How to know if Successful Conversion

[SIDDARTH]

I am using the tool provided here to convert----->ImageMagick-6.6.2-Q16-windows.zip

I have been able to successfully convert PDF to Tif using .NET

How do i know when a tiff has been sucessfully converted or not.

This is my Command
----------------------------------------------------------------------------------------------------------------------------------
convert -verbose -units PixelsPerInch -density 300x300 -compress Group4 "SOURCE FILE PATH" "DESTINATION FILE PATH"
----------------------------------------------------------------------------------------------------------------------------------

Although i am able to convert PDF to TIF sucesfully i am getting this error.I am able to view it perfectly.
But since i am using Imagemagick in code,apart from the o/p conversion code it is also giving an error message.

Error Message
---------------------------------------------------------------------------------------------------------------------------------
"convert.exe: unable to open image `convert': No such file or directory @ error/blob.c/OpenBlob/2498.convert.exe: no decode delegate for this image format `convert' @ error/constitute.c/ReadImage/532."
---------------------------------------------------------------------------------------------------------------------------------

so i wanted to know when a PDF is converted ,whether its a sucessful conversion or not.Does imagemagick log it in anywhere or any other way to find?
Or the only way is to view & compare the file (PDF & TIF)

Kindly Help me.

try


convert -quiet -regard-warnings input ... output ||
echo "--- FILE DOES NOT EXIST OR IS NOT AN ORDINARY FILE, NOT READABLE OR HAS ZERO SIZE ---"

or whatever message you want to show.

I am still Unable to supress the Error message.(Although I am able to see the output perfectly.)

Is there anyway i can supress it? and

How do i know a sucessfull Conversion.Is it by Manually Comparing or any other way that IM has??

Command Used
----------------------------

convert -quiet -verbose -units PixelsPerInch -density 300x300 -compress Group4 "Source File Path" "Dest File Path"

and

convert -verbose -units PixelsPerInch -density 300x300 -compress Group4 -quiet "Source File Path" "Dest File Path"

----------------------------

Thank you.
Kindly Help

Read the error message:

"convert.exe: unable to open image `convert': No such file or directory @ error/blob.c/OpenBlob/2498.convert.exe: no decode delegate for this image format `convert' @ error/constitute.c/ReadImage/532."

convert.exe is looking for an image file called "convert". So something is wrong with the command line. Post the actual code you are using.

(Cross-posting in Users and Developers forums isn't helpful.)

[SIDDARTH]

Here is the piece of code you asked:

-----------------------------------------

StringBuilder cmd = new StringBuilder();


cmd.Append("convert -verbose -units PixelsPerInch -density 300x300 -compress Group4 ");
cmd.Append("\""+sourcePath + sourceFilename +"\" ");
cmd.Append("\"" + destinationPath + DestinationFilename +"\" ");

System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("ImageMagickPath to convert.exe");
psi.Arguments = cmd.ToString();
psi.UseShellExecute = false;
psi.RedirectStandardOutput = true;
psi.RedirectStandardInput = true;
psi.RedirectStandardError = true;

// Start the process
System.Diagnostics.Process proc = System.Diagnostics.Process.Start(psi);
StreamReader Error = proc.StandardError;
StreamReader sr = proc.StandardOutput;

proc.WaitForExit();

StringBuilder output = new StringBuilder();
StringBuilder ErrorMessage = new StringBuilder();

while (sr.Peek() != -1)
{

output.Append(sr.ReadLine());

}

while (Error.Peek() != -1)
{

ErrorMessage.Append(Error.ReadLine());

}

proc.Close();

----------------------------------------

As already mentioned, On a successful conversion it shows that there is a an error(can see converted images perfectly), although i dont get any when i use the command in my cmd.exe manually.
On Successful conversion i get the ErrorMessage and output.

i) So how do i know whether a successful conversion has happened.
ii) How can i supress the error message
iii) how can we find a conversion has happened sucessfully meaning the tiff is same as pdf.Is it only by manual comparision or any other way in Imagemagick.

It looks as if you are calling convert.exe, giving it the arguments "convert -verbose -units PixelsPerInch" etc. So removing "convert" from the arguments might help.

You can use ImageMagick "compare" to compare two images. It returns a number, where zero means the images are identical.

I tried removing convert already,But it did not help me.

Thanks.

What error message did you get?

[SIDDARTH]

As already said,I have this error message on successful conversion
--------------------------------------------
"convert.exe: unable to open image `convert': No such file or directory @ error/blob.c/OpenBlob/2498.convert.exe: no decode delegate for this image format `convert' @ error/constitute.c/ReadImage/532."
