Plug-ins for RIOT

Even if RIOT is available as plug-in for other programs like IrfanView or GIMP,  RIOT itself can be extended with plug-ins to enhance it’s functionality.

Currently only input plug-ins are supported. In the future I hope more plug-in types will be added.

Download the RAW + HDR plugin package – allows you to open HDR, OpenEXR and RAW camera images

Special notice to IrfanView users
IrfanView has bundled into the plugin collection the Lite version of the RIOT plugin.

Here you can find the extended version (also FREE)  that goes beyond Lite version offering extended functionality.

I always recommend the extended version over the Lite one.

  5. toma says:

    hello.
    i wanted to suggest, if you can make an option for RIOT, to be shown it in right click menu for images. (similar as “right click image converter” OR “Light Resizer” has).

    this option should be changed from RIOT preferences.

  6. Thom says:

    Much quicker & easier to use than opening Photoshop CS.

  7. the best programm for immage

  8. Harald says:

    Wonderful software. Can you please include some more saving of the settings, i.e. width and hight of the resizer module? This would make it even more comfortable. Thanks!

  9. Lonnie says:

    Love the Riot software. It works better than most compressors with better results. This should be everyone’s go to tool for compression.

    Perdonen mi ignorancia, pero no sé como gravar la imagen optimizada cuando le doy “Save as” Gravar como..me grava la imagen sin optimizar.
    en que estoy fallando?
    Atte

    Pardon my ignorance, but do not know how taxing the optimized image when I give “Save as” Taxing as gravel .. me unoptimized image.
    where am I failing?
    Atte

  15. Larry says:

    I had been looking for an easy program to batch resize some images and this program worked perfectly. Thank you and keep at it.

  16. this is great soft ware for me i will download it from you admin thanks

  17. Saul says:

    64-bit version please, I have asked Irfanview to get their 64-bit version too.

  18. admin says:

    @Ger: the RAW + HDR plugin package is for RIOT not for IrfanView

  19. Ger says:

    The RAW + HDR plugin package allows you to open HDR, OpenEXR and RAW camera images. I suppose you mean open in IrfanView. But IrfanView version 4.33 can open RAW and RW2 files wthout the RAW and HDR plugin package. Can you explain? I have copied these three fip files to the IrfanView and also to the IrfanView\Plugins folder.

    Installed Plugins in IrfanView shows no difference, neither does the IrfanView user interface.

    Your link detailing about the Lite and Extended version gives an error 404 Page not found.

    In other words, can you pls tell us how to ge these fip files working and how to verify that IrfanView with these fip files actually offers extended functionality.

    Thanks.

  20. Alce says:

    This works great on XView. Thank you

  21. admin says:

    Not yet, but probably in the future

  22. Bangon Kali says:

    Is there a 64 bit version of this program? It would be great to have a dedicated 64bit version of this. Thank you for this great program!

  23. admin says:

    Currently there is only read support for JPEG 2000.
    Write support will not be added until this format will be widely supported on web browsers.

  24. Saul says:

    Any JPEG2000 support in the future?

  25. admin says:

    Hello Harry
    Thank you for your support. If you are using the RIOT IrfanView plugin you can copy all the 3 .fip files in the main IrfanView folder or in the plugins folder.

  26. Harry Ward says:

    I use Irfanview, and just updated RIOT to 0.4.6. Thanks for making the extended version of a fabulous program. It installed in Irfanview just fine.

    I also downloaded the plug-in file. You said: “Even if RIOT is available as plug-in for other programs like IrfanView or GIMP, RIOT itself can be extended with plug-ins to enhance it’s functionality.

    Download the RAW + HDR plugin package – allows you to open HDR, OpenEXR and RAW camera images.”

    However, I can’t figure out how to get RIOT to recognize the plug in. I extracted the .zip file, and got 3 .fip files, but I don’t know what to do with them, and I can’t find anything in RIOT to tell me.

    Thanks in advance for your assistance,

    Harry
