Try this command:

• convert -colorspace sRGB TEST\ AI.ai test.png

[fmw42]

I renamed your file to TEST_AI.png to avoid the space in the filename and the following works fine for me on IM 6.9.2.8 Q16 Mac OSX with Ghostscript 9.10

Code: Select all

convert -colorspace sRGB TEST_AI.ai TEST_AI.png

What is your version of Ghostscript?

gs --version


This also works by quoting the filename.

Code: Select all

convert -colorspace sRGB "TEST AI.ai" "TEST AI.png"

Note your file is CMYK and should be converted to sRGB as above or with profiles, since PNG does not support CMYK

thanks it work for me
should i use same for PSD file?

[fmw42]

Yes, if the PSD file is CMYK, then use the same -colorspace sRGB before reading in the PSD file.

THANKS

Actually if the ai or pdf file is already sRGB, it should not hurt to add colorspace sRGB before reading in the file. Same for any vector format file.
