I have tried tess4j as a standalone java program and it worked properly giving the text output. Now i am trying to create a spring mvc web project adding the dependencies for tess4j in pom and i have added the tess4j source inside my project. File imageFile = new File("D:/Data/jars/tess/eurotext.tif"); Tesseract instance = Tesseract.getInstance(); // JNA Interface Mapping // Tesseract1 instance = new Tesseract1(); // JNA Direct Mapping try { result = instance.doOCR(imageFile); System.out.println(result); } catch (TesseractException e) { System.err.println(e.getMessage()); } The above code

I recently started my first program with GeoTools in which i was also using JAI- Java Advanced Imaging 1_1_2_01 with JDK 1_7. It worked fine until I added GeoTiff Jars . I found following error Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class javax.media.jai.JAI at org.geotools.gce.geotiff.GeoTiffReader.read(GeoTiffReader.java:607) at com.rgb.PixelExtractor.extract(PixelExtractor.java:55) at com.rgb.RGBSpliter.main(RGBSpliter.java:136) The Code is as below public void extract(File f, String name, String date) throws Exception { ParameterValue<OverviewPolicy

For the needs of my program I have created a facility to distort an image and place it on a map (my program is a map based program). I wrote my own mechanism for placing and distorting the image using three points that are placed on the image, three points that are placed on the map and then what I simply do it create an AffineTransform that transforms the first triangle to the second, in effect placing the image exactly where I want it and transformed to fit what the user wanted. The problem is that with AffineTransforms you can only perform the most basic of transformations. You can

First, I would like to say I'm not an image processing specialist. I would like to convert image colorspace from one to another, and change icc color profile at the same time. I managed to do it using JMagick (the ImageMagick Java port), but no way in pure Java (even using JAI). Use ColorConvertOp , this will do the color space conversion. You have several options to set a icc color profile. Either you use a predefined profile by using getInstance with the correct color space constant or you can specify a file, which contains a profile. Here is an example: ICC_Profile ip = ICC_Profile

first I'd like to explain the situation/requirements that lead to the question: In our web application we can't support CMYK images (JPEG) since IE 8 and below can't display them. Thus we need to detect when someone wants to upload such an image and deny it. Unfortunately, Java's ImageIO won't read those images or would not enable me to get the detected color space. From debugging it seems like JPEGImageReader internally gets the color space code 11 (which would mean JCS_YCCK ) but I can't safely access that information. When querying the reader for the image types I get nothing for CMYK, so I
