Re: [swfmill] Bounding boxes for glyphs bug?
Hello Ralf Sorry for not responding any earlier; I've been busy and lacked the energy to dig into this. I seemed to have trouble building your patched swfmill but today it turns out that I cannot even build the plain swfmill svn. The autogen.sh script spits out a few warnings and error messages and that's it. I'm not familiar with building stuff from svn, so I might be making some rather obvious mistakes here. What version of which tools should I be using? regards Huub From: Ralf Fuest [EMAIL PROTECTED] Reply-To: swfmill@osflash.org To: swfmill@osflash.org Subject: Re: [swfmill] Bounding boxes for glyphs bug? Date: Thu, 14 Jun 2007 21:56:33 +0200 Hello Huub, I changed some things in SWFShapeMaker.cpp in my SVG patch. A quick test showed that the bottom values of 'o' and 'e' in Vera.ttf are almost equal with the patch applied. You can try to apply the patch and check if it works for you. Although I'm not sure if the bounding box calculation in my version is correct, because I haven't tested if the values it produces are accurate. You can download the patch at: http://osflash.org/pipermail/swfmill_osflash.org/2007-May/001274.html Ralf Hello I used swfmill to generate a swf library containing just a few glyphs from a font. Wanting to use swftools to build the final swf animiation I used swfextract to build a font library swftools would understand. Defining textfields containing just one glyph in swftools I found that some of those glyphs would have some parts chopped of. Trying to fix this I uses swfmill swf2xml to look at the bounding boxes in the swfmill output, I changed the values, used swfmill xml2swf and then swfextract again to finally get a correct looking animation. Having used several tools, the source of the issue was obvious of course, but looking at the xml after unsing swfmill swf2xml on a swf file made by swfmill simple using plain old /usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf I found that for instance the bottom of the 'o' was significantly lower then the bottom of the 'e'. Which corresponded with the 'o' being chopped of at the bottom. Looking at the code in SWFShapeMaker.cpp I found that if a CurveTo is include in the shape then only the second point is used to find the bounding box. This does not seem to a problem since in sequences of CurveTo's it seems that the first point of a CurveTo is almost equal to the second point in the previous CurveTo. But the first CurveTo in any sequence does have a first point which is never used to find the bounding box. I added the line minmax( cx+(lastx*factorx), cy+(lasty*factory) ); to the end of SWFShapeMaker::CurveToR and found that the problem was gone, looking at the xml again, the 'e', 'o' and 'u' had the same bottom as they should (I included only a few glyphs). I'm guessing that it would be nice to have that extra minmax call included only in the first CurveTo in a sequence, but I don't know enough about TrueType files to be sure.

Re: [swfmill] Bounding boxes for glyphs bug?
Hello Huub, several people had problems building the svn version recently. Some of this problems were caused by a missing ChangeLog file. I've just fixed this in svn. When this doesn't solve your problems you should provide the error messages generated by autogen.sh.

Re: [swfmill] Bounding boxes for glyphs bug?
Hello Ralf You were right. Compiling now works; patching and compiling works and I can also confirm that my original issue (bounding boxes of ttf glyphs) appears to be fixed. There was just one absolutely negligible difference between the bounding boxes in the file generated by your patched version and the one generated by the version I built myself a few days ago. Maybe just a rounding error somewhere. Thanks Huub From: Ralf Fuest [EMAIL PROTECTED] Reply-To: swfmill@osflash.org To: swfmill@osflash.org Subject: Re: [swfmill] Bounding boxes for glyphs bug?

Hello Roxlu, I have svn access since yesterday. I've already fixed some things in svn and committed the gradient patch a few minutes ago. Ralf Hi Ralf, I was wondering if you already had access to the svn? gr. Roxlu ___ swfmill mailing list swfmill@osflash.org http://osflash.org/mailman/listinfo/swfmill_osflash.org
