error with simple convert from pdf to jpg or png

[arpeggio]

Hi and thank you for reading my 1st q.
(from spending 2 days on this & seeing how many other people are having trouble too, i can tell it probably wont be my last! )
anyway here is my problem: in the command prompt just to test everything is working:

converting IMAGE => IMAGE: works just fine:
eg: convert test.jpg test.png
result is fantastic! what an awesome prgm.

but PDF => IMAGE (jpg, png, etc) gives an error:
eg: convert "onepage.pdf" onepage.png
result:
convert.exe: unable to open image `onepage.pdf': No such file or directory @ error/blob.c/OpenBlob/2641.
convert.exe: no images defined `onepage.png' @ error/convert.c/ConvertImageCommand/3066.


Some background info:
My system is an oldy but a goody: MS XP with service Pack 3
I installed ghostscript (gs906w32) in my D:/XAMPP directory before installing ImageMagick-6.8.1-9-Q16-x86-dll in D:/XAMPP
earlier today and yesterday i tried other combinations because i thought it could be the age of my system but it gave me the same problem. I also tried directly installing both under D:/ but still same problem that it cant find the file.
The reason i installed both in the XAMPP directory is because ultimately my aim is to use PHP to automatically convert pdfs and just to keep everything together.

Can someone pls tell me what to try next? I really hope someone can help me. This is really troublesome and costing so much time.

Thank you and best regards,

What happens when you try the following two commands?

Code: Select all

identify onepage.pdf

Code: Select all

dir onepage.pdf

Hi snibgo and thank you very much for your questions.

i received the following results:

identify onepage.pdf
identify.exe: unable to open image `onepage.pdf': No such file or directory @ er
ror/blob.c/OpenBlob/2641.

dir onepage.pdf
Volume in drive C has no label.
Volume Serial Number is 9C0E-F3D3

Directory of C:\Documents and Settings\UserA

File Not Found

If i do this with just plain image files (eg: jpg, png, etc) i get the following:
identify castle_logo.png
castle_logo.png PNG 100x75 100x75+0+0 8-bit sRGB 13.9KB 0.016u 0:00.014

dir castle_logo.png
Volume in drive C has no label.
Volume Serial Number is 9C0E-F3D3

Directory of C:\Documents and Settings\UserA

1 File(s) 13,916 bytes
0 Dir(s) 2,805,780,480 bytes free

Incidently all the files i am trying to convert including onepage.pdf are directly in the UserA directory.

Do the above results tell u much? I dearly hope so!!
Thank you so much and with best regards,

This tells us the file isn't there. You need to find onepage.pdf and copy it to the directory.

Well i feel like a complete idiot but you are right snibgo. Thank you.
I could've sworn it was there last night! but it works like a dream now (though only on single page pdfs for the moment)
still need to play around with it to see if i can render multiple page pdfs.
thanks so much for your constructive questions.
awesome program.

best regards

to render multiple page pdf files that do not have transparency, I believe you have to switch the sDEVICE to pnmraw from pngalpha in the delegates.xml file


<delegate decode="ps:alpha" stealth="True" command=""gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pnmraw" -dTextAlphaBits=%u -dGraphicsAlphaBits=%u "-r%s" %s "-sOutputFile=%s" "-f%s" "-f%s""/>

IM uses ghostscript and as I understand it, it cannot handle both multiple page pdf files and transparency at the same time. You have to pick one or the other.

But if some one else knows otherwise, I will defer to them.
