Creating image from text
Hi guys! I want to write/find a way to create image that contains some text. For example when you sing in to yahoo.com it shows you an immage with text that you should input to prove that you`re registering from the site .. How to do this?

Brilliant way to create titles from text files
It was just pointed out to me by a fellow named Greg Hester that there is a way to create titles from a Microsoft Word file using Adobe InDesign. You can create as many titles as you need, and even change text positions around from title to title. Then you export as a PNG.
If you need to go back and change a color or a font type or size or whatever, you can do that to all of them at once and then just export again. They will automatically update in Premiere Pro.
I have never even opened InDesign before, and I was able to follow the instructions in this tutorial without a strain.
The tutorial doesn't show that you can import a frame capture from the video to help position the text, but you can.
This is very cool. If you subscribe to the Creative Cloud, then you have access to InDesign.Best would be to have this template/style functionality in the title tool itself though
Agreed.
Remember, all this InDesign thing does is create images that can be used as titles. My Macro created actual titles.
What really needs to happen is to have a plugin that creates titles from simple text files like the ones created from Notepad, so no Microsoft program is required. The file could have the text, the font style, and many other parameters, and then it could have the time to place the title on the sequence.
But in the meantime, this InDesign thing seems to be the best we can do for now. If, however, you want to use a fancy font style and it will all be in English, you can use my macro. -
How to create Image from 8-bit grayscal pixel matrix
Hi,
I am trying to display image from fingerprintscanner.
To communicate with the scanner I use JNI
I've wrote java code which get the image from C++ as a byte[].
To display image I use as sample code from forum tring to display the image.
http://forum.java.sun.com/thread.jspa?forumID=20&threadID=628129
import java.awt.*;
import java.awt.color.*;
import java.awt.image.*;
import java.io.*;
import java.util.*;
import javax.imageio.*;
import javax.swing.*;
public class Example {
public static void main(String[] args) throws IOException {
final int H = 400;
final int W = 600;
byte[] pixels = createPixels(W*H);
BufferedImage image = toImage(pixels, W, H);
display(image);
ImageIO.write(image, "jpeg", new File("static.jpeg"));
public static void _main(String[] args) throws IOException {
BufferedImage m = new BufferedImage(1, 1, BufferedImage.TYPE_BYTE_GRAY);
WritableRaster r = m.getRaster();
System.out.println(r.getClass());
static byte[] createPixels(int size){
byte[] pixels = new byte[size];
Random r = new Random();
r.nextBytes(pixels);
return pixels;
static BufferedImage toImage(byte[] pixels, int w, int h) {
DataBuffer db = new DataBufferByte(pixels, w*h);
WritableRaster raster = Raster.createInterleavedRaster(db,
w, h, w, 1, new int[]{0}, null);
ColorSpace cs = ColorSpace.getInstance(ColorSpace.CS_GRAY);
ColorModel cm = new ComponentColorModel(cs, false, false,
Transparency.OPAQUE, DataBuffer.TYPE_BYTE);
return new BufferedImage(cm, raster, false, null);
static void display(BufferedImage image) {
final JFrame f = new JFrame("");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().add(new JLabel(new ImageIcon(image)));
f.pack();
SwingUtilities.invokeLater(new Runnable(){
public void run() {
f.setLocationRelativeTo(null);
f.setVisible(true);
And I see only white pixels on black background.
Here is description of C++ method:
GetImage
Syntax: unsigned char* GetImage(int handle)
Description: This function grabs the image of a fingerprint from the UFIS scanner.
Parameters: Handle of the scanner
Return values: Pointer to 1D-array, which contains the 8-bit grayscale pixel matrix line by line.
here is sample C++ code which works fine to show image in C++
void Show(unsigned char * bitmap, int W, int H, CClientDC & ClientDC)
int i, j;
short color;
for(i = 0; i < H; i++) {
for(j = 0; j < W; j++) {
color = (unsigned char)bitmap[j+i*W];
ClientDC.SetPixel(j,i,RGB(color,color,color));

Disk Utility fails to create image from double layer DVD
I burned a double-layer DVD using iDVD. It plays fine on the mac and on set-top DVD players. However, when I try to create an image of the DVD using Disk Utility, I get "Can't create image 'name.cdr' (input/output error)". I've tried re-burning the original disk, but it gets the same error when trying to create an image. I've also tried each of the image types, all with the same result.
I was having similar problems, although I don't think my issues was related to a double-layer DVD. What worked for me was selecting File > New > Disk Image from Folder. Select the DVD in the file open/save dialog with the same options you used before (e.g., DVD/CD master, etc).

