Couln't save a buffered image as BMP with java 1.4

Dear friends,
I tried to save a buffered image as BMP with java 1.4. When I run the program ,it executes sucessfully, but no image wasn't created. When I tried the same code with java 1.5 got the right result.
This is the code I have written.
public static void saveBMPFile(BufferedImage bufferredImage, String fileName) throws Exception{
          // TODO Auto-generated method stub
          try {
               Iterator iter =
                    ImageIO.getImageWritersByMIMEType("image/bmp");
          // Get first writer
               if (iter.hasNext()) {
                    ImageWriter writer = (ImageWriter) iter.next();
                    ImageWriteParam iwp = writer.getDefaultWriteParam();
                    iwp.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
                    iwp.setCompressionType("BI_RGB");
                    FileImageOutputStream fios = new FileImageOutputStream(new File(fileName));
                    writer.setOutput(fios);
                    IIOImage image = new IIOImage(bufferredImage, null, null);
                    writer.write(null, image, iwp);
                    bufferredImage.flush();
                    fios.flush();
                    fios.close();
     } catch (Exception e) {
     throw e;
please help me to find its solution.
thanks & regards

Please use code tags http://forum.java.sun.com/help.jspa?sec=formatting
I can see no else for "if (iter.hasNext()) {", so if no encode is found, no error message would be displayed.

Good day.
I have a byte[] and then I have used

This on my web server that has public_html as root web directory.
The server is in multi domain.
In this mode I have an error.
Then I have tryied to use

Drag and Drop Image to PDF with Java Script

Hi,
I have to create some PDF reports and contained within these reports there are numerous images, some as many as 30-40. This is really time consuming. Can anyone please advise if there is some java script available so I may Drag & Drop an image onto a button or directly onto the PDF report.
I have attached an example video of the current process and as you will see the process is very long to say the least. Any assistance would be appreciated.
Kind Regards

Hi Gilad,
Apologies for that I edited the wrong video in my Youtube account.
You mentioned that its not possible with JS.
Are you aware of any other options?
Kind regards

Help! Fix my javascript to save a bmp with suffix in the same folder as the previous save.

Here's my current javascript:
#target photoshop
// sets document preferences to inches
app.preferences.rulerUnits = Units.INCHES
// these are our values for the END RESULT width and height (in inches) of our image
var fWidth = 11.73;
var fHeight = 5.97;
var CurrentDLPFile=app.activeDocument
var CurrentDLPFileName= CurrentDLPFile.name
var CurrentDLPFilePath="~/Desktop/fetch"
var f = File.saveDialog('Save Where?','');
// in case we double clicked the file
app.bringToFront();
// resizes the canvas to 11.73 x 5.97 inches
CurrentDLPFile.resizeCanvas(UnitValue(fWidth,"in"),UnitValue(fHeight,"in"));
// flattens all layers
CurrentDLPFile.flatten();
// saves as photoshop file
if (f!=null) CurrentDLPFile.saveAs(f,undefined);
// splits channels
CurrentDLPFile.splitChannels();
// converts active K seperation to bitmap form
var bitsaveoptions = new BitmapConversionOptions()
bitsaveoptions.method = BitmapConversionType.HALFTONESCREEN
bitsaveoptions.angle = 45
bitsaveoptions.frequency = 55
bitsaveoptions.resolution = 300
bitsaveoptions.shape = BitmapHalfToneType.ROUND
app.activeDocument.changeMode(ChangeMode.BITMAP,bitsaveoptions);
// THIS IS WHERE I'M HAVING ISSUES- I want to save the file (which at this point is a bmp), with a suffix of 1 in the same folder; and then close the file.
var doc = app.activeDocument;
var docName = doc.name;
docName = docName.match(/(.*)(\.[^\.]+)/) ? docName = docName.match(/(.*)(\.[^\.]+)/):docName = [docName, docName];
var suffix = '_1';
var saveName = new File(decodeURI(doc.path)+'/'+docName[1]+suffix+'.bmp');
function saveFile(app.activeDocument, saveName);

