What is difference between geometry and base geometry in verbose info for an EPS file?

Image: test1.eps
Format: EPT (Encapsulated PostScript with TIFF preview)
Class: DirectClass

Geometry: 806x859+0+0
Base geometry: 3358x3580

Resolution: 300x300
Print size: 2.68667x2.86333
Units: PixelsPerInch
Colorspace: CMYK
Type: ColorSeparation


When I convert to PNG the result is equivalent to the base geometry. So what is the point of the geometry which is so different.

It appears that the Geometry is the equivalent size when using the default density of 72. Is that a correct interpretation?

3580*72/300=859

The base geometry is the width and height of the image when it is first read-- before any operations are performed on the image.

Then why does the image show a geometry that is different from the base geometry when read and nothing is done to it. It comes from identify -verbose

We would need to inspect the image before we can comment. Where can we download test1.pdf?

Inspect test1.eps. The page width/height is extracted from this line:

I do not see that line from identify -verbose test1.eps, but I do see a line

Page geometry: 806x859+0+0

which corresponds to the clip data line in the svg file

<svg xmlns="http://www.w3.org/2000/svg" width="806" height="859">

Both these correspond to the geometry.

As opposed to the base geometry which is 3358x3580.

So I suppose the geometry corresponds to the clip information and the base geometry is the original un-clipped size.
