Return Image from JNI
hi....
sorry.. someone knows if i can get a icon or image from native code
i'm tried to do this but i dont know so much c++.
i can return int values and String values but image u Object from C++
i think is diferent someone knows how to do it
thans and please helpme on this...
Generally, very very generally, on these forums and others, people often asks how to do XYZ in a coding level. And at the same time, you often give straight reply to them questions however complex or brittle tasks they are. We see very few occasion in which you interrogate design level viability or soundness of the intention those questions imply.
I think wise reply should often ignore the question itself and instead ask its application level objective or circumstance. Then you may give much better solution than straight answer to the original question.
Q: How to kill mosquitos in the room without harming my baby?
Straight Answer: Use drug ABC and tool PQR.
Wise Ansewer: Forget killing them. Buy and install good screens.

Trouble returning String from JNI method
I'm a JNI newbie who is going through the SUN online book on JNI and have put together the 2nd program example (right after "helloworld"), but it is not working right. It is supposed to prompt you for a string, then returns the string that you type in. Right now it compiles without error, but it returns only the first word that I type, not the whole sentence. What am I doing wrong?
Here's the code:
Prompt.java
package petes.JNI;
public class Prompt
private native String getLine(String prompt);
static
System.loadLibrary("petes_JNI_Prompt");
public static void main(String[] args)
Prompt p = new Prompt();
String input = p.getLine("Type a line: ");
System.out.println("User typed: " + input);
}petes_JNI_Prompt.h
/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class petes_JNI_Prompt */
#ifndef _Included_petes_JNI_Prompt
#define _Included_petes_JNI_Prompt
#ifdef __cplusplus
extern "C" {
#endif
* Class: petes_JNI_Prompt
* Method: getLine
* Signature: (Ljava/lang/String;)Ljava/lang/String;
JNIEXPORT jstring JNICALL Java_petes_JNI_Prompt_getLine
(JNIEnv *, jobject, jstring);
#ifdef __cplusplus

#include "petes_JNI_Prompt.h"
JNIEXPORT jstring JNICALL Java_petes_JNI_Prompt_getLine
(JNIEnv *env, jobject this, jstring prompt)
char buf[128];
const jbyte *str;
str = (*env)->GetStringUTFChars(env, prompt, NULL);
if (str == NULL)
return NULL; /* OutOfMemoryError already thrown */
printf("%s", str);
(*env)->ReleaseStringUTFChars(env, prompt, str);
// assume here that user will ty pe in 127 or less characters
scanf("%s", buf);
return (*env)->NewStringUTF(env, buf);
}Thanks in advance!
/PeteOK, I have something that works now by substituting fgets for scanf. I have two other questions:
1) Do I need to free the memory created in buf? Will it allocate memory every time the method is run? Or will it allocate only once on creation, and so is no big deal?
2) A minor question: When I run this program in eclipse, the prompt string is displayed in the console only after the input string is entered and displayed. It works fine when I run it from the command line however. I have a feeling that this is a problem with how Eclipse deals with native methods and perhaps nothing I can fix. Any thoughts?
Thanks
Pete
Addendum, the updated code:
#include <jni.h>
#include <stdio.h>
#include "petes_JNI_Prompt.h"
JNIEXPORT jstring JNICALL Java_petes_JNI_Prompt_getLine
(JNIEnv *env, jobject this, jstring prompt)
char buf[128];
const jbyte *str;
str = (*env)->GetStringUTFChars(env, prompt, NULL);
if (str == NULL)
return NULL; /* OutOfMemoryError already thrown */
printf("%s", str);
(*env)->ReleaseStringUTFChars(env, prompt, str);
//scanf("%s", buf);
fgets(buf, 128, stdin);
return (*env)->NewStringUTF(env, buf);

