The workaround for ldglite is to get lpub to pass a background

I suspect the same would work for ldview.

This is up to the respective programmers of LPub, LDView and LDGLite, to which
we owe so much!

Thanks.

For reference, Don (the person you're responding to) is the LDGLite programmer.
Also, unless somebody comes up with some brilliant idea, I don't think the halo
problem can be fixed in LDView or LDGLite.

I have finished a few things:

  1. Syntax checking on LPUB meta commands.  LPub stops, shows you the file, the
line number, the failing portion of the line, what was expected, and the entire
failing line.

  2. Regularized LPUb syntax (ony a few small changes)
  3. Routinized step packing into one routine used by callouts and multi_step.
     (multi-step can now do HORIZONTAL and VERTICAL, like callouts).
  4. Translated some silent ignorings into error messages.
  4. Added test cases to my regression suite.
  5. Testing.

Things I need to debug:

  1.  Support for negative margins in pack_steps.
  2.  Philo's "file not found" issue with callouts and multi_step.
  3.  Jaco's "disable PLI" issue.
  4.  Windows 98 with LDView.

Things I want to add:

  1.  Background color for LDView and LDGLite.
      A.  This is easy for assembly images
      B.  LPub tries to help light colored transparent parts with white
background, by providing a darker background color.  I may have to toss
this.....

LPub could oversample images without antialiasing, and then reduce their size,
but I have no idea what algorithm to use for the reduction.

(...) The Delphi library Graphics32 ((URL) can probably be used by C++Builder too. It contains lots of routines for graphics processing, for example downsampling. You can explore different methods there. (19 years ago, 10-Jun-05, to lugnet.cad)

(...) I would suggest (at least initially) to keep it simple. Only support reduction by a factor of two, and then simply average each group of 4 pixels. This should produce a dramatic quality improvement, and be very easy to implement. --Travis (19 years ago, 10-Jun-05, to lugnet.cad)
