  • how to load an image to a grid using pygame, instead of just using a fill color?

    - by yao jiang
    I am trying to create a "map of a city" using pygame. I want to be able to put images of buildings in specific grid coords rather than just filling them in with a color. This is how I am creating this map grid: def clear(): for r in range(rows): for c in range(rows): if r%3 == 1 and c%3 == 1: color = brown; grid[r][c] = 1; else: color = white; grid[r][c] = 0; pygame.draw.rect(screen, color, [(margin+width)*c+margin, (margin+height)*r+margin, width, height]) pygame.display.flip(); Now how do I put images of buildings in those brown colored grids at those specific locations? I've tried some of the samples online but can't seem to get them to work. Any help is appreciated. If anyone have a good source for free sprites that I can use for pygame, please let me know. Thanks!

  • Custom view in ListView disappears while scrolling in Android

    - by troorl
    Hi. I wrote a simple custom view for rows in ListView. It works fine, but when I try to scroll the list, I see only white rows without content. And when scrolling is over, rows continue to show again. This is how I draw a custom view: @Override protected void onDraw(Canvas canvas) { if(poster != null) { canvas.drawBitmap(poster, padding, padding, paint); } canvas.drawText(title, 55 + padding, 16 + padding, paint); } Maybe I missed something? P.S. This is short screencast (400kb) http://dl.dropbox.com/u/190203/test.mpeg

  • Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.

    - by Kp
    I get the following error in Chrome every time I try to run my script on a Linux server: Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. In Firefox it just shows a blank white page. Whenever I run it on my local test server (IIS on Windows 7) it runs exactly the way it should with no errors. I am pretty sure that it is a problem with the imap_open function. error_reporting(E_ALL); echo "test"; // enter gmail username below e.g.-- $m_username = "yourusername"; $m_username = "username"; // enter gmail password below e.g.-- $m_password = "yourpword"; $m_password = "password"; // Enter the mail server to connect to $server = '{imap.gmail.com:993/imap/ssl/novalidate-cert}INBOX'; // enter the number of unread messages you want to display from mailbox or //enter 0 to display all unread messages e.g.-- $m_acs = 0; $m_acs = 10; // How far back in time do you want to search for unread messages - one month = 0 , two weeks = 1, one week = 2, three days = 3, // one day = 4, six hours = 5 or one hour = 6 e.g.-- $m_t = 6; $m_t = 2; //-----------Nothing More to edit below //open mailbox $m_mail = imap_open ($server, $m_username .

  • Using SWFObject, the flash moves 1 pixel to the right on Firefox

    - by jeffkee
    Please check this page: http://islandhideaway.weebly.com/ For whatever reason, the flash slideshow moves over 1 pixel when opened in Firefox on my Mac. All other browsers render it fine, but only on Firefox it leaves a 1 pixel white gap on the left! I am using the most recent version of SWFObject. This unfortunately is a garbage Weebly site and I cannot use jQuery in the system so I can't do a real gallery... so let's save the whole "don't use Flash for that" pep talk. It's a favour for a friend and I am already aware of better ways to do it. :)

  • Blending Three Images into Graphics Context Using Alpha Blend Mode kBlendModeOverlay

    - by steganous
    Does kCGBlendModeOverlay not work exactly like Photoshop's Overlay blending mode? I'm trying to overlay three images into a graphic context via: [uiimageGreen drawAtPoint:CGPointMake(x, y) blendMode:kCGBlendModeOverlay alpha:1.0]; [uiimageRed drawAtPoint:CGPointMake(x, y) blendMode:kCGBlendModeOverlay alpha:1.0]; [uiimageBlue drawAtPoint:CGPointMake(x, y) blendMode:kCGBlendModeOverlay alpha:1.0]; In the end, if I overlay just two of the three, the result is much closer to my desired output color in places where both images intersect. Adding the third image, however, causes the first-drawn image's color to be dominant in the resulting mix of colors. (e.g. in the above code, green comes out dominant, when the result should actually be white) Do you get the same result if you try?

