How to vectorize a bitmap image

Are there any good java libraries that can vectorize a bitmap into splines/Bezier curves? etc
I already know autotrace, are there any other alternatives? it was written in C...
Thanks

Even if the photos in the sample images were vector artwork, there would be no advantage in it. They would still have to be reproduced using some kind of process screening, be it traditional halftone or stochastic.
Whomever is telling you that original artwork like those two samples has to be vector artwork doesn't know what he's talking about. Even if one did a photo-realistic rendering with a vector drawing tool, it would still have to be color-separated and screened for reproduction, just as if it were a raster image.
You may be dealing with a different printing vendor than the one that printed the samples (or a middle-person who doesn't really understand the requirements) if, in fact, those were printed on vinyl. Or, you may be involved with a simpler (lower priced) repro method option that is limited to line art.
People far too often specify that artwork "has to be vector" when in fact they really mean it has to be line art and/or spot color, as opposed to contone. It's quite conceivable that a vendor producing a durable product for use by children in a bath tub, and which therefore can't have flecks of ink coming off the plastic substrate, might have repro limitations which exclude contone screening. (The same principle commonly applies to many screen printing operations.) But that doesn't mean the original has to "be vector artwork"; it means it has to be line art that doesn't require screening (i.e.; not converted to toning dots).

How to convert color of bitmap image?

I am programming with Acrobat 7.
I'd like to change color of all object to CMYK color or gray.
In case of plain object like path or font,
I need to seek CMYK color from the object's RGB color.
and I change the property of the object color space and value with it.
but in case of bitmap image, i don't know how to at all.
it has numerous colors.
I hope your advice.

Thank you both of you.
by the way, Leonard, Could you tell me that APIs more detailly?
I have look into the document for long time. it is still hard to find proper API.
I have to say this again. I am trying to find APIs based on version 7.
I am using custom function ACEconvertColorProfile which is placed in snippetrunner. it consists of these APIS ACMakeColorTransform, ACApplyTransform, and so on.
but I can't find the way to convert bitmaps once and for all.
I hope you give more hint.
Thanks again.

How do I overlay n number of bitmap images using Java.

Hi All,
I have a task of creating a composite bitmap or a .gif image from "n" number of bitmap images , so that the resulting composite image will look like as if all those "n" images were placed side by side . How can I achieve this ? Can you point me to some place where I can understand the concepts behind this?

Create a new BufferedImage with the dimensions of all the images you want combined, then paint all the images into it through the Graphics object you can obtain from the BufferedImage. Then write out the image using the ImageIO class.

How Can I Clean up Imported Bitmap Images

Hi, I am using Flash 5. I have imported a sequence of .png images and they are looking pretty rough and bitmapped so I wanted to clean them up.
1. Do I have to select each frame after import and adjust the bitmap settings for each image or can I doo this somewhere so it affects al images?
2. I can’t find the settings for cleaning up the bitmap images. I thought they would be in the “Properties” panel?
3. Is there a way to fix the rasterization or clean up an imported .swf or is it better to clean up the sequence before saving as an .swf?

Ned Murphy wrote:
Ideally you should have images cleaned up/ properly sized / optimized before you import them into Flash. Once they are in Flash, one thing you can do that can help how the image displays, especially if you manipulate its size while in Flash, is to set the image to allow smoothing. This can be set using code or can be manually applied to the image in the library by right clicking it, selecting Properties, and checking the option to Allow Smoothing.
Thanks Ned,
Wow, exactly what I was looking for. Thanks. A huge improvement in the look of the gradients.

How to Convert Bitmap Images into WPF XAML files

http://stackoverflow.com/questions/15082716/can-we-convert-an-image-to-xaml-using-expression-blend
this is not a trivial task [and maybe beyond the scope of this forum]. If you had some vector image like svg images there might be a control out to use, but with raster images, I dont know of any control or code to use; I *think*, you will have to vectorize
the image content yourself, which isn't that easy...
So, is Background and Foreground easily distinguishable? Do shapes overlap? ...
If there are only some shapes in the image and BG and FG can be separated easily then you could "scan" the image by some chaincode like operation to get the contours/contour vectors and then decide what to do. If there are patterns in BG or FG
things will become more difficult, you then will have to perform more math-to-image operations and a vector-representation while reading/scanning the image might not be enough (keywords are computer vision, pattern recognition [with multi-linear-forms] etc).
Maybe an existing computer vision [-able] component loke opencv can help a lot...
Edit: I just did a google lookup and found eg this:

I havent read it so far, so I cannot say, if its what you need, but title and a quick view into looks promising/interesting.

