ITextSharp - How To Input Image (PNG) From Project Resource
Aug 3, 2010
I 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 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)
[code]....

I 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?

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?

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.

If I have say a wav file as a resource in a form, is there a way that I can extract it when the program is run and set it as say... the windows logon sound? Or perhaps an image and set it as the wallpaper? Or does it have to be an external file that the form would have to handle?

In a VB project I can add a resource via the project properties resources tab, or I can right-click the project in the solution explorer, click add, then click add existing item. What are the differences?If I want to add a DLL file and include it as an embedded resource, do I have to add the file via both methods? Only one?

Im in a win.form app. in .Net 2008 I have a lot of Icons that I want to display on a (TouchScreen enviroment) button The icons are in 8,16; 32 bit in the sizes 16X16 ; 32X32 ; 48X48
The buttons are large enough, they have a dimension of 252X132.The images are loaded via the Button propertie : Image. This has allso a size propertie, but is disabled. And I can see its loading the 32X32 32bpp format But I want the 48X48 size on there. Does some 1 knows how to get those sizes op the button.
I know its possible via a imagelist but why have a resource if you cant use it??

I'm pretty sure this is something super easy, but how do i access a resource that is in a separate project using the expression syntax?I thought it would be like so:
<%$ Resources:SomeNamespace.Resources.Web, PleaseSelectAnImage %>
where SomeNamespace.Resources is the project that the resources are located in.
i normally just do <%= SomeNamespace.Resources.Web.PleaseSelectAnImage%> but i need to have this inside a control. <kw:SlickUpload ID="SlickUpload1" runat="server"
ValidExtensions=".png, .gif, .jpg"
InvalidExtensionMessage="<%$ Resources:SomeNamespace.Resources.Resources.Web, PleaseSelectAnImage %>" >
so when i just do what i normally do, it puts <%= SomeNamespace.Resources.Web.PleaseSelectAnImage%>" literally.my project name is SomeNamespace.Resources. the resource file name is Web. and the key is PleaseSelectAnImage.

I use WPF and my program has images in a DLL resource file. I have this well working way to read in images from disk:
Private Function GetImageFromFile(ByVal fileName As String) As BitmapImage
Dim buffer As Byte() = IO.File.ReadAllBytes(fileName)
Dim memoryStream As New IO.MemoryStream(buffer)
[Code]....
Now, how can I get images in this MemoryStream-way from a DLL resource?
The basic problem: If I use simply the "bitmap.UriSource = whatever uri" way and load many images in sequence like an animation it builds up the memory. I tried with the above memorystream way and it worked perfectly fine, but then I store my images in a dll and I don't know how to do this trick. If anybody knows how to read many images from a managed dll without building up the memory

I have a Windows project in Visual Studio 2010 in which I store all images in the project's resource file that Visual Studio created for me. However, it's getting cluttered and I'd like to separate images into multiple resource files if possible. I created a new resource file, but Visual Studio doesn't recognize it when I go to the form designer and try to change an image. The only file that comes up under the Project resource files available are MyProjectResources.resx. The one that I just created isn't there.

So there's lots of examples of how to do this if your text file happens to be in XML format. However, my text file is not in XML format and as it contains over 172,000 rows I'm not that keen on adapting it (it's a dictionary)! The text file has been included in the project as a resource.
So far I've got a DataGridView (could use a DataRepeater if easier?), a BindingSource and a DataSet.
The DataSet has a DataTable already defined in the designer with one column.I've managed to load the text file into a String and then create a StringReader based on that String variable, however I cannot find anyway of loading those strings into the DataTable.
Dim listWords As String = My.Resources.WordList Dim strReader As New System.IO.StringReader(listWords)
'What now???There are some examples of using OleDb functionality but all assume you're loading from a text file residing somewhere in the filesystem, not a project resource.(I'm also assuming that on building the application the resources get embedded (somewhere) rather than being accessed from [AppDir]/Resources/[filename] ??)

A DLL file contains some images inside PNG resource type.
I can view the PNG images in softwares like Resource Hacker, Anolis Resourcer & Resource Tuner. Check this screenshot of Anolis Resourcer for more details:
how do I get the PNG image no. 5220 from the DLL file and put it inside a PictureBox? I don't think APIs like LoadImage or LoadBitmap will work.

I cannot seem to get my image resources to load into PictureBox1.I can see all the images I added as resources in the solution explorer.They are a series of PNG files with names associated with countries.I am at the beginning stages of randomly changing the image that is displayed in PictureBox1, but I cannot even get the first image to load.Here is my code so far. When I click on Button2 I can see that my array returns a random country, but no image loads.I even tried typing in several of the countries names as well as the country name followed by png (e.g. chine.png) and again no image loads.
Public Class Form1
Dim randomObject As New Random()
Dim Flags() As String = {"australia", "brazil", "china", "italy", "russia", "south africa", "spain"}[code]......
