Plugin function not working in mac runtime

[Nicolaus Busch]

Hi forum

I'm using this function to generate a thumbnail:

ImageThumbFromURL( Substitute( $Pfad ; "\\"; "\\\\"); 140 )

This works perfectly well no matter whether $Pfad is a URL or a local path in Windows runtimes, in Filemaker Advanced on Windows an on Mac 10.6 and 10.7

The same code executed in a runtime on Mac generates nothing but the text "ERROR" in the thumbnail field. The plugin ist loaded and visible in the list of plugins.

Any ideas?

Is this a module you wrote yourself? If you can reproduce the error and send us a bug report we can take a look and see if we can identify the issue.

Hi Brent

I try to produce the report on the mac tomorrow. The function I use is this, I found it somewhere in the forums:

RegisterGroovy( "ImageThumbFromURL( url ; maxpixels )" ; "import javax.imageio.ImageIO¶

import java.awt.image.BufferedImage¶

import java.awt.geom.AffineTransform¶

import java.awt.image.AffineTransformOp¶

¶

BufferedImage img¶

¶

if (url.indexOf("://") != -1) {¶

img = ImageIO.read(new URL(url))¶

} else {¶

img = ImageIO.read(new File(url))¶

}¶

¶

Integer maxWH = img.getWidth()¶

if (img.getHeight() > maxWH){¶

maxWH = img.getHeight()¶

}¶

¶

¶

Double thumbscale = Double.parseDouble(maxpixels) / maxWH ¶

¶

AffineTransform transform = AffineTransform.getScaleInstance(thumbscale, thumbscale)¶

¶

AffineTransformOp op = new AffineTransformOp(transform,null)¶

BufferedImage scaledImage = op.filter(img, null)¶

return scaledImage" )

"ERROR" means Java throws an exception.

WIth the function SMLastError you can get more details about this exception. Just put a "Show Custom Dialog" script step after your function call that shows SMLastError.

I made a mistake here, it doesnt work with the full version either. SMLastError is "javax.imageio.IIOException: can't read input file" with $Path reading like "MacDisk:library:test.jpg". I guess I have to transforme the path first?

Problem solved, with a path like /Volumes/MacDisk/Library/test.jpg everything is fine
