  • Why hasn't C# gained much traction within the opensource community?

    - by tmitchel2
    I'm not expecting C# to be on par with say Java or Python in the open source community, but it still surprises me just how far behind it is. 'Multi language' open source repos like google code or github have barely any C# projects in comparison to the other languages I mentioned. I'd like to see C# and .Net shake off that slight corporate feel and move more into the open source arena but I just can't see that happening. I'd be interested to hear peoples opinion on why this might be?

  • Scale an image with unscalable parts

    - by Uko
    Brief description of problem: imagine having some vector picture(s) and text annotations on the sides outside of the picture(s). Now the task is to scale the whole composition while preserving the aspect ratio in order to fit some view-port. The tricky part is that the text is not scalable only the picture(s). The distance between text and the image is still relative to the whole image, but the text size is always a constant. Example: let's assume that our total composition is two times larger than a view-port. Then we can just scale it by 1/2. But because the text parts are a fixed font size, they will become larger than we expect and won't fit in the view-port. One option I can think of is an iterative process where we repeatedly scale our composition until the delta between it and the view-port satisfies some precision. But this algorithm is quite costly as it involves working with the graphics and the image may be composed of a lot of components which will lead to a lot of matrix computations. What's more, this solution seems to be hard to debug, extend, etc. Are there any other approaches to solving this scaling problem?

  • I need a very rapid game engine with as many presets as possible [closed]

    - by GLycan
    I have to make a game about the immune system (with as many grotesque simplifications as I want) in roughly two weeks. I'm thinking of something along the lines of bubble tanks, but I think I can roll with pretty much anything that fits the following: Working engine that handles mouvement, objects The fighting system can be done in any way that allows a bare minimum of configuration Scripting should be, preferably, Python Art should be customizable I'm hoping that there is some existing game that I could adapt. Any sggestions (aside from not leaving projects until later) ?

    Hi Guys, I am getting the data form Parser, In that I am getting a set of urls. Using these urls can I make image url by appending any data values getting from the parser. http://musicbrainz.org/ws/1/artist/f27ec8db-af05-4f36-916e-3d57f91ecf5e?type=xml&inc=url-rels+artist-rels using these url i get data and set of urls.They are not providing image url or thumbnail. So, Is it possible to get or form an image url from parser (http://musicbrainz.org/ws/1/artist/f27ec8db-af05-4f36-916e-3d57f91ecf5e?type=xml&inc=url-rels+artist-rels) and display in the web view.

  • Python/Django: Which authorize.net library should I use?

    - by Parand
    I need authorize.net integration for subscription payments, likely using CIM. The requirements are simple - recurring monthly payments, with a few different price points. Customer credit card info will be stored a authorize.net . There are quite a few libraries and code snippets around, I'm looking for recommendations as to which work best. Satchmo seems more than I need, and it looks like it's complex. Django-Bursar seems like what I need, but it's listed as alpha. The adroll/authorize library also looks pretty good. The CIM XML APIs don't look too bad, I could connect directly with them. And there are quite a few other code snippets. What's the best choice right now, given my fairly simple requirements?

  • Getting a JPEG image from a hex string in XML.

    - by Jesse Knott
    Well here goes, I am trying to collect a picture that is encoded as a hex string in an xml file. I have been looking all over for the answer to this and have not been able to find it any where. Here is what I have now. byte[] bytes = Convert.FromBase64String(FilterResults("PHOTOGRAPH")); MemoryStream mem = new MemoryStream(bytes); Image bmp2 = Image.FromStream(mem); return bmp2; The FilterResults function just returns the string from the XML. I am able to get the string of characters and convert it into a byte[] but as soon as I execute the Image.FromStream(mem) I get an "Parameter Incorrect" error. Any ideas?

  • How to use Haar wavelet to detect LINES on an image?

    - by Ole Jak
    So I have Image like this I want to get something like this (I hevent drawn all lines I want but I hope you can get my idea) I want to use SURF ( (Speeded Up Robust Features) is a robust image descriptor, first presented by Herbert Bay et al. in 2006 ) or something that is based on sums of 2D Haar wavelet responses and makes an efficient use of integral images for finding all straight lines on image. I want to get relative to picture pixel coords start and end points of lines. So on this picture to find all lines between tiles and thouse 2 black lines on top. Is there any such Code Example (with lines search capability) to start from? I love C and C++ but any other readable code will probably work for me=)

  • Why can't I set the Image Source in WPF app?

