Graphics2D to Image conversion

I'm writing an isometric strategy game similar to Final Fantasy Tactics or Tactics Ogre.
When I render the frame I have two types of graphics, static and dynamic. The static graphics, well... don't change, and the dynamic do...
Now I'm rendering the static graphics with my tile engine. It renders a 40x40 image to the appropriate x,y. What I want to do is save myself time by not rendering all the tiles every frame, but rather just the first frame and then store that buffer into an object that I have that stores my Images.
The problem now arrises that I have:
g = (Graphics2D)strategy.getDrawGraphics();
//draw static images **LOTS** of g.drawImage()
strategy.show();and I want to store the g as an Image...
How can I do this?

You will have to create an image (either VolatileImage or BufferedImage) and draw your tiles to that image, then draw the image each time you need to.

Need Help in Image Conversion

Hi all
I wonder how these image conversion happens when it comes in the point of converting multiple image in to a single TIFF..i am doing it to the extent resulting in the image creation with file size..The Mystery is i dont have any image when i open the TIFF image...can some one guide me how to handle things...

Hi,
thanks for reply.
But changing in SPRO -> is just the display option.
But the issue that is being faced is with the currency conversion in the query. since the rate for that currecny maintained in tcurr table is a very small value, the conversion is not happening and its displayed as it is in the query output.
also, we cannot go with the option of changing the ratio in tcurr table for this currency, because there are so many dependent objects and then we have to change some logic for all those to incorporate this rates. and our Basis team has mentioned that changing the ratio will not be done because of this.
how do i go about? whether any other methods available?

Image conversion utility

We are trying to find or create a solution for converting any of a set of Adobe files (PSD, AI, PDF, INDD) into JPEG files for each page. Doing it through an API would be preferred, but at this point we are happy to have any starting point to work from.
There is an article on the Developer Network website:

Controlling Image Conversion quality from Word to RoboHelp 8

I cannot find settings that will control image quality when converting Word documents to online help files by means of RoboHelp.
My problem is that screen captures, which were inserted as PNG or bitmaps, are reproduced with what looks like GIF or JPEG quality in the online help. I want better quality.
I read that for Famemaker, there are image conversion settings that enable one to preserve full, lossless (screen) resolution during the conversion.
Is there a way to do this for conversion from Word 2007 documents to RoboHelp 8?
If not, perhaps RoboHelp 9?
Much obliged.

I am importing the Word documents into RoboHelp HTML version 7.0. I did the following experiment:
I imported a document with images containing vector text (the images are in Microsoft Office Object format) from Word 2007 to RoboHelp HTML 7.0, I got poor quality (badly formed text / aliasing). I presume this comes from the rendering and compression performed by the import function. I also saw JPEG artifacts in the raster (screen captures) images of the kind visible at very high compression ratios and which were not visible in the original.
When I insert the very same images, saved as PNG format at screen resolution, directly into RoboHelp HTML 7.0, I get good quality.
It seems that the Import from Word function is rendering and converting the images to a compressed format without preserving sufficient quality.
My questions are:
Is there a preferred format for the embedded images in Word for better import to RoboHelp, especially when the images contain (vector) text?
Are there accessible configuration parameters for the Import from Word function, that can control the rendering, and/or the quality level of JPEG compression, and/or give a choice between compressed and uncompressed images.
How can I access those parameters?
Thanks!

High Resolution HTML to Image Conversion

I am rendering a html file using JEditorPane and painting the pixels to a BufferedImage object. How can I make a higher resolution than 72 dpi.
Here is my current program
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.*;
import javax.imageio.ImageIO;
import javax.swing.JEditorPane;
public class Main {
    public static final double WIDTH_INCHES = 11 - 0.5 - 0.5;
    public static final double HEIGHT_INCHES = 11 - 0.5 - 0.5;
    public static final double DPI = 72;
    public static final int WIDTH_PIXELS = (int) (WIDTH_INCHES * DPI);
    public static final int HEIGHT_PIXELS = (int) (HEIGHT_INCHES * DPI);
    public static void main(String[] args) throws FileNotFoundException,
            IOException {
        StringBuilder htmlCode = new StringBuilder();
        FileReader htmlFileReader = new FileReader("test.htm");
        BufferedReader htmlFileBufferedReader =
                new BufferedReader(htmlFileReader);
        String aLine;
        while ((aLine = htmlFileBufferedReader.readLine()) != null) {
            htmlCode.append(aLine + "\n");
        JEditorPane editorPane = new JEditorPane("text/html",
                htmlCode.toString());
        editorPane.setMaximumSize(new Dimension(WIDTH_PIXELS, HEIGHT_PIXELS));
        editorPane.setSize(new Dimension(WIDTH_PIXELS, HEIGHT_PIXELS));
        editorPane.setBackground(Color.WHITE);
        editorPane.setPreferredSize(new Dimension(WIDTH_PIXELS, HEIGHT_PIXELS));
        BufferedImage image = new BufferedImage(WIDTH_PIXELS, HEIGHT_PIXELS,
                Image.SCALE_SMOOTH);
        editorPane.paint(image.getGraphics());
        ImageIO.write(image, "png", new File("test.png"));
}How can I make this program to make a better resolution image?

