Transform jpeg image to binary coded image

how to transform jpeg image to binary coded image? using which properties? thanks .

well, I dont think so. but what exactly do you need, transforming it into bits or bytes?
well, I have no time to do the program for you, but this is the idea:
FileInputStream inputF=null;
File imageF;
byte content [];
try {
    imageF=new File ("The image path");
    content=new byte [(int) imageF.length ()];
    inputF=new FIleInputStream ("the image path");
    inputF.read (content);
} catch (Exception E) {
}and thats all to have a byte array with the bytes of the image.

Converting a binary string into a JPEG image in Crystal Reports 2008

Hi Gang
Iu2019m having problems converting a binary string into an image in Crystal Reports 2008
I have JPEG images stored in ECC. ECC stores the data in binary format.
Iu2019m using the ECC function module SKWF_PHIO_CONTENT_ACCESS_GET to retrieve the data. This function module has an export table, FILE_CONTENT_BINARY, which returns several lines of data. Each line contains a maximum of 1,024 characters.
When I drop the T_ FILE_CONTENT_BINARY.LINE field into my Crystal Report detail section, I wind up with a report that displays all the lines in FILE_CONTENT_BINARY table. (in my case, 19 lines are displayed.)
I created a formula to collect all the data into a single string.
whileprintingrecords;
stringvar data:= data & {SKWF_PHIO_CONTENT_ACCESS_GET.T_FILE_CONTENT_BINARY.LINE}
I added the formula to the detail section and itu2019s doing a great job collecting the data.
I then inserted a picture object in the report footer, opened the format editor, navigated to the u201Cpictureu201D tab, and inserted a formula for the u201Cgraphics locationu201D.
whileprintingrecords;
stringvar data:=data;
data
My clever idea turned out to be a disappointment . . . . my picture object is blank.
Does anyone have a solution for converting a binary string into a JPEG image?

Save the JPEG in a format CR supports. Refer to the help file for the file types.

Scaling Binary JPEG images

Sorry if this is in the wrong forum.
I am extracting JPEG images stored in a blob field in a DB. I can obtain the bytes of the JPEG in a couple different ways but I have had no luck in scaling the images.
I need to simple scale the image, and then return the new image preferably in a byte[] or something that I can convert to a byte[].
I have come accross several past post, and at times seems to work. None of them actually return an image or errors so I am not sure where it fails.
I tried a modified version of the following which was an example on making thumbnails out of a larger image.
Here's the url to that example
http://developer.java.sun.com/developer/TechTips/1999/tt1021.html
After modifying the code, when I went to test I recieved a weird error in a log file that basically said something could not use :0 which is refering to my monitor.
This is and will be used in a Linux env, but does not or should not invlove X in anyway. I have come accross other example that talk about a frame.addnotify() method that is supposed to resolve this issue when not outputing to a monitor.
After adding that, the error is not there, but neither is my scaled image.(which wasn't there before either)
If this sound strange, that's beacuse I am creating a custom Generator object. Generator being a Servlet created by Macromedia to generate Flash movies and etc. on the fly.
For some reason in the API it lacks the ability to scale a JPEG image. Yet to be able to put the image into Flash, I must get the image's byte[].
Please help, I have played around with this one for some time now, and have tried more things than I could document here.
Any assistance is greatly appreciated!

How to load a jpeg image in to a database from a flex2 app

Hi,
how ouwld I browse the local fie system, select a jpeg image
and then save
it to a database using flex2?
Anybody know of some sample code that I can look at?
Thamls

Hi Thamis,
Take a look at the flash.net.FileReference class here:
http://livedocs.macromedia.com/flex/2/langref/index.html
This is the built in Flash support for file upload. You'd
handle the upload with a servlet/jsp/etc. server-side component to
save it to disk or as binary data in a database.
Best,
Seth

How to store jpeg images in SQL server using NI database Connectivity Toolset. Can anyone please help me in this regard.

Please tell how to store jpeg images in SQL Server using NI Database Connectivity Toolset.

http://www.w3schools.com/sql/sql_datatypes.asp
You setup a field as BLOB and store the binary of the picture there. Depending on the database it can be called differently as you can see in the link, in SQL server there's even a Image datatype.

Problem displaying CMYK jpeg images

I have a problem with a CMYK jpeg image.
I know that about supported JPEGs in JRE - JCS_CMYK and JCS_YCCK are not supported directly.
And I found here how to load the image:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4799903
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5100094
I used both the suggestions described to load it, but when the image is displayed the colors are wrong, are very different from the one displayed in PhotoShop, for example.
Any suggestion are very appreciated. If it's necessary i can send you the image.

