I want to flatten a layered tiff while retaining the alpha channel.

using this:
convert ../source.tif -alpha on -layers flatten -filter lanczos -resize 1024x1024 -unsharp 1x0.5 %temp%/temp.tga

Now I'm faced with building the tool installs for the art team, and I'd prefer to keep it a lightweight as possible.
I see the install folder for IamgeMagick is around 50 MB

I find that ...

So I've been converting layered tiffs (dozens of layers) using this command

convert in_file.tif -alpha off -layers flatten -filter lanczos -resize 256x256 -unsharp 1x0.5 out_file.tif


but the result is that only the bottom layer gets resized, the remaining layers get cropped.
if I set the format ...

There are a few command line tools for dds conversion.

Nvidia has nvconvert, part of Nvidia texture tools https://code.google.com/p/nvidia-texture-tools/
ATI hasTheConversionator ( which i am using) http://developer.amd.com/resources/archive/archived-tools/gpu-tools-archive/the-compressonator ...

thanks again!

thanks for the response. I'm not unix but win7.
your answers seem enough to point me in the right direction.

I'm new to image magick, working on a game texture tool for my studio

I need a batch-able tool that can take 4 layered 1024 tiffs:
filename_diffuse.tif (24bit)

filename_specular.tif (8bit grayscale)

and perform the following ...
