RIOT 0.3.4 Radical Image Optimization Tool

RIOT - Radical Image Optimization Tool by Lucian Sabo is a free program designed to efficiently optimize images for the Web and applications.

Reduce image file size of your pictures.
Saving images for web/email/other media with the best compression
ratio and quality.

Choosing the right format then choosing the right parameters are the key factors of smaller files.

Previewing the resulting image and the projected filesize will help the user choose the best settings. This kind of image optimization software is often called “Save for web”.

RIOT key features:

* open multiple graphic file formats by looking first at the magic number (it does not need file extension to recognize format)including support for uncommon images types (up to 128 BPP, integer and floating point. EX: hdr images, 16 bit grayscale, etc). Adaptive logarithmic tone mapping algorithm (Drago) used for HDR images
* save and optimize JPEG, GIF and PNG with a simple, clean user interface
* works in dual view: (original – optimized image) or single view (optimized image). Automatic preview of resulting image
* in-place compare function (alternativelly display the original image over the optimized image to notice small pixel changes)
* compress files to desired filesize threshold
* fast processing (all is done in memory); see instant results including resulting filesize
* decide if you want to keep metadata (comments, IPTC, Adobe XMP, EXIF profiles, ICC profiles). Unsupported metadata is removed
* transfer metadata between image formats (destination format must support them)
* common tools: pan and zoom, rotate, flip
* resize image by using well known resample filters (ex: Lanczos3, Catmull Rom, Bicubic, and others)
* the compression and the results are comparable to those of commercial products.

v.0.3.4 - 10.10.2009
- DLL version: fixed comdlg32 access violation when using the save button in Vista 32bit SP2 (not tested on Vista 64).
- new fullscreen view
-added support for all Photoshop supported color modes to PSD loading (with the exception of 32-bit float RGB)
- improved speed for jpeg encoding & decoding by 17% (using SIMD optimized code)
- improved speed of zlib compression (used for PNG) by 30% (using ASM optimized code)
- Bugfix: Riot.ini is in the Riot folder with write permissions, but Riot
creates and uses Application Data folder. Fixed !
- The Save button is now context sensitive - meaning it is automatically disabled and enabled when needed (ex: disabled after Save to see the operation completed succesfully, disabled if the autoamtic preview is not active, etc)
- added option to show the "Save As" Dialog on the "Save" action. Default false, requests only replace confirmation if file exists or shows the dialog if the file does not exist.
- the last used save folder is now stored and used each time the user presses "Save as"
- DLL version: the image resolution (dpi) is now imported directly from the DIB. Benefit: When used as irfanView plugin RIOT can keep now the resolution without the need to activate import ancillary info.
- improved exception handling when saving a file
- flicker reduced or eliminated on most controls
- fixed some minor issues and potential access violations
- updated libraries libtiff (3.9.1), libpng (1.2.40), FreeImage (3.13.0 and from official CVS)
- moved shortcuts from menu to global actions to make them usable in fullscreen
- added new hidden configuration variable for use within Riot.ini: UseLatestCommonDialogs (0 disabled [default], 1 enabled). When enabled Riot shows the new Vista dialogs. When disabled the old XP style dialogs are shown in Vista.
Note that the IrfanView plugin gives access violations when using the new dialogs.
- DLL version: fixed black background for icons in some rare cases (no manifest in calling app)
- other minor improvements
