Hi Peter,
Can you give me an example of how to reproduce the problem(s) you are
seeing? I've just created a 20 MB qxl.win with no problems. (So far!)
Unfortunately not right now, and my memory is vague. I think that
all issues were gone with 16 MB and less. My next image size step
was probably 32 MB, not just 20 MB.
It could be, that just recompiling the latest qxltool source with an
up-to-date compiler and library makes the issues disappear.
I've created a couple of qxl.win files (at coffee time - I'm working)
and checked them with my own QXLWin program. The headers looks strange
to me:
On the 4 MB I see these dubious fields:
* Sectors per map = 21
* Number of maps = 100
* Root directory length = 58
On the 20 MB I see these dubious fields:
* Sectors per map = $A1 (161)
* Number of maps = 100
* Root directory length = 58
I've had a quick look at the definition of a QLWA header in the code and
it appears slightly broken. Some of the fields I would think essential
are not being used - sectors per block for example. That changes as the
files grow bigger and might be related to your problems.
I'll see what I can do - there are still quite a few compilation
warnings I need to get rid of first.
Cheers,
Norm.
