clipping path not applied on a CMYK eps

[kriks]

Hi,

the files :
http://www.pingroom.net/103358_RGB.eps
http://www.pingroom.net/103358_CMYK.eps

we just discovered that with a simple :

Code: Select all

convert 103358_CMYK.eps -colorspace RGB -resize 190x180 103358.png

the background stays white.

but the same with a RGB eps works well (background transparent).

versions:
IM v6.5.1
GS v8.64

thanks for having a look

Clipping requires the -clip option to apply a clipping mask otherwise its ignored.

Try this command to generate an alpha channel for your CMYK EPS image file:

• convert -colorspace RGB 103358_CMYK.eps -resize 190x180 103358.png

thank you, it works like this, but I don't understand the difference.

Why changing the position on -colorspace makes this work ?

Also, we use it with magickwand for php, how to get the same result with it?
