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.

I'm wondering how to maintain the aspect ratio (i.e.: 16x9) of a window in WPF upon resize--if possible in a way that leverages MVVM.

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'm a little confused on where to begin. I mainly use VB, but if someone has a good example in C#, ill take the time to convert it.

I use this code for maintaining aspect ration of form when resizing:
Public Class Form1
Public Structure Rect

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:

I have a folder of images that I would like to loop through them all and resize each one to have a max of 100 in width or height, I have looked at the samples out there but none indicated where I can set the width and/or height and it will do it automatically, I would like to save the file in a new directory once I resize it.

If i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.

how would I allow my screen capture to crop and capture only a particular area of a screen?The user should be able to select the area they want to crop. It would be good if the cursor changers to a plus like other screen captures and also the screen is all paused so the user can select the area they want.v

I'm playing with creating thumbnail images for my photo website using VB rather than Photoshop.[code]However, I'd really like to be able to crop images to a square shape - same width and height - from a starting image that might be 1000 pixels wide x 667 high, 500 wide x 750 high or already square and around 750 x 750. In other words, crop a square from the central area of a jpeg image, irrespective of it's exact size.

I'm in essense trying to make my own interpretation of the NES hardware, so I can make a game that ideally would resemble what a NES game would look like. I'm currently stuck with how to adjust how to draw the playfield to the video memory (back buffer).
Backbuffer: The NES had restrictions on the nametable, or backbuffer. For my example, the backbuffer is 256x240pixels big, or the size of one screen. If I drew this to the TV, it would fill up the screen perfectly. Now, if I drew this to the screen with an offset of X=5, the entire image would be shifted and would wrap around the screen.
For example.....
ORIGINAL, NO OFFSET: DRAWN WITH OFFSET OF X=5:
ABCDEFGHIJK GHIJKABCDEF
DRAWN WITH OFFSET OF X=-5:
FGHIJKABCDE
The screen is split up into squares 8x8 pixels each, totalling 32x30 rows and columns. (256x240 pixels). The offset is represented in pixels - not columns; so in theory, I could offset the screen by 5 pixels and every column would be shifted to the right by five pixels.
Level Design: My stages are made up of screens, containing data that is represented in 16x15 rows and columns, each by 16x16 pixels. This is to emulate how many NES games stored level data - each tile holds info about what should be in each 8x8 block.
E.g.:
AA
BC with A,B,C,D representing what 8x8 graphic should go where
Level design is represented by this as well, with each number being a different screen and - meaning nothing, null.
-----
-123-
---4-
--54-
-----
Character Replacement: This is easy. I already know how I can determine which table, row, and column my characters are on based on their absolute positioning. I can also determine the relative positioning within the screen.
With this info, I can easily figure out which columns are to the left and right of the character, if any (if the character is at the left side of screen 1, thered be no more level left). How do I draw my levels to the screen, so that they scroll from one to the next. It would be relatively easy to draw one full screen at a time, and when the character gets to the edge just flip to another screen. However, the problem I'm conceptually having is that I need to 'stream' the level data onto the screen. That, lets say the character moves 24 pixels to the right. The BG needs to move as well. So, I need to adjust the scrolling of the backbuffer by 24 pixels.
However, just scrolling alone will cause the screen to wrap over, diplsaying old portion of the level. So, while scrolling I need to make sure to draw new pieces of the level to the back buffer. But before I can do that, which tiles need to get drawn first. And if the person goes 24 pixels to the left, I need to redraw tiles onto the backbuffer and change the offset accordingly as well. And let's not forget that if the character moves right and there's no more level data to be drawn, there should be no offset but instead the character gets closer to the side of the screen (instead of being centered in the middle of the screen via the X axis).

In my code I am taking a screenshot of a CAD screen. The image consists of various colored entities on an all-black background. I would like to find the extents of the non-black pixels in all four directions & crop the image to those extents or maybe a few pixels beyond.

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,

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 ?

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.

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.

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)
