Drawing text in a jpeg image

Hi,
I want to draw a string in a jpeg image file.The file will contain only that string.Anybody can help me suggesting the best way or any available program is there for it.
Thanks in advance.

You can use the image functions in PHP to get the size of JPEG, GIF, PNG, SWF, TIFF and JPEG2000 images, and if you have the GD library (available at http://www.boutell.com/gd/) you will also be able to create and manipulate images.

Can someone help me with drawing text and a custom image in cocoa?

I am trying to learn how to draw, and when I look at the tutorial, instead of getting straight to the point on how to draw text at a coordinate, it talks about the concepts of how to draw. I get that, but exactly what methods and what objects should I use?
For instance, the java code:
+public void drawComponent(Graphics g){+
+Graphics2D g2 = (Graphics2D) g;+
+g2.drawString("Hello, World!", 10, 20);+
draws the good old "Hello, World!" on a line starting 20 pixels down and 10 pixels across. How would I do the same in objective-c in a customized view? Based on the tutorial, I need specify the code in the
+- (void)drawRect: (NSRect) rect+
method.
Also, how would I draw a picture(.gif and .png format)?

Here's a very basic example:
- (void)drawRect:(NSRect)rect {
// draw text
NSString *myString = @"Hello World";
NSFont *font = [NSFont boldSystemFontOfSize:24];
NSColor *color = [NSColor blueColor];
NSDictionary *attrs = [NSDictionary dictionaryWithObjectsAndKeys:
font, NSFontAttributeName,
color, NSForegroundColorAttributeName,
nil];
[myString drawAtPoint:NSMakePoint(20, 0) withAttributes:attrs];
// draw image
NSImage *myImage = [NSImage imageNamed:@"picture1.png"];
[myImage drawAtPoint:NSMakePoint(20, 40)
fromRect:NSZeroRect operation:NSCompositeCopy fraction:1.0];
Since the above uses the imageNamed convenience method of NSImage, the arg must be the name of an image file you've previously added to the main bundle (Project->Add to Project). The code for a gif would be exactly the same.
For more details see [Drawing Images into a View|https://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/Coc oaDrawingGuide/Images/Images.html#//apple_ref/doc/uid/TP40003290-CH208-BCIIBDAD] and [Simple Text Drawing|https://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/ CocoaDrawingGuide/Text/Text.html#//apple_ref/doc/uid/TP40003290-CH209-SW1] in the +Cocoa Drawing Guide+. Btw, the above is for OS X, since you asked about Cocoa. iPhone code is now called Cocoa Touch, so I hope I guessed the platform right. In case you really wanted iPhone, the code would be quite similar, but you'll need to substitute CGPointMake for NSMakePoint, UIColor for NSColor, UIImage for NSImage, and use a method like [drawAtPoint:forWidth:withFont:minFontSize:actualFontSize:lineBreakMode:baselin eAdjustment:|http://developer.apple.com/iphone/library/documentation/UIKit/Refer ence/NSStringUIKit_Additions/Reference/Reference.html#//appleref/doc/uid/TP40006893-CH3-SW14] for your text. You'll also only need one arg for the [drawAtPoint|http://developer.apple.com/iphone/library/documentation/UIKit/Refe rence/UIImageClass/Reference/Reference.html#//appleref/doc/uid/TP40006890-CH3-SW24] method of UIImage.
Hope that helps get you started!

Editing jpeg image

I need help editing the text in a jpeg image. The image is hard to read when I add it to my Indesign file.

Hello and welcome,
But I think you posted this in the wrong forum. This is one of the Captivate forums, and you are talking about something else.
JPEG is a compressed bitmap format, you will not be able to edit text in such a format. Do you know the origin? With Photoshop you could sharpen the image, but not sure at all that it will make the text readable, and you will never be able to edit the text. Only applications like Photoshop, when you add text in the application, allow that kind of functionality, but not an output, compressed format like JPEG.

HELP - CONVERTING A JPEG IMAGE INTO A LINE DRAWING

PLEEEASE HELP ME!!!
sorry to be thick - im only a beginner --- is there any way to covert a jpeg image into like a line drawing where there is a block colour background and solid lines that make up the picture like you sometimes get in brochures - somthing different to just the effects that are availible in the filter gallery...
thanks
LUK

As far as I recall there's no magic/easy "convert to vector drawing" functionality in Photoshop, though there are some things you can do to help smooth rough edges (e.g., Filter - Noise - Median). There are also some things you can do, if you want to get fancy, based on converting selections to paths, but that can get kind of involved and likely requires manual path editing afterward.
I have heard there are some pretty decent vector conversion functions in other Adobe apps... Adobe Illustrator, perhaps? Someone who uses Illustrator may want to chime in here; I don't have that package.

How can I quickly add text to a jpeg?

Hi folks,
I'd love to be able to just click on a jpeg and then add text to it. Preview Help says I can add text to an image by clicking Annotate and then Text, but I can't get anything to work. What am I doing wrong? Can anyone recommend a quick and easy way to add text to a jpeg?
TIA,
Renee

Select the menu option Tools -> Annotate -> Add Text. The cursor should change to a "cross-hair". Use that to draw a rectangle, then type.

