How to detect a CMYK image in a pdf file?

[Jeethu]

I am trying to find the colorspace of an image in a pdf file using spire pdf.

I tried with a pdf file with a CMYK image created from Photoshop. But always I am getting

RGB colorspace for the image.

Image[] images = doc.Pages[0].ExtractImages();
Image image=images[0];

I tried the following :

1. Checked image.Flags
2. Checked image.PixelFormat

Both didn’t work for me. Is there any other way to find whether the image is CMYK?

Hello,

Sorry to keep you waiting.
The new version of Spire.Pdf( Spire.PDF Pack Version:3.5 ) added a new method to get the CMYK image from PDF.

Code: Select all

Page.ExtracImage(bool processImage).//false returns original image in PDF.

Please download it via link below and have a try.