Disk Utility: Create Image from Volume Without Unused Space
I'm trying to create a disk image from a mounted volume (flash memory in a video camera) but I don't want to write to it later, it's just for archiving. The problem is that the size of the original volume is 16 GB, so every image I create is huge, even if there is less than a 1 GB used.
For example, I only have two short clips on there, about 1.1 GB used. When I create a new .dmg from the volume, the file is 5.28 GB and when I mount it it tells me the size of the volume is 15.3 GB. Clearly I understand why this is happening, it's creating a bit for bit copy of the original volume, but I don't need all that space since I'm never going to write to it.
In disk utility it won't let me resize the image (it's grayed out). What do I do?I actually don't understand why this is happening (when I do this the created disk image only uses the space it needs) but you can get around it as follows. First create a blank read/write disk image to the size you want and then restore the memory card to that image.

How to create PDF from text file with specific layout?
I wanted to create the pdf from text file in specific layout - Landscape orientation and JIS B3 Page size while at Adobe Acrobat Pro.
In past, I could do a right click on a text file (desktop area) and select print to print out the document into .pdf BUT only if I set the Adobe PDF to Landscape and JIS B3 Page size BEFORE. And I could only do 15 text documents at once.
I wanted to see if I could do the create the pdf from text file with specific layout in Adobe Acrobat without having to go to Control Panel to preset the Adobe PDF to specific layout at every time. I would have to set Adobe PDF back to normal layout after I'm done with these pdf print outs. I do lots of pdfs in normal layout. Sometimes I would forget to do that.
So, How do I do that?No such luck. It would output the contents in letter size even in JIS B3 Page layout at MS word.
Is there a script or action where I could set the orientation and page size before creating PDF on these text files? -
Problem creating image from a data vector
Hello i have a problem in this aplication.
I get a image from a web cam. I want to put the original image in a file and the negative image in another file (in this example is not the negative image, is just a white image). The problem is when i use setData method. The image become black. If I use setFormat method the new image is the original image.
Here is the code with problems:
imageBuffer = frameGrabbingControl.grabFrame();
theData = new int[dataLength];
theData = (int[]) imageBuffer.getData();
for (int y = 0; y < videoHeight - imageScanSkip; y+=imageScanSkip) {
for (int x = 1; x < videoWidth - imageScanSkip; x+=imageScanSkip)
theData[y*videoWidth+x]=Integer.parseInt("FFFFFF",16);
Buffer b1=new Buffer(); //This is the new buffer in which i want to put the new pic
b1.setData(theData);
//here i create the 2 files frst from the original buffer and second from the new buffer b1
Image img = (new BufferToImage((VideoFormat)imageBuffer.getFormat()).createImage(imageBuffer));
Image img1 = (new BufferToImage((VideoFormat)b1.getFormat()).createImage(b1));
BufferedImage buffImg = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
BufferedImage buffImg1 = new BufferedImage(320,240, BufferedImage.TYPE_INT_RGB);
Graphics2D g = buffImg.createGraphics();
Graphics2D g1 = buffImg1.createGraphics();
g.drawImage(img, null, null);
g1.drawImage(img1, null, null);
try{
ImageIO.write(buffImg, "jpg", new File("c:\\webcam.jpg"));
ImageIO.write(buffImg1, "jpg", new File("c:\\webcam1.jpg"));
catch (Exception e){}
the webcam1.jpg file is black(it should be white).
If i put "b1.setFormat(imageBuffer.getFormat());" the webcam1.jpg will be same the file as webcam.jpgHello i have a problem in this aplication.

Create image from byte[]array on server side
Hello everyone..
I'm developing an application which will take snapshots from a mobile device, and send it to my pc via bluetooth. I have my own midlet which uses the phone camera to take the snapshot, i want to transfer that snapshot to my pc.
The snapshot is taken is stored in an array byte.
The image can be created on the phone itself with no problem using : image.createImage(byte[])
my problem is that when i send the array byte via bluetooth, and receive it on the server, i cannot create the image using the :image.createImage() code
The connection is good since i have tested by writing the content of the array in a text file.
Piece of midlet code:
try{
stream = (StreamConnection)Connector.open(url);
OutputStream ggt = stream.openOutputStream();
ggt.write(str);
ggt.close();
}catch(Exception e){
err1 = e.getMessage();
}where str is my array byte containing the snapshot
And on my server side:
Thread th = new Thread(){
public void run(){
try{
while(true){
byte[] b = new byte[in.read()];
int x=0;
System.out.println("reading");
r = in.read(b,0,b.length);
if (r!=0){
System.out.println(r);
img = Image.createImage(b, 0, r);
//other codes
i get this error message:
Exception in thread "Thread-0" java.lang.UnsatisfiedLinkError: javax.microedition.lcdui.ImmutableImage.decodeImage([BII)V
at javax.microedition.lcdui.ImmutableImage.decodeImage(Native Method)

at javax.microedition.lcdui.Image.createImage(Image.java:367)

