XnView Software

There appears to be list of protected extensions. On a new Windows installation the ".bmp" extension cannot be changed, but ".reg" can be changed normally. Have people found where this list is to hack it?

Edit: On Server 2022 only these extensions are protected. Strangely, some important ones like ...

Well, then it turns into "Windows Seven" with eye candy and bloat. I'm an old school user, and believe that Microsoft offerings in the multimedia area (like thumbnails in Explorer) are superfluous. With movies you often end up with a black frame, slow performance and files locked for moving.

I'd ...

I'm surprised that there is next to no apparent color smearing with the XYB output, which by default has chroma subsampling. I picked the nastiest blue and red combination I could find, and I only saw a faint white glow. I wouldn't use this format because it relies on ICC to fix up the colors ...

The "MP" version of XnView is a bit heavy . It contains a few dozen MB of video codecs. Because of this, it doesn't run on Server 2008 R2 without the Desktop Experience Pack, due to being linked against MFPlat.dll and other Media Foundation DLLs. Usually everyone already has one or a few video ...

I can't get the hotkey processed from XnView Classic inside games. I assign F11 or Shift-F11, choose Desktop as the capture source, and no file is created. It works from within Windows GUI.

Many recent games use what is called "deferred rendering". They put the image into an intermediate buffer for ...

XN only supports "round" image dimensions such as 1024*1024. From how the rows are misaligned, you can clearly see there is a width mismatch issue. If you ever opened RAW files, you'll recognize it. DDS support is still very limited. It only outputs DXT5 even if there is no alpha, and no mipmaps ...

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 ...

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 ...