How to transfer bitmap images?

Hello,
In the .NET client application that I am developing, I have to transfer bitmap images from the client to the SAP server. The size of each image file ranges from 1M to 10M. I am wondering if there is any standard RFC or BAPI that I can use to transfer chunks of binary data. Or, perhaps there is an RFC that can be used to transfer files.
Thank you in advance for your help.

How to load and save a Bitmap Image?

Hi, I have to load a directory of bitmap images, take the background(in this case: light green) and then swap those exact pixels with another image's corresponding pixels, and then save them in the same format(bitmap) in a different directory. Can anybody advise me on which libraries I need to use, and how I should approach this? I need help with every step so any help will be good. Thanks. Basically I need to do the following:
1. Load 2 directories of images(Lets say the images are corresponding like Image1A and Image1B)
2. Take Image1A's green pixels and swap them with the corresponding Image1B's pixels.
3. Save Image1A in a new Directory.
This will go on for however many images there are in those 2 directories. Can anybody advise me how to do this? I need critical help in all three stages. Thanks.

How do I embed bitmaps into a built (.exe) LabVIEW application?

I am trying to embedd bitmap images (icons) into the exe file of a built LabVIEW application. I tried it, and got them in a "data" folder. I want everything in the .exe file, you know, just like C/C++ or just about any other programming language.
If anyone has any tips, I would be grateful.
I know about embedding the images in the controls, but that is not my goal. I need images as files to be embedded, somehow, into the .exe. The reason is I am using the picture control to read the images, but they are static once they are read. If it is possible for the picture controls to somehow retrieve the images from some other source, that would work also.
Otherwise, if someone knows how to dynamicall
y embed bitmap or other images into buttons in an array, that would be useful as well.
Thanks

Actually, many C and C++ programs, like LV itself have folders of data
that aren't linked into their code. But, if that is what you are
looking for, one pretty easy way is to load the images into memory and
place them into a 2D array of data, a string etc. Make an array of
these and make the value default. At runtime, you can now skip the file
I/O, or you can write the data to a temporary on launch and read them
back whenever you like.

Bitmap image won't show after converting HTML file to pdf

I have a program which saves a technical report as a HTML file. I don't have another choice as to file type to save as. This program has a template which generates the report....and there are fields which are filled in...some text fields, and one is a company logo. Just to be clear the logo itself is not in the template, a holding place is there which points to the location of the logo on my drive. This is all set up by the program and can't be altered.
If I save the logo as a jpg, png or tiff file, the logo shows up in the final HTML report and if I use Adobe Professional (version 7.0 on Win XP) to create a pdf the image also shows up - a perfect replica of the report is created in pdf, making it convenient for printing and email.
If I save the logo as a bitmap file (which creates a higher resolution and sharper looking logo) the logo shows up in the initial HTML technical report, but when I convert this to pdf the file is not found, instead it shows as a small square red box with the error "Bad file image" or "unable to download image".
I can't understand why this would be the case as the logo is saved in the same location whether it is jpg, png, tiff or bmp. It just seems that the Adobe Pro doesn't know how to "find" the bitmap logo from the HTML template.
I did try converting the HTML document to Word but it threw the formatting out and when it was converted to pdf it cropped the page & I wasn't able to resolve this...maybe it can be done but it is a long way around in any case, particularly if steps then need to be taken to correct the formatting.
At the moment the document can be printed with success from the original format - then it's a matter of scanning the printed document in order to email. It can't be emailed directly because of the embedded information which is lost if then sent to the recipient's computer. However it would be nice if the doc could be converted to pdf which would then make it easier to transfer the file to a backup drive or for email. Any ideas? Thanks

Thanks for your response. Yes I did mean .bmp files.
The problem is not getting it to show in HTML - but Adobe then picking it up from there. I guess though if it is not a standard format for HTML then maybe Adobe has trouble recognising it if it is there. Also, it is possible for Adobe to convert .bmp files if they are inserted in the HTML file, but I have instead a template with the code for the location of the file rather than the graphic itself. I don't have this problem using the other file formats and getting them into pdf...it's just that the images aren't as sharp as the bmp. I have tried various formats and resolutions so if there isn't a way I can get the bmp from the HTML file into pdf I might just have to live with printing and scanning from the original. Thanks for your input, it confirms what I was thinking. I'll leave this unanswered for now in case someone else has further information.

