  • java regex for alpha and spaces is including [ ] \

    - by JayAvon
    This is my regex for my JTextField to not be longer than x characters and to not include anything other than letters or spaces. For some reason it is allowing [ ] and \ characters. This is driving me crazy. Is my regex wrong?? package com.jayavon.game.helper; import java.awt.Toolkit; import javax.swing.text.AttributeSet; import javax.swing.text.BadLocationException; import javax.swing.text.PlainDocument; public class CharacterNameCreationDocument extends PlainDocument { private static final long serialVersionUID = 1L; private int limit; public CharacterNameCreationDocument(int limit) { super(); this.limit = limit; } public void insertString(int offset, String str, AttributeSet attr) throws BadLocationException { if (str == null || (getLength() + str.length()) > limit || !str.matches("[a-zA-z\\s]*")){ Toolkit.getDefaultToolkit().beep(); return; } else { super.insertString(offset, str, attr); } } }

  • How to find missing alpha values in sets of data within same table in SQL

    - by Jeff
    I have a table of many values where one column has the WO Number, and another column has the Resource ID. I need to be able to find all the WO numbers that do not have a resource value of "RW". Here is an example of the typical information. I need to be able to know that work order 5678 does not have an "RW" Resource ID. WO Number - Resource ID 1234 - IN 1234 - WE 1234 - AS 1234 - RW 5678 - PR 5678 - WE 5678 - IN 5678 - AS

  • Creating a mask from a graphics context

    - by Magic Bullet Dave
    I want to be able to create a greyscale image with no alpha from a png in the app bundle. This works, and I get an image created: // Create graphics context the size of the overlapping rectangle UIGraphicsBeginImageContext(rectangleOfOverlap.size); CGContextRef ctx = UIGraphicsGetCurrentContext(); // More stuff CGContextDrawImage(ctx, drawRect2, [UIImage imageNamed:@"Image 01.png"].CGImage); // Create the new UIImage from the context UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); However the resulting image is 32 bits per pixel and has an alpha channel, so when I use CGCreateImageWithMask it doesn't work. I've tried creating a bitmap context thus: CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceGray(); CGContextRef ctx =CGBitmapContextCreate(nil, rectangleOfOverlap.size.width, rectangleOfOverlap.size.height, 8, rectangleOfOverlap.size.width , colorSpace, kCGImageAlphaNone); UIGraphicsGetImageFromCurrentImageContext returns zero and the resulting image is not created. Am I doing something dumb here? Any help would be greatly appreciated. Regards Dave

  • PHP GD issues with ImageCreateTrueColor and PNGs

    - by DrPheltRight
    I am resizing PNG images using the GD image library function ImageCopyResampled(). It all works fine, I can even keep alpha blending transparency with the use of ImageCreateTrueColor() rather than using ImageCreate() to create the resized image. The problem is, that if I use ImageCreateTrueColor() rather than ImageCreate() the file size of PNG files increases from something like 80kb to 150kb. If I use ImageCreate() the file size stays around the same size, but colors screw! So my question is, how can I retain alpha blending when resizing PNG images without increasing the file size? Oh and I am reducing the dimensions of the PNGs.

  • Le navigateur mobile de Firefox est disponible en version pre-Alpha, pour des tests sur les téléphon

    Le navigateur mobile de Firefox est disponible en version pre-Alpha, pour des tests sur les téléphones Android Depuis quelques semaines, une build précoce de Fennec circulait sur certains sites Internet. La version mobile de Firefox était disponible au téléchargement pour les téléphones Android. Cependant, cette mouture n'était pas officielle puisqu'offerte par un particulier et optimisée pour le Droid. Aujourd'hui, Mozilla pallie à ce manque et rend disponible une build pre-Alpha de Fennec, compatible avec au moins avec Droid et le Nexus One. Cette version est uniquement destinée à la réalisation de tests. Elle ne permet pas encore les mises à jour automatiques, mais Mozilla la trouve assez aboutie pour être décorti...

  • How can I fill a rect with an alpha color using CoreGraphics?

    - by Rits Plasman
    In my drawRect method, I am drawing a PNG image. On top of that, I want to draw a rect with a 20% alpha color, like this: [[UIColor colorWithWhite:0.0 alpha:0.2] set]; UIRectFill(rect); The problem is, that the alpha property seems to get ignored. No alpha is applied at all, just a black rectangle is drawn. How can I fix this? Thanks in advance!

