I'm trying to draw a 400x400 px image to a 400x400 form that I made. What I'm doing is:
Graphics.DrawImage Method (Image, 0, 0, 400, 400) 0, 0, 400, 400, ...
But when I run the form, the image seems to stretch slightly upon the y-axis, the x-axis seems to be working correctly.
This was what I was doing before (stretching the old smaller images to fit the size)
... (Image, 0, 0, 264, 231) 0, 0, 400, 400, ...
or something like that. Now that I'm trying to do it the correct way, I can't seem to get it to work properly.
Edit: I wonder if using a simpler verson of Graphics.DrawImage would work?

I want to draw an image onto another image object but use an alphamask specified from another image that is grayscale.
I am drawing an animation manually so don't want to do this pixel by pixel as this would be extremely inefficient.
I need to load a form and for each form background color, put a square on it, my problem is i can't put the square on the orange backcolor right after the first show of form backcolor, and before the timer even start.[code]View 2 Replies View Related

I'm making a front end to dvdauthor.I have a picturebox which holds the menu background. In order to draw a textbutton on the background image I store the image in a hidden picturebox. So the text doesn't get drawn to the visible background.
Dim ctl As Control
For Each c As Control In pbMenu1.Controls
If c.GetType() Is GetType(TextBtn) Then[code]...
This works the first time. But if I hit save again it writes the text to the background image on pbMenu1.

I can't remember exactly if this is possible or not but what I am attempting I would think should theoretically be possible. I know it is possible in WPF but the company I am working for doesn't want to make the transition just yet. Basically what I want is to use a background image on a form for the background and I have a docked control on the right and left. I have set the background on both of these docked controls to transparent however it is showing the back color rather than the background image. I tried, rather than setting the background image property, to override the onpaintbackground and onpaint events and use e.graphics.draw(picture, me.clientrectangle) but it still seems to just pick up the backcolor as the true transparent background so I'm wondering if it's possible to get it to show the background image through the control rather than the backcolor of the form?View 3 Replies View Related
I hoping to find a current and simple way to do this. I'm using VWD Express 2008 and SQL Express 2008.I'm able to get the client's path to the image file using an asp:FileUpload control on the web form.
How do I upload the client's image file and display it in the web form's image control?How do I save it to the sqlserver? The image table is already set up with a "Image" data type column. Can the image be saved to the database as simply as other data types?
i have an assignemnt in my visual basic express 2008 class, were i have to type in an image name, like paris.jpeg,and automatically manipulate the file to be called paris-steg.png. Once this happens i click the manipulate image button and the image should be altered so that paris-steg.png has a message hidden in it. Then i have to decode that message. At this point im having troubel getting the file name to automatically appear as paris-steg.jpeg, and you will proabbly see why with my code. I need to know how to do this. The way i have it, i basiaclly add -steg.png onto the text typed into the text box, this doesnt work when the user types in paris.jpeg as it comes out as paris.jpeg-steg.png. heres the instructiosn and my code
(6) When the text file does not exist, alert the user with a message box and do not do any further processing.
(6) When the image file does not exist, alert the user with a message box and do not do any further processing.
In this program you should read text from a file one character at a time instead of one line at a time. If <tt>sr</tt> is an IO.StreamReader, then <tt>sr.Read()</tt> will return an integer that is the value of the next character in the file. Use <tt>Read</tt> instead of <tt>ReadLine</tt> in this program.You can check whether a file exists by using the code <tt>IO.File.Exists(filename )</tt> . The function will return a Boolean value (True if the file exists but False if not).
You can check whether a string ends with a specified pattern by using the <tt>EndsWidth(pattern )</tt> function. For example, if <tt>s</tt> is a String, then <tt>s.EndsWidth(".txt")</tt> will return a Boolean value (True if <tt>s</tt> ends with the pattern but False otherwise).In a string, <tt>IndexOf(pattern )</tt> gives the first position where the pattern exists, but <tt>LastIndexOf</tt> gives the very last position where the pattern exists.The code <tt>s = Chr(i)</tt> converts the Integer <tt>i</tt> into a character and assigns the character to the string <tt>s</tt> .

I want to draw a line on an image in a picture box. How do I do? The picture box is placed as the only item in a standard form. The following doesn't work:Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint

The corresponding method for the paint event works fine in a panel, but the picture box doesn't seem to support it. What am I doing wrong?

I want to know if there's a faster way to draw images onto a picturebox based on a list of point.
Dim MyPoints as New List(Of Point)
Dim MyBitmap as New Bitmap("C:MyBitmap.PNG")
Now, This code may be a little sloppy, but I just put it together. The image isn't very simple, but it's simple enough. After about 10 images that need to be drawn, it starts to get slow.What would I need to do to ensure it draws the images faster? If I made the image itself smaller would it make it go faster?

Does anyone have any suggestions on the best way of going about modifying a control so that I would have these features?

I assume that this will be an easy one for you guys. I have never dabbled with drawing in VB.NET. I have searched the forum and Google already, but have turned up nothing to help me. Here is my problem. I have an image that is in an image box. I would like to draw a string of text on it, centered vertically and horizontally. Here is what I am using to draw the text.
I know that you can pass a Point array to the DrawImage method of the Graphics object to apply rotation, skewing and flipping, but I'm having trouble figuring out how to calculate the rotation. So far I've got:
Dim radius As Integer = Math.Sqrt((rect.Width / 2) ^ 2 + (rect.Height / 2) ^ 2)
Dim dX As Integer = RadToDeg(Math.Cos(DegToRad(angle))) * radius
Dim dY As Integer = RadToDeg(Math.Tan(DegToRad(angle))) * dX
Dim new_upper_left_corner As New Point(rect.X + (rect.Width 2) - dX, rect.Y + (rect.Height 2) - dY)
This is all just off the top of my head so far, I'm not sure if it's right. How do I calculate the other points on the rectangle, and is there a built-in VB.NET method that's much easier? (Apart from Graphics.RotateTransform, which is slow and also rotates around 0,0.)
I'd like to draw an image (like a bar code) pixel-by-pixel in a Visual Basic .NET WPF Application and ...
show the image in my UI
copy it to the clipboard
save it as a .BMP-File.
It should also be possible to add Paint-like editing features later.What is a good approach? System.Drawing.Bitmap works internally, but the only way I could show it is to convert it to an ImageSource and show it inside an Image control. Is there any better way?
