[Plplot-general] cmap0 file format

[Thorsten B. <tho...@do...>]

Hi!

I'm new to this mailinglist. I've started studying/using Plplot because we
want to use Plplot within some of our software and I'll be the one to
implement it.

I've already installed Plplot (version 5.9.7) together with all necessary
tools (CMake, in this case). I was then able to build PLplot and compile
the examples. So far, so good.

Development of our software currently is in Ada (and will stay in Ada as
long as I'm to develop it). The OS used is Windows (in different flavours,
currently I'm working on a Windows 7 machine).

When running all examples as well as some other test programs of mine, I
always get this error on the console that opens when starting a program:

---snip---

*** PLPLOT WARNING ***
Unrecognized cmap0 format data line.  Line is #000000

---snap---

Also, the background color is always white, while all drawing (even if
explicitly setting a pen color) is done in red.

I read this thread (
https://sourceforge.net/mailarchive/message.php?msg_id=24879301 ) but
although it seemed to be the same problem, it was not (but may be
similar). I also read all the online documentation, but found no format
description of the cmap0_default.pal file.

I'm sure the file is found and read, because when I edit the file
cmap0_default.pal, I can achieve better (and seemingly correct) results.
I've added an additional "column" after all the color definitions in the
cmap0 file. It currently looks like this

---snap---
16
#000001 0
#ff0000 0
#ffff00 0
#00ff00 0
#7fffd4 0
#ffc0cb 0
#f5deb3 0
#bebebe 0
#a52a2a 0
#0000ff 0
#8a2be2 0
#00ffff 0
#40e0d0 0
#ff00ff 0
#fa8072 0
#ffffff 0
---snap---

Et voilà: There is no error/warning output done to the console and the
background is black, while drawings are done in red (or any other color,
if explicitly setting apen color).

To me it looks as if the format of the cmap0 file has changed, but this
change is not (yet) reflected in the cmap0 being delivered.