  • How can state changes be batched while adhering to opaque-front-to-back/alpha-blended-back-to-front?

    - by Sion Sheevok
    This is a question I've never been able to find the answer to. Batching objects with similar states is a major performance gain when rendering many objects. However, I've been learned various rules when drawing objects in the game world. Draw all opaque objects, front-to-back. Draw all alpha-blended objects, back-to-front. Some of the major parameters to batch by, as I understand it, are textures, vertex buffers, and index buffers. It seems that, as long as you are adhering to the above two rules, there's little to be done in regards to batching. I see one possibility to batch, while still adhering to the above two rules. Opaque objects can still be drawn out of depth-order, because drawing them front-to-back is merely a fillrate optimization, meanwhile state changes may very well be far more expensive than the overdraw of drawing out of depth-order. However, non-opaque objects, those that require alpha-blending at least, must be drawn back-to-front in order to avoid rendering artifacts. Is the loss of the fillrate optimization for opaques worth the state batching optimization?

  • iPhone: Changing CGImageAlphaInfo of CGImage

    - by TechZen
    I have a PNG image that has an unsupported bitmap graphics context pixel format. Whenever I attempt to resize the image, CGBitmapContextCreate() chokes on the unsupported format (Error formatted for easy reading): CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 32 bits/pixel; 3-component colorspace; kCGImageAlphaLast; 1344 bytes/row. The list of supported pixel formats definitely does not support this combination. It appears I need to redraw the image and move the alpha channel information to kCGImageAlphaPremultipliedFirst or kCGImageAlphaPremultipliedLast. I have no idea how to go about doing this. There is nothing unusual about the PNG file and it isn't corrupted. It works in all other context just fine. I encountered this error just by chance but obviously my users might have similarly formatted files so I will have to check my app's imported images and correct for this problem.

  • Removing WS_BORDER and WS_CAPTION from windows styles doesn't work

    - by lordfrikk
    Hello, I created a small app in C# that removes border and caption from window, then it sets size to the user's resolution and centers it. It's a utility for me to use when I want to play games in windowed mode without being annoyed by the borders. Everything works fine with most games, but I tried to use it on a recently released game Alpha Protocol and it doesn't work. I could almost say that the game reverts my changes, but I'm not sure how to tell if that's true or not. I'm using imported API functions MoveWindow, SetWindowLong and SetWindowPos. Snippet: Win32.MoveWindow(hWnd, 0, 0, Convert.ToInt32(sizeXText.Text), Convert.ToInt32(sizeYText.Text), true); Win32.SetWindowLong(hWnd, GWL_STYLE, Win32.GetWindowLong(hWnd, GWL_STYLE) & ~WS_CAPTION & ~WS_BORDER); Win32.SetWindowPos(hWnd, 0, 0, 0, 0, SWP_NOZORDER|SWP_NOMOVE|SWP_NOSIZE|SWP_NOACTIVATE|SWP_DRAWFRAME);

  • C# GDI - How to check if a Pixel is opaque or not?

    - by rkawano
    I am using a method to get a pixel of the image to check if this point is transparent or not. I am using GetPixel that returns a System.Drawing.Color with a 32bit color info. This struct have the "A" property where I can get the alpha value of pixel, according to this MSDN topic. Code: using (Bitmap bmp = new Bitmap(path)) { Color pixel = bmp.GetPixel(0, 0); if (pixel.A == 0) // This is a fully transparent pixel else // This is not a fully transparent pixel } When I use this method with a fully transparent PNG images it returns 0. When I run with a white semi-transparent images, it will give me other values starting on 1 and up to 86, where 86 are given for images with a 100% alfa (full opaque). But with opaque JPEG images, the "A" property are giving me all sort of values like 56, 71, 86, 129, and others, depending on image. But these pixels are fully opaques! How are the correct way to check if a pixel is opaque or not?

