Given an image: maxWidth = 400; maxHeight = 200; width = photo.Width; height = photo.Height; How would I go about scaling the image if either dimension exceeds the maximum properties? Here are some test cases: 300x300 : Too tall, but width ok. 500x200 : Too wide, but height ok. 650x300 : Too tall and too wide 300x190 : F...
I have a buddy who runs a web app for people listing cars for sale. There are a few thousand clients who use it, and each client has hundreds and sometimes thousands of rows in the database (some have been on for 5 years with hundreds of cars selling each month, and 10s of rows per sale (comments, messages, etc)). He has run this system ...
Hey all, So the problem I'm having is I have a UIImageView that is 100 x 100 on the iPhone (200 by 200 on the iPhone 4). I'm retrieving an image from a server that is 200 by 200 pixels and setting my UIImageView to it. This looks fine on the iPhone, but looks blurry on the iPhone 4. I think my problem has to do with UIImage scale prope...
I'm trying to layer graphics one top of each other, like an icon over a background, with the second layer (icon) at a certain pixel offset from the top left corner of first layer (background). Since each layer will eventually have its own animation, I'm placing each in its own View. For my implementation I have two ImageViews, one for ...
I am working on a front page gallery which has several images, scaled to fit the page via CSS. The images fade from one to the next (overtop of each other), and will resize if the user resizes the browser to use up the space. The problem is that the image fading performs terribly on most browsers and on all but the newest computers. ...
Hello People, i have implemented a small method that imports an picture on the iPhone screen, but the picture is a little bit to big for the screen. This is the Method: - (void)ladeImage { id path = @"http://172.23.1.63:8080/RestfulJava/pics"; NSURL *url = [NSURL URLWithString:path]; NSData *data = [NSData dataWithContentsO...
If I draw a rectangle of say linewidth=2 and then scale it to double the size of the rectangle, I get a rectangle that has its border double the size of the initial linewidth. Is there a way to keep the linewidth to the perceived size of 2 or the original size. In short, I want to just scale the size of the rectangle but keep the linew...
Hi, Is there a standard solution to scale up a website which runs on PHP + Apache web server ? As in I get a traffic of about 100,000 requests/day as of now. 6 months down the line I expect it to grow to 200,000 requests/day. The first cut solution which comes to my mind is deploying more Apache web servers with mod_php, but something s...
Sites like Twitter and Facebook scale to hundreds of thousands of users. Most of their architectural overviews are available online as talks and slideshows. However, my question is more oriented towards any messaging middleware/layer that these sites use. I understand that it would be different for different sites - but are there any com...
I have a set of 5 million strings. These are currently stored in a single column MySQL table. My application has to perform lookups and check if a given string is in the set. This can of course be done with a HashSet (in Java). But instead of building a custom solution, I was wondering if there are any existing, widely used, proven solut...
I'm confused as to how I can get my winforms to scale properly. When I design a form, in my case WVGA, horizontal orientation, it looks like the upper image below. On the device however, the text is scaled to be a lot larger. Setting a lower fontsize in the designer helps me getting it right, but this can't the the correct way of getting...
I am trying to Draw an Image (JPG, TIFF, PNG) on the background of my user control. My user control will highlight certain portions of the Image using Rectangles. If I draw the image unscaled they are looking correct. But when I draw then Scaled [Fit to Page] then the image is not looking correct. For PNG some times it fails to load the ...
Hello all! I have a Delphi form with TImages on it. Actually, it's a "fake" desktop with "icons" (the TImages). When the user resizes the form (scales it or maximizes it, for example) the icons on the form should align proportionally. Right now, I'm doing something like this with the images: ImageX.Left:=Round(ImageX.Left * (Width / ...
I have a simple web application to conduct online exams for the college students. All questions are multiple choice questions. Around 5000 users will be taking up the exam. My backend is mysql and using PHP as the front end. I want to know the hardware configuration for the servers that will be required to host this application and work ...
I have an image that is 100x100 in pixels. I want to show it twice the size, so 200x200 and I want to do it by CSS and (explicitly) not by the server. Since a few years, images get anti-aliased by all browsers instead of doing a by-pixel scale. Mozilla allows to specify the algorithm: image-rendering: -moz-crisp-edges; So does IE: -ms-...
Hi All, I have tried the following to fit the webpage based on the device screen size. mWebview.setInitialScale(30); and then set the metadata viewport <meta name="viewport" content="width=320, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />" <meta name="viewport" content="width=device-width; initial-scal...

I'm working on simple 2D visualization module for MD simulation code. What I'm trying to do is drawing positions of simulated molecules using: myPainter.drawEllipse(myQPoint,myRx,myRy) And that part works pretty good on my visualization widget. The thing that happened to be a problem is writing text which should represent each molecu...