Please anyone can help me here? is this the way to create the image on the server side? thx a lothere is exactly how i did it :
while(true){
byte[] b = new byte[in.read()];
System.out.println("reading");
r = in.read(b, 0, b.length);
if (r!=0){
Toolkit toolkit = Toolkit.getDefaultToolkit();
Image img = toolkit.createImage(b, 0, b.length);
JLabel label = new JLabel(new ImageIcon(img) );
BufferedImage bImage = new BufferedImage(img.getWidth(label),img.getHeight(label),BufferedImage.TYPE_INT_RGB);
bImage.createGraphics().drawImage(img, 0,0,null);
File xd = new File("D:/file.jpg");
ImageIO.write(bImage, "jpg", xd);
System.out.println("image sent");

Create PDF from text fields in website
Hi!
Is it possible to hook up text fields in a website to a PDF document?
I have a website developed in Dreamweaver/asp and I would like the ability to create
a PDF based on values from different text fields (10-12).
Today we first insert the values to a webpage and then insert the same values to a PDF
made in Live Cycle, I'm thinking there have to be a way to automate this process.

Align Columns? using Acrobat Pro 9 to create pdf from text file(s)
Hello,
Every time that I have tried to create a PDF from a text file, the columns dont align. The default Notepad setting I use to view a text file is Courier New which shows the columns aligned. How can I set defaults in Acrobat Pro 9 to have columns align?
ThanksBy definition a plain text file has no font, so it cannot be monospaced. Acrobat converts plain text using Times, this cannot be changed.
As TSN suggests to create a PDF from a text file with a specific choice of font and formatting you must print from another application. -
The CreatePDF app description states "Convert all your Office, Photoshop, ..., Text, and RTF files to PDF using 'Open In' to send the files to the CreatePDF application" (bolding mine). But I see no way in the iPhone Notes app to do an 'Open In'. Really?!? I can't even create a PDF from the standard Notes app?!?
Hello tomscheifler,
notes in the notes-app are NOTES not FILES.
Conclusion: You cannot convert them.
You have take a detour via e.g. "docs to go" and save the note as word doc.
Then adobe does the job you expect....