  • Putting a base in the middle

    - by PSteele
    From Eric Lippert's Blog: Here’s a crazy-seeming but honest-to-goodness real customer scenario that got reported to me recently. There are three DLLs involved, Alpha.DLL, Bravo.DLL and Charlie.DLL. The classes in each are: public class Alpha // In Alpha.DLL {   public virtual void M()   {     Console.WriteLine("Alpha");   } } public class Bravo: Alpha // In Bravo.DLL { } public class Charlie : Bravo // In Charlie.DLL {   public override void M()   {     Console.WriteLine("Charlie");     base.M();   } } Perfectly sensible. You call M on an instance of Charlie and it says “Charlie / Alpha”. Now the vendor who supplies Bravo.DLL ships a new version which has this code: public class Bravo: Alpha {   public override void M()   {     Console.WriteLine("Bravo");     base.M();   } } The question is: what happens if you call Charlie.M without recompiling Charlie.DLL, but you are loading the new version of Bravo.DLL? The customer was quite surprised that the output is still “Charlie / Alpha”, not “Charlie / Bravo / Alpha”. Read the full post for a very interesting discussion of the design of C#, the CLR, method resolution and more. Technorati Tags: .NET,C#,CLR

  • About the use of dotted hostname with avahi

    - by BenZen
    Hi I recently discovered avahi. It help you when you when to resolve hostname for the local network. But in my situation i've got a issue. I decided to host a machine called "a.alpha" and a another called "b.aplha". In a near futur i will also use some machine called "a.beta" and "b.beta". My probleme is that from "a.alpha" i can resolv "a.alpha.local" hostname, but currently i can't resolv "a.aplha.local" from b.alpha. So when i will decide to use the ".beta" extension, i will have some issues. Is it normal that the machine "a.alpha" doesn't expos the entire hostname to mdns ? I know i can change the naming method (saying use a-alpha instead of a.alpha). But i like it this way. So the quesiton is: Is it possible to use dotted name in the /etc/hostname and to resolve it using avahi?

  • Hit Testing with CALayer using the alpha properties of the CALayer contents.

    - by Charliehorse
    I'm writing a game for Mac using Cocoa. I'm currently implementing hit testing and have founds that CALayer offers hit testing, but does not seem to implement the alpha properties. As I have at times many CALayers stacked on top of each other, I really need to find a way to determine what the user actually meant to click on. I'm thinking if I could somehow get an array that contains pointers to all of the CALayers that contain the click point, I could filter through them some how. However the only way I've got so far to create the array is: NSMutableArray* anArrayOfLayers = [NSMutableArray array]; for (CALayer* aLayer in mapLayer.sublayers) { if ([aLayer containsPoint:mouseCoord]) [anArrayOfLayers addObject:aLayer]; } Then sort the array by the CALayer's z-values then go through checking if the pixel at location is alpha or not. However, between the sort and the alpha check this seems to be an incredible performance hog. (How would you even check the alpha?) Is there any way to do this?

  • Feedback/bug tracking system for an alpha/beta phase website? [on hold]

    - by randomguy
    I'm developing a website and it's closing onto a private alpha/beta phase. It will be exposed to a small selected group of individuals who will provide a fair amount of feedback. What options do I have for this feedback system? I would certainly like to make it collaborative (excluding email). I could mock up a really simple message board, but would rather use my time elsewhere. The feedback will mainly consist of feature suggestions and bug reports. Edit: Actually, would prefer if it's a free hosted service.

  • How do I fix the alpha value after calling GDI text functions?

    - by Daniel Stutzbach
    I have a application that uses the Aero glass effect, so each pixel has an alpha value in addition to red, green, and blue values. I have one custom-draw control that has a solid white background (alpha = 255). I would like to draw solid text on the control using the GDI text functions. However, these functions set the alpha value to an arbitrary value, causing the text to translucently show whatever window is beneath my application's. After calling rendering the text, I would like to go through all of the pixels in the control and set their alpha value back to 255. What's the best way to do that? I haven't had any luck with the BitBlt, GetPixel, and SetPixel functions. They appear to be oblivious to the alpha value. Here are other solutions that I have considered and rejected: Draw to a bitmap, then copy the bitmap to the device: With this approach, the text rendering does not make use of the characteristics of the monitor (e.g., ClearText). Use GDI+ for text rendering: This application originally used GDI+ for text rendering (before I started working on Aero support). I switched to GDI because of difficulties I encountered trying to accurately measure strings with GDI+. I'd rather not switch back. Set the Aero region to avoid the control in question: My application's window is actually a child window of a different application running in a different process. I don't have direct control over the Aero settings on the top-level window. The application is written in C# using Windows Forms, though I'm not above using Interop to call Win32 API functions.

