Summary

Hello,
I use Irfanview V4.20 that uses the Riot.dll to set .jpg file size. This is a great new feature in Irfanview. Unfortunately, this feature cannot be accessed via the command line. Is there a plan to give this option to the riot.dll in the future?
Thanks
Frank

Is there a way to create a multi resize for several photos?

I use it as plugin in Irfanview but also using the latest riot.dll the Metadata is always discarded (i tried with several types of jpg images made with several kind of cameras using EXIF and IPTC). I tried opening images directly into the plugin but always the metadata is discarded and all checkboxes flagged and impossible to put out the flag.
Can you fix this, please?

Anyway, congratulations for the plugin, very very useful.

Save as button in the irfan view plugin doesn’t work. What could be the problem ?

Dear Lucian,

what a great program you made!! Hats off!

Your side-by-side-image-view is great of course. But it is only useful for significant reduction in quality. Actually minor differences CANNOT be seen side-by-side!
That’s why professional programs like Photoshop use an “in-place view”, where you click (on the image or a button next to the image) and the image changes from “original” to “optimized” as long as the mouse button is pressed. With the two images being exactly at the same location, you can actually see, which pixels change/move. This way you can adjust the quality slider gradually until you reach a position where you cannot (or nearly cannot) see pixels change, if you want to optimize your image but still want to keep the quality virtually unchanged to the human eye.

So therefore I’d suggest that, if you can, you would let the user click on a button (or into the image) and the image switches from “original” to “optimized” as long as the button is pressed.

I think your program already is capable of doing these things, so it would be a very minor programming effort I guess.

For any questions please e-mail me.
Thanks,
Amaury

Well done, maybe I’ll leave Adobe Fireworks forever

… suggestion: add “sharpen color edges” feature, sometimes it can help a lot.

Thanx for effort

Greets, thank you for adding the option for EXIF in this version! It has really made a significant difference in my work flow.

On a side note, I submitted your program to http://www.majorgeeks.com for consideration, and it was posted as a link today! I did this since I believe others may find your work as useful as I have, if you happen to see a spike in traffic that could be the cause. If the submission was unacceptable I apologize.

Very good! But, please consider this:

-count colors and auto-set bit-depth: sometimes you find 24-bit encoded images which actually contain just 100 colors or 13 so pallete reduction is obvious.

-reducing depth to 4 bit/pixel for 16 colors or less (it can be done manually in irfanview and compresses better than 8 bit).

-allowing non-dithered B&W 1 bit/pixel: very easy and useful.

-adding color dithering (but disable it by default because it tends to compress worse)

Hello Lucian,

Thanks for this great plugin.
I did find the following issue:
With the version 0.1.7 plugin in Irfanview I can click on Save for Web… when I have a .pdf file loaded. This works. With version 0.2.0 of the plugin I get an error message: \\"Error loading file.\\"

Arthur.

Wow, the first time I search Google for \"reduce image size\" I found InfranView, and through its plugin I knew InfranView could do it ( without notice of RIOT ) but today when doing some more details search, I find out the true hero is not InfranView but RIOT, many thanks to Lucian !

But, as a developer, I want to try to use the FreeImage.dll and Riot.dll as well, is there API for these librarys ? Thanks

Thanks for considering the in-place comparison, Lucian. Cool!

A long time I using Irfanview but only today found riot plugin.
Riot the best extension for Irfanview! It\’s more power than Adobe Photoshop Save for Web…
Thank you!

I think that the crop function is the first function to add in order to minimize significantly the size of images. Next, an automatic crop function is useful for graphic images.

I tried the Riot 0.2.1 program and was impressed at the simple design to compare and compress images. I did notice a problem and read through the other comments to see if others had the same problem. When I found out the 0.3.Beta release was available, I decided to see if it solved the problem. Sadly, it did not.

Bad Save Name:
Starting with a JPG source file, save the compressed version as a JPG file into a new directory. Then switching the output type to PNG file format, another save will display that the filetype will be PNG but the filename itself does not change and so it contains JPG as the last three characters of the filename. A save, prompts to replace the previous file. If saved, it replaces the output JPG file with one of the same name, except it is a PNG internal. Most programs know to change the extension to the selected filetype before saving. I hope this program will adopt that method of output filename.

I liked the idea that an \"in-place\" compare would be easier to use, and was excited to see it implemented. It was a bit tricky to find out how to get the in-place compare but it didn\’t take too much hunting to get to that.

In-Place Compare output image eventually fails to change when output is monochrome:
I started experimenting with the various compression and output choices. I switched to PNG output file and monochrome color. Then I switched back to GIF, then JPEG, then PNG again, trying different compression choices. Somehow I got to a mode where the before and after both had color, although the output was clearly set to Grayscale. It apparently is a failure to update the output image area properly.

The “Automatic Crop” function is well suited for images with a self-coloured frame (photo with a frame, screenshot of a graph) and is used to suppress automatically this kind of frame. Several image editors get it : http://www.xnview.com (Alt+Y), http://photofiltre.free.fr ,…

Reduced size of my website from 2,57MB to 953kB.
THX!!