The loading process It takes about 10 seconds, and every repaint it takes the same time.The painting yes, the loading no. It shouldn't take much more time to load the image then an ordinary JPEG. In particular, your now using a "natively accelerated" JPEG image reader, so it should take less time on average to load any JPEG. 10 seconds is absurd. Are you sure your not including the drawing time in that figure?
- Another problem: JAI-ImageIO is not available for MAC OS X platform.This is somewhat true. You can take the imageio.jar file and package it together with your program (adding it to the class path). This will give you most of the functionality of JAI-ImageIO; in particular the TIFFImageReader. You just won't be able to use the two natively accelerated ImageReaders that comes with installing.
Right now, you're using the accelerated CLibJPEGImageReader to read the image. You can't use this image reader on the MAC, so you have to take the approach mentioned in the 2nd bug report you originally posted (i.e. use an arbitrary CMYK profile).
The conversion is too long more than 30 seconds.The code you posted could be simplified to
BufferedImage rgbImage = new BufferedImage(w,h,
            BufferedImage.3_BYTE_BGR);
ColorConvertOp op = new ColorConvertOp(null);
op.filter(cmykImage,rgbImage);But again, 30 seconds is an absurd value. After a little preparation, converting from one ICC_Profile to another is essentially a look up operation. What does,
System.out.println(cmykImage.getColorModel().getColorSpace());print out? If it's not an instance of ICC_ColorSpace, then I can understand the 30 seconds. If it is, then something is dreadfully wrong.
the RGB bufferedImage that i get after the transformation when it is displayed is much more brightThis is the "one last problem that pops up" that I hinted at. It's because some gamma correction is going on in the background. I have a solution, but it's programming to the implementation of the ColorConvertOp class and not the API. So I'm not sure about its portability between java versions or OS's.

There are two images in that zip file. I have no problems reading the one called "lossless.jpg". It's a 16-bit grayscale image that's completely black. The one called "test.jpg" throws an exception. Is this what you're getting? I'm using JAI-ImageIO 1.1
is there any website has good tutorial about lossless jpeg image. what
is point transform in lossless jpeg ? what old pseudo lossless jpeg ?
what is equivalent for that in java ? In addition to describing normal jpeg encoding, the jpeg specification also describes what's called "lossless jpeg" encoding. Lossless jpegs - as described in the original specification - are obsolete. No common application can open them. It doesn't help that the png format (also lossless) provides much smaller file sizes then lossless jpeg's.
Both of the jpegs in that zip file are lossless jpegs. Incidently, I can't open them up with Irfanview or Adobe Photoshop CS4 (wich says alot). And I can only read "lossless.jpg" with JAI-ImageIO while the other one throws an IOException. By using lossless jpegs, the user cripples portability.
JPEG-LS is different from lossless jpeg. In fact, it was meant to replace lossless jpegs. While not actually lossless, jpeg-ls is described as a "near lossless" compression. I believe the files have a +.jls+ extension instead of a +.jpg+ one. While not obsolete (I think), JPEG-LS is not widely used. Using it can still cripple portability.
The JPEG2000 format also has a "lossless" mode, that again, is not widely used. Using it can still cripple portability. JPEG2000 files have a +.jp2+ extension.
Lastly, I don't know what you mean by this question
what is point transform in lossless jpeg?PS: I have no problems reading a lossless jpeg or a jpeg-ls that I write with JAI-ImageIO. So maybe there's something wrong with "test.jpg" in the zip file?

After rotate, display of large JPEG images very slow.

I am loading and displaying images using JAI and Java2D.
When I load a large grayscale JPEG image (300 dpi, letter size), it displays fine.
After a rotate, the next display is incredibly slow.
Source is a RenderedImage loaded from a JPEG file using:
     FileSeekableStream ss = new FileSeekableStream(file);
     ImageDecoder dec = ImageCodec.createImageDecoder("jpeg", ss, null);
     RenderedImage source = dec.decodeAsRenderedImage(curPage);
I create a scaled image using:
     interp = Interpolation.getInstance(Interpolation.INTERP_BILINEAR);
     ParameterBlock params = new ParameterBlock();
     params.addSource(source);
     params.add(xZoom); // x scale factor
     params.add(yZoom); // y scale factor
     params.add(0.0F); // x translate
     params.add(0.0F); // y translate
     params.add(interp); // interpolation method
RenderedOp image3 = JAI.create("scale", params);
And display inside the paintComponent() method of my JPanel-derived class using:
     AffineTransform transform = new AffineTransform();
     transform.translate(shiftX, shiftY);
     Graphics2D G2d = (Graphics2D)g.create(); //copy g
     G2d.drawRenderedImage(image3, transform);
If I add a rotate step after the scale:
     ParameterBlock paramsR = new ParameterBlock();
     paramsR.addSource(source);
     paramsR.add(TransposeDescriptor.ROTATE_90);
     // Create an operator to turn image.
     source = JAI.create("Transpose", paramsR, null);
Then the next display for a 300 dpi 8 bit grayscale JPEG file can take up to 60 seconds.
The bulk of the elapsed time is inside: Graphics2D.drawRenderedImage(image3, transform);
Any ideas what I am doing wrong here?
I am relatively new to using Java Advanced Imaging.
Thanks,
T.J. Brown

Sorry, a correction.
The file is actually JPEG-compressed data inside a TIFF file.
So the decode step uses:
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", ss, null);
JPEG inside a JFIF file is much faster.
Thanks,
T.J. Brown

I cannot erase alias JPeg images on a memory card so that it will not accept any more which I try to load onto it, yet there are no actual images available if I click on any of them. The error message states that one or more cannot

Cannot delete aliases for JPeg images on a lumix camera memory card even selecting individual images anjd trying to move to trash -error35 one or more items cannot be found. No image available on clicking or if card put back into camera-"no images to disply" Yet if try to add more images, message that card is full! Any suggestions?

