Looks like the same issue


echo "------Script 1----------"
width=$(convert rose: -format "%w" info: | tr -d "\n")
echo "width=${width}"
xx=$((width-1))
echo "xx=${xx}"

Thank you for the help.

No spaces at all.

I did notice a space in the script below
Here is a new pic.

I am using the UNIX line ending built into Notepad++

Here is the image fro the output.

My pc is a Windows 7 32bit

It seems it is returning the correct value of 1 but it is not returned as an int but is returned as a 2 character string



angle=25
# compute crop of input into front and side
sign=$(convert -limit thread 1 xc: -format "%[fx:$angle<0?0:1]" info:)
echo "sign=$sign"
xx=$((sign+1))
echo $xx ...

This is the only one that does work.

angle=25
# compute crop of input into front and side
sign=`echo "$angle>0" | bc`
echo "sign=$sign"
xx=$((sign+1))
echo $xx

I have not tried to recompile the code. I am not to sure how to do this.

Try

angle=25
# compute crop of input into front and side
sign=$(convert xc: -format "%[fx:$angle<0?0:1]" info:)
echo "sign=$sign"
xx=`expr $sign + 1`
echo $xx


sign=1
expr: non-integer argument


or

angle=25
# compute crop of input into front and side
sign=$(convert xc: -format "%[fx:$angle ...

try again with

angle=25
# compute crop of input into front and side
sign=`convert xc: -format "%[fx:$angle<0?0:1]" info:`
echo "sign=$sign"
xx=`expr $sign + 1`
echo $xx



$ ./test
sign=1
expr: non-integer argument



If that fails, then try

angle=25
# compute crop of input into front and side ...

Here is what I get from running the first script.

First run has failed with expr: non-integer argument


testbox@printdemo ~
$ angle=25

testbox@printdemo ~
$ # compute crop of input into front and side
echo "sign=$sign"
xx=`expr $$ sign + 1`

testbox@printdemo ~
sign=`convert xc: -format "%[fx ...

Sorry about that.

Running all of the statements you had above worked great with no issue.

The echo "Length of sign:" ${#sign} is something I did to see the length of the returned value from "sign=`convert xc: -format "%[fx:$angle<0?0:1]" info:`"

It seemed kinda strange that it says the length was ...

So I think I know what the issue is but can not seem to figure out how to resolve it.

Take for example this small code from 3Dcover.


#!/bin/bash

angle=25
# compute crop of input into front and side
sign=`convert xc: -format "%[fx:$angle<0?0:1]" info:`
echo "sign value:" $sign
echo "Length of ...

Seems my issue just could my cygwin setup.

I think I am just missing some packages to be installed.

I did figure out one of the issues is with this line of code

sign=`convert xc: -format "%[fx:$angle<0?0:1]" info:`

it is suppose to return return an integer of 1 in this current context.