Using a script to get the color of a colorized Black & White Bitmap image

I've been running into this wall for quite some time and would greatly appreciate any help that can given for it.
I have an Illustrator script that runs inside of a BridgeTalk session within an InDesign script. Yeah, it's complicated. The upshot is that the Illustrator part opens up an EPS file, looks through all objects on a certain layer in that file, and returns an array of the colors used in it. So, it looks at fill colors, stroke colors, gradient stops, etc. One of the biggest stumbling blocks (next to PlugIn Items, which I'll ask about in a separate post) is getting the color of raster images.
Most raster images, I realize, are going to be CMYK or RGB images, but our company mostly deals with either Grayscale images or Black & White Bitmaps that are embedded in the EPS file. Those two allow the ability to colorize them by simply selecting them and then choosing a color, such as a spot PANTONE color from one of their color books.
Now, I need the script to read the color that the raster image has been colorized with. This works okay for images that have a GrayScale color space, as the script just looks at Colorant[0] of that image. However, I run into a problem with Black & White Bitmap images. Here's a piece of code that I try to make work with an EPS file that has a raster image:
var document = app.activeDocument;
for (var i = 0; i < document.layers[0].pageItems.length; i++) {
          // Stepping through each item on the layer.
          var currentItem = document.layers[0].pageItems[i];
          $.writeln("Current item is " + currentItem.typename);
          $.writeln("Number of channels is " + currentItem.channels);
          $.writeln("Color Space is " + currentItem.imageColorSpace);
          $.writeln("Colorized Grayscale? " + currentItem.colorizedGrayscale);
          $.writeln("Number of Colorants: " + currentItem.colorants.length);
          for (var j = 0; j < currentItem.colorants.length; j++)
                    $.writeln("Colorant number " + j + " is " + currentItem.colorants[j]);
          $.writeln("Its parent is " + currentItem.parent);
          $.writeln("Parent's typename is " + currentItem.parent.typename);
This code runs successfully on an Illustrator file that has a Black & White Bitmap image on the top layer, but if you try and run it, you'll see the problem: Even if you've colorized your Bitmap image with a PANTONE spot color (and the script even returns "true" on the line "Colorized Grayscale?"), Colorant number 0 is "Gray". It should be the spot color assigned, not "Gray".
Can anyone please help me figure out how to get the script to recognize the actual colorant of a Black & White Bitmap image in Illustrator?

If you're a professional photographer with 50,000 pictures stored now and more coming all the time, you need to forget about using iPhoto and get yourself some professional-quality digital asset management software. iPhoto is not meant for people like you, and instead of providing a simple, elegant one-stop answer to all your needs, iPhoto is actually complicating your life.
You need an application that will:
- catalog ALL your images and keep track of where they are, no matter how many DVDs, folders, partitions or hard drives they're spread over;
- display thumbnails of ALL of them, even when the DVD that contains them is not present in any drive, so you can select all the ones you want for a project;
- find and copy (or export) the originals of all the files you've selected in the browser window, even if it means prompting you to insert the necessary DVDs for all of them.
I suggest Googling "digital asset management software Macintosh" and seeing what turns up. I used to use an old version of Extensis Portfolio, and even that would have been better for your purposes than iPhoto is.

Uneditable full-width bitmap images

Under what settings does Captivate record the state change of various UI elements, like the depression of buttons and the checking of check boxes, as additional narrow, full-width bitmap slices which are not editable or localizable?
For new recordings, it looks like creation of these slices can be avoided by deselecting Record keystrokes in the Recording > Settings category in Edit > Preferences or in Record/Create > New Project > Settings. Is this correct and a known issue?
Has anyone any insight on how to avoid these uneditable full-width bitmap images? The goal is to have a single background that can be localized so they are a major headache and I'd like to know how they can be avoided. Thanks.

