[cairo] Radial gradient

[Zhu, Wei (Clark)]

Hi all,

 

 Cairo can provide the great functionality to generate the pdf file.
Recently, I did some research on how to transfer the pdf file from Cairo
to my preferred one.

 

 See the attachments. The file mstrWeb_363777_EE_Embedded.pdf is
transferred from 7401.R012_Pie_NoDepth.pdf.

 The Cairo output is like the following:

  

However, the transferred result is like the following:

 

 

As you can see, the top of pie in transferred result is whiter than
Cairo output. Meanwhile, the bottom is darker than Cairo output.
Previously, I thought we may have some gradient objects of Cairo output
missing when parsing it. After I checked the source file of
mstrWeb_363777_EE_Embedded.pdf.I found "31 0 obj"( a radial gradient)
doesnot work. Could anyone explain why? I guess this is related to
coordinate system. Any reply will be nice

 

 

Thanks,

Clark
