• converting a png with an ICC profile?

  - by jedierikb

  I can convert a jpg from one ICC to another ICC. convert rgb_image.jpg -profile USCoat.icm cmyk_image.jpg Or I can convert a jpg with no ICC to another ICC. convert rgb_image.jpg +profile icm \ -profile sRGB.icc -profile USCoat.icm cmyk_image.jpg But how do I convert a png's pixels into the gamut described by an ICC profile? I understand I cannot embed the profile into the image file, but would at least like to convert the colors. When I reuse the above commands, the colors come out wrong... (different from the colors in the JPG when converted). This is the source image: http://alumni.media.mit.edu/~erikb/tmp/RED_JPG.jpg And here is what I am trying: convert RED_JPG.jpg +profile icm -profile sRGB_v4_ICC_preference.icc -profile USWebUncoated.icc CMYK_PNG.png and this is what I am getting: http://alumni.media.mit.edu/~erikb/tmp/CMYK_PNG.png I was hoping to get an image with the same colors as a JPEG run through the same command: convert RED_JPG.jpg +profile icm -profile sRGB_v4_ICC_preference.icc -profile USWebUncoated.icc CMYK_JPG.jpg resulting in: http://alumni.media.mit.edu/~erikb/tmp/CMYK_JPG.jpg *this image, CMYK_JPG.jpg, is what I am trying to reproduce pixel by pixel in a PNG file.* Any suggestions?

• Missing MB on a GPT partioned SSD

  - by pisswillis

  I recently installed Arch Linux on an Intel 40GB SSD. I used GPT for partioning (via GNU parted) and created the following partions: /dev/sda1 : 1 MB, no FS, flag=bios_grub /dev/sda2 : 30MB, /boot, ext2, flag=boot /dev/sda3 : 20GB, /home, ext4 /dev/sda4 : ~20GB, /, ext4 After struggling to install grub2 from the livecd environment (which I finally did via grub-install /dev/sda --root-directory=/mnt/ --no-floppy --force) I got a working system. However, when I was inspecting disk usage with df I noticed that my home partition had around 170MB of used space on it. This surprised me because the only things on /home were one users .bashrc, .bash_history, and .lesshst. du confirmed that there was only a few KB of space being used on /home. Why does df report approximately 170MB being used when du does not? Is this space "gone forever", or can I regain it by repartioning and/or reinstalling? When I installed grub2 it said something along the lines of "your embed area is too small", and that I could "use BLOCKLISTS, but BLOCKLISTS are UNRELIABLE". In the end the only way I could get a system booting from the SSD was to use blocklists via the grub-install --force flag. Is this related to the mysterious missing 170MB? Thanks

• Entity Framework with File-Based Database

  - by Dave Swersky

  I am in the process of developing a desktop application that needs a database. The application is currently targeted to SQL Express 2005 and works wonderfully. However, I'm not crazy about having this dependency on SQL Express and would prefer to use a small file-based database. My problem is that I am using Entity Framework. I have tried both SQL Compact and SQLite, and they both have bizarre problems with EF v1. I get errors creating the Model, invalid models when it does get created... it's a nightmare. I'm about ready to give up and write a data layer and repository in the good-old-school Connection/Command pattern. Not my favorite plan... Is there a lightweight, file-based database out there that plays well with EF? OR Is there a better ORM tool that I should use instead of EF with my lightweight DB?

• WPF Animate a Matrix using interpolation

  - by Mark

  I'm having a issue with my application that is using touch gestures to scale, translate and rotate my scene. I was using a TransformGroup which contained TranslateTransform, ScaleTransform and a RotateTransform but I could not get the movement correct, it always jumps and skips, so I moved to a MaxtrixTransform which I was able to use much easier to get my scene to be zoomable, rotatable and panable nicely. However, what I later found out was that you cannot animate smoothly (using interpolation) the values of a Matrix, for what reason I have no idea, but its part of the MSDN doco and the properties of the Matrix are not dependency properties anyways... Has anyone had any luck animating a matrix to make it smooth? The only idea(s) I have had is to animate a few different, custom DP which all have callbacks that I update the matrix from OR To convert the matrix to a set of Transform objects that I then animate and then afterwords convert back. Is there a smarter way to do this?

• Generate all project dependencies in a single file using gcc -MM flag

  - by Jabez

  Hi all, I want to generate a single dependency file which consists of all the dependencies of source files using gcc -M flags through Makefile. I googled for this solution but, all the solutions mentioned are for generating multiple deps files for multiple objects. DEPS = make.dep $(OBJS): $(SOURCES) @$(CC) -MM $(SOURCEs) > $(DEPS) @mv -f $(DEPS) $(DEPS).tmp @sed -e 's|.$@:|$@:|' < $(DEPS).tmp > $(DEPS) @sed -e 's/.*://' -e 's/\\$$//' < $(DEPS).tmp | fmt -1 | \ sed -e 's/^ *//' -e 's/$$/:/' >> $(DEPS) @rm -f $(DEPS).tmp But it is not working properly. Please tell me where i'm making the mistake.