This is really interesting!!!
I initially designed my JNI function to create a Java Object and then return this object back to Java. This worked fine if this function was only called 1 or 2 times. The JVM would crash on the 3rd time!!!
So, I changed the code to have the object created from Java and pass it into C. I can call this function any times without crash JVM.
Anyone know something about this? Thanks!Sorry, here's some detail:
I use JDK1.3 on Win2k. The C compiler is cl.exe from DevStudio98. Here's the compile command:
cl -nologo -Zi -dll -IC:\java\jdk1.3\Include -IC:\java\jdk1.3\Include\win32 -IC:\DevStudio98\VC98\INCLUDE -I.\include /DWIN32 /DDEBUG -LD fccCheck.c javaOperations.c -FefccCheck.dll /link .\lib\ceclnt.lib
Thanks for your help! -
Returning values from JNI functions to Java
I have a JNI function which returns a "jstring" to the calling Java function.
I need also to return 2 byte values.
Can I return them all...? if so, how?I have a JNI function which returns a "jstring" to the
calling Java function.
I need also to return 2 byte values.
Can I return them all...? if so, how?"Also"? Then you do the same thing as if you were returning two different types in java only code, you wrap it in an object. -
MII doesn't return images from copied projects
We are using MII 12.2.6.44 and when I make a copy of the existing project, the images cannot be found on the copy. But I'm sure, that they are on the given path, I receive the message:
404 Not Found
SAP NetWeaver Application Server
Error: Requested file /path/path/someimage.png does not exist.
SAP Technology Troubleshooting Guide
Details:
No details available.
Sometimes I have to wait hours to have the pictures loaded, sometimes it is not recovered after days... Is there some "flush" function or something, that I could invoke? Because it is very annoyinghi,
unfortunately this didn't solve my problem, I right-mouse-clicked on the "Web" tab on the "WEB" directory, then "Publish", but I still don't see the icons
EDIT: it works in IE, but not works in FF
EDIT2: okay, maybe I have to restart the browser thankx -
Return an Image from a subclass to a graphics class
Hello
I'm wondering how to return an Image generated by one class to a class which works as a graphics class. The graphics class is run from a main class. Let me make up a schedule:

Problem loading images from a return value of a function
hello, I write because I uin problem in loading images from a return value of a function.
I created a database with a field "image" of type string, where I put the physical address of the image. I have written like this: {__DIR__ }foto.jpg
Place the code, so you understand better
function imageViewImage(): javafx.scene.image.Image {
connetti();
lass.forName(driverName);
con = DriverManager.getConnection(url,user,"");
stmt = con.createStatement();
var richiesta:String = "SELECT image from viaggio WHERE id_viaggio=7";
rs1 = stmt.executeQuery(richiesta);
var result :String;
rs1.next();
risultato = rs1.getString("image");
JOptionPane.showMessageDialog(null, result);
var imagez = Image{
url:"{result}";
return imagez;
The image is in the source code package
First I connect to the database, run the query and I take the contents of the image.
Can anyone help me?
Is right to put in the database {__DIR__} foto.jpg or do I put only foto.jpg?Hello unkus_nob,
I would rather suggest you to save only filename of that image like "foto.jpg" in database. And just concat it with the String variable containing "{__DIR__}".
Actually the javafx compiler converts the {__DIR__} to the existing class directory path something like : "jar:file:/..../".
var currentDir ="{__DIR__}";
risultato = "{currentDir}{rs1.getString("immagine"})";
var image = Image{
url:risultato
return image;--NARAYAN G. -
If I barrow an image from iPhoto, that is drag it to another file or the desktop it seems to half disappear. It still shows until I try to enlarge it then I get a triangle exclamation mark in the enlarged field, once I return to Photos or an Album it is there. However it can no longer be dragged into another file. How can I recover these images? Is there a better way to duplicate a image to locate in outside of iPhoto?
I never had this problem in previous versions of iPhoto.The ! turns up when iPhoto loses the link to the original file.
What version of iPhoto? Assuming 09 or later...
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

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));

