But it creates images from the html with images of cmyk colorspaced . I checked the resulted image and it is also CMYK colorspaced. I used a cymk colorspaced image(size of 7 mb) but the resulted image size is 700kb.

check this is issue https://code.google.com/p/wkhtmltopdf/issues/detail?id=379 latest comment will give you solution

The new official wkhtmltopdf issue for this is wkhtmltopdf/wkhtmltopdf#39 - as you can see, it's closed with an UpstreamChangeNeeded label. This will most likely need to be supported in WebKit and then QT before it can be supported by wkhtmltopdf and then snappy et al.

hi
Any patch for this issue

from knpsnappybundle.

@akshayodesk unfortunately, I am sorry to say that no, there is no resolution in wkhtmltopdf itself because it is dependent on QT CMYK patch. I suggest to use RGB meanwhile.

@akovalyov i have some html with embedded cmyk images
I need to convert it to pdf cmyk .
How should i proceed

I am a developer and ready to modify the qt webkit source code if required.

Thanks

@akshayodesk as stated, I suggest you to convert your images if possible.
You can also try http://stackoverflow.com/questions/12819716/wkhtmltopdf-how-do-i-increase-the-pdf-quality-of-a-document-generated/12843619#12843619 solution and use --enable-smart-shrinking option in Snappy.
All the source you need you can find in https://github.com/wkhtmltopdf.

Bon courage.