Deleting from iPhoto or image capture after import should be fine and shouldn't cause any issues. Deleting from the folder view of finder, can cause issues as the camera can the image is still there. You can try emptying the trash on your mac if you deleted them via the finder, as although you've deleted it, it's only marked as trashed and not actually deleted until you empty the trash - ie it won't relieve the space taken by the files.
If your still having issues after you try this, you may be best formating the memory card. This will wipe all data on it though, so make sure you do copy anything off that yo u want to keep! Format from the camera, so that choosing the format>erase all option from the menu of most cameras.

hedger,
How do you expect anyone to help when we don't know a darned thing about the file, abut your setup, exact version of Photoshop and your OS, machine specs, etc.?
BOILERPLATE TEXT:
Note that this is boilerplate text.
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
etc.,
someone may be able to help you (not necessarily this poster, who is not a Windows user).
a screen shot of your settings or of the image could be very helpful too.

How to insert a pdf or jpeg image into a blob column of a table

How to insert a pdf or jpeg image into a blob column of a table

Hi,
Try This
Loading an image into a BLOB column and displaying it via OAS
The steps are as follows:
Step 1.
Create a table to store the blobs:
create table blobs
( id varchar2(255),
blob_col blob
Step 2.
Create a logical directory in the database to the physical file system:
create or replace directory MY_FILES as 'c:\images';
Step 3.
Create a procedure to load the blobs from the file system using the logical
directory. The gif "aria.gif" must exist in c:\images.
create or replace procedure insert_img as
f_lob bfile;
b_lob blob;
begin
insert into blobs values ( 'MyGif', empty_blob() )
return blob_col into b_lob;
f_lob := bfilename( 'MY_FILES', 'aria.gif' );
dbms_lob.fileopen(f_lob, dbms_lob.file_readonly);
dbms_lob.loadfromfile( b_lob, f_lob, dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
Step 4.
Create a procedure that is called via Oracle Application Server to display the
image.
create or replace procedure get_img as
vblob blob;
buffer raw(32000);
buffer_size integer := 32000;
offset integer := 1;
length number;
begin
owa_util.mime_header('image/gif');
select blob_col into vblob from blobs where id = 'MyGif';
length := dbms_lob.getlength(vblob);
while offset < length loop
dbms_lob.read(vblob, buffer_size, offset, buffer);
htp.prn(utl_raw.cast_to_varchar2(buffer));
offset := offset + buffer_size;
end loop;
exception
when others then
htp.p(sqlerrm);
end;
Step 5.
Use the PL/SQL cartridge to call the get_img procedure
OR
Create that procedure as a function and invoke it within your PL/SQL code to
place the images appropriately on your HTML page via the PL/SQL toolkit.
from a html form
1. Create an HTML form where the image field will be <input type="file">. You also
need the file MIME type .
2. Create a procedure receiving the form parameters. The file field will be a Varchar2
parameter, because you receive the image path not the image itself.
3. Insert the image file into table using "Create directory NAME as IMAGE_PATH" and
then use "Insert into TABLE (consecutive, BLOB_OBJECT, MIME_OBJECT) values (sequence.nextval,
EMPTY_BLOB(), 'GIF' or 'JPEG') returning BLOB_OBJECT, consecutive into variable_blob,
variable_consecutive.
4. Load the file into table using:
dbms_lob.loadfromfile(variable_blob, variable_file_name, dbms_lob.getlength(variable_file_name));
dbms_lob.fileclose(variable_file_name);
commit.

Converting a pdf document to a jpeg image C#

HI There,
How can I convert a pdf document to a jpeg image using c sharp? I need to do this on a web application. If someone can help me out with some code that would be great.
Sean - thanks in advance

The information provided by Aandi is unfortunately out of date. The Adobe PDF Library is obtained through Datalogics and has a JNI, Java, and .NET interface available. Additionally while the Adobe PDF Library with the .NET interface would provide the functionality you seek it is overkill.
PDF2IMG from Datalogics has a COM component available that can be accessed via C# to convert PDF to most image formats.

To make this so it will work on the server, it will need to be recoded so that it uses the command line only - no GUI.
What is it exactly that PinkChartFrame is generated an image of? What does it do? (OK probably 'generate a chart') But what APIs does it use (JFreeChart or such)?
