Custom Jigsaw Shapes
Any bugs or unintuitive user UI alerts most appreciated
One of the limitations of the pre v2.20 Jigsaw Solver was the fixed set of box 'shapes' available. Other publishers invented other mappings but the solver was not accessible to them. Now you can start from scratch or from an existing shape and design a new one. The new mapping is passed directly to the solver engine rather than an index to the fixed list.
The "custom" shape can be selected from the end of the example list.
If you have never created a shape this will be all one colour number. If set up correctly and sent to the solver it should save as a cookie and load if selected in the future.
However a better way to start is to click on [Enter New Jigsaw] or [Modify this Jigsaw].
You can also [Import] a jigsaw shape map - this consists of a string, 81 characters in length, containing only 1 to 9.
As you edit the shape blocks a counter of all the cells of each colour will be maintained at the top. You need to get each number to be "9".
This is also where you select the current colour to click with
The blue bent arrow button is for rotating the whole scheme.
This is a quick way to create a test custom shape - take an existing one and rotate it. When you [Send to Solver] the board will be emptied. To set a test puzzle for an existing shape you will need to grab the numbers of an example puzzle using [Email this board]. But you also have to rotate them the same number of times. I do this in the Sudoku solver since that has a rotate board feature. I import and rotate and email to get the 81 clue string.
Here is an example of a link using "Andrew Stuart 5" and rotated once to create a custom shape.
Here is a link without puzzle numbers - just loading a custom shape (thx Roy Watts)
Hopefully we'll get some real examples of genuinely Jigsaw Puzzles with new shapes very soon.
