Converting Images under Windows XP 32bit

[r0bb3n]

Hi,

when I try to crop an image with this code:

        String myPath="C:\\Programs\\ImageMagick-6.3.9-Q16";
        ProcessStarter.setGlobalSearchPath(myPath);
        IMOperation op = new IMOperation();
        op.addImage("c:/tile_small_street.png");
        op.crop(100,50,5,15);
        op.addImage("c:/tile_small_street_out.png");

        ConvertCmd cmd = new ConvertCmd();
        cmd.createScript("convert_batch",op);
        cmd.run(op);

I get the following Exception

19:11:25,467  org.im4java.core.CommandException: java.io.FileNotFoundException: convert 
org.im4java.core.CommandException: java.io.FileNotFoundException: convert
    at org.im4java.core.ImageCommand.run(ImageCommand.java:215)

The Batch looks like this:

@echo off
REM -------------------------------------------------------
REM  Cmd-script autogenerated by im4java
REM  at Thu Sep 01 19:11:25 CEST 2011
REM -------------------------------------------------------
set PATH=C:\Programs\ImageMagick-6.3.9-Q16;%PATH%
convert ^
  "c:/tile_small_street.png" ^
  -crop "100x50+5+15" "c:/tile_small_street_out.png"

This batch is running without errors and the image looks correct.

Also when trying your sample code Test1 I also get errors but they look different:

 1. Testing convert ...

    ... 3 more

I hope you can help me, because I need it for work.

Thanks in advance.

Hi r0bb3n,

String myPath="C:\\Programs\\ImageMagick-6.3.9-Q16"; ProcessStarter.setGlobalSearchPath(myPath); /quote]

im4java will search for convert.exe, convert.cmd and convert.bat in C:\Programs\…. Please verify, that your convert-executable is exactly in the directory which you pass to setGlobalSearchPath.

The batch-file might work because you probably have the convert-executable somewhere else in your path.

The test doesn't work because the tests don't set the searchpath internally. To use the tests, you should set IM4JAVA_TOOLPATH. The program fails because it uses a Windows-utility also called convert (but which expects different parameters).
