XnView Software

The JPEG-XL format is a non-starter regardless of its other merits if it requires Windows 7 and modern-style applications. It's a bit ambitious for a basic image codec. In the IV "competitor application" they added a 4 MB DLL for this one format about as big as the rest of the application. Not quite...

Sounds like a job for AutoHotKey. You could call XnView from the command-line and therefore still do part of the job with it. I use AutoHotHey to take screenshots in games. You can define a timer in the script or a loop with a sleep time to execute a command at regular intervals.

Here is an example. Two RGB files, normal sRGB and Apple at 1.8, look the same. The correction works on them. The grayscale files at gamma 1.8 and dot gain 10% get darker, 2.2 is close to sGray, but still looks slightly different. This is in XnView Classic 2.50.3. Irfan said to me that profiles for ...

Color profiles for Grayscale don't seem to be applied at all. Grayscale upconverted to RGB with works, gamma is applied and the loading speed is slower.

Download an earlier version before 32.0.0.371 of the Flash ActiveX plug-in and install it. Adobe has intentionally disabled it. Alternatively, use a standalone player which continues to work.

I used layer blending mode Difference in Photoshop, and increased the contrast with Levels.

This is a standard behavior of most software and allows to save multiple images at varying quality or formats, always starting from the source of the highest quality that is already loaded. If you want to reload the image, press Ctrl-R or F5. F5 is very quick and intuitive to reach.

When an image is repeatedly saved with color subsampling, the bleeding will progressively increase because the chroma is interpolated on load into XnView and decimated again. I do not know about the command-line application. There would be little generation loss if the color was left "blocky , but i...

What does the option this option do: "For 'Save as', use the original pathname the first time". The way I understand it, it should go to the directory of the currently open file, which is what I want. But it does not do that. I don't get the meaning of "first time". The other option "use same origin...

Alright, I can get used to it, and open two instances of XnView instead.

I had forgotten about this program, and now find it to be ahead of its alternatives in internal support of special formats, alpha, and that it still sports a clean classic Windows design. Good work.

What quality setting would you recommend? How big should a photo be (file size, 880px height)? JPEG is close to being perceptually lossless in a photo at about q 95 and no color subsampling ( 1x 1x 1x ). Very clean, artificial images might require q 98. The useful range of the quality slider is bet...

The DDS export option needs to be improved. 1) It only allows power of 2 dimensions and the padding is not clean, as shown in the above example. If the input height is not mod4, some rows are discarded before the image is padded to pow2 height. A warning could be presented if the image does not meet...

Is there a way of disabling closing of the current file on double-clicking its tab and pressing Esc? I often accidentally closing open files in some situations. For example, open two images side by side to compare their quality. Click on their tabs to switch between them. Ctrl-Tab cannot be used in ...
