In fact, if your images get posterized, this means you are doing something wrong, apart from the situation when you want this to happen.<br /> Don't try to reduce photos to 128 colors. Instead, reduce images which seem to have few colors as visual perception, but in reality are stored with a higher color depth. Color quantization is smart enough to keep only the most important colors - the most frequent ones.<br /> So the thumb rules are:<br /> 1. use as many colors as you need, but choose a format like PNG or GIF for images with few perceptible colors<br /> 2. use JPEG for photos<br /> 3. use true color PNG if you want to keep the maximum quality of photos</p> <blockquote><p> (There is also one problem: there are some software, like Game Maker 5, that seem to take a compressed image and decompress it again, increasing the file size. How can we avoid that? ) </p></blockquote> <p>You can't avoid this but if you work with a lossless format like PNG you won't lose quality along the way also. JPEG looses quality at each re-compression. </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=47#post-122 Thu, 22 Jul 2010 11:29:53 +0000 PHL 122@http://luci.criosweb.ro/riot/bbpress/ <p>Thank you for replying.<br /> When I reduce the number of image colours(e.g. from 256 to 128 colours), the image can get ugly due to "posterization"(the gaps left by the removed colours,I think).<br /> So I wanted to rather desaturate, because in desaturation there is no posterization. But I was disappointed to see that desaturation increased file size ( and sometimes an over-saturated image is smaller than a desaturated one).<br /> What do you mean by reducing "unique" colours? RIOT does not let me choose which colour to remove.<br /> (There is also one problem: there are some software, like Game Maker 5, that seem to take a compressed image and decompress it again, increasing the file size.

The colors are not removed, but their intensity is simply reduced. If the saturation is drastically reduced the image may compress better.<br /> But you should ask yourself: why alter the colors of an image, especially if they look good that way ?<br /> I tkink optimization should be lossless or close to lossless.<br /> If you have an image with few colors try reducing the number of unique colors instead and choose a proper format. But don't exagerate because the image must be optimized not simplified. </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=47#post-120 Thu, 22 Jul 2010 10:35:22 +0000 PHL 120@http://luci.criosweb.ro/riot/bbpress/ <p>I don't think Riot has image desaturation ability. But... Does desaturating images reduce file size ?<br /> In my experience, image file sizes have increased after I used an image editor to desaturate them. Why?<br /> I thought desaturation means removing colour data from an image, so logically file size should reduce. </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=46#post-119 Tue, 22 Jun 2010 09:27:45 +0000 luciansabo 119@http://luci.criosweb.ro/riot/bbpress/ <p>When i read with riot 0.4.1 Stable, the color of the picture is very false, for help you all the picture is BLUE and some little parts of green (very edge)!!!<br /> From help you again there are so to the RIGHT of picture, many pixels out of the picture with all colors into (random or may be the extended exifs, or other ??)</p> <p>Checked with a Pentax KX in PEF mode.</p> <p>(reported by Jpette) </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=45#post-118 Mon, 24 May 2010 09:55:55 +0000 luciansabo 118@http://luci.criosweb.ro/riot/bbpress/ <p>With 0.4.0 in beta for more than a month, it is the time now to release the first stable version of this branch – 0.4.1</p> <p>As you would guess this version fixes some issues of the beta version.

If one wants the picture to be 14cm wide, to fit on an A4 in a document, one could get a much smaller filesize, and also exactly what this person would need. A dpi of 300 at most would be nice (96~120 for screen), I think it would be useful for the screen as well. Well, indeed, in case of using cm/inch values, dpi's required.</p> <p>If I have not convinced you, please stay with your decision!)</p> <p>(2nd)<br /> Cool!</p> <p>(4th point)<br /> Hmm, I really thought this would be (very) useful. What if the user sees the image in the right pane, zoomed to, say, 46%, thinking "that's exactly the dimensions I want"? Maybe if you just provide the dimensions? The user can then enter them manually in the Resample dialog.</p> <p>Alright, that's it.

The DPI values has no impact on filesize. RIOT only keeps the original resolution and it is not necessary to calculate or reduce it for the purpose of this program.<br /> The DPI values are usually used for printing.</p> <blockquote><p>a (relative) simple masking/feather feature, that hides the one colour(s) surrounding the image. </p></blockquote> <p>Choosing the transparent color/area is planned, but I can't give an ETA.</p> <blockquote><p>indeed open translation, or something that inserts translation (localization) into the code. </p></blockquote> <p>There is already a feature request on this. If enough people want it, I will implement it.</p> <blockquote><p>adopt zoom value, actually adopt display dimensions (ie. adopt screen display image size to the Resample dialog) </p></blockquote> <p>I really haven't heard of such feature until now, and I can't say I find it useful. I think it will confuse the users, and I don't see any usability enhancement by adding this. Sorry :) </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=40#post-115 Sun, 02 May 2010 18:52:23 +0000 luciansabo 115@http://luci.criosweb.ro/riot/bbpress/ <p>It was not designed to use shorcuts and it can't use them with the current design.

It also could occur if you subsequently added tools one after another, each of which would inherit the condition. If the tool is instead reselected in the list, then the buttons appear active and the next added tool would also inherit active buttons provided you didn't change to a default tool. </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=43#post-108 Mon, 26 Apr 2010 08:04:47 +0000 luciansabo 108@http://luci.criosweb.ro/riot/bbpress/ <p>If multiple files are selected the "Remove selected" button is disabled and the user can't use this function.<br /> A simple workaround would be to use the Delete key from the keyboard. </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=42#post-107 Sat, 24 Apr 2010 15:25:46 +0000 luciansabo 107@http://luci.criosweb.ro/riot/bbpress/ <p>RIOT does not detect binary transparency in 24-bit PNG or ICO files.<br /> RIOT seems to just use the transparent color instead of rendering<br /> it transparent.

In these cases the optimized files (if saved) are not used, because a non-zero return code means return with error. This is not a RIOT bug and can be fixed for batch if you put<br /> <code>rem</code><br /> at the end of the script</p> <p>- RIOT does not handle the tool names well. If you edit an established tool's<br /> name using the configuration dialog, then a new section is placed in the INI, yet the old section strangely remains. So, the INI gets filled with several unnecessary entries of the same tools just with different names. Thus, when you restart RIOT all the old names appear in the drop-down list, making it cluttered and confusing.</p> <p>Sometimes, you can end up with two tools with the same name in the drop-down if you switch back to the old name in the same session. In other cases, a pre-existing tool's section in the INI will actually get overwritten, causing a loss of a tool.</p> <p>- When leaving Automatic Preview disabled, if one uses PNGout<br /> subsequently after optiPNG, and PNGout produces a larger filesize, the<br /> warning message is not displayed. Thus, the larger image gets shown<br /> in the window as well. </p> http://luci.criosweb.ro/riot/bbpress/topic.php?id=40#post-104 Thu, 22 Apr 2010 09:26:56 +0000 luciansabo 104@http://luci.criosweb.ro/riot/bbpress/ <p>There is a bug in 0.4.0 that does not allow to successfully use bat, vbs, js or wsf files as external optimizers.</p> <p>For these kind of files the program needs to call the<br /> interpreter to execute the script.<br /> So here is a workaround to use batch files: </p> <p>1. create a batch that uses parameters<br /> here is an example: </p> <pre><code>&quot;d:\Luci\Desktop\RIOT_Optimizer_beta\Riot\plugins\optipng.exe&quot; -o2 %1 &quot;d:\Luci\Desktop\RIOT_Optimizer_beta\Riot\plugins\pngout.exe&quot; /force %1</code></pre> <p>2.
