Question

I have successfully used the following command line to create a new GIF image with some simple text

convert -size 100x100 -font arial label:blah output.gif

I would like to achieve the same result using the COM interface from VBScript, but have not been successful in passing in the same parameters in. Here is my code…

Dim img
Set img = CreateObject("ImageMagickObject.MagickImage.1")

Dim fnm(6)
fnm(0) = "-size"
fnm(1) = "100x100"
fnm(2) = "-font"
fnm(3) = "arial"
fnm(4) = "-label"
fnm(5) = "blah"
fnm(6) = "C:\temp\example.gif"

retval = img.convert(fnm)

wscript.echo("retval " & retval)

I execute this code as follows

cscript example.vbs

and the output I get is this, and no GIF file is created…

I’m on Windows7 using ImageMagick-6.7.4-Q16

Does anyone know what I am doing wrong?

[Edit]

In response to Ekkehard’s answer I have also tried not using an array. This code will create an output image, but the label is not applied. I also have to pass in a white image as an input as it will not work without one.

msgs = img.convert("C:\temp\blank.gif", "-size", "100x100", "-font", "arial", "label:", "blah", "C:\temp\example.gif")

Answer 1

In the end I gave up trying to get label to work when using the COM+ API and have a solution that uses -draw instead. Ekkehard was right about not using an Array, and instead use individual arguments as shown below.

msgs = img.convert( "c:\temp\blank.gif", "-font", "arial", "-pointsize", "36", "-gravity", "center", "-fill", "blue", "-draw", "text 0,0 'blah'", "c:\temp\example.gif")
