Re: Chaining Successful Commands

"miff:" is a file format, not a command. The "-" means send it to stdout. You need a corresponding "-" in the next convert to read from stdin.

convert - -resize 128x128! \

Re: PNG2TIFF width transparent background

What version of IM are you using?

When I use
convert test.png test.tif
(version 6.4.5) my result looks like what you want.

Re: Transparent color: black

"identify verbose" tells me the image has a conventional alpha channel. If you effectively want to place this image in front of a white background, so the white shows through the transparent areas, try: convert newsletter.png -background white -flatten newsWhite.png [Edited: added "-" in front of "f...

Re: Transparent color: black

Is this for 256-pallette Gif?

The "-transparent-color" option is probably what you need.

Re: convert to ADOBE rgb profile

It probably means your version of mogrify can't read or write jpg files. Try: mogrify -list format It should have a ouple of lines like: JPEG* JPEG rw- Joint Photographic Experts Group JFIF format (62) JPG* JPEG rw- Joint Photographic Experts Group JFIF format What version are you running?

Re: How to save the DIFFERENCES between two images ?

When I run the convert command given by fmw42, I get a different image to image12diff.png on Google. (Personally, I'd put a +repage after the +trim. But that isn't relevant to transparency.) This is using an old IM: 6.4.5 Q16. The image I get has a transparent background, which I would expect. When ...

Building under Ubuntu

No questions; just some notes might might save someone some grief. I installed Linux 9.04 from the current version of ArtistX. Then I downloaded IM from ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz, and compiled from source, as directed by http://www.imagemagick.org/script/install-so...

Re: help with script bg_removal

About the best I can get with bg_removal is: ./bg_removal img_0092.jpg 'RGB(37,188,111)' 18 19 img_0002_C.jpg These parameters cut slightly into the sock and fur, and leaves a little of the green surround. You can tweak the "18" to adjust your compromise. I got the colour by using Gimp to get an ave...

Re: help with script bg_removal

I would certainly use an image closer to what the camera photographed (not shrunk, etc). Method 1: Simply and crudely turn the green white: convert img_0092.jpg -fx "hue<0.25||hue>0.50?u:white" img_0092_a.png This gives jaggies, and we have lost the white sock and fur, which have picked up the refle...

The links don't work. Perhaps you didn't tell GoogleDocs that anyone could have access.

Re: Auto-detect optimal image output format, How to

I suggest that subjective "quality" is hard to determine in software, including ImageMagick.

You might find that creating both PNG and JPG versions, with suitable "-quality" settings, then choosing the smallest of the two, gets you somewhere near.
