Aiming for new release

[Neon22]

Thanks to covid lockdowns for the time to work on this.
Always bothered me I could not use this module with handweaving.net sample wif files.
Finally tracked it down.

There are lines missing in the WARP and WEFT COLOR sections which the spec says if not supplied should be using the default as defined (optionally) in the COLOR param in the WARP or WEFT section.

I am working in 3.9.7 FYI and all looking good so far.
Addressed in Pull Request #4

[Neon22]

Added ability to ignore extra treadles in Tieup. Some files include full treadle plan even though the draft uses only the first few.

Added ability to load the Author etc metadata as well as Notes. Made available via stats command
Also added Source program and version - but not currently propagating to json file as maybe its now this program which is generating them. Especially if a wif file is saved eventually.

[Neon22]

The branch grows:

• added reading of spacing from wif file and storing in weft and warp classes ready for render.
• made round trip of wif -> json -> wif to work with spacing and in general
  • e.g. wif was writing in binary, now ascii
  • json now utf8
  • reordered wif export to get Wif at head followed by Contents

[Neon22]

Added Tartan and twill generators to pyweaving menu. more changes coming here with render options and stats.

Also outfile will use directory from infile if no directory defined in outfile.

[Neon22]

Added ability to load wif files with liftplans. They were getting in but not rendering. wif reader adjust to pass liftplan setting in.

Started on render renaming for clarity but these changes totally superseded in next commit

[Neon22]

Fairly large set of changes.

1. Color class modified for wider use and can load Colors as well as tuples.

   • hex property added for svg target later

2. Found problem where warp thread colors and drawdown were reversed horizontally. The Threading section was correct. Turns out this problem is invisible if the draft is symmetric.

3. Large number of changes. Added a Drawstyle class - this defines the layout, spacing and flags different modes of showing the draft,

   • E.g. can have solid or blob markers, or use the thread color (will add numerics next)
   • can toggle visibility of line markers (ticks)
   • can adjust gaps between elements

More coming to try to maximise info that can be extracted from a wif.

4. Show floats as an option - not yet in the command line but can be selected by modifying the Drawstyle class defaults in init manually

[Neon22]

Add fix to get liftplan option back into render (still only png)

Also enhanced tartan generator to use the STA styles and deal with mirrrored and asymmetrical as wel as rectangles with sep warp and weft counts.
Setup for Z and S twill but not propagated through yet

[Neon22]

Major refactor too make all sections have a startpos and return an endpos.
Can now rearrange layout.

[Neon22]

Exercising the refactor to add a Title to the top of the draft

[Neon22]

Added spacings to renderer. now can render warp and weft with variable spacing.
I need a few more samples to ensure its all good.

Two styles - "Clarity" where a progression of larger boxes for larger threads.

• and "Accuracy" for later which will try to use the thread ratios more accurately and force solid mode as boxes too small for text.

two pass approach - finds all the spacings and fill sin defaults, finds ratios, determines box sizing and then stores on each thread as yarn_width iv.

• then uses yarn_width when drawing each section.

[Neon22]

Added Prelim satin generator. Calculates the satin numbers for regular satins. Not yet doing the two irregular ones 4,6
Also not yet drawing drafts.

[Neon22]

Added ministats section under title with summary of warp,weft,yarns, floats, warp/weft balance
Also heddle counts on LHS of the Threading. Listing number of heddles need for each shaft.

[Neon22]

somewhere render without an outfile stopped working - fixed.

[Neon22]

Updated the twill generator to take a shape string instead of a 2/2, 3/3, etc

So can do a 1/3 or a 3/2 or a 3/2S for an S shaped twill
Can also combine complex twills.
E.g. 1/3 2/2 3/1 1/1 will make an 18 shaft/treadle twill

Z is the default if no suffix on end of shape string

One day will add points, staggers, etc in eth threading section instead of a straight draw.

[Neon22]

A few changes to support faulty wif files from various vendors.
Also twill generator almost same as Tartan.
usage: pyweaving twill [-h] [--render] [--renderfile RENDERFILE]
[--renderstyle {solids,blobs,colors,numbers}]
shape outfile
where shape is something like "1/3 2/2Z" and "--renderfile auto" will autoname based on wif and put in same dir as wif.

Some refactoring and comment adjustments

Float length now correctly being presented. (was short by 1)
Added Floating selvedge detection into ministats section.

Found neat trick used by Fiberworks to embed creation date into TEXT section as a comment.
Will probably use/maintain ourselves.
Required changes to RawConfigParser to read/write comments

[Neon22]

Added Notes section under drawdown.
If some notes then they are printed there under a heading.
Last line is added if notes exist which indicates the source program and version