    - by elmonty
    I'm just learning WPF. I'm using VS 2008. I've added an Image control to my XAML, and I added a GIF file to the project. If I use the XAML Designer's property panel to set the image's Source property, the drop-down list for the Source property contains the following: C:\Sample Project;component/pinHorizontal.gif There are several problems with this: My project, named "Sample Project," is not in the root of my drive. Why is ";component" in there? If I select this value as given, I get the error "Property value is not valid" (yeah, no kidding). If I go into the XAML source and set the Source property manually, like so: The XAML Designer gives me this error: "The file pinHorizontal.gif is not part of the project or its 'Build Action' property is not set to 'Resource'." Why is this task so difficult? How do I assign an image source?

  • Java Swing: how to add an image to a JPanel ?

    - by Leonel
    I have a JPanel to which I'd like to add JPEG and PNG images that I generate on the fly. All the examples I've seen so far in the Swing Tutorials, specially in the Swing examples use ImageIcons. I'm generating these images as byte arrays, and they are usually larger than the common icon they use in the examples, at 640x480. Is there any (performance or other) problem in using the ImageIcon class to display an image that size in a JPanel ? What's the usual way of doing it ? How to add an image to a JPanel without using the ImageIcon class ? Edit: A more careful examination of the tutorials and the API shows that you cannot add an ImageIcon directly to a JPanel. Instead, they achieve the same effect by setting the image as an icon of a JLabel. This just doesn't fill right...

  • How do I stop image spam from being uploaded to my (future) site?

    - by Pete Lacey
    I have in mind an idea for a generally accessible site that needs to allow images to be uploaded. But I'm stymied on how to prevent image spam: porn, ads in image form, etc. Assumptions: I'm assuming that the spammers are clever, even human. I'm skeptical of the efficacy of image analysis software. I do not have the resources to approve all uploads manually. I am willing to spend money on the solution -- within reason. This site will be location-aware, if that helps. How does Flickr do it or imgur? Or do they?

  • Python: Get items at depth? (set library?)

    - by Mark
    I have a nested list something like this: PLACES = ( ('CA', 'Canada', ( ('AB', 'Alberta'), ('BC', 'British Columbia' ( ('van', 'Vancouver'), ), ... )), ('US', 'United States', ( ('AL', 'Alabama'), ('AK', 'Alaska'), ... I need to retrieve some data out of it. If depth is 0 I need to retrieve all the countries (and their codes), if depth == 1, I need to retrieve all the states/provinces, if depth == 2 I need to retrieve all the cities... and so forth. Is there some set library for doing stuff like this? Or can someone point me in the right direction? I started coding up a solution only to realize it wouldn't work for levels deeper than 1 because you have to go in and out of each list...

  • Scaling an image in a scroller resizes the scroller when relative dimension are set to the scroller

    - by tit
    Hi, I would like to position relatively a scroller in my application like below. When I scale the image, I resize the scroller... <s:Scroller width="50%" height="50%" > <s:Group> <mx:Image id="img" source="media/paxRomana005_150dpi.jpg" /> </s:Group> </s:Scroller> If I set absolute dimension to the scroller like below, it does not resize (behaviour I want) <s:Scroller width="400" height="400" > <s:Group> <mx:Image id="img" source="media/paxRomana005_150dpi.jpg" /> </s:Group> </s:Scroller> .. but my intention is to position the scroller relatively to other components. Any explanations/solutions? Thanks

  • Workaround for Outlook 2007 for wrapping text around image with margin?

    - by DavidW
    As we all know, Outlook 2007 uses the Word 2007 rendering engine, causing endless grief when designing HTML email message. [Insert rant here] In particular, float, margin, and padding are - shall we say? - poorly supported. To simulate float so that text wraps around an image, apparently we can simply use: <img src="foo.png" align="right"> The issue is padding/margin. Without padding/margin, the wrapped text butts up against the image which looks goofy. One workaround is to edit the image and add transparent framing that simulates margin. Does anyone know any other workarounds?

  • My image does not load on a jQuery fade in effect even though the div loads.