Create Image from Stream in Applet via Servlet
First of all, I apologize if this isn't posted to the proper forum, as I am dealing with several topics here. I think this is more of an Image and I/O problem than Applet/Servlet problem, so I thought this forum would be most appropriate. It's funny...I've been developing Java for over 4 years and this is my first post to the forums! :D
The problem is I need to retrieve a map image (JPEG, GIF, etc) from an Open GIS Consortium (OGC) Web Map Server (WMS) and display that image in an OpenMap Applet as a layer. Due to the security constraints on Applets (e.g., can't connect to a server other than that from which it originated), I obviously just can't have the Applet create an ImageIcon from a URL. The OpenMap applet will need to connect to many remote WMS compliant servers.
The first solution I devised is for the applet to pass the String URL to a servlet as a parameter, the servlet will then instantiate the URL and also create the ImageIcon. Then, I pass the ImageIcon back to the Applet as a serialized object. That works fine...no problems there.
The second solution that I wanted to try was to come up with a more generic and reusable approach, in which I could pass a URL to a servlet, and simply return a stream, and allow the applet to process that stream as it needs, assuming it would know what it was getting from that URL. This would be more usable than the specific approach of only allowing ImageIcon retrieval. I suppose this is actually more of a proxy. The problem is that the first few "lines" of the image are fine (the first array of buffered bytes, it seems) but the rest is garbled and pixelated, and I don't know why. Moreover, the corruption of the image differs every time I query the server.
Here are the relevant code snippets:
=====================Servlet====================
/* Get the URL String from the request parameters; This is a WMS
* HTTP request such as follows:
* http://www.geographynetwork.com/servlet/com.esri.wms.Esrimap?
* VERSION=1.1.0&REQUEST=GetMap&SRS=EPSG:4326&
* BBOX=-111.11361,3.5885315,-48.345818,71.141304&
* HEIGHT=480&...more params...
* It returns an image (JPEG, JPG, GIF, etc.)
String urlString =
URLDecoder.decode(request.getParameter("wmsServer"),
"UTF-8");
URL url = new URL(urlString);
log("Request parameter: wmsServer = " + urlString);
//Open and instantiate the streams
InputStream urlInputStream = url.openStream();
BufferedInputStream bis = new
BufferedInputStream(urlInputStream);
BufferedOutputStream bos = new
BufferedOutputStream(response.getOutputStream());
//Read the bytes from the in-stream, and immediately write them
//out to the out-stream
int read = 0;
byte[] buffer = new byte[1024];
while((read = bis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, buffer.length);
//Flush and close
bos.flush();
urlInputStream.close();
bis.close();
bos.close();
.=====================Applet=====================
//Connect to the Servlet
URLConnection conn = url.openConnection();
conn.setUseCaches(false);
conn.setRequestProperty("header", "value");
conn.setDoOutput(true);
//Write the encoded WMS HTTP request
BufferedWriter out =
new BufferedWriter( new OutputStreamWriter(
conn.getOutputStream() ) );
out.write("wmsServer=" + URLEncoder.encode(urlString, "UTF-8"));
out.flush();
out.close();
//Setup the streams to process the servlet response
BufferedInputStream bis = new
BufferedInputStream(conn.getInputStream());
ByteArrayOutputStream bos = new ByteArrayOutputStream();
//Read the bytes and immediately write to the out-stream
int read = 0;
byte[] buffer = new byte[1024];
while((read = bis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, buffer.length);
//Flush and close
bis.close();</code>
bos.flush();</code>
byte[] imageBytes = bos.toByteArray();
//Create the Image/ImageIcon
Toolkit tk = Toolkit.getDefaultToolkit();
Image image = tk.createImage(imageBytes);
imageIcon = new ImageIcon(image);
Could this be an offset problem in my buffers? Is there some sort of encoding/decoding I am missing somewhere?
Thanks!
BenWithout having a probing look, I was wondering why you do the following...
while((read = bis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, buffer.length);
while((read = bis.read(buffer, 0, buffer.length)) != -1) {
bos.write(buffer, 0, buffer.length);
}Your int 'read' holds the number of bytes read in but you then specify buffer.length in your write methods?!? why not use read? otherwise you will be writing the end of the buffer to your stream which contains random memory addresses. I think thats right anyway...

Creating Variables From Text File
Hello a little new to powershell and have banging my head on the wall trying to get this working.
I have a text file (where the numbers of lines will change everytime) that will contain AD groups.
Lets say it looks like this
GroupA
GroupB
GroupC
I'm trying to you a loop that will read the file and output each new line to a variable so
var1=GroupA
Var2 =GroupB
Var3=Groupc
My first problem is that non of these can be null since this will be then be used with Add-ADgroupmemeber
So I have it get the number of items with $Items = get-content *File* | Measure-Object -Line
After that I have been trying to use a loop which to me looks like it should work however is not. I'm not getting any errors. However I'm not getting any created variables either.
For ($i=1; $i -lt $Items.lines; $i++) {
$var[$i] = (Get-Content *File*)[$i-1]
write-host $var[$i]}
In my head I should get a listed of each line of the txt file but I'm getting nothing.
In the end I was hoping to doing something along the lines of ADD-Adgroupmember -identity $Var[$i] -members *Machine Name*
If there is a better way to approach this I'm all ears.
Thanks for any help!You don't need a loop to read each line from the file. You don't need a variable for each group read from the file.
For example, if your file looks like:
GroupA
GroupB
GroupC
with spaces/empty lines in it, that you wish to ignore, you can use:
$Groups = Get-Content .\groups2.txt | % { ($_.split(" ",[System.StringSplitOptions]::RemoveEmptyEntries)) }
The $Groups variable will be an array that holds non-empty lines from the file. You can use that directly as in:
foreach ($Group in (Get-Content .\groups2.txt | % { ($_.split(" ",[System.StringSplitOptions]::RemoveEmptyEntries)) })) {
Add-ADGroupMember -identity $Group -members *Machine Name*

Error message when trying create image from RAID
I am trying to backup my RAID (697 GB) by creating an image (Disk Utility) on an external firewire drive. The settings are Read Only - I get an error message "image/device is too large"
Is my RAID too large at 697GB to create an image?
Thanks,
Steven
Mac OS X (10.4.3)You have all 4 drives striped on the external drive?
I'm not sure it will work -- an image may need to have 2x its actual size during creation. I'd have to check to be 100% sure.
I think, though, it would be a lot better if you just did a pure "dupe," of the files from one volume onto another, rather than creating an image. It will be a ton easier.
