You're right. It would be a shame not to reuse the list capability here.

Maybe a better name than dds:fromlist would be dds:mipmaps_from_list

since dds:mipmaps_from_list is more coherent with the current dds:mipmaps

but then again, this might confuse the user as to whether dds:mipmaps has anything to do with dds:mipmaps_from_list

Hmmm... ambiguity is not good.

Wouldn't it be more logical to take all the images in the current list, with a simpler define? Like this: convert image1.png image2.png image3.png -define dds:fromlist image1.dds I also though about using this but I had the idea that this would be bad if you wanted to write multiple files in the ...

This is great news! :) Glad to hear you are willing to consider it. Eagerly awaiting any further developments! Just for clarification are you saying you want only one output image whose different resolution maps come from the different input images? Or are you asking for multiple output images with ...

Thanks A PM has been sent. I'll post any responses here.

searchcode.com to the rescue.

I would like to talk to the person(s) who wrote the writer to determine if this is even feasible. He/she/they must be out there somewhere...I'll have a look around.

Thanks, Fred. I'll look into it. (shuffles off to read about -define and what it can do for DDS files...) maybe the current DDS writer can be modified to assemble mipmaps from an imagelist, rather than autogenerating them from a base image. Hmmm.... In the meantime, I found this: DirectXTex texture ...

Good call. The closest to a format description I have been able to find so far, is this: Reference for DDS https://msdn.microsoft.com/en-us/library/bb943992(v=vs.85).aspx Programming Guide for DDS https://msdn.microsoft.com/en-us/library/bb943991(v=vs.85).aspx and yes, it does support a mipmap ...

Given an image list containing quadratic images with side lengths in powers of 2, would it be possible to write these out to a dds file as mipmaps? For example: image list contains 6 images: image 1: 1024px x 1024px image 2: 512px x 512px image 3: 256px x 256px image 4: 128px x 128px image 5: 64px x ...
