Image Processing Problem

83 New Member
guys I have this problem related to image editor..
I 'm developing a project that can resize,add text,move rectangle for crop an image also scroll for bigger image..
the problem is I don't know how to make it display perfectly
this is the code that i've use for all function above
Expand|Select|Wrap|Line Numbers
  1. graphic=image.CreateGraphic
  2. graphic.DrawImage(sourceImage,rectangle,x,y,width,height,graphicunitpixel)
  3.  
but when ever it switch between all function(resize ,scroll,add text)
the display image is not as i expected..
maybe after resize the image scroll event looks like a full image with a resize width or height.. not as a stretch image as expected size
so I want to know what u guys do to create image editor like this..
or u guys know what do i do to fix the code above

Hi All, I'm facing problem displaying image of size 5000X5000 .My window size is smaller than image size so i'm not able to see the complete image.i can use scroll bars to view the image but i need to rotate the image and the see the result everytime. For this my boss has given me suggestion to display only 20% of the image on window ,and rotation has to be applied to original copy.

I read recently that: "if a before-image was made before an interruption in database processing, you use the before-image dump & simply begin processing again from just before the last transaction. Any checkpoints are irrelevant." I'm not a dba here, so bear with me... What I don't understand is, why are checkpoints irrelevant when you did a before image dump? Why not begin from the last checkpoint? Probably part of my problem is...

Hi! I am developing an application in ASP.NET that takes an image, that have been created with a digital camera or camera phone, and processes it, to get data from it. The image taken by the user will be of a square in some kind of magazine or newpaper, with a white background and the border of the square should be black. What I am trying to do is to find the square, or the corners of the square, in the image, using ASP.NET code. If the...

Hi, we are planning to rewrite an extisting C++ image processing application/library in C#. Now several question arouse where I hope you can help me: So far we allocated a block of memory as image buffer, handed this to a driver dll and got raw image data back in this buffer. We then handed this buffer by reference to another C++ dll to do base image processing on it. Alternativly we copy an area of the whole image to a newly...

Okay, so here is the situation. I have need to do some on-the-fly image creation. I have everything working great except for the last part of it, applying a perspective type transform to the image. The transform will take a rectangular 2D image and transform it to a 3D representation in 2D. Please see the link to see what I am trying to do: http://seanberry.com/transform.png I have PIL v1.15 installed which has a PERSPECTIVE...

Hello all, I am currently implementing a fairly simple algorithm. It scans a grayscale image, and computes a pixel's new value as a function of its original value. Two passes are made, first horizontally and second vertically. The problem I have is that the vertical pass is 3 to 4 times slower than the horizontal, although the code is _exactly_ the same in both cases?! The code itself is very simple. There are 2 loops to scan through...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
