For a web project I need the possibility to generate jpg and animated gif images very fast. As server platform I will use Linux and the NekoVM (behind a apache via mod_tora). As there is no library for image generation for haXe and neko I am about to write a own one. Neko itself is written in c, and you can simply extend the VM writing ...

ImageIcon imageIcon = new ImageIcon(imageFile.getAbsolutePath()); ImageIcon support the typical png,gif,jpg images. In the project i am working, i can not open a bmp file and store the same file as a jpg, bec...
We have many Crystal Reports (8,11) files with picture fields. The image data is comming from BLOB fields in a temporary database. The problem: The Crystal Reports designer is showing the image, which was in the database at the time the field was inserted and it seems the picture data is saved within the .rpt file. This leads to huge .r...
I'm looking for some kind of formula or algorithm to determine the brightness of a color given the RGB values. I know it can't be as simple as adding the RGB values together and having higher sums be brighter, but I'm kind of at a loss as to where to start. ...
I need to create fingerprints of many images (about 100.000 existing, 1000 new per day, RGB, JPEG, max size 800x800) to compare every image to every other image very fast. I can't use binary compare methods because also images which are nearly similar should be recognized. Best would be an existing library, but also some hints to existi...
To clarify the title question, I have code such as: <img src='gallery/main.php?g2_view=core.DownloadItem&g2_itemId=8161&g2_serialNumber=2&g2_GALLERYSID=5b24df90ee45f0e01795a3c01a1d634b'> with the file actually residing in the file system under my webroot. Is there any way in PHP to retrieve the images real path being served such as: ...
Hey, I'm trying to convert an Image object to a byte array then back to an Image (so that I can store the image in a blob object in an Apache Derby Database). I can convert an Image to a byte array (code below) but I cann't convert the bytes back to an image. As a further complication I'm using J2ME, so I can't use javax.image.*. Can y...
Example: <div id="sampleimage"> ***Stream or Serialize JPEG Image from Server Here w/o Sending another Request*** </div> So basically, send everything in a single response. ...
I have a method that gets called at the start of my program, and it works fine when I run the jar, but when I run the jnlp file it crashes. public void newImg(String i) { try { File file = new File(i); img = ImageIO.read(file); } } img is a bufferedImage, by the way. ...
I have a script that will output a jpg, gif or png image. It uses the appropriate content-type according to the extension of the file (which in this case will be the right one always). The problem is, I have a small number of files which will cause a 500 internal server error when I try to access them this way. However they work if I tr...
Okay, now I've been using drawImage in java for a while, and this has never happened before. Why can't it find "drawImage(java.awt.image.BufferedImage,<nulltype>,int,int)" in my code? import java.awt.*; import javax.swing.*; import javax.swing.JPanel; import java.awt.event.*; import java.awt.image.*; import java.io.*; import java....
Okay, so I've been trying to load a BufferedImage using this code: URL url = this.getClass().getResource("test.png"); BufferedImage img = (BufferedImage) Toolkit.getDefaultToolkit().getImage(url); This gives me a type cast error when I run it though, so how do I properly load a BufferedImage? ...
Hi, i would like to extract information is there a human hand on some photo taken from local webcam. I get how to extract light information, find brightest points or few of them, but how to recognize shape on some image? I have started C# project, and I'm using AForge library to apply some filters to captured images, but I'm pretty stu...
I need to make a basic image viewer. The main concern is how to implement (in terms of gui components and image manipulation) such features as: zoom in-out, scroll and 'hand tool'. There seems to be several options for achieving this goal, differing mainly in degree of putting responsibilities on the graphical interface framework as opp...
On the iPhone, if you touch and hold your finger on an icon, it starts vibrating, then you can drag them around while the other icons move aside and rearrange dynamically. I'm trying to figure out how to do this inside an application with a grid of images or buttons. I don't need them to vibrate, but I do want the UI to allow the user ...
Is there a simple way to display a color bitmap in grayscale with just HTML/CSS? It doesn't need to be IE-compatible (and I imagine it won't be) -- if it works in FF3 and/or Sf3, that's good enough for me. I know I can do it with both SVG and Canvas, but that seems like a lot of work right now. Is there a truly lazy person's way to do...
I am trying to create a personal home page for myself to learn more about web design (JavaScript, using Photo Shop, etc). I plan on having a graphical menu on the left, a banner across the top and also a "Photos" section where I can display photos of various pictures I have taken. However, when I look at other sites that do anything sim...
I'm hoping someone can help me with a question I have about images and GridView controls in ASP.Net 2.0. I'm trying to put together a photo album application as a learning exercise which uses a GridView control with two columns. Column one will display the image (using an image column type) based on a URL held in the database I am using...
I have a sql server database that returns byte for the image. If I use the tableadapter wizard and set it to my stored procedure and preview data, it pulls back an image. It automatically turns it into an image in the preview data. I don't see it as a string of Ints or anything. How can I display it on my asp.net webpage with a gridv...
Do you guys know of any algorithms that can be used to compute difference between images? Take this webpage for example http://tineye.com/ You give it a link or upload an image and it finds similiar images. I doubt that it compares the image in question against all of them (or maybe it does). By compute I mean like what the Levenshtein...
