Puzzler! In ImageMagick 6.5.8-9 I get

identify -format "%x - %[resolution.x] - %[fx:resolution.x]" SeedImage_9.jpg
72 PixelsPerInch - - 72

i.e. it doesn't report the middle one.

I can just use the fx option. But is this a bug?

identify -format "%x" SeedImage_9.jpg produces 72 PixelsPerInch
identify -format "[resolution.x]" SeedImage_9.jpg produces empty line.


What gives? I just want the dpi without having to parse out the unit text.

hi,

I want to set the colorspace as CMYK prior to a long series of (independent) convert commands in a bash script, then return it to sRGB when the script is done. How do I do that?

That's odd.

1) the EPS that bookland generates is 72 x 72.

2) the result of

convert -units "PixelsPerInch" -density 300 -colorspace CMYK images/$uuid/print/$userprovidedprintISBN.eps -density 300 images/$uuid/print/$userprovidedprintISBN.png

is an image that is

Hi

Must be doing something simple wrong...

I am using Judah Milgram's bookland program to create an EPS bar code to lay on a book cover.

I want to convert the resulting ISBN.eps file to a PNG. The barcode object on the book cover is supposed to be 1.75 x 0 ...

How can I create the spine for a book with the title left justified, some space, followed by the publisher name right justified? I understand how to rotate, the problem I am having is that I don't know how to make the title gravity west and the publisher name gravity right at the same time.
