The object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties

View 2 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..
I have some problem about image sizing, citing the process: I've create 2 button and picture box. The button1 load opendialog to load image then the image will be viewed at picturebox and the button2 will save to sql table. My problem is how could I resize the image before saving to sql table.
My code:
Button1_click
Picturebox1.image=image.fromfile(opendialog.filename)
end
Button2_click
--before saving
dim myImage as Image=Picturebox.image
How could I resize the actual dimension of image?
As an update to a program I had made awhile back, I am trying to auto-resize the image to meet the requirements of my application without having to manually do it elsewhere. I already can adjust the quality/compression for disk storage, but I want to resize the image so I can save the quality of the image.
So how do I resize an image to 1920*1080. (I want to check the image first to make sure that the image is in fact larger then 1080p before I resize it.)
I'd really like the solution to work in a DLL project so that I can move my application from the Windows Forms to the WPF UI.
I am developing a iimage veiwer.
1. i need to resize the form to a suitable size depending upon the heght and width of my image
2. their are two buttons one should always be at the bottom right corner and other always at the top right corner.
3. How do i make the picture fade in.
I'm making a simple little program. It's going to save the image in the clipboard (from pressing Print Screen) to the folder that the .exe is in. My problem is trying to find out how to save the image file with a user-specified name, such as "Image", then adding numbers to it. So it would be like Image_00001, Image_00002, etc. I would like to make the name be specified using a textbox (pretty easy). I know how to get it to save as different image formats and all, and I know how to get it to save as a hardcoded name in a hardcoded location, but that it isn't what I'm aiming for. If you've ever used the screenshot function of Fraps or MSI Afterburner, then that's basically what I'm trying to make here.
I've already searched these forums and did some Googling, but couldn't find anything that I was looking for. Not even a sample program with something like this. I found something in the CodeBank, but it's all the stuff I've already gotten implemented.

View 3 RepliesI have a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.

Set picturebox size to size of image file?

Im sure its easy. Anyone know whats wrong with this?

I currently have a class
Code:
Public Class Customer
Public Property AccountNumber() As String
Public Property PMDue() As String
[code]....
Account Class is initialized as new customer. To save the data from each property in the Account Class, I'm currently looping thru the properties each time Account obtains new data. I tried to simplify the process by the following line...
Code:
CustomerStreamToWrite.WriteLine(Account)
This does not work as written. I figured it would be much faster. It did not write out the property data. It saved "WindowsApplication1.Customer" Not exactly what I wanted. Is there a method to get it to save the properties in a written out style by just using the class name?
