.net - Controlling Image Resolution When Converting A PNG Image Into A PDF Using ITextSharp?
Aug 10, 2010I have created a PNG image that is 200 DPI, and perfectly sized for a landscape A4 page size. I needed to convert this to a PDF document, so I've used the iTextSharp library with the code below.This all works, however the image quality has degraded.
Public Sub ConvertPNGtoPDF(ByVal inputFile As String, ByVal outputFile As String)
Using fs As New FileStream(outputFile, FileMode.Create, FileAccess.ReadWrite, FileShare.None)
Dim document As New Document(PageSize.A4.Rotate, 0, 0, 0, 0)

.net - ITextSharp Overlay Image?
Mar 15, 2011I have an instance where I have a logo image as part of some artwork..If a user uploads a new logo I have a form field which is larger than the default logo.I then use that form field to position the new image.
The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo..
what I have done is:foreach (var imageField in imageReplacements)
{
fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null);
fields.RegenerateField(imageField.Key);
PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber);
float[] logoArea = fields.GetFieldPositions(imageField.Key);
[Code]...
The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.is there a way to set a stacking order on layers?

Extract An Image From A Pdf File Using ITextSharp?
Jul 9, 2010I'm currently trying to extract an image from a pdf file using iTextSharp.
The pdf is made from a scanner: it has a single page that contains one big image.
When looking at the file I find the following:
<< /Type /XObject /Subtype /Image /Name /Obj3 /Width 2480 /Height 3507 /ColorSpace /DeviceGray /BlackIs1 true /BitsPerComponent 1 /Length 5 0 R /Filter /CCITTFaxDecode /DecodeParms << /K -1 /Columns 2480 >> >> stream
[Code].....
But, that doesn't work as I get one big black tiff file with different shades of gray on top.
Does anyone know a way how I can decode those CCITTFaxDecode images?

Aug 3, 2010I have iTextSharp creating a pdf for me in VB.net. Everything was working famously, except now I want to embed an image. I tried this:
Dim test = My.Resources.MyImage
Dim logo = Image.GetInstance(test)
This an error though:
'GetInstance' cannot be called with these arguments
It appears as though it expects a path, and is getting a System.Drawing.Bitmap type.

ITextSharp Renders Image With Poor Quality In PDF?
Mar 26, 2010I'm using iTextSharp to print a PDF document. Everything goes ok until I have to print the company logo in it. First I noticed that the logo had poor quality, but after testing with several images, I realize that was the iTextSharp rendering it poorly.The test I did to say this was to print the PDF using my code and then edit the document with Acrobat 8.0 and I drew an image. Then printed the two documents and saw the noticeable difference.My question is that if anyone know if this can be due to a scaling problem where I'm failing to tell iTextSharp how it must render the image or is an iTextSharp limitation.

Determine An Image's Screen Coordinates?
May 11, 2012I have an image resembling a chessboard inside a picturebox displayed on the screen at runtime. I am using Visual Basic in Visual Studio 2008. I need to determine when a user clicks on a particular part of the image. I am able to do this without a problem when debugging on my computer, where I can experiment with trial-and-error clicking to get the screen coordinates of the portion of the image of interest. Everything changes, however, when the program is run on a screen with a different resolution and coordinates.
I can easily get the coordinates for the picturebox that contains the image using PointToScreen. However, there seems to be no such property for the image within the picturebox, which is what I need.

View 1 RepliesHow To Emulate Image Button Click With X And Y Coordinates
Nov 29, 2010I'm trying to automate using a remote ASP.NET website using the .NET WebBrowser control to simulate user input. I'm trying to call InvokeMember("click") on an image button on the remote site but it doesn't appear to be working and I suspect it is because the X,Y click coordinates that are submitted are both 0,0 (rather than representing real click coordinates). Is there any way I can programmatically set the submitted x,y coordinates to emulate a real click? (BTW I know I'm selecting the correct HTML element on the page so I've exhausted all other possible reasons why this is not working other than the x,y coords!)
View 1 RepliesSet Coordinates For Each Beam At Intervals Of 610 Then Write That Coordinates System To A Text Based *.SCR File
Dec 2, 2010I am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file
