Color of TIFF image

My original image color is yellow but it turns to be orange when I put it in PDF. Please help me. I try to use img.ImageInfo.TiffFrame = -1 but it doesn't work.

Dear lnhuy,

Thank you for considering Aspose.

Can you please send me the image and let me test it?

Dear lnhuy,

Thank you for considering Aspose.

I think this is a special TIFF format that is not supported properly by Aspose.Pdf. I opened this image with windows image viewer and the color is orange as shown in the attached snap image. I also tried open the image with Acdsee and it displayed correct. When I saved the image to another TIFF file with Acdsee and the generate pdf, it works well. So I suggest that you resave your image with some advanced image tool such as Acdsee.