  • problem with css showing the divisions of the page

As you can see in the url above. Please help, why do I see those lines everytime I put those css scripts

  • CSS Vertical Spacing Issue (Margin?) - Vertical Space Between Two Divs

    - by Sootah
    I've got the layout of my site mostly done. On the domain I'm testing this layout on - http://networkgenius.org/ - there is a vertical space separating the content-wrapper div and the menu div. I have the margins set to 0px for the vertical spacing, and this is the only area that is separated like it is. I'd like the white content area to be pressed up right against the bottom of the menu, so that none of the body's background shows between them. What am I doing wrong?

  • Tinymce extended_valid_elements for BBcodes?

    - by Emily
    I use Tinymce with BBcodes plugin so the tags used in the editor are [B] [U] [I] [quote] [color]. If you are familiar with TinyMce there is a great option to filter all unwanted tags when pasting to the editor. Unfortunately i think this is not working for BBcodes mode, what i want is to remove any <TAGS> Or Other Unwanted BBcodes such as [url] & [img] So, my white list is : [B] [U] [I] [quote] [color=XXXXXX]. I'm already filtering in the server side, but i want this to be implemented in the client side too, So by example if someone copied from a webpage a mix of images and urls and formatted text, every image will be stripped and every url will be "unclickable" directly after pasting. Note: this is one of my failed attempts : extended_valid_elements : 'b,i,u,quote,color' Thanks

  • Android - Camera functionality howto

    - by teepusink
    Hi, I'm using the example from the SDK (CameraPreview) and also the example from this site http://marakana.com/forums/android/android_examples/39.html When I run it, both gives this error "The application AppName(appname) has stopped unexpectedly. Please try again". I can't run the debugger either because it's always "Waiting for debugger. Force close". (I have debuggable=true in the manifest file) The phone I have is a Nexus One. Running on the emulator gives me the black and white squares with a moving square. (So I assume it works on the emulator?). Even on the emulator it gives me the "stopped unexpectedly" error 50% of the time. Does anyone know what caused it? Thanks, Tee

  • Graphical net and text

    - by chesheerkys
    Hello! My task is to make a control, that behaves itself like RichTextBox, but contains a graphical net. The only task, this net is solving, is to be visible. It should be solution in overriding OnPaint method, but it doesn't. This code: protected override void OnPaint(System.Windows.Forms.PaintEventArgs e) { base.OnPaint(e); ...//drawing a line } gives me RichTextBox without of text This code: protected override void WndProc(ref System.Windows.Forms.Message m) { base.WndProc(ref m); if (m.Msg == 15) { Graphics g = this.CreateGraphics(); g.DrawLine(new Pen(Color.White, 1), new Point(0, 0), new Point(400, 400)); } } sometimes draws extra lines Actually since these two ways don't work, I don't know what to try. Waiting for your advices :) BR Dmitry P.S. I’ve heard a lot about great opportunities of WPF, but I’m not really common with this technology and don’t know what to start with. P.P.S. Sorry for my English, it’s not my natural language.

  • Syntax highlighting in MS Word document

    - by ArunSaha
    I want to insert some C/C++ source code into a Microsoft Word document. I have no problem in copying the code from source file and pasting into Word. I can do fixed-width. But, in Word, I see the code in black-and-white format; I loose the syntax highlighting as I get in the source code editor (for me, gvim). So, my question is, is there any way to do syntax highlighting of C/C++ source code in MS Word?

  • UITableView's cellForRowAtIndexPath is not getting called after low memory warning

    - by Jinesh
    I am new to COCOA and Objective C. I am working on an application which have two controllers with one table view in each, clicking an item form this table will lead to another controller to be pushed to the stack. All was working fine till i started handling low memory warning in app delegate. What i am doing in app delegate's applicationDidReceiveMemoryWarning is, deleting all of my model and popping out all controllers to its root view using popToRootViewControllerAnimated. Now my problem starts, once low mem warning is received table's cellForRowAtIndexPath is not getting called. All other methods of UITableViewDataSource is properly called. What i get on screen is a blank white screen. I am testing my app in iPhone OS 3.0 and development is done in Xcode V 3.1.3. Hope you guys can help me to nail this. Thanks in advance, Jinesh.