I was profiling the application and found that iText was copying the whole image and running transparency checks for the 8.5 by 11 that I was doing at 72x4 dpi.
I found a way to do it more efficiently and it happens to take advantage of the vector text.
I used the PdfContentByte.createGraphicsShapes method to get a PDF Graphics2D object and I painted to that instead of painting to the java.awt.image. I did this in combination with disabling double buffering on the JEditorPane
This is my working code example
import com.lowagie.text.*;
import com.lowagie.text.pdf.*;
import java.awt.Dimension;
import java.awt.Insets;
import java.io.*;
import java.util.Date;

Pages to Image conversion

1.Is there any efficient way of exporting or converting a Pages file to an image file e.g. .jpg? Has anyone built a patch for this or can a script be used. It's very frustrating as we used to use the AW Suite for this conversion. A number of people have suggested we use print to pdf and then use Image Preview as the converter, but it will not convert a multi page file (will only convert 1 page @ a time) this is very tedious and requires too many steps. Does anyone know a quick way of doing this?
2. Is there any efficient way of upgrading AW Draw files as AW is being phased out?

If your Draw documents doesn't contai tables or spreadsheets, you may look at EasyDraw.
As I often wrote, Numbers is a perfect tool to import AW Draw documents.
I hope that Apple will write the needed importer tool.
If they don't, I wiil write a script to do that when Numbers will be scriptable.

Swing to Image Conversion

Anybody know how to go about converting a swing container (such as JFrame) into an image like JPEG or PNG? Also, is there any library to allow conversion into PDF?
Thanks,
Mehul.

Ohh yeah..that's amazing.
Another issue:
I'm using a 3rd party charting software in which they have a Chart class that extends from JLayeredPane. Now this Chart component has other subcomponents like Legend and ChartArea. The Legend and ChartArea classes extend from JComponent. The ChartArea includes 2 things: a drawing rectangle and a plotting rectangle. The plotting rectangle is a part of the drawing rectangle. The drawing rectangle also includes other stuff such as the axes, some margins/boundaries etc.
Now, what I am trying to do is to provide the ability for a user to select a portion of the drawing rectangle by dragging his mouse. To do this, I create a chart class extends from Chart and then provide a paintComponent method in which I adjust my coordinates so that they are for the ChartArea rather than Chart. But, here's the problem I'm seeing: Without calling setXOR in paintComponent, when I drag my mouse on the ChartArea, my selection box is visible only outside the plotting rectangle (but still within the drawing rectangle)..the rest of the plotting area also gets selected, but my selection there gets hidden behind the plotting area...so I can't really see what region i've selected. If I do call setXOR, then I can see the entire selection box on top of the plotting rectangle, but my plotting rectangle gets a little disoriented and discolored when I click on it (to do the selection).
I'm not able to understand why I'm seeing this behavior. Any ideas?
Thanks.

How to control canvas color with preview/automator image conversion

However, some images will end up having a black canvas while others will have a white canvas post-conversation. I would like all converted images to have a white canvas. Is there a way to ensure this?

Assistance with image conversion program.

hello,
I am relatively new to java so have already requested some help within the "new to java" section of the forum but wondered if it might be more appropriate to post my question in here? anyway...
I am trying to write a program which will convert a color image into a greyscale image. I have managed to get my code to compile but the output i receive is not what i expected. When running the conversion it produces a black image. The idea is to create an array, use pixelgrabber to place each pixel into this array, get the red, green, and blue values, convert into greyscale, add these coverted pixels to an array and make a new image from these. My code is below:
class SaveGreyMenuListnr implements ActionListener {
private ImagePanel panel = null;
SaveGreyMenuListnr (ImagePanel pn) {
panel = pn;
public void actionPerformed (ActionEvent ae) {
Image displayed = panel.getDisplayImage();
int width = displayed.getWidth(panel);
int height = displayed.getHeight(panel);
int pixels[] = new int[width*height]
PixelGrabber pg = new PixelGrabber(displayed, 0, height, width, height, pixels, 0, width);
try{
pg.grabPixels();
} catch (InterruptedException e) {
System.err.println("interrupted waiting for pixels");
for (int i = 0; i < (width*height); i++){
Color myColor = new Color(pixels);
int Red = myColor.getRed();
int Green = myColor.getGreen();
int Blue = myColor.getBlue();
double temp = 0.56 * (double)Green + 0.33 *(double) Red + 0.11 *(double) Blue;
myColor = new Color((int)temp,(int)temp,(int)temp);
int compressedInt = myColor.getRGB();
pixels[i] = compressedInt;
Image image = panel.getToolkit().createImage(new MemoryImageSource(width,height,pixels,0,width));
panel.setDisplayImage(image);
panel.repaint();
I think an issue is arising when using the getRed getGreen and getBlue methods... for example If i request System.out.println(Red); then a stream of 0's are shown on the command line.
Not 100% sure if this is the issue or if it is further back in my code. Any help would be greatly appreciated
cheers

Just looked at your code again. Did you mean int,not
long?He wanted an unsigned int (which of course doesn't
exist in Java) and if you look at his original code it
was returning long.Well, it's not so much that I wanted an unsigned int, it's just that the data was stored as a 32 bit unsigned integer. Since the data represented numbers with a range of 0 to 2^32 - 1, the range exceeded what I could put in a Java int, thus I need to stuff it in a long - well, that was my reasoning anyway.
Thanks for the nio tip, I'd not looked into that stuff and really should.

Thanks much for the code -
