I wrote PettySVG almost a year ago as a minimal SVG renderer framework for Mac OS X. As such it works relatively well, although bugs still remain and the set of SVG functionality supported is rather low (PettySVG might be better suited as a SVG Tiny or SVG Basic renderer).
However today I received an e-mail from Will Thimbleby, who has just released version 1.1 of his drawing program, Lineform. Lineform 1.1 adds, amongst other new features, SVG importing and exporting. This is fantastic news. I had looked at Lineform back when it was still a 1.0 application and found I couldn’t use it mainly because it lacked SVG support.
Version 1.1 also adds support for CoreImage filters. This is full fledged CoreImage support inside a mature and robust drawing tool. Lineform isn’t a toy application that simply lets you apply filters to image files. Lineform is quite possibly a “killer app” for CoreImage and with its addition Lineform could well become an Adobe Illustrator competitor.
What is rewarding to me, is that Will used my PettySVG to help him develop the SVG import/export in Lineform:
It was very helpful in getting an understanding for how NSXML worked and getting started on my own SVG code. [...] In any case you have my thanks for providing the code, it would have taken me much much longer to get to grips with NSXML without it.
I find e-mails (or blog comments) such as this extremely gratifying.
