Write a code snap to convert .tif to PDF file format.

Hi,

I have millions of .tif image files in D: drive of my computer. Those files are separeted by Year folders(e.g. 1990, 1991, 1992.....) and each year folders have those tif files.

so the local path :

D:\publications\1901\...tif

Now, inside the year folder(1901), the .tif files have different page for the same date(e.g.1901-09-21-p01.tif,1901-09-21-p02.tif,1901-09-21-p03.tif,1901-09-21-p04.tif,1901-09-21-p05.tif....)

I have to write a .net code so that it reads and open the year folder and reads the tif files inside it and change the multiple .tif files(which have same data) to single pdf file.

e.g. 1901-09-21-p01.tif,1901-09-21-p02.tif,1901-09-21-p03.tif,1901-09-21-p04.tif,1901-09-21-p05.tif............to 1901-09-21.pdf

1901-09-22-p01.tif,1901-09-22-p02.tif,1901-09-22-p03.tif,1901-09-22-p04.tif,1901-09-22-p05.tif............to 1901-09-22.pdf

......................

and save to local drive. When finish for 1901 and read for 1902 year folder and convert the tif files of it to pdf file....

so, it should do for all the year folders publication images.

Anyone has idea ??

Thanks in Advance.

Re: Write a code snap to convert .tif to PDF file format.

thanks, chintanpshah for your reply.

How can I read the same date files and convert only those to single pdf and again read another same date tiff files and convert to pdf and so on...

How can I do this automatic, so I can give only the local physical path for the input and output ?

Thanks

Re: Write a code snap to convert .tif to PDF file format.

Thanks, Chintanpshah for your useful post.

The first link is the easy one to implement and I have small problem here:

in this line, he specified the single tif files (

System.Drawing.

Bitmap bm = new System.Drawing.Bitmap(Server.MapPath("~/App_Data/source.tif"))

how can I specify multiple tif files to convert to single pdf.

I did this

/app_code/*.tif but this didn't work.

Thanks

Re: Write a code snap to convert .tif to PDF file format.

TIFF to PDF can be done using iTextSharp PDF open C# Library (itextsharp.dll).

i recommend you to do easily this bulk transformation task using SQL Server Integration Services package.

1. Include FileSystem Task and read the TIFF image paths.
2. Include ForEach loop task and loop through each of source image TIFF image path.
3. Create a CONSOLE application project with following code snippet.

4. Include a EXECUTE process Task and point to the CONSOLE application project.

That's it... you are done with all WORKFLOWs with out of the box SSIS ready made toolsets.

Refer the following CONSOLE Application EXE file in SSIS ProcessTask and pass variables (TIF path and ToBePDF fileNamepath) as parameters to the console application.

Following is the code snippet with CONSOLE application taking two commandline arguments...

Arg[0] --> SOURCE TIFF image path and
Arg[1] --> Destination PDF document path

Hi Bharath,

The code snap you posted works well for A4 size tiff files but not for other tiff files with different dimensions. Please let me know if you have any other code for this.

Thanks!
