View 1 Replieswhat is the height of a regular PDF page in pixels?
i heard it was something like this:
Dim pgSize As New iTextSharp.text.Rectangle(595, 792)
but i am adding an image that takes up maybe half the height, and even though pgSize looks like a full page and the image takes up only half of it, i am getting a height of like 619 for the image? i do not know if it is in the same units?
I 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)

I save my images into my SQL Server Database with ASP.NET(2.0).
(imageData -> image) (imageType -> varchar) (imageLength -> bigint)
Thus the imageData will be "Binary data" and the imageType will be like "image/gif" and the imageLength will be like "6458".......
Is it possible to get the image HEIGHT and WIDTH from my VB.NET code inside my ASP.NET? I want to make my picture box on my web form the size of the actual image that is saved in my database.
I drew an image in a picturebox with the image height as picturebox height and image width as picturebox width. The image is placed somewhere on the center of the picturebox. My intention is to scale the image to fit to the picturebox.
View 2 RepliesI 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?
in vb.net is it possible to get the coordinates of an image like if i do a
document.add (jpeg_image)
x_coordinate = jpeg_image.xcoordinate???????
I'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?

View 1 RepliesI 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.
Is there any way that I can add a project resource image to my PDF?
I'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.

Below is some code. Note the comment "SOULD BE -1" If I make it -1 I get the message that I'm trying to write into protected memory.
Not on all images but a few that I tested.It appears that inBitmap.Height points to non-image data.
1)Can you tell me what is wrong and how to fix it?
2)Or how to test so I don't crash.

View 4 RepliesI am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF

Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.
