SDL 2.0 would be useful too.

Note that we've been using SFS instead of FFS as our main FS for perhaps a decade or so. FFS is usually only needed for interacting with classic AmigaOS floppies and HDs.


I didn't reed the post correctly, shame on me.

Yes, FFS is buggy.

What could users like me do about it:

1. Setting up a bounty for fixing FFS

This sound logical but you can't fix something complicated like a file system, without reproducing the errors. A coder would at least need some 'broken' filesystems for propper error analysis.

2. Setting up a bounty for FFS salvage tools

Maybe if a coder knows how to deal with existing errors, he could try programming a salvage tool for FFS. Something that might help deleting defect files or directories.

3. Switch to a file system from another OS.

Maybe the coders should look for proven file system used on other OSes, like Linux, BSD or MorphOS. This could fix a lot of FS problems and might be necessary for future enhancements of AROS anyway.

buffer[offset] = (UBYTE)((val >> 24) & 0xFF);
buffer[offset 1] = (UBYTE)((val >> 16) & 0xFF);
buffer[offset 2] = (UBYTE)((val >> 8) & 0xFF);
buffer[offset 3] = (UBYTE)(val 0xFF);


well I would recommend unions:

union 
{
   
unsigned long;
   
unsigned char byte[4];
ARGBlong2char;


  
ARGBlong2char.long val;

  
buffer[offset++] = ARGBlong2char.byte[0];
  
buffer[offset++] = ARGBlong2char.byte[1];
  
buffer[offset++] = ARGBlong2char.byte[2];
  
buffer[offset++] = ARGBlong2char.byte[3];

// or better

union 
{
   
unsigned long;
   
unsigned char byte[4];
ARGBlong2char[buffersize];



There are two simple reasons for the use of union here:

1st
The compile can ddecide if he uses '>>' together with '& 0xff' ore something better for the byte access.

2nd
You can switch to other byte orderings faster without thinking where to shift what ...

When you say color reduction, do you mean color quantizing, or alpha reduction such as 32 bit to 24 bit?


I do not remember the exact problem I was working on.

It had to do with colour reduction (24Bit -> 8Bit) I needed a simple and fast algorithm something I could figure out in an afternoon.

First I reduced the 24Bit Pictures to 16Bit, because making a histogram for 65328 colours is much easier than doing it for 16777216 colours. And together with this histogram, I figured out what palette would be good enough for a 256 colour display.

BTW.:

When processing IFF Files you should do it with a state machine, when I started doing it I thought all the date will have the same data chunks coming in the same order, but this is not always true.

Be careful, some programs generated 24Bit IFF pictures with 8- Bit transparency but did not call them 32Bit IFF.

For a simple conversion algorithm I converted the 24Bit to 16Bit where I could easily count the colours for further colour reduction.

Thanks for your work.

A good working distribution is really important.

Please bring Folio to AROS

It is also running on 'other systems' like AOS4 ...
