Resizing Images And Aspect Ratio In .net?

Aug 14, 2011

I'm using a web cam that takes 320 X 240 pictures. This sort of gives the picture a "landscape" look to them, and I need to re-size the pictures to a 169 X 225 "portrait" picture. Its for a badge program. Anyway, when I re-size the pictures, they get all scrunched up because of the difference in aspect ratio. Is there a way to re-size the image and the aspect ratio at the same time? Would this be considered cropping or resizing?

I mainly use VB, but if someone has a good example in C#, ill take the time to convert it.

Cropping Tool For Picture And Aspect Ratio

May 18, 2012

How can I build a cropping tool such as the one in Office Picture Manager as seen below? Notice that as soon as the Aspect ratio is selected a cropped area shows on the picture that can be dragged to the perfect position creeping the aspect ratio in tact. This is why I wanted somehow to link my app. to Picture Manager. I want the picture to open in Picture Manager, cropping tool already selected, ready to be dragged to the perfect position. Unless you have some code that can do jut this.

Maintain Aspect Ratio Of Container Form

May 21, 2010

I have the need to maintain a 4:3 aspect ratio on a Video control on a form. The forms (there could be up to 16 in a 4x4 layout) should all maintain a 4:3 aspect ratio when resized depending on clients monitor/resolution. The forms have a border and will keep them. The control is set to fill the form and is the only control on the form. Here is code that I use to create the initial layout:

C# - Start With Aspect Oriented Programming?

Mar 27, 2009

So having read some of the PostSharp documentation presented as an answer to my previous question regarding passive logging ([URL]), I am led to my next question: Where is a good place to start learning about Aspect Oriented Programming - I've done some searches on Google and I've read some articles - including the article regarding the topic on Wikipedia, but a lot of the material seems to assume you have a basic understanding of some of the terms which I seem to be missing, and that which doesn't just dives straight into integration leaving me not understanding what exactly it is I'm integrating.

Does anyone have any decent material targeted at someone who's never heard of Aspect Oriented Programming before today learn about the core concepts, terms/keywords etc? Even a birds-eye - i.e. These are the core concepts, keywords to look out for, what they stand for and how they fit together. After that, I can probably make some decent headway on my own. I'm most interested in AOP in relation to .NET development,

VS 2008 Visual Aspect Of Controls?

Mar 25, 2010

I would like to ask some questions about the controls placed on forms :1) I noticed that VB .NET can create applications with XP visual style . If the "Application framework" is not activated , though , the controls look like those used in Win98 . This is useful to me sometimes . However , I wonder , is it possible to also see those controls in Win98 style during design time ? I am asking because during design time the controls on forms are represented with XP style no matter what style is selected .

This usually creates a problem to me because I can't properly set the dimensions for labels in order to fit their text . So , is there a way to also see those controls in Win98 style during design time ?2) Now this might be funny : I like both styles , so is there any way I could use both of them in the same project ?

Calculate Ratio On Startup Of The Program?

Apr 4, 2009

Im making a small tool that helps gamers keep track of their kills and deaths, and their kill/death ratio.I calculate ratio on startup of the program, straight after kills and deaths are loaded off my website.Dim ratio As Decimal ratio = Val(txt_kills.Text / txt_deaths.Text) At the moment, kills = 172 and deaths = 145. Ratio results in 1,1862068. How can I round this number up and turn this into a number with 2 integers after the dot? ( 1.19 ) I tried a hundred things so far but I cannot figure this out.

Fibonacci Numbers And The Golden Ratio

Oct 15, 2011

So I need to write a program that will approximate PHI (the golden ratio) using Fibonacci Numbers. It has to be within a negative power of 10 (between -1 and -16) oh PHI. So for example, if I put -2 into the input, the approximation of PHI would have to be with 10^-2 of the number that we're using of 1.618033988749895. Also, we need to show how many Fibonacci terms that were used to get to that number and the difference that the number that we approximated is to PHI.

VS 2008 Copying Only The Visual Aspect Of A Control?

Mar 20, 2011

I notice when I copy a control over a form (i.e. by copy - paste) , I don't only copy the visual aspect of the control but also the code is altered in relation with the new control . For example , lets say we have a Button on the form which is supplied with a sub for handling the Click event . If I copy the button then the existing sub will handle the new button too ! But I don't want that , I only want to copy the button (i.e. it has some specific color , dimensions , font etc and therefore it's faster to copy an existing one instead of creating a new one)

[2008] TONS - Set Of Default Images And Then The User Created Replacement Images

Feb 11, 2009

The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

VS 2010 :: Make An Application To Save Images [or Download Images] To Local Hard Disk

Aug 12, 2010

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
