Thank you very much.
Yes, Magic has right, I use 6.9.0.1 Windows Q8.
I don't understand why Q8 use only 256 and Q16 65K (except a simple 1 byte or 2 bytes representation). For most images Q8 is enough, but the limitation at only 256 connected components is too low.

Can someone explain me why I get "convert.exe: too many objects" and how can be handle it this error. It seems that does not matter the value of " -define connected-components:area-threshold ". By the way, this value represent the minimum number of pixels of rectangle ( width x height ) or what? I ...

Right now I found that and I think is the solution. Thank you very much.

I know that but my intention was to do on a single command.

Thank you, I just saw my mistake:

Now the correct comand is
convert x.jpg -set option:trim_value "%@" -delete 0 y.jpg -crop "%[trim_value]" +repage y1.jpg

The trim value have form WxH+X+Y., but it seems that crop don't want to use it. Another alternatifs?

Hello, can someone help me about how I can use an -set option:variable_name later in same command? Ex: convert x.jpg -trim -set option:trim_value "%@" -delete 0 y.jpg -crop "%[trim_value]" +repage y1.jpg Nothing happen. I verified and the [trim_value] contain the correct value of trim. Thank you.

So "\n" is no more used, right?

Hello, Does anybody know if something changed after 6.8.4 version (wich I used until now)regarding multiple ' -format "%@" -write info: " in a single command? On the older version the output was an array , in newer version 6.9.0 (the only I checked) there is also an array but with only one element ...

I installed the newest version and now is OK. Thank you.

Thank you.So I must install a new version?

Will "-level" applied to a grayscale file make it srgb ?

I have noticed that while aplying "-level" on grayscale files, the result file will be converted to srgb 24bit. Is this normal ?

I am using Q8 6.8.3-10 windows version.

Many thanks.

At http://www.imagemagick.org/Usage/scripts/bg_removal Anthony wrote an script for background removal. There is a more deep explanation about all arguments in this script? Thank you.

I use ImageMagick in command line and send the commands from php. Can anybody tell'me why I can not catch the -verbose -deskew message? (in command line works ) . Also, the info: message works. Thank you.

There is a way to speed up deskew on books scanned images?
