I have a picturebox on a form. The image in the picturebox is actually a report. I want it so if the user clicks on it it will zoom larger --- while the picturebox remains the same size. Of course, the entire image will no longer be seen. So I also want to be able to drap this image around with the cursor. The examples I've found for picturebox zooming cause the picturebox itself to get bigger and smaller. I need it to be like an Access report. Click on the report and it gets bigger. Click again and it goes back to the full image. Does anyone know of an example or tutorial in VB.Net for this type of zoom-with-fixed-size picturebox function?
i have map of a State, i need to let the user to Zoom in amd Zoom out and show some buttons on the Picture if we zoomin or zoomout the buttons also will be moved according to the location like google map how to achive this?
I finished making a top view shooter game that shows the whole map from above. The map is kind of big so the characters that move around are kind of small. Is there anyway to zoom in on the main character (a picture box), but still keep all the original properties of the form?
So 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.
My report is an image in a picturebox. I want it so if the user clicks on it it will zoom larger --- while the picturebox remains the same size. That's important. The examples I've found for picturebox zooming cause the picturebox to get bigger and smaller. I need it to be like an Access report. Click on the report and it gets bigger. Click again and it goes back to the full image. Of cours when you're zoomed in, the perimeter of the report is not visible. So I'd like to be able to drag the image as well so the unseen portions can be seen.
I am trying to perform Zoom and Pan the image in Picture box using the following The Width and Height of the picturebox is (1024,1024).
Private Sub Picturebox1_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Picturebox1.Paint If Mouse_Operation = "ZOOM" then ZoomWidth = 1024 * Total_Zoom_value ZoomHeight = 1024 * Total_Zoom_value
Total_Zoom_Value and (imgx, imgy) are calculated based on the mouse movements on the picturebox.Now I am able to do the PAN operation after Zoom operation. But If i try to do Zoom operation after PAN operation, I am not able to Zoom the image from the PAN co-ordinates (imgx, imgy). I am not getting how to retain the image drawn using e.graphics.drawimage.how to do the operations on e.graphics.drawimage.
I'm considering a personal learning project. Using .NET(preferably VB) I want to build a simple desktop app that's only function is to display comics, like CDisplay, but with more advanced navigation. I want to be able zoom in by clicking on certain areas of an image, individual panels for instance, and have the zoom area automatically snap to the panel and blow it up. The images are usually in a standard format like .jpeg, .png, etc..
Something like this is what I'm going for: [URL]
I'm not even sure what this is called? Image mapping? Tone mapping maybe? Is it possible to do this within .NET or would it require some kind of outside library? Code samples would be nice, but obviously this is pretty vague request.
Im looking for an image viewer that supports most types of image formats, including PDFs, and has the ability to rotate/zoom, and draw on an image. I've been looking but to no avail. Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features? The main problem that I am running into is the lack of the ability to draw on an image. Im still sort of a newbie to .NET,
I would like to prepare a preview window to zoom inside a picturebox. In my form, I have a picturebox (name picSource1) and inside the same picturebox, I have some other pictureboxes (like picsmallSource1). All of them make a detailed whole photo. My aim is to make a new form with a new picturebox (name it picDestination) so that when mouse comes over the source picSource1 (and of course the other small pictureboxes inside this), Form2 becomes visible and picDestination shows the zoomed part where the mouse cursor shows. So while the mouse moves over the image, the new picturebox shows in real time the zoomed version.
Public Class ImageEventArgs Inherits EventArgs Private _image As Image
This code works very fine but I should revise it to somehow "overlay" the picturebox1 with other small pictureboxes, isn't it?

I drew an image in a picturebox with the image height as picturebox height and image width as picturebox width. The image is placed somewhere on the center of the picturebox. My intention is to scale the image to fit to the picturebox.
I'm trying to update pictures boxes with images of controls stored in an imagelist owned by a control. The images stored in the control.imagelist do not showup in the picturebox. I'm working on simplifying the code to post, but for now could use help.If I store the image in a member variable owned bythe control it woks fine.Something to do with persistance of images in control owned imagelist? [code]
i'm lost on this code.. i have a picturebox that swaps 2 images, depending on the action, file_red and file_green.. what i'm trying to to is, if a picturebox switches a image or not, to be able to detect that and have textbox8 add a line with the detection.
I want to Use Picturebox_MouseCaptureChange Event Arg to zoom in on a peice of a PictureBox.Image. The Help Search says there is a zoom and a pan function on Systems.Windows.Controls But I cannot find it in the add reference component of the Visual Basic 2008 edition...I have one program that I did that allowed me to zoom using a TrackBar here it is...
The problem is that I cannot get the trackbar to zoom any closer that the top left side of the controler....I need to zoom and then pan around the image.