I figured it out, here's for anyone else who is struggling with a similar problem:
var CurrentDLPFile=app.activeDocument
// saves active doc as photoshop file
if (f!=null) CurrentDLPFile.saveAs(f,undefined);
//renames active document to whatever was saved
var CurrentDLPFile = app.activeDocument.name
//assigns the location of the saved psd
var psdPath = activeDocument.path
saveBMP = new BMPSaveOptions();
saveBMP.alphaChannels = false;
saveBMP.depth = BMPDepthType.ONE;
saveBMP.flipRowOrder = false;
saveBMP.rleCompression = false;
saveBMP.osType = OperatingSystem.WINDOWS;
var doc = app.activeDocument;
var Name = doc.name.replace(/\.[^\.]+$/, '');
var Suffix = "1";
var saveFile = File(psdPath + "/" + Name + Suffix + ".bmp");
activeDocument.saveAs(saveFile, saveBMP, true, Extension.LOWERCASE);
activeDocument.close( SaveOptions.DONOTSAVECHANGES );

Image darker when saved than on-screen buffered image

Hi,
Here is my little application. I am trying to simulate an rgb screen look based on image data. ie, the new image is an exaggerated tv look of the original image.
When I try to encode/save a jpeg from my buffered image, the saved image is darker (colours also seem to be different) than what i see in my application frame. I like what I see in the JFrame and would like to have that saved. I am just an artist hack so excuse the cobbled together code. I have also included the original image, the image as it is saved, and an image as a rough approximation of the image in the JFrame.
In the code you will see I have tried different ways to encode the image (commented out)
Any ideas about this issue or how to make this program more sound please let me know.
the code:
http://zukanter.com/javaImageTest/displayImageRGBBuffer.java
the orignal loaded into the appp:
http://zukanter.com/javaImageTest/myPic.jpg
the saved image:
http://zukanter.com/javaImageTest/_003.jpeg
the image as it is in the application window:
http://zukanter.com/javaImageTest/_003Screen.jpg

Hi
My 2c.
I`ve had a quick look at your code and the output and I`m assuming that the vertical RGB lines are what you intended.
Jpeg works in blocks, and averages pixel valiues across them.
If introducing those primaries into the graphic and then compressing it makes it darker that`s likely the result of the primary colours being averaged by the compression algorithm.
You should look at resizing the image first, drawing it onto an offscreen buffer, then doing an overlay (alpha channel) with the primary colors instead, IMHO.

Cant export large satellite image in BMP format

I loaded a satellite image stored in TIFF format 35681x16716 x 24 bits per pixel
I wanted to convert it to BMP but when I want to save as there was no such option why?
There wasn't PNG either. GIMP a free software program was able to load the TIFF and export as PNG
CS5 cant even do that. But GIMP could not export to BMP as it died on export.
So my question is how do I get this to work? How do I export this huge image to BMP?

I wanted to convert it to BMP but when I want to save as there was no such option why?
Because all image formats are constrained in some way and PS in particular will not save/ export anything beyond 32000 pixesl to those legacy formats, even if they may in theory allow more. It simply can't be done.

Graphics to Buffered Image

Hello there.
Ill try to explain this the simplest way possible. Lets say i have a map, and sprites on that map. The map by itself its static, it will only move along as a camera move. Im calling, methods directly in Paint from my applet to draw the map, and draw the sprites. What i am willing to do it, Drawing the map into a separate Graphics or a BufferedImage, so i can draw the map on the final graphics. This would also make i draw the map only once, witch would be good as well, cause actually map drawing is on a loop.
Thanx in advance for any help.
For a better undestanding:
I have a map, and i have sprites, and a window class. Each is drawd by a different class. My Paint method is something similar to this:
public void paint(Graphics g) {
   MapClass.drawMap(g);
   SpriteClass.drawSprites(g);
   WindowClass.drawWindows(g);
}now, this makes me draw the map on the game loop, and if i wanted to move the map around i would have to translate the graphics to move only the map and sprites. However, i belive this could be easyer if i have a separate map for example, and i could use my paint method like this:
public void paint(Graphics g) {
   g.drawImage(MapClass.getMap(), camX, camY, screenX, screenY);
   g.drawImage(SpriteClass.getSprites(), camX, camY, screenX, screenY);
   WindowClass.drawWindows(g);
}So i could control camera movements easy, and i can save the map into memory so i dont have to draw it over and over again. Ive googled into how to create a buffered image from a graphics but couldnt do it. Lets say i have this method doing the paint ( a simple one )
// class Sprites
public void drawSprites(Graphics g) {
    g.drawImage( sprite, spriteX, spriteY, sizeX, sizeY);
}Now, i would have something like that
public BufferedImage getSprites() {
   Graphics g = new Graphics();
   g.drawImage( sprite, spriteX, spriteY, sizeX, sizeY);
   BufferedImage img = new BufferedImage(parms, parms2);
   img = g; // ?
   return img;
}So i could just paint this img on the main graphics, and move it easy, and pheraphs store it in memory.
Thanx for any kind of help.