    - by Konstantin
    jQuery(document).ready(function() { if (useMSIE){ pngfixALL(); }; jQuery(div).show(data_fadeInEffect, 500);return false; // jQuery(div).animate({opacity:1}, 500, 'linear'); }); This is what I have for a fade in effect. When using animate(), the image in the div tag fades in fine. However, when I use show(), the div loads because I can click in that area, but the image itself doesn't load. Why is this happening? I have another area of the code where I click on an 'x' in the image and it fades out using hide(). This works fine.

  • PHP: creating a smooth edged circle, image or font?

    - by Chad Whitaker
    I'm making a PHP image script that will create circles at a given radius. I used: <?php imagefilledellipse ( $image, $cx, $cy, $w, $h, $color ); ?> but hate the rough edges it produces. So I was thinking of making or using a circle font that I will output using: <?php imagettftext ( $image, $size, $angle, $x, $y, $color, 'fontfile.ttf', $text ); ?> So that the font will produce a circle that has a smooth edge. My problem is making the "font size" match the "radius size". Any ideas? Or maybe a PHP class that will produce a smooth edge on a circle would be great! Thank you.

  • How to change the image by click keyboard arrows?

    - by Nitz
    Hey Guys, I have made one project in java. Now in this particular module, i am showing the user , so i am showing them a stock inventory. Now for doing this. As you will see in the screen shot [ i have put screenshot so you can understand well ]. To show the images , i have made one table and i have put labels in that and then i am setting the icon at the label. Now as soon as user click on the any image, then that image i put on big label. But this works perfect on mouse click but client want that , if user navigate the by keyboard arrow keys then in same should be happen. Means : User navigate by key board then it should reflect on that table [user should know that which is currently seleted ] and then as soon as the user navigate by key board arrow events and then click enter then that image should reflect on big label. Here is the Link for that screenshot.

  • Is there a library / tool to query MySQL data files (MyISAM / InnoDB) without the server? (the SQLit

    - by MGW
    Oftentimes I want to query my MySQL data directly without a server running or without having access to the server (but having read / write rights to the files). Is there a tool or maybe even a library around to query MySQL data files like it is possible with SQLite? I'm specifically looking for InnoDB and MyISAM support. Performance is not a factor. I don't have any knowledge about MySQL internals, but I presume it should be possible to do and not too hard to get the specific code out? Thank you for any suggestions!

  • Enterprise Library Validation Block - Should validation be placed on class or interface?

    - by Robert MacLean
    I am not sure where the best place to put validation (using the Enterprise Library Validation Block) is? Should it be on the class or on the interface? Things that may effect it Validation rules would not be changed in classes which inherit from the interface. Validation rules would not be changed in classes which inherit from the class. Inheritance will occur from the class in most cases - I suspect some fringe cases to inherit from the interface (but I would try and avoid it). The interface main use is for DI which will be done with the Unity block.

I need this to work only in new.phtml file, and not in the list.phtml.

  • Why is my background image not displaying properly in IE7?

    - by JAG2007
    Screenshot of the issue: here Webpage in Question: http://cure.org Offending browser: Internet Explorer 7 You'll notice from the screenshot, or if you view this site in IE7, that the background image is not displaying for the content div (#modal-inner-content). Strangely, the image displays in the other divs where it is used (since it's a sprite, I'm using that same image for #modal-top-border and #modal-btm-border). In all other browsers it displays properly, and even in IE8. I cannot seem to find what CSS rule (or lack thereof) I may be using that IE7 is choking on. NOTE: in order to get the modal screen, just click the link at the very top banner of the page that says "login to your CURE account

  • Most optimal way to detect if black (or any color pixels) exist in an image file?

    - by Zando
    What's the best and most flexible algorithm to detect any black (or colored pixel) in a given image file? Say I'm given an image file that could, say, have a blue background. And any non blue pixel, including a white pixel, is counted as a "mark". The function returns true if there are X number of pixels that deviate from each other at a certain threshold. I thought it'd be fastest to just simply iterate through every pixel and see if its color matches the last. But if it's the case that pixel (0,0) is deviant, and every other pixel is the same color (and I want to allow at least a couple deviated pixels before considering an image to be "marked), this won't work or be terribly efficient.
