B3: Icons in preview

[Dreamer]

Some icons in preview look strange. Thumbnail is OK.



Edit: it looks the same also in fullscreen and viewer, only thumbnails are OK.

Sample to test:

Hello !

• The icons previews are OK here…
- I'll check the faulty icon itself a.s.a.p.

Again…

•Your sample is a multipage icon containing 23 pages (formats), including a 256² one, 4BPP, certainly PNG-compressed.
- The size of that original icon is 315,740 bytes.
- XnView displays only three of the B & W pages in View, the Preview is wrong, the transparency is not rendered.
- I saved a copy in GreenFish Icon Editor - without PNG compression for the 256², the file size is 588,486 bytes -
then, XnView displays all pages in View, but the preview is still stuck on the fisrt B & W format in the file…

• I saved another copy in GreenFish Icon Editor with its PNG compression, the file is 306,317 bytes.
The XnView behaviour is same than with the original…

• Pierre has his work cut out…

For thumbnail, xnview try to find the best icons. And yes there is a problem, only 4 icons can be viewed, your .ico is not good

Hello !

• This ICO file is good, but :

1. The first page is taken for the thumbnail and preview, and it's a B & W one (1 BPP).
- So, the transparency is shown as black.
- XnView does NOT look for the best icon in the multipage ICO.
- I changed the pages order in GFIE, then the first is taken, still.

2. XnView doesn't support the 256² (Vista) PNG-compressed icon.

¤ Please, read my report above…

No some data seems to be bad!

2. XnView doesn't support the 256² (Vista) PNG-compressed icon.

???? XnView support them, could you send me a sample?

• You can get a sample HERE

- The same non-compressed works in XnView, the sample is saved as compressed in GFIE which conforms the norms…

- None standalone such file works here, and puts the mess when embedded in a multipage ICO, like the Dreamer's one.
- Whether it's the first page, that doesn't work at all (unknown format message).

Ok, i'll try to find some info about PNG compression for ICO

It's fixed in 1.94 RC! Wha ! Fast , thank you !

• But the Preview shows the first page still…
- Maybe it shoud be desirable to ignore the 1 BPP pages up to the first having let's say,
at least 4 BPP as colour-depth to use in the preview?

Still the same in v1.94.

You want to view the best icon like thumbnail?

Hello !

• Like I said above, the first page is still used for the thumb nail and the preview…
- In the Dreamer's icon, it's a B & W one. So, if possible,
it should be nice to ignore the B & W pages up to the first coloured…

Temporarily, you could change the order of the pages using GFIE or any other good icon editor,
in order to get a coloured icon as the first page.
- In GFIE, that's very easy, just D&D and save…

You want to view the best icon like thumbnail?

Yes, if possible, because in some cases the first icon is quite unusable and it's strange that thumbnail looks (much) better than preview/fullscreen view.

[Dreamer]

In Browser mode it's better, color icon is used, the same as for thumbnail, but not the best (largest) icon. In view/edit mode it's still the same - only small b/w icon.

1.95 beta 1, Win Vista.

Not the largest??? Please send me a sample?
