Asp.net - Image Appearing Larger Than Actual Size In PDF?
Nov 17, 2011
I have the following barcode image:
I'm using the following iTextSharp VB.NET script to generate a PDF document containing this barcode:
Dim pdfDocument As iTextSharp.text.Document = Nothing
Dim filename As String = HttpContext.Current.Server.MapPath("barcode.pdf")
pdfDocument = New iTextSharp.text.Document()
[Code]....
When this PDF is generated, however, the image is appearing larger than expected, and is distorted:
I can't see anywhere where I'm setting the image to be a specific size, so why would it distort like this? And how can I prevent it?
It's crucial that this image remains the size it is intended to be so that it can be read by barcode scanners.

As you'll can see the first image is the size of (1024*768) and it is correctly displayed in the picturebox and in the second case the image size is (1600*900) and it is displayed to half of the picturebox and the remaining is missing .So No I would like to fir that image in the picturebox no matter what the size is and even though it is greater than the size of the picturebox.I need to scale that Image.So how do I do that?And one more thing is that I need to resize the picturebox automatically when the image loads to it just as we see in the lightbox effect..url...

I am trying to get a small bitmap from a larger image. something like
Dim bmp As New Bitmap(PictureBox2.Image)
However this just gets the entire picture not just a portion of it, I would like to do something like this where I can specify the starting and stoping points
Dim bmp As New Bitmap(PictureBox2.Image, StartX, StartY, EndX, EndY)
I would also like to take these smaller images and paste them into a single larger image. Is there any way to paste it in starting a a certain point. Such as
paste bmp into Picture1 (StartX, StartY)

I have a requirement to do a quick print of a form. This form has all kinds of controls and data. The problem is that the form is too wide and the left side of the form gets cut off when printing... when I use the PrintForm power pack control.I tried using bitBlt and it did the same thing. I could not see how to shrink the image to fit.
Also when getting to the Printer Dialog, the printer option to "Shrink to Fit" did not work either.How can I shrink the image? I do not know much about printing and thus printing each control is foreign to me.

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 form which contains an Image control. What I am trying to do is find a way to adjust an image according to the size of the control and have the image look normal no matter how I adjust the Image control. I want the actual image to fill the Image control completely and not loose any integrity.

I'm writing a Cleint/Host program that sends a image over tcp (from printscreen, not a file) to the host. Everything seems to work fine and the image is transmitted and displayed in a picturebox plus saved to a folder. The problem is when the printscreen is bigger than 176040 B. First the limit was 128000B but after setting the sendbuffersize and recivebuffersize to 1000kb the limit is 176040 B. Could it be a limit in the tcp protocol?
Here's the client code

I have a picturebox with a tiled background image (plane white bitmap), and an "image" resource centered in the middle of it, I would like to chance the size of this centered image within the picturebox.
I tried:
picScaledRepresentation.SizeMode = PictureBoxSizeMode.CenterImage
picScaledRepresentation.Size = New Size(Width, Height)
But this just changed the the size of the whole picturebox, rather than the image within it.

I'm currently working on a school project. And a part of the program is to 'change' the images. All images added are BMP-files. But the output has to be JPEG. Now there are 2 other problems:
- The width of the image should be between (70-165 ) Pixel and the height between (65-185 )Pixel
- The filesize of the image should be between (3-4 KB)
I know how to change the width/height, but it's hard to make the filesize between 3-4 KB.

My users uploads a picture and the picture get saved into my SQl Server Database.My users view the picture on the page in a normal Image WebControl with size 150px by 150px - example can be found[url]...
If the user uploads a picture of 300px by 200px the image will look funny in my static 150px by 150px Image box. Any idea how i can display the Image so it wont be fuzzy?
Also, how can a have some form of pop-up that will appear on the screen, showing the actual size of the picture from the database when the user clicks on the 150px by 150px Image.
Note: I dont want the Image static size to increase as this will totally mess up my page layout and look. It must be some form of pop-up or something. Something i have seen before i think was really cool. User clicked on the small image and then a pop-up appeared in the middle of the screen with the actual size of the picure and everything ells on the page was disabled until the user clicked on the close button.

I can not seem to figure out how to change the size of a photo being put into a picture box.I need the photos that are placed in the picture box to come in their original size....I have 4 different pictures in an ImageList and depending on what a Text box from a different form says, one of the photos will be displayed in a picturebox when the form is loaded. Right now all the images show up very blurry and in the predetermined size in the imagelist. Here is my code:[code...]
As you can see I figured out how to autosize the PictureBox (candypic) to the size of the image coming in....just cant get the image to come in as the right size.....
When I created the imagelist all the photos have a default size of 16, 16 when entered into the list.....I see in the imagelist properties how to adjust the image size but it groups them together as one.