I'm complelely baffled. The only bitmap you should have is the background. If you haven't solved your problem, send me your file or a representative slide or two so I can take a look. Sounds like gremlins in the Print Screen key.

How to attach jpeg photo images to AI artwork

How can I transform the perspective of a jpeg photo image and view the results in AI? Also, how can I attach this image over another AI vector artwork? Do I have to convert this rastor jpeg photo image to a vector image before I can do this?

How can I transform the perspective of a jpeg photo image and view the results in AI?
Use Object>Envelope Distort to transform a JPEG or any other image. Once the image is in a distortion mesh it can be distorted using the "Free Transform" tool or you can edit the mesh envelope by altering the mesh points directly, giving you endless control of the distortion.
Alternatively, you could use "Effect>3D>Rotate" to put a bitmap image into perspective.
Also, how can I attach this image over another AI vector artwork?
Not sure what you mean by "attach". You can group the transformed image with other objects. Or, if you find it helpful, you can expand the appearance to perminently distort the image.

Can someone please vectorize the following image :)

Hello. I was wondering if anyone could vectorize the following image and upload it as an .ai file? It's going to be a vital part of a birthday present for a friend, but I need to upscale it to a bigger proportion; however, the current image is a .png file and it becomes pixelated when I upscale it.
In addition to attaching the file, you can find the image here: http://i.imgur.com/23x0Z3D.png
It would be greatly appreciated, thank you.

Imagine if you will....
You walk into a bakery you've never been in before. You don't know anyone there, never seen the employees before, never had any conversations with them. You walk up to the counter and ask, "Hi, my name's Seriouslysjiasjdijas. You don't know me but I was wondering, would you mind making this cake for me as a favor?"
Or imagine you call Pizza Hut. You don't know anyone there, never had any real communication with them and you ask, "Hi, my name's Seriouslysjiasjdijas. You don't know me but I have a friend with a birthday coming up and I'm in need of a vital part of the present I'm giving. Would you mind delivering a pizza to my house? I sure would appreciate it. Thanks."
What do you think the responses would be?
Unlike many forums and web sites, this site may be a bit different because the bulk of the users here make a living doing this very sort of thing. Asking for a "favor" which amounts to free work and intellectual property infringement from a professional community which you've never been in before is simply flat out rude. That's right, you were the rude party here. FYI, many here make a living via intellectual property, they aren't of mind to start stealing from others just because you need a "favor." It's comical that my gentle nudging you to realize how rude you were being has, in turn, seemingly made you project the rudness you displayed as if it were my fault???
Where do you work? Can I walk into your place of business and expect free service as a favor? Why are you entitled to strangers doing you a favor? If I ask you to steal something for me, are you going to?
The work you posted is copyrighted. Meaning it's OWNED BY SOMEONE. You can't simply ask others to duplicate it trusting that your use is within warranted limits. No one here knows you. No one here has any clue what you'd use the artwork for. Anyone can post anything regarding their reasoning why they want someone to STEAL from others. That doesn't make it true. You could very well want the artwork to put on t-shirts and start selling them. How are we to know? Because you typed one sentence???
FYI, those sites you mention regarding t-shirt printing put the onus of infringement ON YOU. You are forced to agree to terms which contain specific passages where you agree you own the artwork and if you do not you are the liable party, not them. You clearly have never read what you are agreeing to there. While it may be true major corporations won't bother with you, you are liable. And any artist doing this "favor" of theft for you would also be liable unless you signed a similar agreement taking all legal responsibility for the unauthorized dulpication of copyrighted materials.
Ultimately, I posted one simple sentence and a question. The first politely explaining that what you were asking is improper here. The second a question to perhaps get you to reflect on what it was you were asking of strangers. Obviously, that failed. The fact that you've in turn decided the proper action is to begin insulting me for merely pointing out how rude you were being states a great deal. You've extrapolated a great deal from my two simple lines of text regarding who you think I am with no other information to base any of your opinions on, yet have completely missed the point that really.... you should be reflecting on what type of person would behave as you have behaved in this thread. You've now given the impression of a 6 year old throwing a tantrum because they were told "no." Good Job!
I'm not the party who was out of line here. If you think I am... then you should really look into your own actions. But hey, I realize as a user with a whopping 3 posts in this community you know EVERYTHING about everyone here and how things are done.
