Piping problem about 2dimagefilter

Convert error message seems not related to ImageResizer. Possibly you'll need 
to specify the that the data from stdin is in png file format via command line 
parameters in convert.exe.

I change the command with this :

ImageResizer /load imagein.png /resize auto "xBR 3x 
<NoBlend>(thresholds=0,vbounds=wrap,hbounds=wrap,radius=1.00,centered=0)" 
/stdout | convert png:- imageout.png

But another error message appear:

magick.exe: Improper image header `-' @ error/png.c/ReadPNGImage/3999.
magick.exe: no images defined `output.png' @ error/convert.c/ConvertImageCommand
/3106.

As I said before, I tried ImageMagick Convert with Pngnq-s9, but none of both 
error that I mentioned appear. Could you mention working example to prove that 
there is no problem with ImageResizer.

Thanks

I think I know where the Problem could be. ImageResizer outputs status messages 
to stdout before the image data is sent to it and ImageMagick can not 
distinguish both from each other. I'll figure out a way to supress any status 
messages when an stdout parameter is present.

I have a similar problem. Converting files works fine except when using stdin

# convert test.png test.gif
# cat test.png | convert png:- test.gif
convert: improper image header `-' @ error/png.c/ReadPNGImage/4000.
convert: no images defined `test.gif' @ 
error/convert.c/ConvertImageCommand/3106.
