Empty object 15 in pdf (pdf.c)

[baskote]

Hi,

converting a jpg to pdf is creating an empty pdf object, which creates an error on acrobat.
The problem happens in pdf.c (ImageMagick 6.3.4), there will be checked for (image->matte != MagickFalse) and only then content will be written. So i patched it and moved the output of the object start and end inside of the if, so it will be printed only if the content is printed too.

-------
14 0 obj
13575
endobj
15 0 obj
endobj
16 0 obj
13575

Here is the patch for ImageMagick 6.3.4

Can you please give us feedback if this will be applied ?

We applied your patch to ImageMagick 6.3.4-9 Beta available sometime tommorrow. Thanks.

I have the same problem in converting JPGs into a single PDF file.

I've just downloaded ImageMagick 6.3.4-9 and it does not appear to have solved the problem.

i checked the version 6.3.4-9 and the fix is included and worked with our jpg images. Are you able to post the examples somewhere and provide more informations about the error you detected and how you have seen the error ?

I am having the same problem as this. Does anyone have an answer? I can provide a sample file.
