Set picturebox size to size of image file?
View 5 RepliesI'm trying to change the size of the image in a picturebox, without resizing the picturebox?
View 3 RepliesI'm currently in the process of making a dynamic signature generator, and I want to make the user be able to see what he would get... So I thought of putting a browse button and allowing them to load up a background image for their signature, but I also want the picturebox to resize according to that image's size. I need them to be the same size because of the image's X, Y are needed for the signature.
So I'm using this code for that:
LocalMousePosition = PictureBox1.PointToClient(Cursor.Position)
xy.Text = ("X=" & LocalMousePosition.X & "," & "Y= " & LocalMousePosition.Y)
It works fine, but it only gets the coordinates for the picturebox, not the actuall image, so I think if the picturebox is the same size as the picturebox it would get them just fine..

View 4 RepliesIs there a way to tell the DISPLAY size of an image in a picture box? If the PictureBox.SizeMode=Zoom, the picture sometimes is not displayed as big as the picture box is, and is sometimes displayed smaller, or larger, than the actual image is. I just want to know what size it is actually displaying as.

View 2 RepliesHow do i center an image at all window sizes? My Window is borderless and maximized so its size obviously differentiates between resolutions. I'm having trouble centering an image directly in the middle of the screen and making it stay there regardless of the size of the window. Docking isn't working neither is anchoring and hoping there is an easier way around this?

View 8 RepliesHow should I handle image files of various sizes (<1 mb upto 15mb) within a mobile application that I am developing? Currently, I am displaying the image full size using a ASHX file inside of an ASP Win Form using the ASP Image Class. So basically what I would like to know how should I go about dealing with these sometimes vastly different image sizes. Would copying the image to be displayed and then scaling it on the server to whatever dimensions I decide and then displaying it in the browser be a better way of "handling" images especially in an mobile browser?
View 1 RepliesIm trying to resize a picturebox dynamically using .size.height and .size.width Its not working. This is the error message: "Expression is a value and therefore cannot be the target of an assignment." Never used height and width before. Been trying to find the answer, but it seems beyond me. Im sure its easy. Anyone know whats wrong with this?

I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).
I have a specific image that I want my application to look for on a specific window. I've done something similar to this along time ago with VB6, but it was slow, and it was checking for specific points in the picture rather than the whole image itself (for speed reasons). I named this image "Image1.jpg" and I want to compare it to the window with the handle "001C08F2" and class "SunAwtCanvas"
View 19 RepliesI 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?