When can we expect the Lite dll version to return? Has it been discontinued with the release of 0.3?

Also, since there is no dll currently available, can you at least put 0.3 back up until 0.3.1 is released? The only choice now is the ansi 0.1.15.

Thanks for the great program!

BTW, IrfanView has an \"Auto crop borders\" function (Ctrl+Shift+Y), so RIOT certainly could.

Alvaro made a suggestion that imo would really make RIOT better:

“-count colors and auto-set bit-depth: sometimes you find 24-bit encoded images which actually contain just 100 colors or 13 so pallete reduction is obvious.”

Keep up the good work,
Aaron

What has become of the MSI installer option? It seems you have quickly abandoned it for an EXE setup with 0.3. Will it return?

Appreciate all your efforts,
Sunny

EXE is preferable, but I was wondering about MSI after reading this:

http://www.vbforums.com/showpost.php?s=4b2196c983c7491a1c9c1f34badb4c49&p=3115321&postcount=3

Based on what you said about free options being non-existent, I take it you had to pay to produce the first MSI you released?

RIOT is a rather simple program comparatively, so I would imagine that you could find something usable here for free. Unless, nothing has really worked for you and your project.

http://www.installsite.org/pages/en/msi/authoring.htm

From the standpoint of a developer, I understand reliability is paramount. I agree that software should be useful for as many systems as possible.

I am trying to determine though, if MSI is better for the user installing without administrative privileges, as this is convenient. Would a network install facilitate this? And would MSI make it smoother, especially since it supports Group Policy? I understand that the ZIP option is good, but the setup option is easy. Can EXE handle all this (including a silent option), or it doesn’t matter since your MSI tool is not powerful enough anyway?

Hi there!

Lovely software you have, I use it everyday!

Suggestions:

Could you give us a…

1. Reopen command that opens the original file again, so we can easily resize and save the same file without going through the Open dialog over and over to fetch it. This is good when you want to make several versions of a file for the web!

2. Revert button that undos any selections we’ve made since starting the program, so we can use our defaults again if we want to discard our changes to the image. This is good when you want to work with several images, but don’t want to restart the program to get your defaults back (by not saving settings on exit). Also good if you made changes and don’t like them, or forgot what you did!

Hope you like…Bye!

Could the Save dialog be hidden and simply show the Replace warning only (like in IrfanView when using its Save)? It helps save a click. THX!

RIOT is amazing!

Me again!

Almost forgot. Making the Save dialog hidden would be an *option*, not the exclusive design, since some people might want to save an image in the same folder as the original, and would need to have that dialog to change the filename.

Soda out.

Riot rocks!!!

Hello,
Wonderful software! One of a kind.

I want to beg, beg, and plea some more for a BATCH conversion feature of either 1) file size (irfanview has this, I know) ***2) Save as % (e.g. 80%) quality***.

This is absolutely the most critical feature missing IMO and a thorough Google search shows a lot of users looking for this feature.

It’s a shame this cannot be done in Irfanview (One can save to 80%, but not using RIOT ‘method’)

Great work, cant wait for batch in 4.0.

Gracias.
Muy buen producto, y de uso libre
exelente calidad de compresion, los felicito por su logro.
sigan asi, saludos.

Hi – great concept. Looks like exactly what I’ve been searching for. I see a bug though, preventing me from actually saving the file: “Access violation at address 76B5633E in module’comdlg32.dll’. Read of address 6DCB16C8.”. Running Vista SP2 on a Dell Vostro 1710. I access Riot from IrfanView 4.25. Any idea? I’d be available for experiments …

Thanks for fixing the Vista SP2/comdlg32.dll issue in v0.3.4 Beta.

RIOT is an excellent and extraordinarily useful tool, especially alongside IrfanView – Thank you for developing it and working with Irfan.

Gimp version works fine but i will found more handy use from my viewer

Irfanview is a good viewer but i use Xnview any hope for a xnview version ?

I think the Xnview author will be happy to help for all technical details if you contact him by the forum

XnView already has a File | Export command which does some of the things RIOT does.

this is a brilliant tool and I found it knocks alot of commercial plugins such as superpng out of the water… the only problem I have found (not a bug, just an issue) is that it all ways uses a threshold for transparency… where certain applications require a gradient. (such as video game engines, where the alpha is used as a height map)

do you have any fixes or workarounds?

Hi,
I use (and abuse of) riot since several months but now I’m on mac os x snow leopard.
Are you planning to make an os x version?
Thanx for this beauty

I only have One wish: Batch processing.

If I could select one Input and Output folder. Press start. That would be heaven.

Today I use the Irefanview plugin on my Camera pictures, and shrink picture by picture. It’s a tedious task. But the compression is amazing.

If you could manage this feature I’ll be the first to spread the word to everyone I know. I could earn you an immortal spot along side Irfanview.
