I have a web app. where I take user information and create a business card image. My question is, How do I convert that jpeg image I have into a pdf?

From whatever image editor you're using for your jpg, you can convert the image into a pdf by going to the Print menu and selecting your pdf maker. I use Adobe Acrobat and highly recommend this, as it creates smaller, clearer files. However, there are also several free pdf creators on the intranet, such as www.primopdf.com, www.cutepdf.com, etc. If you're wanting to create the pdf automatically as part of the application, I'd need more information about what language you're coding your program in.

I'm actually using C# to work with my jpeg image. In fact hear is the code behind so you can get general idea as to what I'm talking about.

I got the source code from someone in Code Project and kind of made my own thing with it, but like I said before the graphics dept. is unable to use the jpg image because when they convert it to cmyk all the brush strokes show up and we can't have that. Any suggestions at this point would be greatly appreciated.

Thanks,

It seems to me that you probably just want to create the PDF ahead of time, seeing as all these paths are hard coded. You also shouldn't be doing this sort of heavy lifting in your presentation layer.

If I can some how raise the DpiX to 300, and the DpiY to 300 then I believe this will all work.

The DPI of a monitor is typically 72 or 96. DPI is actually just rendering metadata, it's got nothing to do with the file itself ( that is, it's independant of resolution )

Ok, so how would I go about fixing the garbage around the text. I've tried playing around with the smoothe antialias option and things of that nature, but have had no new results.

Christian Graus4-Oct-07 12:13

antialiasing is different to noise removal. I don't even know what garbage you're talking about, is it on the jpeg, or just the PDF. DPI will not resolve this either, you need to work out what the noise is, and remove it.

Difference betn Passthrough and Transform Mode of Literal in ASP.Net2.0

4-Oct-07 12:23

When you look at the image after the business card is produced it looks fine. The problem comes when the graphics dept. converts the image to cmyk which causes the Rasterizing of the image, and converting it to cmyk is a must if your going to print the card on the press' that we have. I'm just at a loss right now.

Can any 1 please describe the difference between Transform and Passthrough mode of Literal in ASP.Net 2.0...?

From MSDN Library:

PassThrough
The contents of the control are not modified.

Encode
The contents of the control are converted to an HTML-encoded string.

Transform
Unsupported markup-language elements are removed from the contents of the control. If the Literal control is rendered on a browser that supports HTML or XHTML, the control's contents are not modified.

So, if the server can determine that the browser supports HTML or XHTML, there is no difference.

Formview template controls not accessible?

Richard Jones4-Oct-07 3:08

Richard Jones

On my ASP.NET page, I have a Formview control, which contains several templates (ItemTemplate, etc).

I cannot seem to access any controls in those templates via code.

ie. Double-click a dropdownlist control and it generates a handler for SelectedItemChanged. However, that handler cannot see it's own control, nor any other control in the same template.
Intellisense just says they aren't defined.

I tried drilling down through formview1.ItemTemplate but it doesn't show any controls.

I must be missing something here. Confused | :confused:

How to Use COM Dll in ASP.Net?

Hi I have one COM Dll which needs to be used in my ASP Page. But it is giving Error like this:

Retrieving the COM class factory for component with CLSID {60527433-1464-42EF-A657-3ACE4390AF84} failed due to the following error: 80070005.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {60527433-1464-42EF-A657-3ACE4390AF84} failed due to the following error: 80070005.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true">, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

Can you Help me how to solve this Problem??
