  • How to convert CMYK to RGB programmatically in indesign.

    - by BBDeveloper
    Hi, I have a CMYK colorspace in indesign, i want to convert that as RGB color space, I got some codes, but I am getting incorrect data. Some of the codes which I tried are given below double cyan = 35.0; double magenta = 29.0; double yellow = 0.0; double black = 16.0; cyan = Math.min(255, cyan + black); //black is from K magenta = Math.min(255, magenta + black); yellow = Math.min(255, yellow + black); l_res[0] = 255 - cyan; l_res[1] = 255 - magenta; l_res[2] = 255 - yellow; @Override public float[] toRGB(float[] p_colorvalue) { float[] l_res = {0,0,0}; if (p_colorvalue.length >= 4) { float l_black = (float)1.0 - p_colorvalue[3]; l_res[0] = l_black * ((float)1.0 - p_colorvalue[0]); l_res[1] = l_black * ((float)1.0 - p_colorvalue[1]); l_res[2] = l_black * ((float)1.0 - p_colorvalue[2]); } return (l_res); } The values are C=35, M = 29, Y = 0, K = 16 in CMYK color space and the correct RGB values are R = 142, G = 148, B = 186. In adobe indesign, using swatches we can change the mode to CMYK or to RGB. But I want to do that programmatically, Can I get any algorithm to convert CMYK to RGB which will give the correct RGB values. And one more question, if the alpha value for RGB is 1 then what will be the alpha value for CMYK? Can anyone help me to solve these issues... Thanks in advance.

  • Portlet container like pluto or jetspeed on google app engine?

    - by Patrick Cornelissen
    I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible. Has anyone tried to run jetspeed or an application that uses pluto internally on the google app engine? Based on my current knowledge of portlets and the google app engine I'm anticipating these problems: A war file with portlets is from the deployment standpoint more or less a complete webapp (yes, I know that it doesn't really work without a portal server). The war file may contain it's own web.xml etc. This makes deployment on the app engine rather difficult, because the apps are not visible to each other, so all portlet containing archives need to be included in the war file of the deployed "app engine based portal server". The "portlets" are (at least in liferay) started as permanent servlet processes, based on their portlet.xmls and web.xmls which is located in the same spot for every portlet archive that is loaded. I think this may be problematic in the app engine, because everything is in one big "web app", so it may be tricky to access the portlet.xmls from each archive. This prevents a 100% compatibility in my opinion. Is here anyone who has any experience with the combination of portlets and the app engine? Do you think it's feasible to modify jetspeed, pluto or any other portlet container to be able to run it on the app engine?

  • SAXException: Unexpected end of file after null

    - by itsadok
    I'm getting the error in the title occasionally from a process the parses lots of XML files. The files themselves seem OK, and running the process again on the same files that generated the error works just fine. The exception occurs on a call to XMLReader.parse(InputStream is) Could this be a bug in the parser (I use piccolo)? Or is it something about how I open the file stream? No multithreading is involved. Piccolo seemed like a good idea at the time, but I don't really have a good excuse for using it. I will to try to switch to the default SAX parser and see if that helps. Update: It didn't help, and I found that Piccolo is considerably faster for some of the workloads, so I went back.

  • Alternative Control Structures

    - by Brock Woolf
    I've been wondering about alternative ways to write control structures. One that you learn early on for if statements is a replacement for this: if ( x ) { // true } else { // false } with this (sometimes this is more readable compared to lots of brackets): x ? true : false It got me thinking. Can we replace anything else incase it's more readable. We of course replace if statements like this: if (a < b) { return true; } else { return false; } with things like this: return a < b; We can save a long if with something like this (pretty much same as the one above): bool xCollisionTrue = (object.xPos < aabb.maxX && object.xPos > aabb.minX); So those are the ones I can think of off the top of my head for the if statement and doing comparisons. So I'm wondering what about looping constructs, for, while, etc. Maybe the code obfuscators might have some ideas.

