| Description: |
This file contains changes that implement a "raw" -smooth method (as described in TIP 168) for canvas items. It also does some cleanup of terminology in comments to specific functions. Affected files are tkTrig.c, tkCanvUtil.c, and tkInt.decls. | |||

(Fixing up the documentation and the handling of the smoothing method names was... interesting...) lars_h added on 2004-08-14 17:46:25: Logged In: YES user_id=938835 It lacks the detail of changing the name (as reported by [$canvas itemcget $item -smooth]) of the traditional smoothing method from "bezier" to "true". I wasn't sure how to implement that. One way is to add a special case in TkSmoothPrintProc and still call it "bezier" in the declaration. Another way is to change the declared name to "true" and add a special case for the name "bezier" to TkSmoothParseProc. Related is the matter of how the "raw" method should be registered. The patch _doesn't_ register it, but implements it as a special case in TkSmoothParseProc because I couldn't spot a point where one could make such a registration. There is a comment about this in the patch (last block). IMVHO the least confusing approach is to have a bunch of special cases in TkSmoothParseProc, even though that would be somewhat inelegant. dkf added on 2004-08-13 19:10:32: Logged In: YES user_id=79902 Is this a *complete* implementation of the TIP? lars_h added on 2004-01-28 21:47:58: File Added - 74995: rawCurve.patch | |||
