Bug in WDP thumbnails

[foxyshadis]

The wdp thumbnails show up as garbage of some sort. It's not totally random, in the uninitialized memory sense, because several copies of an image have the same look and it's vaguely recognizable. Still garbage though.

Example image

You can open it in xnview and save it to another format to see what the thumbs should look like.

Hi !

• Your sample looks so normal here as a thumb nail, despite I use very small thumb nails (exactly the size shown below) :

    

• I guess it could look better with a larger thumb nail size, though.

• Same when saved as PNG…

Your sample looks normal here as a thumb nail but only if Options >> Thumbnails >> Use high quality is not active !
If I activate High quality for thumbnails : and rebuild thumbnails your sample is showed as garbage !

Thanks for clarifying. After I saw Clo's comment I was trying different options to make it work, but I never tried that one. :p

I've updated the plugin for HDPhoto http://www.xnview.com/download/plugins/wmp.zip

The left thumbnail was made with the old version (v1.90 beta 3) of Xwmp.dll, the right one with v1.90.4:

Can confirm thumbnails are fixed for 8-bit images. 16-bit have no thumbs, and crash on opening, example image. Also, the dimensions are misreported now. I'm pretty sure it's using the DC coefficient speedup trick, which is cool, but the dimensions are now reported as 1/8 of their actual values.

Not major issues, I don't even know how much support xnview is supposed to have for 16-bit images at all.

Now that Vista's making its big splash, I wonder how the format is doing. It seems to have some recognition on forums, but no photo site lets you upload it yet. :p

Hello !

• I can confirm, your new test image is not displayed at all, neither in “View” or as a thumb nail…

• Here, the Preview displays hexa

…Not major issues, I don't even know how much support xnview is supposed to have for 16-bit images at all. …

• IIRC, XnView doesn't support 16-bit per channel images (yet ?)…

Happy Easter (or whatever's left of it) to you too, Clo!

That's no typo, that's what it says in the DLL's file properties:

Hello!

• You are talking of 1.90 beta 4, but you wrote 1.90.4, that indeed it not the same !

- There a mistake from Pierre (?) about the sub-version, I guess.
- The version number shown in the properties sheet is 1.90.0.0, that doesn't match

• For short, generally I use the German “ß” character for “beta” because it looks ~ the same than the Greek letter…
- So, it's not confusing…

the second example is not viewable in v1.9.1 ?

another thing how to convert from png, jpg to wdp in XnView?

[foxyshadis]

It isn't possible to do that in XnView (yet?), only an input plugin exists. XnView doesn't support photoshop input/output plugins, although that would be a pretty cool wrapper plugin. =D

Good to see you posting again, foxyshadis! For a while I though we had lost you.

You can save to WMP/HD Photo format with the newer version. But you have to do a little tinkering first:

still i cant use the hd photo plugin to write the files.. please help..?

In your xnview.ini, try to remove the [plugins] section

Deleting the following line from the [plugins] section of xnview.ini did the trick on my installation:

Code: Select all

23=Xwmp.dll|262|wmp|WMP|wdp;hdp;

Obviously it was left behind by an earlier version of xwmp.dll. The next time I started XnView, version v1.90.4 of the plugin created a new entry:

Code: Select all

23=Xwmp.dll|772|wmp|HD Photo|wdp;hdp;

XnView doesn't support photoshop input/output plugins, although that would be a pretty cool wrapper plugin. =D

You're referring to the beta release of Microsoft's HD Photo Plug-in for Photoshop (HDPhoto.8bi), right? I'd be surprised if there's a way to make it work with XnView. Even my old version (6.0.1) of Photoshop didn't like it: “Unable to find an entry point named GetModuleHandleExA in DLL Kernel32.dll.”

• Setup plugin Adobe 8bf - Adobe Camera RAW 3.4?
• Good plugin, doesn't work with xnview