• Is it OK to reference 'this' when initializing a field?

  - by parxier

  Is it OK to reference this when initializing a field? public class MainClass { private SomeFieldClass field = new SomeFieldClass(this); public MainClass() {} } Or is it better to do that in constructor? public class MainClass { private SomeFieldClass field; public MainClass() { this.field = new SomeFieldClass(this); } } What is the best practice? I believe first option is better for unit testing and dependency injection. Are there any problems with it?

• Win32 api call via C# fails!

  - by user434186

  Hi. I have a C++ function exported as api like this: #define WIN322_API __declspec(dllexport) WIN322_API char* Test(LPSTR str); WIN322_API char* Test(LPSTR str) { return "hello"; } the function is exported as API correctly by the .DEF file, cause i can see it in Dependency Walker tool. Now i have a C# tester program: [DllImport("c:\\win322.dll")] public static extern string Test([MarshalAs(UnmanagedType.LPStr)] String str); private void Form1_Load(object sender, EventArgs e) { string _str = "0221"; Test(_str); // runtime error here! } on calling the Test() method i get the error: "A call to PInvoke function 'MyClient!MyClient.Form1::Test' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature." i tried many other data types and marshalings, but got nothing! plz help me!

• Program crashes in debugger before anything happens

  - by Tim

  I'm building an application for Windows XP using the MinGW tool chain and it sometimes crashes unexpectedly. So, I'm trying to use a debugger (Gdb) but the program exits with code 03 before anything happens. In fact, all I see from GDB is: [New thread 3184.0x7b8][New thread 3184.0xef8] Program exited with code 03. My suspicion is that there is some failed dynamic linking of a dependency (which are Qt, VTK, and ITK, all built with MinGW). However, this does not happen when I just run the program normally. Or if it happens, it appears to be intermittent and well after the program is launched and running. NOTE: I'm also using Cmake for cross compiling. What should I do? What can I try?

• How to include NetBeans Platform Source code into module dependencies

  - by Ben Hammond

  I am debugging a NetBeans Platform application. I have downloaded the NetBeans Platform source code .zip file. I would really really like to attach the source code to the debugger so that I can seamlessly jump to internal NB source code. Normally I would edit the Library configuration to tell NB where to find the source code, and it would just work. However this is not possible for NetBeans Modules; when I look at the Utilities API module dependency it does not look like a normal NB library and there is nowhere to add in the source code. I suspect that if I were to rebuild my project using Maven this would work automatically. But thats a terrible reason to switch to maven. How can I get the NB Platform Source code included into my Module Dependencies ?

• Java paint speed relative to color model

  - by Jon

  I have a BufferedImage with an IndexColorModel. I need to paint that image onto the screen, but I've noticed that this is slow when using an IndexColorModel. However, if I run the BufferedImage through an identity affine transform it creates an image with a DirectColorModel and the painting is significantly faster. Here's the code I'm using AffineTransformOp identityOp = new AffineTransformOp(new AffineTransform(), AffineTransformOp.TYPE_BILINEAR); displayImage = identityOp.filter(displayImage, null); I have three questions 1. Why is painting the slower on an IndexColorModel? 2. Is there any way to speed up the painting of an IndexColorModel? 3. If the answer to 2. is no, is this the most efficient way to convert from an IndexColorModel to a DirectColorModel? I've noticed that this conversion is dependent on the size of the image, and I'd like to remove that dependency. Thanks for the help

• WPF - databinding ObservableCollection CollectionChanged event?

  - by e0eight

  Hi, I have an observable collection implemented in my user control which indicates states of a device. Based on the collection change, the user control is to trigger animations(subscribe to collectionchanged event). The observable collection is implemented as a dependency property. In the application, I data bind the device states to the user control observableCollection using one-way databinding. When a new state is added in the application, I can see the ObservableCollection in the user control is updated. However, the CollectionChanged event never got fired, so no animations. Does anyone has an idea why this is so? Thank you in advance.