Improve quality of JPEG images

Hi
I have an application which saves images in JPEG format after editing (well, many applications does that, but this is only a fraction of what this application does) :-)
I can't use any other formats due to size restrictions. The problem is Image Editing module of this application has operations like line drawing and text inserting. When I save the image, fine lines (especially texts) are getting blurred.
Is there any way I can increase the quality of JPEG files saved? I understand that JPEG is not meant for sharp lines and texts but with Photoshop, even fine lines and texts appear good when saved as a high quality JPEG file. Is there any such method in Java by which I can increase the quality of JPEG images?
Thanks in advance...

Is there any such method in Java by which I can increase the quality of JPEG images?I JPEG is a non-conservative compression format (you do not get back exactly what you put in, it has "acceptable degredaton"--I talked with the author before it became popular and he explained what JPEG was all about--high compresses resulting in a small size for internet communications over dialup.
In more recent times I've seen quality factors brought into play with JPEG, but as you have stated, even in Adobe Photoshop under the highest quality, you still have degradation. I've seen some hint and some state that you can get a lossless JPEG, but I've not encountered it yet.
In any case, if you do find a "lossless JPEG" the size of that file is going to be bigger than you are looking at now. You may consider other file formats--TIFF or there are even more recent files formats that have higher conservative compression algorithms.

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.

Is there a way to turn a text character into an image?

Is it possible to turn a text character into an image/shape...using Pages or any other iLife or iWorks app?
Reason being - I want to use a certain font and a character in it, but that particular font is not being recognized/shown properly by another computer. I want to make sure the text character shows up as I intend, and I figure the way to do that is by turning the text character into an image/shape (like a jpeg maybe? or a tiff or gif? I don't know too much about the difference between these last two). Then I can paste that image onto any background and have it still look like text laying on top of the background.
Hope that makes sense, and many thanks in advance for any insights!

Although it saves the text character as an image, it also saves the background (the white of the page) as part of that image. So when the character is pasted into a document whose background is anything other than white, it doesn't look like a simple text character anymore. It looks like a white box with a text character in it. You know what I mean?
I'm thinking I might need to use whole 'nother graphics program to do this whole deal...what do you think?
Rather than using Preview, create the new image from the clipboard in GraphicConverter & use the transparency wand to make the background transparent. Then use ⌘ E to select just the image & save, choosing to save just the selection.

Is there a way to overlay a soundcloud music player widget (flash or HTML5) ON TOP of a jpeg image?

I am designing my first webpage for a new site. It is very basic in function, where I am going to be embedding a bunch of soundcloud.com players of my music to my website. This part is fairly easy. I currently have Adobe Dreamweaver CS6.
Since I have ZERO webdesign experience, going the easy route is best. It was suggested to me by someone to create what I wanted my webpage to look like in photoshop (which I have lots of experience in). Essentially, I have a single image with lots of visual information on it, where I can then add "hotspots" if needed. So, I created my design, where there are specific areas ON TOP of the jpeg image where I want to overlay the soundcloud player. I am able to adjust the size, and format (HTML5 or Flash) of the player itself at soundcloud. I then have the proper code that needs to be put where I want it on top of my image.
Is there a simple piece of code, or a way in Dreamweaver to accomplish this in an easy way?
Thanks in advance!

Here is the widget code for HTML5 for the first one:

I need to edit text in a jpeg file. How do I do that?

Unfortunately you can't. A JPEG is a flat raster (pixel-based) image file which has no awareness of "text" inside it. You could try to erase the text and graphic under it and then recreate the text, but it's best to do so using a mastering format such as PSD (Photoshop) or PXM (Pixelmator), so that you can export as JPEG but keep your layered master for later editing.

Email showing up as jpeg image only? Links inoperative.

One of the people regularly sending me email recently changed their format. I'm now receiving only a jpeg image of their document. Instead of individual attachments, items now appear in the body of the email with links that do not work. The attachments should be PDF documents that should open in Preview or Acrobat Reader. I contacted the sender and was told they had no idea what's causing the problem. My correspondent said the mails work fine on his iMac. Any ideas?
Message was edited by: jvlahovich

My correspondent said the mails work fine on his iMac.
Of course they work fine on his Mac, because he's not sending email to himself. Your sender probably changed their sending format to Rich Text, as well as selecting Small from the Image Size popup menu in the bottom right corner of the compose window when they attached a PDF file; that would cause Mail to send only a .jpeg of the actual file instead of the actual file.
Ask them to send Plain Text only, and you should change your format for sending email to Plain Text. You should also ask them to just bundle all images they send into a .zip archive and attach it, and do not select anything other than Actual Size from the Image Size popup menu when attaching any documents or other types of files.

Adding Text to a Buffered Image

Hey
I am trying to add text to a bufferedimage image and have tried a couple of ways.
I cannot seem to get it to work propely though. Everytime i try, the text appears but the image appears inside the lettering of the text and not under it like i want it to.
Could someone please explain the best way of place text on TOP of an image as i am really stuck now :(
Thanks in advanced for any help

Basically paint your buffered image into a new BufferedImage and then paint in the new text on top.

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.
