Remove Background & Anti Aliasing.

[UnixNewbie]

Hello

May I preface this post by stating I am extremely new to ImageMagik.

I want to batch convert a large number of .psd to .psd and .png - and remove the background to leave the background transparent in the process.

A friend who is handy at this sort of thing helped me to create this script:

#!/bin/sh
SOURCE=$1
PNG_NAME=$(basename $SOURCE .psd)
echo "Converting $SOURCE..."
mkdir ../converted_images > /dev/null 2>&1
convert -background transparent "$SOURCE" -flatten ../converted_images/$SOURCE
convert -background transparent "$SOURCE" -flatten ../converted_images/$PNG_NAME.png


The issue is with anti-aliasing - the resultant images have jaggedy edges around the object.

If anyone could repost this script with suggested changes in the script I would really appreciate it - I am still not at a level where I would know where to put the extra commands.
Again - I haver only been learning this stuff for a few weeks now so please excuse any glaring inconstancies - we all have to start somewhere! Many thanks in advance.

Using Terminal in OSX. Have installed Brew and ImageMagick:

I assume this is the method: http://tech.natemurray.com/2007/12/conv ... arent.html

Am unable to modify the code to make it work.

Perhaps you should post and example input image and your output image to some place such as dropbox.com and post the URL here so we can see exactly what you are trying to do.