  • Ibatis startBatch() only works with SqlMapClient's own start and commit transactions, not with Sprin

    - by Brian
    Hi, I'm finding that even though I have code wrapped by Spring transactions, and it commits/rolls back when I would expect, in order to make use of JDBC batching when using Ibatis and Spring I need to use explicit SqlMapClient transaction methods. I.e. this does batching as I'd expect: dao.getSqlMapClient().startTransaction(); dao.getSqlMapClient().startBatch(); int i = 0; for (MyObject obj : allObjects) { dao.storeChange(obj); i++; if (i % DB_BATCH_SIZE == 0) { dao.getSqlMapClient().executeBatch(); dao.getSqlMapClient().startBatch(); } } dao.getSqlMapClient().executeBatch(); dao.getSqlMapClient().commitTransaction(); but if I don't have the opening and closing transaction statements, and rely on Spring to manage things (which is what I want to do!), batching just doesn't happen. Given that Spring does otherwise seem to be handling its side of the bargain regarding transaction management, can anyone advise on any known issues here? (Database is MySQL; I'm aware of the issues regarding its JDBC pseudo-batch approach with INSERT statement rewriting, that's definitely not an issue here)

  • ListAdapter to modify the datasource (which is an arraylist)

    - by dusker
    Hi Everyone, here's a problem that i've run into lately: I have a listview with a custom adapter class, the adapter takes in a listview and populates the listview with elements from it. Now, i'd like to have a button on each row of a listview to remove the item from it. How should i approach this problem? Is there a way to remotely trigger a method in the activity class and call notifydatachanged() method on the adapter to refresh the listview? thanks in advance for your help and some code snippets if possible best regards peter

  • common problem with Hibernate/NHibernate and child IDs

    - by tyndall
    I'm asking both Hibernate and NHibernate groups because I'm thinking this may be a common issue seen on both. What does it usually mean when you call a saveOrUpdate on a child object and... 1) If it is an insert everything works fine. 2) If it is an update its wiping out the parent ID in the database.

  • IVR-style dialog system

    - by unbeli
    I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

  • How to get local ActiveMQ broker to "mirror" a queue on a remote ActiveMQ broker?

    - by T.K.
    I have a local ActiveMQ broker which is on an unreliable internet connection, and also a remote ActiveMQ broker in a reliable datacenter. I have already sorted out a "store and forward" setup so that outgoing messages are sent to the remote broker when the Internet connection is available. That alone works great, but when messages are outbound. However, now I have to do the reverse. Here is the scenario: A new message appears in the remote ActiveMQ broker. The message is put into a specific queue. In a few minutes, the Internet connection becomes available to the local ActiveMQ broker. The local broker should then be able to pull the message from the remote broker, and place it in its own local queue. Local consumers will then be able to see the message. So in essence, I need the local broker to become a subscribed consumer to the remote queue. I have looked through the ActiveMQ documentations but I can't find anything yet about how to do this in the .xml configuration file. Is this what I should be looking for? See: "ActiveMQ: JMS to JMS Bridge". Any advice and tips would be highly appreciated.

  • Infinispan equivalent to ehcache's copyOnRead and copyOnWrite

    - by waxwing
    Hi, I am planning to implement a cache solution into an existing web app. Nothing complicated: basically a concurrent map that supports overflowing to disk and automatic eviction. Clustering the cache could be requirement in the future, but not now. I like ehcache's copyOnRead and copyOnWrite features, because it means that I don't have to manually clone things before modifying something I take out of the cache. Now I have started to look at Infinispan, but I have not found anything equivalent there. Does it exist? I.e., the following unit tests should pass: @Test public void testCopyOnWrite() { Date date = new Date(0); cache.put(0, date); date.setTime(1000); date = cache.get(0); assertEquals(0, date.getTime()); } @Test public void testCopyOnRead() { Date date = new Date(0); cache.put(0, date); assertNotSame(cache.get(0), cache.get(0)); }

  • How to Use Grizzly Embedded Server for Mule as Well as Jersey

    - by Tim
    I'm currently using JerseyTest w/ Grizzly embedded server to test some code. I do some very simple configuration to point it to the proper resources: Map<String, String> initParams = new HashMap<String, String>(); initParams.put("com.sun.jersey.config.property.packages", "com.sample.service"); ApplicationDescriptor appDescriptor = new ApplicationDescriptor(); appDescriptor.setServletInitParams(initParams); super.setupTestEnvironment(appDescriptor); This works fine and the Jersey components are available and working as expected. I'm now trying to add some Mule functionality to some of these Jersey calls, but Mule is not being properly initialized/configured by Grizzly. Has anyone gotten this kind of setup running? What additional configuration do I need to do with JerseyTest/GrizzlyWebServer to get it to initialize Mule properly?

