In summary, to create a successful zooming application, you should first decide on the type of zoom you want to create and then break down the individual components needed to make it work. This includes things like the zoom meter, image processing, and user interface. You should also research and understand different algorithms and techniques for transforming images and handling user input. Finally, consider optimization techniques to improve the performance of your application.

Hi every one.
I am tying to build a Zooming application that is a zoom by level type.
i manege to create the following:


  1. [1]first i to build a zoom Meter that spited overall zoom into Levels and sub zooms for each level.
    [2]each level represent a set of divided image increasing by level and ordered by Level,column and row.
    [3]and i create procedure that shift image to zoom center by this transformation:
    Z(x1,y1)=(x1-x2,y1-y2):x1,y1 center before zoom;x2,y2:center after zoom.
    [4]then i create a procedure that combine's the image.
    [5]and procedure to calculate Subtractive of a point in other level by this transformation:
    S(x1,y1)=((x1*d2)/d1,(y1*d`2)/d`1):x1,y1 target point; d1,d2 old dimension;d`1,d`2: new dimension.
    [6]and procedure that detects the viewed parts of image in the view port(putting the result in two dimension array of Boolean [Column][Row])

then during my analysis to the program i ran into many problems like:

  1. [1]what is the effective methods to creates fixed frame (by dimensions of the form) that represent a 'view' part of the image, that capable to pan throw the total image ,zoom from /to image plus move throw the levels, with 'aware' for border updates.

    [2]effective algorithms for transformation like(move ,zoom) for my levels;

if you please, i need some help in this manner ,please put some hint to solve my problem.

thank you very much for reading may request.

The best way to approach this problem is to break it down into smaller, more manageable pieces. You need to devise a plan for how you will go about creating the zooming application. First, you should decide what type of zoom you want to create. For example, do you want to create a simple zoom, or a more advanced zoom with different levels and features? Once you have decided on the type of zoom you want to create, you can then start to break down the individual components that are needed to make it work. This includes things like the zoom meter, the image processing, the user interface, and any other features you may want to add. Once you have broken down the individual components, you can then begin to look into the specific algorithms and techniques needed to make it all work. For example, you will need to research and understand the various types of image processing algorithms available, and the different methods of transforming images such as scaling, rotating, flipping, etc. Additionally, you may need to familiarize yourself with different ways of handling user input, such as mouse events, keyboard events, and touch events. Finally, you should consider any optimization techniques that you can use to make your application run faster and smoother. This could include things like caching images, pre-processing data, and optimizing image sizes. With all of these pieces in place, you should be able to create a successful zooming application. Good luck!