  • why i change the alpha value of UIImageView but no effect?

    - by chancy
    I am working on a reader app. when you read one magazine, it will display first five pages and download the rest pages one by one. there is a scrollview to view the thumbnail image of pages. At the beginning, if the page needs downloading, the corresponding thumbnail view's alpha value is set to 0.5. when the page is downloaded, i will update the thumbnail view's value to 1.0. I use one operation to download the page, and when one is downloaded i use delegate to set thumbnail view's alpha. But when i update thumbnail view's alpha value, it still the same as the beginning. it seems the alpha has no effect. I wonder is there anything wrong with my code? some snippets are as follows: In the PageViewController.m - (void)downloadPages { DownloadOperation *op = [[DownloadOperation alloc] initWithMagazine:magazine]; op.delegate = self; [[(AppDelegate *)[[UIApplication sharedApplication] delegate] sharedOperationQueue] addOperation:op]; } - (void)downloadOperation:(DownloadOperation *)operation finishedAtIndex:(NSUInteger)index { if (thumbScrollView){ [thumbScrollView viewWithTag:THUMBVIEW_OFFSET+index].alpha = 1.0; } } In DownloadOperation.m - (void)main { // ... NSUInteger index = 0; for (Page *page in mMagazine.pages) { if (/*page doesn't exist*/){ // download the page; if ([delegate respondsToSelector:@selector(downloadOperation:finishedAtIndex:)]) { [delegate downloadOperation:self finishedAtIndex:index]; } } index++; } }

  • Incremental RPM package version "numbers" for x.y.z > x.y.z-beta (or alpha, rc, etc)

    - by Jonathan Clarke
    In order to publish RPM packages of several different versions of some software, I'm looking for a way to specify version "numbers" that are considered "upgrades", and include the differentiation of several pre-release versions, such as (in order): "2.4.0 alpha 1", "2.4.0 alpha 2", "2.4.0 alpha 3", "2.4.0 beta 1", "2.4.0 beta 2", "2.4.0 release candidate", "2.4.0 final", "2.4.1", "2.4.2", etc. The main issue I have with this is that RPM considers that "2.4.0" comes earlier than "2.4.0.alpha1", so I can't just add the suffix on the end of the final version number. I could try "2.4.0.alpha1", "2.4.0.beta1", "2.4.0.final", which would work, except for the "release candidate" that would be considered later than "2.4.0.final". An alternative I considered is using the "epoch:" section of the RPM version number (the epoch: prefix is considered before the main version number so that "1:2.4.0" is actually earlier than "2:1.0.0"). By putting a timestamp in the epoch: field, all the versions get ordered as expected by RPM, because their versions appear to increment in time. However, this fails when new releases are made on several major versions at the same time (for example, 2.3.2 is released after 2.4.0, but their version for RPM are "20121003:2.3.2" and "20120928:2.4.0" and systems on 2.3.2 can't get "upgraded" to 2.4.0, because rpm sees it as an older version). In this case, yum/zypper/etc refuse to upgrade to 2.4.0, thus my problem. What version numbers can I use to achieve this, and make sure that RPM always considers the version numbers to be in order. Or if not version numbers, other mechanism in RPM packaging? Note 1: I would like to keep the "Release:" field of the spec file for it's original purpose (several releases of packages, including packaging changes, for the same version of the packaged software). Note 2: This should work on current production versions of major distributions, such as RHEL/CentOS 6 and SLES 11. But I'm interested in solutions that don't, too, so long as they don't involve recompiling rpm! Note 3: On Debian-like systems, dpkg uses a special component in the version number which is the "~" (tilde) character. This causes dpkg to count the suffix as "negative" ordering, so that "2.4.0~anything" will come before "2.4.0". Then, normal ordering applies after the "~", so "2.4.0~alpha1" comes before "2.4.0~beta1" because "alpha" comes before "beta" alphabetically. I'm not necessarily looking to use the same scheme for RPM packages (I'm pretty sure no such equivalent exists), so this is just FYI.