  • Wicket: Relative to absolute URL or get base URL

    - by Gilean
    If I have a relative path to a static asset (flash/blah.swf), what is the best way to convert this to an absolute URL (http://localhost/app/flash/blah.swf)? Or what is the best way to get the base URL of the Wicket application? I've tried using RequestUtils.toAbsolutePath but it doesn't seem to work reliably and is frequently throwing exceptions.

  • algorithm for image comparison

    - by Rajnikant
    Please consider following use case, I have one bigger image, lets called is master image. Now from some where else, I am getting one small image. I want to check whether this small image is subset of master image or not. important points are, smaller image might have different file format, smaller image might captured from comparatively different view. smaller image may have different light intensity. At this stage of algorithm/computation advancement, which level of accuracy I could expect? Any algorithm/open source implementation that would have such implementation? Thanks, Rajnikant

  • Should I use a collection here?

    - by Eva
    So I have code set up like this: public interface IInterface { public void setField(Object field); } public abstract class AbstractClass extends JPanel implements IInterface { private Object field_; public void setField(Object field) { field_ = field; } } public class ClassA extends AbstractClass { public ClassA() { // unique ClassA constructor stuff } public Dimension getPreferredSize() { return new Dimension(1, 1); } } public class ClassB extends AbstractClass { public ClassB() { // unique ClassB constructor stuff } public Dimension getPreferredSize() { return new Dimension(42, 42); } } public class ConsumerA { public ConsumerA(Collection<AbstractClass> collection) { for (AbstractClass abstractClass : collection) { abstractClass.setField(this); abstractClass.repaint(); } } } All hunky-dory so far, until public class ConsumerB { // Option 1 public ConsumerB(ClassA a, ClassB b) { methodThatOnlyTakesA(a); methodThatOnlyTakesB(b); } // Option 2 public ConsumerB(Collection<AbstractClass> collection) { for (IInterface i : collection) { if (i instanceof ClassA) { methodThatOnlyTakesA((ClassA) i); else if (i instanceof ClassB) { methodThatOnlyTakesB((ClassB) i); } } } } public class UsingOption1 { public static void main(String[] args) { ClassA a = new ClassA(); ClassB b = new ClassB(); Collection<AbstractClass> collection = Arrays.asList(a, b); ConsumerA consumerA = new ConsumerA(collection); ConsumerB consumerB = new ConsumerB(a, b); } } public class UsingOption2 { public static void main(String[] args) { Collection<AbstractClass> collection = Arrays.asList(new ClassA(), new ClassB()); ConsumerA = new ConsumerA(collection); ConsumerB = new ConsumerB(collection); } } With a lot more classes extending AbstractClass, both options get unwieldly. Option1 would make the constructor of ConsumerB really long. Also UsingOption1 would get long too. Option2 would have way more if statements than I feel comfortable with. Is there a viable Option3? If it helps, ClassA and ClassB have all the same methods, they're just implemented differently. Thanks for slogging through my code!

  • Generic JMS Client

    - by Damo
    Does anyone know if it is feasible to write a Generic JMS client - ie. one that works with JMS from different providers (eg. Sonic, IBM SIB, Jboss etc)? Every time I've written JMS client code it is always very implementation specific with dependent JARs and Context classes. Thanks.

  • Sun permgen & JRockit garbage collection

    - by Striker
    In the Sun JVM, classes that are loaded by the class loader are put in permgen space and never gc'd. (Unless the class loader goes out of scope) It's my understanding that JRockit puts that same data on the heap instead. Is that data then subject to garbage collection? Thanks.

  • JEditorPanes, Preferred Size, and printing HTML

    - by Ryan Elkins
    I'm trying to print some HTML directly, without displaying anything to the user. It works currently (somewhat) using a custom JEditorPane that implements Printable. The problem I'm having is that it always wants to use a preferred size of 582px x 560px. If I manually change the size using something like setSize(x,y) it will change the size of the pane, put the content renders at preferred size, not actual size (so it's still 582x560). I can scale it up to fit the page, but it's basically just an enlarged version where the images are all pixelated and the layout is wrong (based on the smaller window size). Inside the print method of my Printable JEditorPane I used this to try and get the size: javax.swing.JWindow wnd = new javax.swing.JWindow(); wnd.setContentPane(this); wnd.setSize(1024,1584); wnd.pack(); Dimension d = wnd.getPreferredSize(); With or without that setSize and/or pack methods on the JWindow the preferred size always comes back as 582x560. I do have control over the html that I'm trying to print but I'd rather not have to rewrite all of that to scale it down so it will print correctly at full size (when scaled up).