Error While loading a image from database
Purpose
Error While loading the Image from the database
ORA-06502: PL/SQL : numeric or value error:Character string buffer too small
ORA-06512: at "Sys.HTP" ,line 1480
Requirement:
I am developing the web pages using PSP(Pl/sql Serverpages) . I have a requirement to show a image in the webpage. I got the following procedures from the oracle website.
I have created the following table to store the images
create table DEMO
ID INTEGER not null,
THEBLOB BLOB
And I also uploaded the Images. Now I am try to get a image from the table using the following procedure .But I am getting the error message line 25( htp.prn( utl_raw.cast_to_varchar2( l_raw ) );) .at it throws the following error messages
ORA-06502: PL/SQL : numeric or value error:Character string buffer too small
ORA-06512: at "Sys.HTP" ,line 1480
Procedure that I used to get the image
create or replace package body image_get
as
procedure gif( p_id in demo.id%type )
is
l_lob blob;
l_amt number default 30;
l_off number default 1;
l_raw raw(4096);
begin
select theBlob into l_lob
from demo
where id = p_id;
-- make sure to change this for your type!
owa_util.mime_header( 'image/gif' );
begin
loop
dbms_lob.read( l_lob, l_amt, l_off, l_raw );
-- it is vital to use htp.PRN to avoid
-- spurious line feeds getting added to your
-- document
htp.prn( utl_raw.cast_to_varchar2( l_raw ) );
l_off := l_off+l_amt;
l_amt := 4096;
end loop;
exception
when no_data_found then
NULL;
end;
end;
end;
What I have to do to correct this problem. This demo procedure and table that I am downloaded from oracle. Some where I made a mistake. any help??
Thanks,
NatsHi Satish,
I have set the raw value as 3600 but still its gives the same error only. When I debug the procedure its throwing the error stack in
SYS.htp.prn procedure of the following line of code
if (rows_in < pack_after) then
while ((len - loc) >= HTBUF_LEN)
loop
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1, HTBUF_LEN);
loc := loc + HTBUF_LEN;
end loop;
if (loc < len)
then
rows_in := rows_in + 1;
htbuf(rows_in) := substr(cbuf, loc + 1);
end if;
return;
end if;
Its a system procedure. I don't no how to proceed .. I am really stucked on this....is their any other method to take picture from the database and displayed in the web page.....???? any idea..../suggesstion??
Thanks for your help!!!. -

i am unable to email images from my camera roll. the image gets "stuck". cannot insert email address or subject line. cannot cancel... return to camera roll.
what to do. i tries taking new picture and sending it in an email... same thing... gets "stuck "
Waht to do ?Hello lohmann8,
Thank you for providing so much detail about the issue you are experiencing with emailing photos from the Camera Roll.
The first thing I recommend is quitting and relaunching the applications on your iPhone:
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
You can find the full article here:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
If you are still seeing the same issue after quitting and relaunching the Photos and Camera app, I recommend restarting your phone and then resetting if it's still not working:
Restarting your device
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
You can find the full article here:
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
If the issue persists, the last thing I recommend is backing up and restoring your iPhone:

Pasting Image from Mac clipboard to Java Based Application.
Hi,
I am working on "iMac 10.2.7". I need to paste an image from other
application using "Java version 1.4.1". I am trying to retrieve the image
from the system clipboard after it is copied from some other application. I
am pasting the code which illustrates my requirement. It works fine on
windows. But does not work on Mac.
On Mac it does not cross the supported data flavor check
(clipData.isDataFlavorSupported(DataFlavor.imageFlavor) where clipData is
the Transferable object). It seems Mac has some InputStream instead of Image
in the clipboard when some image is copied. I tried to read that InputStream
using ImageIO.read(java.io.InputStream). But that is also returning null.
Thanks
Santanu

Haven't tested them, so don't no how good they are, nor how easy they are to use on multiple platforms. -
I havent used flash in a couple years and i'm feeling a
little lost (not that i knew what i was doing before!) I am however
determined and can understand the code, i just am a little
overwhelmed.
I'd like to tell a movie clip to look into a specific folder
(via url or whatever) and load all images from that folder into the
movie clip. I do not want to have to give the movie the exact
address of each image, as they files may change / be added to over
time.
i know in AS3 i have to use the loader class and then the
addChild to put the loaded stuff into the movie (and thats all i
know), but i just dont know how to get all available images
blindly. any help? please and thank youYou have the right info for the Loader and addChild part.
But I'm afraid you can't use flash to request a directory
listing on your server directly. You can have a script on your
server return the directory listing to flash after the script
performs a directory listing (e.g. php).
Other than that approach (using serverside scripting)...
You could have all the images with a common naming convention
and a numeric suffix and just keep loading in turn until you
encounter a loading error (which your code is set up to
detect).....
e.g. image1.jpg, image2,jpg etc
or:
You could set up some manually coded xml to point to the urls
of each image etc. It seems you want to avoid this though. (This is
pretty much the same idea as the server side scripting except that
instead of using scripting you create the data by 'hand' as xml). -
How can I get the part image from a rectangle region?
hi,
I'm trying to draw a rectagle region on a picture with mouse and crop it. but the rectangle is not vertical along x-axis.that is to say, there is a angle between x-axis and the base of the rectangle. I don't know , how can I do it. Can someone give me some tip or some java-code. Thank you very much in advance.I completely misunderstood your question. As I read it again it seems clear and straight-forward. I'm sorry. Let's see if this is closer.
