Ive been hacking away at this portion of a project for some time and I have a Picbox in a panel, I can, Draw on the image no problem, I can pan and then draw on the image, no problem. How ever when I zoom in out out on the image I can no longer draw on the zoomed image. How ever if I try and draw then zoom again, the lines will show up, but in the wrong places
[Code]...
I've created a paint application, and now I want to implement zooming of the picturebox where everything is drawn.

View 2 RepliesI would like to have a picture box, that contains something.. This then can be zoomed in on.. Moved around.. ect. What's the best, most effective way of doing this?
View 3 RepliesSo I've got a picture box and I want to load up all kinds of pictures programmatically , with unknown dimensions. So I pick sizemode Zoom to ensure that the image isn't distorted and I can see all the image. However if the image width is greater than height it vertically centres the image in the PictureBox control's bounds, leaving a gap at the top and bottom.
What I'd like is for the picture to be alighned to the top of the control in this scenario. So the picture will be immediately below a control above it.
Is there any way of acheiving this? Perhaps by over-riding paint event ?
Oh PS: The Picture box is docked to 'fill', otherwise I'd just change it's dimensions in code to have the same aspect ratio as the image.

View 5 RepliesI'm using VS2010 and I've set up a form with a picturebox inside a panel and have zoom working via the mousewheel. The user can also pan by clicking and dragging the mouse. So all good so far. But I've struck a problem.
When I zoom it is anchored on the top left of the image.
What I would like to be able to do is have the user click a point and zoom on that point, or at worst a simple zoom on the center of what is displayed in the picture box.
I am making a program with pictures in its resources... I want to build in a viewer that zooms in and out and I can view every part of the picture.
