It's probably going to be close to that. Bbyak had already been working on such an additive and subtractive options for the calligraphic tool. There's a bit of a difference in some use cases, and it will be diverging more. From what I can see of things, though, the calligraphic tool will be very useful for a different set of operations. > An other thing; it would be really cool to be able to auto switch > to the eraser tool when using the eraser of a wacom tablet. Eeek! You got me! :-) Actually with the code in SVN it should be able to do almost that already. It should be detecting input devices and switching to the last tool used with a given device (tablet mouse/puck, stylus front, eraser back), so once you use the eraser end and use it to pick the eraser tool, it should switch tools as you go. I've just not tested that again recently since I'm on my box running Hardy and that has some wacom issues. And thanks for reminding me. I'll make that tool the default for any "ERASER" type extended input device.

Inline Function Removal
by Jimmy 28 Apr '08

28 Apr '08

I am currently working on Inline Function Removal and while replacing calls to sp_repr_set_attr with direct calls to the wrapped member functions I noticed that the wrapped function is defined as void. There are tests that are run to check if sp_repr_set_attr fails. sp_repr_set_attr always returns true although I suspect this was designed to change at some point If sp_repr_set_attr is replaced in one of these tests for example: /// \todo fixme: Exception if object is NULL? */ if (!sp_repr_set_attr(object->repr, key, NULL)) { No value will return and the compilation will fail. Should I just comment out these tests or remove them and leave the todo? As of now the tests just accept true from sp_repr_set_attr and they don't actually check anything. Jimmy Varvaro

[Fwd: Inkscape Freshmeat Page]
by Ted Gould 28 Apr '08

28 Apr '08

Hey, Who was editing the Inkscape Freshmeat page? I created it, but I don't seem to remember my login. I'll recover that, but I thought someone else could edit it, I haven't updated it for a while. --Ted -------- Forwarded Message -------- From: Rygle <pittos@...1208...> To: ted@...11... Subject: Inkscape Freshmeat Page Date: Mon, 28 Apr 2008 13:26:38 +1000 Hi Ted, Don't know if you've noticed that the Freshmeat page doesn't yet mention 0.46. You're down as the author of that page and I can't change anything. Cheers, Rygle

NEW: Filter Effects
by Ted Gould 27 Apr '08

27 Apr '08

Hey, So I subclassed the effects to provide an easier way to just add filters on a group of objects. Hopefully bringing this into the realm where anyone who understands the filter dialog could build their own filter effect. It needs to documentation and overall is less than complete, but I thought I'd put it out there for people to play with. I took all the examples from Mauve's excellent example file[1] and turned them into effects on the effects menu. Now you should be able to just grab and object and apply these to your objects. To create your own I suggest copying "sepia.h" in /src/extensions/internal/filter and replacing the strings. All you need is a non-translated name (ID), Menu name, description and then the filter that you want to apply. You'll then need to add it to "filter-all.cpp" but that is also pretty straight-forward. If someone isn't faster, I'll make better docs. [2] It is a little more difficult to use parameters, but not that hard. There is one example of that, drop shadow, which of course works with live-effects also. I would also like to clean this up and make it easier. The biggest limitation of the implementation right now is that it will ONLY apply if there isn't a filter on the object currently. Long term, I'd like it to merge the filters. That's all for now! --Ted [1] I didn't take Drop Shadow from there because I was looking at the SVG file and the filter for Drop Shadow is above the linear gradient where I started looking, so I missed it. No seriously, stop laughing. [2] I would like for someone with a light programming background to do this as they're likely not to skip over things that other people would need to get started.

Buildtool -- new "continueOnError" flag
by Bob Jamison 26 Apr '08

26 Apr '08

Johan asked me to look into a way of having buildtool continue processing files after a compile error happens on a file. Although going to the next task after a failure would be incorrect, there is nothing to stop us from letting the <cc> task continue processing its file list after a compile failure. So now there is a new attribute for <cc>: continueOnError="true" which will allow the <cc> task to proceed with its file list after an error. At the end of processing the list, it will return failure as before. If you want to use this feature, just set the flag to true, and read the "compile.lst" compiler listing file after buildtool is done. By the way, everyone should read compile.lst occasionally, even when builds are successful. Warnings are listed there. bob

Toolbar icon sizes
by Jon A. Cruz 26 Apr '08

26 Apr '08

The preferences for the toolbar icon sizes has been changed from a simple toggle of two sizes, to a combo to allow for three sizes. Also, all three toolbars are now configurable. This fixes a problem many users, especially Ubuntu users, were seeing on monitors that only went to 1024x768 or smaller. Things should not affect anyone's existing preferred setup, and should take manual intervention to see a difference in the UI. Give it a bit of a shake-down and see if there are any problems with settings, etc. Thanks. p.s. yes, I did get the release notes updated also. :-)
