         Pixel-perfect scaling for DOSBox-X

This is a build of DOXBox-X with pixel-perfect scal-
ing made on Windows XP:

      ( https://github.com/ant-222/dosbox-x )

To actviate pixel-perfect mode, make sure to specify
the following settings in the config file, using the
comments for guidance:

   output     = openglpp
   doublescan = false

   #only for Windows Vista and later:
   dpi aware  = true

   # true  for aspect-ratio approximation,
   # false for square pixels:
   aspect     = true

To report any bugs, please provide a screenshot  and
all  entries  in  the  debug  output  starting with:
"LOG: OpenGL PP:". They have the following format:

   [<aw>x<ah>]: <sw>x<sh> (<spar>) -> [<sx>x<sy>] -> <ow>x<oh> (<opar>)

where <aw> and <ah> are the width and height of  the
area the algorithm thinks is avaialbe for magnifica-
tion, <sw> and <sh> the  width  and  height  of  the
source image, <spar> the pixel aspect ratio (PAR) of
the source image, <sx> and <sy> the  calculated  ho-
risontal and vertical scaling factors, <ow> and <oh>
the width and height of the resulting  output  image
after  upscaling, <opar> the output pixel aspect ra-
tio.

The purpose of this reporsitory is to add pixel-per-
fect  scaling to the original DOSBox-X maintained by
Jonathan Campbell:

It will not be maintained as a separate project.
