I have what looks like a badpixel issue with DNG files, same as post 670
http://chdk.setepontos.com/index.php?topic=6341.msg81851#msg81851
Are you using DNG version 1.1 or DNG 1.3 ?

If you are using 1.3, try 1.1. DNG 1.3 uses a different badpixel removal method, which doesn't require badpixel.bin, but isn't supported by most non-adobe raw software. In programs that don't support 1.3, you will see the same effect as in the post you linked.

You're right on it, changing DNG to 1.1 does the thing!

I use ufraw under Ubuntu. Any Linux raw software I tried gave me these spots with DNG 1.3. Darktable is able to read the CHDK CRW files for this camera, though, without spots in the result, but the conversion is so-so and getting an acceptable jpg is a lot of work.

Thanks a lot!

If you don't mind building your own version of ufraw, then you can try my patch for that program to get it to automatically fix the bad pixels in DNG 1.3 images.  You can get the patch at: http://chdk.setepontos.com/index.php?topic=9443.msg98900#msg98900

I've also found when enabling Viewfinder in livegui colors are somehow unreadable. Is this normal?  (see attachment)
Patch and compiled version for 100c in attachment.  Please test it and report.

Hi natraf!

I've tested your patch together with 100c version. I've just copied all files from both attachments to root of SD card. <- is this the right method?

So now my root SD card looks like this:
Code: [Select]
changelog.txt
CHDK
DISKBOOT.BIN
DCIM
ixus220_palette_trunk2778.patch
readme.txt
vers.req

I've noticed that zoom bar is not visible even though if I change fps to 30. (see attachments)  Wat is good fps rate anyway?

I've also noticed when fps is set to 10 and in play mode and then I press menu and then rotate submenu it takes near 10seconds to show correct colours. If fps is set to 20 then everything looks ok except zoom bar is not shown...

Some more attachments about rotate at 10 fps (have to wait aprox 10 seconds that it looks like with 20fps instantly)

This also happens with other submenus at 10fps

It looks like vid_get_bitmap_active_buffer is not implemented for this port, so you will sometimes see old bitmap data.

My fault.. new version attached.

@frojnd
You don't need to copy patch file, patch file is for source code.  Just unzip ixus220_elph300hs-100c-1.2.0-liveview.zip to your sd-card as you did it previously.
