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

Please let me know if you find it useful!

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?

[joctee]

Glad you liked it!

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

* Alpha is rendered black, not as alpha.

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.

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

I made a new version where alpha is working. See the top most post for download link. (Thanks Nudel for the alpha hints)

Wow coolness!

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

x64 version is now available. See top most post for download link.

This plugin may break in a future version of Opus if we remove the non-Unicode API.

If you find the plugin isn't working, try this alternative one which can handle the same formats and uses the Unicode API:

Universal Graphics Viewer Plugin

We have just released a first beta of our DOpus Universal Graphics Viewer Plugin (utilising the excellent GFL graphics library), with support for HDR (and lots of other formats - see plugin About dialog for full list of supported file extensions). We…
