Kim Woelders 207cffb207 Avoid some more undefined behaviors with shifts 2023-01-13 10:55:47 +01:00
NRK e76d9bcf9f PNM loader: avoid some undefined behavior 
`ptr` is a `uint8_t` pointer, which will get promoted to an `int` due to
integer promotion. and shifting a signed int by 24 places could cause
signed overflow which is undefined.

> If E1 has a signed type and nonnegative value, and E1 x 2^E2 is
> representable in the result type, then that is the resulting value;
> otherwise, the behavior is undefined.

for frame counter.

Kim Woelders f756d91c31 TIFF loader: Change default save compression type 
As of libtiff 4.4.0 saving an image with COMPRESSION_DEFLATE will
produce a warning:

 TIFFWriteDirectorySec: Warning, Creating TIFF with legacy Deflate codec identifier,
 COMPRESSION_ADOBE_DEFLATE is more widely supported.

So let's just use COMPRESSION_ADOBE_DEFLATE.

Kim Woelders 31f0935707 JXL loader: Multiframe support 
Does not work very well.
Looks like the time needed to render the N'th frame (from scratch) is
proportional to N, so reasonable performance would require the frames
to be generated sequentially while decoding the image.
