Bug ID: 112418
Summary: Calling ImageMagick COM object from macro with more
than two parameters results in exception
Product: LibreOffice
Version: 3.5.0 release
Hardware: All
OS: All
Status: UNCONFIRMED
Keywords: notBibisectable, regression
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Download and install ImageMagick from [1]. There are lots of different
versions, for 32-bit LibreOffice ImageMagick-7.0.7-2-Q16-x86-dll.exe should be
good.
During installation make sure check box 'Install ImageMagick OLE Control' etc.
is checked. Finally, restart your computer.
Start Writer, open the macro editor via Tools -> Macros -> Edit Macros.
The following macro code uses ImageMagick to flip the image in the first
parameter horizontally, saving the result into the file in the last parameter
(substitute valid file names).
Run the macro:
Sub Main
Set img = CreateObject("ImageMagickObject.MagickImage.1")
r = img.Convert("c:\input.png", "-flop", "c:\output.png")
End Sub
There is the following error:
"BASIC runtime error.
An exception occurred
Type: com.sun.star.lang.IllegalArgumentException
Message: [automation bridge]UnoConversionUtilities<T>::createUnoSequenceWrapper
The any does not contain a sequence!."
There's no error if the 2nd parameter is removed (then the image is just copied
into the target file).