Webcam capture & save as JPEG image

Hi,
I'm creating an application to capture image via webcam using directshow. I've managed to capture the stream using samplegrabber.
the problem is when I save the grabbed image to a JPEG, the colors are incorrect.
provided the link of the captured image from the webcam http://www.filefreak.com/pfiles/44160/test2.jpg
the right hand side of the image should be brown colored, not blue as in the picture.
I've also test to save as a bmp image, the color are ok.
this is how i save the grabbed webcam frame into a jpeg file
sampleGrabber->GetCurrentBuffer(&bufferSize, (long*)frameBuffer);
//save into jpeg
struct jpeg_compress_struct cinfo;
struct jpeg_error_mgr jerr;
JSAMPLE * image_buffer=NULL;
FILE * outfile;
JSAMPROW row_pointer[1];
int row_stride;
cinfo.err = jpeg_std_error(&jerr);
jpeg_create_compress(&cinfo);
if ((outfile = fopen("test2.jpg", "wb")) == NULL) {
        fprintf(stderr, "can't open %s\n", "test2.jpg");
    return;
image_buffer = (unsigned char*)frameBuffer;
jpeg_stdio_dest(&cinfo, outfile);
cinfo.image_width = videoWidth;
cinfo.image_height = videoHeight;
cinfo.input_components = 3;
cinfo.in_color_space = JCS_RGB;
jpeg_set_defaults(&cinfo);
jpeg_set_quality(&cinfo, 255, TRUE );
jpeg_start_compress(&cinfo, TRUE);
row_stride = videoWidth * 3;
while (cinfo.next_scanline < cinfo.image_height) {
    row_pointer[0] = & image_buffer[cinfo.next_scanline * row_stride];
    (void) jpeg_write_scanlines(&cinfo, row_pointer, 1);
jpeg_finish_compress(&cinfo);
fclose(outfile);
jpeg_destroy_compress(&cinfo);
//end save jpeg

Problem in sending buffered image to remote machine

iam able to capture ithe desktop screen as a buffered image by using buffered image class in java.awt.image.but iam bot able to send that buffered image to remote machine.it is only possible to send some part of that buffered image.but iam not able to transmit the whole buffere image of my desktop.can u help.

Hi,
For this topic you should have a look ( 2004-07-08 The Java Specialists' Newsletter [Issue 091] )
from Dr. Heinz Kabutz. Indeed, the newsletter is quite useful and sometimes also amazing.
I really enjoy reading it.
In this newsletter he is exactly doing what you wanted to know.
He uses an ObjectOutputStream, but compresses the screenshot beforehand as follows:
    import com.sun.image.codec.jpeg.*;
    Toolkit defaultToolkit = Toolkit.getDefaultToolkit();
    Rectangle shotArea = new Rectangle(
        defaultToolkit.getScreenSize());
    ByteArrayOutputStream bout = new ByteArrayOutputStream();
    JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(bout);
    encoder.encode(robot.createScreenCapture(shotArea));
    return bout.toByteArray();Hope that helps

How do i save STACKS of images (e.g. TIFF) as a SINGLE file in IMAQ?

I would like to save stacks of images (movies and time series) as single files (TIFF in particular) but i can only find support in IMAQ for saving single images to single files. Does anyone know how to save STACKS? (As far as i know that is a common feature in most frame grabbers).
I am using a PCI-1408 card for analog acquisition and NI-IMAQ driver in Windows 2000.

Bernhard,
There are no utilities in IMAQ to save image sequences in a single file.
One possible solution, if you aren't trying to compress the images, is to extract the 2D array of pixel intensities and save them as a standard array. You would be able to store as many arrays as you want in a single file.
If you want to compress the images, there are utilities for creating AVI files. I have used a wavelet compression utility that I wrote LV drivers for, also. If you are willing to spend a little money, that might be a good solution. You can contact me at bruce@ammonsengineering if you want to discuss it further.

