Vertical Displacement of line text about mapnik

[artemp]

[gravitystorm] This was made possible by [493] about five months back, but the text positioning is often sub-optimal, with characters overlapping one another and other positioning artefacts.

For example, see the attached file with three examples of the number 16 written with a dy = '5' on the TextSymbolizer. The first is correct on a straight line, the second exibits excessive spacing between characters, and the third shows characters badly overlapping.

[dave] I've changed how displacement is done in the r597, now the same angle of displacement is applied to the whole string, instead of on a per character basis.
Example: [http://trac.mapnik.org/attachment/ticket/38/fix_1.png]

Test and give some feedback :)

[springmeyer] Andy,
Have you had a chance to test and comment? Is Dave's r597 working for you?

[springmeyer] noting here that Ticket #71 requests a related feature - line offsetting (in addition to text offsets)

[gravitystorm] I think this bug can be closed - it's been implemented and used extensively in the cycle map for a while now.