• Compilation error on a user control

  - by MikeP

  I'm stumped! We have a user control for managing account information. We use this particular control on two pages. On one page, everything works perfectly and meets our expectation. On the second page however we receive compilation errors stating that: "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\lrpcentral\0e987bea\6719c8b6\App_Web_PageThatFails.aspx.f3d462c1.oi52bvii.0.cs(172): error CS0433: The type 'xxxx_ascx' exists in both 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\APPLICATIONNAME\0e987bea\6719c8b6\App_Web_xxxx.ascx.cdcab7d2.xbnvt2za.dll' and 'c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\APPLICATIONNAME\0e987bea\6719c8b6\App_Web_eix7xllr.dll' My problem is similar to Cyril's but the "delete everything from Temp" is not an option for me, and Cyril's solution does not apply since the only variable we have is contained in the designer file, which is not deployed to our production environment (we pre-compile). After reading David's answer (here) I examined my directories for circular dependency and was unable to find any. Structure: Top Level Page that works Control Directory A Page that causes the error

• ActiveRecord Save Dependent Model

  - by Dmitriy Likhten

  I am trying to save a model with it's dependency models being saved. Model1 has_many :model2, :autosave => true Model2 belongs_to :model1 has_many :model3, :autosave => true Model3 belongs_to :model2 I want to save Model1, and have Model2 and 3 save as well. I tried this without and with the autosave feature. What winds up happening is Model1 is saved, Model2 is saved, Model3 is untouched. Is there a way to tell ActiveRecord that for this save I want to save the model and all child models all at once? As a side note, all 3 are just created and are not in the database. I cannot do .create on the models because I cannot save them until all validation passes and all business logic succeeds (has to be a transaction).

• How to highlight matching sub-strings inside a ListBox?

  - by Kishore Kumar

  I have one TextBox and one listbox for searching a collection of data. While searching a text inside a Listbox if that matching string is found anywhere in the list it should show in Green color with Bold. eg. I have string collection like "Dependency Property, Custom Property, Normal Property". If I type in the Search Text box "prop" all the Three with "prop" (only the word Prop) should be in Bold and its color should be in green. Any idea how it can be done?. Data inside listbox is represented using DataTemplate.

• installing windows service with SC.exe or InstallUtil.exe - there is difference but which?

  - by LosManos

  hejdig. SC.exe and InstallUtil both install/uninstall windows services. But they don't seem to work the same way. What is the difference? For instance InstallUtil fails (some file or dependency not found error) while Sc create happily installs the service. Too add to the strangeness; the service doesn't show up if I run net start in the console. But it does show up in the services GUI. Variants of this happen when I try to uninstall. I have written the service myself and earlier versions work. Dotnet3.5. /OF

• Silverlight 4 Assembly Sharing Problem

  - by jeffn825

  I have a WPF .NET 4.0 class library referencing a Silverlight 4 class library. The SL library compiles fine but when I compile the WPF class library, I get: Error 2 Unknown build error, 'Cannot resolve dependency to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.' MyProj.Presentation.Wpf I figure the problem must be similar to the one mentioned here: http://markti.spaces.live.com/blog/cns!D92CF278F0F91957!273.entry but my WPF library doesn't contain any XAML that references a user control from my SL library. In fact, my SL library doesn't have any XAML in it at all. It does, however, have several shared DependencyObjects, such as an EventCommander (binding UI element events to Commands), and some DataTemplate helpers. Is there any way I can narrow down the problem here? And has anyone found a way of effectively referencing UI elements in a SL4 project from .NET 4.0? Thanks.

• Are the contents of a fragment visible outside the host plugin?

  - by Mike Daniels

  I have never worked with plug-in fragments before. I thought that by creating a new class within a fragment and exporting the package that contains it in the fragment's manifest, I'd be able to access that class from another plug-in that already has a dependency on the host plug-in. However, I cannot seem to make this work. Are the contents of a fragment ever visible to any plug-in besides the host plug-in? If so, is there something special I have to do to allow this?

  Goal: Install Hunchentoot and be able to run Hunchentoot as a background thread. This is what I do: Install Common Lisp. Install Quicklisp. (ql:quickload "hunchentoot") (hunchentoot:start (make-instance 'hunchentoot:acceptor :port 4242)) The last command is supposed to start Hunchentoot, then return to the interpreter for further Common Lisp forms. For CLISP, SBCL, ABCL, ECL, and CCL, I get one of two results: Hunchentoot's dependency Bordeaux Threads fails to install. hunchentoot:start hangs. The web page never loads, and never 404s.

• To keep my own versioned app or not.

  - by Esteban Feldman

  Hi all. I need some opinions here. I'm working on a Django project using buildout to get the dependencies, etc... I use mercurial as DVCS. Now... I need to customize one of the dependencies, so I can do one of the following: (* The changes may not be useful for everyone else.) 1- Do a fork of the project in (github, bitbucket, etc...) maintain my version, and get the dependency with (mercurial or git) recipe. 2- Clone the project, put it in the PYTHONPATH, erase DVCS dirs and add it to my projects version. So every change will be private. Here I need to erase all the info from their DVCS or something. Any other you can think of. I'm missing something? I'm too off? Thanks!