How do I fix extremely slow rendering with buffered images?

I've found random examples of people with this problem, but I can't seem to find any solutions in my googling. So I figured I'd go to the source. Basically, I am working on a simple platform game in java (an applet) as a surprise present for my girlfriend. The mechanics work fine, and are actually really fast, but the graphics are AWFUL. I wanted to capture some oldschool flavor, so I want to render several backgrounds scrolling in paralax (the closest background scrolls faster than far backgrounds). All I did was take a buffered image and create a graphics context for it. I pass that graphics context through several functions, drawing the background, the distant paralax, the player/entities, particles, and finally close paralax.
Only problem is it runs at like 5 fps (estimated, I havn't actually counted).
I KNOW this is a graphics thing, because I can make it run quite smoothly by commenting out the code to draw the background/paralax backgrounds... and that code is nothing more complicated than a graphics2d.drawImage
So obviously I am doing something wrong here... how do I speed this up?
Code for main class follows:
import javax.swing.JApplet;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.awt.event.*;
import Entities.*;
import Worlds.*;
// run this applet in 640x480

are the parallax images translucent by any chance? The most efficient way to draw images with transparent areas is to do something like this:
     public static BufferedImage optimizeImage(BufferedImage img)
          GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
          GraphicsConfiguration gc = gd.getDefaultConfiguration();
          boolean istransparent = img.getColorModel().hasAlpha();
          BufferedImage img2 = gc.createCompatibleImage(img.getWidth(), img.getHeight(), istransparent ? Transparency.BITMASK : Transparency.OPAQUE);
          Graphics2D g = img2.createGraphics();
          g.drawImage(img, 0, 0, null);
          g.dispose();
          return img2;
     }I copied this from a util class I have and I had to modify it a little, I hope I didn't break anything.
This piece of code does a number of things:
- it allows the images to be hardware accelerated
- the returned image is 100% compatible with the display, regardless of what the input image is
- BITMASK transparent images are an incredible amount faster than translucent images
BITMASK means that a pixel is either fully transparent or it is fully opaque; there is no alpha blending being performed. Alpha blending in software rendering mode is very slow, so this may be the bottleneck that is bothering you.
If you require your parallax images to be translucent then I wouldn't know how to get it to draw quicker in an applet, other than trying out java 6 update 10 to see if it fixes things.

How to save a drawn image in our own format

hai,
i'm developing a designing tool. in that user can draw any type of diagrams. i have to save the drawn image in my own extention... how can i do it. provide me some sample code if u can...

Thanks,
but I am using Image.getScaledImage() to get scaled image(obviously). This returns an Image object. When I call getGraphics() on this object it throws an exception:
Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedOperationException: getGraphics() not valid for images created with createImage(producer) at sun.awt.image.ToolkitImage.getGraphics(ToolkitImage.java:292)Try using createGraphics() instead.
In javadoc i found out that this method can be used only on off-screen image. What is off-screen image?Use BufferedImages, you'll have a lot less problems.
Anyway I can't use this object in ImageIO.write because it requires RenderedImage object which can only be BufferedImage object.
I tried to cast Image to BufferedImage but can't be ... If you need to get your Image painted onto a BufferedImage, you can do it like this:
BufferedImage bi = new BufferedImage(myImageWidth, myImageHeight, BufferedImage.TYPE_INT_RGB);
Graphics2D g = bi.createGraphics();
g.drawImage(myImage, 0, 0, null);

Error-29, Cannot burn a DVD or save a disc image from within FCPX using Mountain Lion

Really stumped on this one.
Running Mountain Lion, freshly downloaded version of FCPX, on a 2009 MacPro with 16 G RAM.
Trying to share a 4 minute movie I edited.
- No problem exporting as a quicktime move...worked fine
- Big problem trying to either burn a DVD, save a disc image, or export to an Apple device.
The progress bar gets about 90% complete, and then it stops and a message window comes up that says:
There was an error burning your disc. The operation couldn't be completed. (DSPPublishing error-29)
Thoughts?

From Crash Analyzer:
DSPPublishing error -29 (Final Cut Pro X)
This error can occur when burning a disc if your menu has incompatible assets.
Suggested Actions
If your menu has a background image, make sure the image is not too large. Try reducing the size of the image and saving it as a JPEG or PNG.
