SGI image viewer plugin

Postby joctee » 21 Feb 2007, 01:09

This plugin lets you read .rgb, .rgba, .int, .inta, and .sgi pictures in dopus!

Please let me know if you find it useful! :)

About the format:
http://en.wikipedia.org/wiki/Silicon_Graphics_Image

Release 1.0.1 is now available

* Alpha is rendered correctly
* Faster loading times.
* Statically linked (means that it will probably work for all of you that were unable to use the previous version)

Download rgb-x64.zip for 64-bit Directory Opus and rgb.zip for 32-bit Directory Opus.

Awesome! This is much appreciated.

While you are at it, you haven't considered to make viewers for other useful graphic working formats like .exr and .hdr? :)

Glad you liked it!

It is not impossible that I will make a hdr plugin later this year. Time will tell.

Is that because it's difficult to get the alpha channel from the image format, or because you don't know how to send it to Opus?

There's a flag DVPFIF_HasAlphaChannel which plugins can set when returning bitmaps to tell Opus that the pixels are 32-bit RGBA values. (i.e. the Reserved byte in the RGBQUAD struct is the alpha value for each pixel.)

I have the alpha channel from the image format, but I haven't cared about finding out how to send it to dopus.

There's a flag DVPFIF_HasAlphaChannel which plugins can set when returning bitmaps to tell Opus that the pixels are 32-bit RGBA values. (i.e. the Reserved byte in the RGBQUAD struct is the alpha value for each pixel.)


Your hints are appreciated, thanks! I will have a look at it when I get some hours of spare time.

Wow coolness!

SGI and PNG are my favourite images when rendering. Cool to be able to view SGI in Dopus directly! Thanks a bunch!