  • How to wrap text of html button with fixed width

    - by Peter
    I just noticed that if you give a html button a fixed width, the text inside the button is never wrapped. I've tried it with word-wrap, but that cuts of the word even though there are spaces available to wrap on. How can I make the text of an html button with a fixed width wrap like any tablecell would? <td class="category_column"> <input type="submit" name="ctl00$ContentPlaceHolder1$DataList1$ctl12$ProCat_NameButton" value="Roos Sturingen / Sensors" id="ctl00_ContentPlaceHolder1_DataList1_ctl12_ProCat_NameButton" class="outset" style="height:118px;width:200px;font-size:18px;color:#7F7F7F;width:200px;white-space:pre;" /> </td> the css classes do nothing but adding borders and modify the padding. If I add word-wrap:break-word to this button, it will wrap it like this: Roos Sturingen / Sen sors And I dont want it to cut of in the middle of a word if it is possible to cut it off between words. Thanks

  • Flashing window in gnu screen

    - by gotts
    I really like gnu screen but there is a problem in my environment when I use it. Examle: username@domain:/var/www$ l Display all 130 possibilities? (y or n) when you click [Tab] to perform autocompletion there is a screen flashing for a very short period of time(looks like white screen but I can see it for a very-very short time). There isn't any problems with that when I execute the same action in normal/non-screen environment. This is what my .screenrc looks like: attrcolor b ".I" termcapinfo xterm 'Co#256:AB=\E[48;5;%dm:AF=\E[38;5;%dm' defbce "on" term screen-256color-bce

  • Faster way to iterate through a jaggad array?

    - by George Johnston
    I would like to iterate through an array that covers every pixel on my screen. i.e: for (int y = 598; y > 0; y--) { for (int x = 798; x > 0; x--) { if (grains[x][y]) { spriteBatch.Draw(Grain, new Vector2(x,y), Color.White); } } } ...my texture is a 1x1 pixel image that is drawn to the screen when the array value is true. It runs decent -- but there is definitely lag the more screen I cover. Is there a better way to accomplish what I am trying to achieve?

  • Cloud Agnostic Architecture?

    - by Dave
    Hi, I'm doing some architecture work on a new solution which will initially run in Windows Azure. However I'd like the solution (or at least the architecture/design) to be Cloud Agnostic (to whatever extent is realistic). Has anyone done any work on this front or seen any good white papers/blog posts? Our highlevel architecture will consist of a payload being sent to a web service (WCF for instance), this will be dumped on a queue (for arguments sake) and a worker process will grab messages off this queue and proccess them. There will be a database of customer information which we'd ideally like to keep out of the cloud however there are obvious performance considerations. Keen to hear other's thoughts. Cheers Dave

  • Using CSS, how can I make overflow:visible; contents overlap adjacent <td> cells?

    - by Structure
    I have the following CSS style code for my table: td { overflow: hidden; white-space:nowrap; } td:hover { overflow: visible; } However, when I hover over a <td> element whos contents (text) are hidden, the result is that the contents become visible but are behind the content of the adjacent cell (right side). I do not think that z-index can be applied to table cell elements, so is there a CSS attribute that I can specify within my td:hover style which will make the content of my <td> tag overlap the content in adjacent cells?

  • Variable font height via tables in LaTeX

    - by Hooked
    I've been looking for a more elegant solution to the following typesetting problem. Consider those banners found in print media where the text is aligned like: B I G T E X T small text small text small text m o r e m e d i u m t e x t The font sizes are adjusted so that the height is scaled down for longer lines of text such that each line has equal width. I've written a small script that runs each line separately, compiles, crops the resulting pdf and then \includegraphics each in a table. This gives the desired effect but requires an both an outside script and pdfcrop (which only crops to a white bounding box). Since much of LaTeX is self-aware, I imagine it would be possible to have it recognize the width of a box and scale it appropriately so that any text fits exactly into the desired width. Any thoughts or ideas on how a pure LaTeX implementation might work?

  • CSS: float:left with a margin-right doesn't push all elements away

    - by Paul Tarjan
    I'd like all my content to flow around an image. To do this, I simply did img#me { width: 300px; float: left; margin-right: 30px; } This works for text wraping, but other elements go behind it. For example <style> h2 { background: black; color: white; } </style> <img id="me" src="http://paultarjan.com/paul.jpg" /> <h2>Things!</h2> Then the h2 background flows right past the 30px margin. How should I do this instead? Live example: http://paulisageek.com/tmp/css-float.html
