XnView Software

The problem still happens with some indexed images.

Repeat the same steps listed for the 1st image in this thread with the MSCHOO25.GIF attached here.

Nowadays, XnConvert can read 2-bit BMP files (aka 4-color BMPs), which is great, but sadly it can't export BMP files in this color depth.

This makes it impossible to generate BMP files for the Windows CE.

Please implement support to export 2-bit BMP files.

Can it be implemented?

Exactly. :)

For example, to convert a set of images to a specific fixed palette. A way to limit to any arbitrary number colors within that palette would still be necessary.

This would allow images to be converted, for example, to the C64 palette, or the Atari ST palette.

Also, any of the palettes ...

The Pixel Aspect Ratio metadata is not being saved when images are converted to GIF.

Tested on XnConvert v1.77 on Mac OS-X v10.13.6.

Steps to reproduce

1) Add the two images attached here (Lenna2x1.png and ShouldBeSquare1x2.png) to the Input tab
2) Clear any actions present on the Action tab
3 ...

Is it possible to have GIMP .gpl palette support on the change color depth action?

Both bugs were tested on XnConvert v1.77 on Mac OS-X v10.13.6.


Bug-1) When you change from one image to another, the Action tab preview keeps locked to the old image.

Steps to reproduce:

(if XnConvert is already running, close it an run it again)

1) Drag and drop the TAMA2.gif image to the ...

Ok. I wasn't aware that I had to rebuild the thumbnails. That fixed them, thanks!

> for preview, 512x256 & 256x512 should be expanded as 512x512 or 256x256?

For Pixel Aspect Ratio correction, the image dimensions should always be expanded and not shrunk.

This means that a 512x256 image with 1:2 ...

To make things easier, I also attached it here.

The automatic crop action sometimes does the crop the way it wants to do, and not the way the user requested.

Steps to reproduce the problem:


1) Use the attached "Reserve 12.png" image
2) In the Actions tab, add the "Automatic Crop"
3) Use the following parameters:
- Color of pixel at: Bottom ...

I just tested with XnView-MP v0.91-Beta4 on Mac OS-X. These are the results:

1) Preview

The aspect ratio is shown correctly for JPG, PNG and GIF files now.

But this problem still happens: "ideally, the image should only be expanded to adjust the aspect ratio, so no pixel information is lost. But ...

Hello,

The current posterize filter is a bit awkward. It only allows the user to select a certain number of colors, similar to what the "change color depth" filter does.

A better color posterization filter would do the same that the GIMP posterization filter does: it allows the user to select how ...

It seems that some Pixel Aspect Ratios are still not shown correctly by XnView. Like the one in this attached image.

You're right. I missed that "Bayer" = "ordered". Sorry for that.

I have another suggestion for the Change Color Depth action:

- Use a GIMP .gpl palette file for the palette. (note: the color order of the .gpl file must be preserved, and unused colors shouldn't be eliminated)

Ok, thanks for the tip!
