by one or more whitespaces..
The most important thing is that in a second moment i have to read this array of byte and showing its original content,so i have to put in the array some different value and different line symbol delimiter.
Can you help me giving me some idea or code?(please be clear,i'm inexpert of java...)
Thanks very much,i need your help

thanks for your reply...
my file has about 50000 rows..........and i have to develop an application that allows the upload of about 6000/7000 files....
so i have to optimize everythings......i want to use whitespace to separate different value and ;different line
so in my array of bytes i want
nome(converted in byte) whitespace(in byte) giuseppe (in byte) whitespace(in byte)carmine(in byte) whitespace(in byte) paolo (in byte) ;(in byte);
valerio(in byte) whitespace(in byte) 23.3 (in byte) whitespace(in byte) 34.3 (in byte) whitespace(in byte)43.3 (in byte) ;(in byte) etc.....So i should have an array of byte lower than the array of byte obtained converting each line as a string into bytes.......
do you understand what's my problem?
How can i create an array of byte without fixing its initial dimension that is able to grows up for each line read?
Excuse for my poor english..
In the past i've used a vector to temporary store the data while reading the file and at the end i copied the vector in the array of byte but when i do upload in my application i had java heap size error.
So someone has suggested me to improve my storing method and i've decided to eliminate vector....
can you help me......????
please....i need your help..
