i have a question to do with vb.net. i have a picturebox with zooming capabilities. but i want the zoom button to zoom a certain percentage with each click. for example:
1st click zoom image(1.5)
2nd click zoom image(2)
3rd click zoom image (2.5)
[code]....
how can i zoom an image inside a picturebox? and i also want to know how can i make a picture inside the picturebox draggable while at the same time, it can be zoomed in and out.
my goal is to crop an image inside the picturebox and i can zoom and drag the image inside if necessary
I have a picturebox with zooming/pan capabilities. I am now starting with the zoom. I did that by:
getting the mousescroll event( up or down)
add height and width to the picturebox
get the pixel coordinates of mouse inside the image.
my problem is that, when i change the size of the picturebox, the pixel coordinates in the picture is not the same with the previous image without zoom. I need the coordinates to be the same even the picture is zoomed.
i need to add zooming option for picture box with C#

View 2 RepliesI managed to combine two .png images into one, and then display the result in a pictureBox image.However, the pictureBox seems to scale up my image! Makes it bigger!The pictureBox size is 96x128. The two images I have combined are 96x128. The pictureBox's SizeMode is set to "Normal"I have noticed that even though the pictureBox's image seems to be zoomed, it is cut to keep the 96x128 rect. But I don't want it to be zoomed...
View 6 RepliesI've found an example of what I'm trying to do. The form will have 2 picture boxes. The first will be the original image. The second will have the zoomed image. Once I move my mouse over the first image, it must display a zoomed image in picturebox 2. I've attached the code that I found (written in C#) of what I'm trying to do. I've converted the code for me to VB. I want my first picturebox to be smaller than my second one. And the attached example shows that the first picturebox is bigger than the second one. I've never tried something like this, or drawing images etc. Just resize the 1st picturebox to be smaller that the second one, move with your mouse over the first one, and will see what I mean. I don't want to click on the image to have it zoomed or use the mouse wheel. Just want to hover over the image and display the zoomed version..
