Problem during conversion of EPS file to EPS

[rif_k]

Redhat Linux 6.5 x64
ghost script; 8.71
ImageMagick-6.8.6-Q16
ghost script; 9.18
ImageMagick-6.9.2-Q16

I want to decrease file size of "EPS fileA" by resizing.
So, I converted "EPS file A" to "EPS fileB".
But the problem as follows has occurred during its process.


EPS information is correct when I open "EPS fileA"(4840x3774 Resolution:350) with Photoshop CS6 and Illustrator CS6.
Dialog doesn't appear.

I converted "EPS fileA" to "EPS fileB" by these commands.

convert -strip -resize 4840x3774 -density 350x350 "EPS fileA".eps
"EPS fileB".eps
convert -strip -resize 4840x3774 -density 350x350 -colorspace cmyk
"EPS fileA".eps "EPS fileB".eps
convert -strip -resize 4840x3774 -density 350x350 -colorspace Gray
"EPS fileA".eps "EPS fileB".eps
convert -strip -resize 4840x3774 -density 350x350 -colorspace sRGB
"EPS fileA".eps "EPS fileB".eps
convert -strip -resize 4840x3774 -density 350x350 "EPS fileA".eps.eps eps2:
"EPS fileB".eps

Photoshop shows me this rasterize dialog when I open converted file "EPS fileB"


This dialog's resolution value shows what I input at last time.
I guess Resolution:350 info before conversion had been already lost.

issue list
1)Lost Resolution and EPS profile values
2)Increasing file sizes (File A: 7.3MB to File B:108 MB)

How can I fix this issue?
Should I use other command option?

What does fileA.eps contain? Raster data or vector (pixel) data? IM is a raster graphics processor. If your EPS contains vector data, IM will rasterise it, then save it to the new eps file as raster data. That would explain the massive increase in MB.

thank you for reply.

File A is vector data.
I understood EPS convertion flow.

I got a new question when I read this topic few minutes ago.
viewtopic.php?t=8508

Can I output EPS file containing vector data with ImageMagick and GS now?

Can I output EPS file containing vector data with ImageMagick ...

As I said, IM first rasterises the vector data, which turns it into pixels. It will write these pixels in the EPS, not vector data.

Perhaps some "-compress" option will reduce the size of the output. But it won't change pixel data back into vectors.

I see...
Thank you so much.

But my case needs to get raster data.
I understood this case is not useful for me, I try to find other solution.

Thaks a lot!
