[SVG Renderer] SVG rendering in Draw AGG

shadwolf 30-Jun-2005 [51x14] | then construc path to get data then translate this data to a draw equivalent exploitable datas |
and fill the draw block with this data | |
my point is to make a recursif capapble code | |
for example my object is set into xml global variable | |
I I want to interrogate the first shape description on the top level ( out of group blocks) I have to build a path like that xml/svg/path/1/d | |
or maybe build the path xml/svg/path then attribute to a temporary var the foreach ob xml/svg/path [ ob processing ] | |
so to build the path we start xml/svg "/ " g or path if g we seek 3 thing transform field and path field or sub g field | |
I give you the code maybe this will be more clear | |
shadwolf.free.fr/svg-demo-shad04.r | |
oups sorry | |
wrong adress | |
http://shadwolf.free.fr/svg-demo-shad03.r | |
in this file we have xml-to-object function load-svg function (mostly empty there is where to put the data conversion and draw block construction) and the widget that start the program | |
and the windows where the draw block is shown | |
shadwolf 1-Jul-2005 [65x2] | I solve this issue regarding object retriving information I will enhance this pont to make it recursif retriever |
at this point code have not drastically change ... like 40% is the same code | |
shadwolf 2-Jul-2005 [67x13] | *************** |
I'm still working full time on the S VG renderer. I'm close to be at the same level than the previous code but as I'm working with objects the code seems to be more fast ... | |
the recursivity treatement for g block are also easier to do | |
I still not soleve my matrix problems so until now I don't implement it into the actual code | |
I don't know how to treat linearGradient too | |
hum xpdf.svg file shows me a problem with the use of xml-to-object ... if you have serveral g block at the same level all g block are compacted into the same reference | |
so in Rebol tree object the g block can be a bloc of sub object or an object ;) | |
*********** | |
Okay so here is the first version of my work on SVG to rebol objects tree structure | |
http://shadwolf.free.fr/svg-demo-shad04.r | |
try to load all the files that Ashley provides with his svg-demo | |
this script support recursive G block (objects /list) and path (object list) | |
what is not supported are radial / linear Gradient (content and border), transformations (local/global I'm still pending for informations on it) and all other shapes than path (like rect for example) | |
Ashley 2-Jul-2005 [80x2] | Good progress! If you change: "stroke-width" [line-width: to decimal! val] to "stroke-width" [line-width: to-unit val] then it'll run all your sample SVG icon files as well. Wish I knew the answers to your AGG questions, but like you I'm waiting on more documentation / examples. |
I've spent quite a bit of time looking at Inkscape (http://www.inkscape.org/) and it seems to be the only / best SVG game in town (their command-line driven SVG to PNG conversion seems to be particularly well regarded). Looking forward to their 0.42 release as it supports OS/X as well. The Clip Art site that they link to (http://www.openclipart.org/) is also a treasure trove of Public Domain files (which solves the GPL concerns I had with many of the dedicated KDE / Gnome icon sets). I'm also looking forward to their release 15 which seems to be just around the corner. Lots of good news in the SVG world, I wonder how long before mainstream browsers start supporting it? (without plugins). | |
shadwolf 2-Jul-2005 [82x7] | Inkscape is the successor project of sodipodi (for example you can see reference to sodipodi into teh SVG output files ...) Sodipodi was abandonned by the dev team so some of them retakes it and continue the adventure with inkscape |
All this to say that it doesn't fall from the sky ;) | |
I like particularly the capability of generating light weight SVG files (plein text) the drawing tools are simple powerfull very well thinked and pretty good | |
I psent lot of time using it (more than 80 hours since this last weeks ) all SVG files that I could found exists | |
I like the XML primitive draw explorer like a tree view of the compoun of your draw this is particularly good to write SVG renderer | |
Handling SVG as REBOL object! tree makes it really really easier to set recursivity and code writing ( as all can be exploded into small fonctions I hope the resulting code once terminated won't be so deficult to read | |
but you know now my way to work I prefer easy and powerfull /flexible code than hudge monolitic code ;) | |
Ashley 2-Jul-2005 [89] | No argument here. ;) |
shadwolf 2-Jul-2005 [90x4] | http://shadwolf.free.fr/svg-demo-shad04.r |
now supports rect tag ;) | |
oups I make it only for groups ;) | |
hahaha ;) | |
Graham 2-Jul-2005 [94] | Firefox is supposed to be able to support SVG ( a subset at least ) without plugins, but I couldn't get it to work. I had to download Adobe's plugin. |
shadwolf 2-Jul-2005 [95x3] | so we can see in my code 2 approch for retrieving information one for top level second for g tags (groups can be recursiv) |
GRaham same for me adobe plugin works well with IE but not with firefox | |
maybe they saw a boggus open door in this plugin and disable it's support (this can be the case for a 1.0.4) | |
Graham 2-Jul-2005 [98] | I got the Adobe plugin to work with firefox eventually. |
shadwolf 2-Jul-2005 [99x2] | so you have to remaining choice (3 in fact ) 1) using IE but then your not my pal any more, 2) installing Inkscape and relate it to svg file 3) help me finishing the SVG viewer using REBOL !!! ;)) |
but what I need are high level information and formation on draw agg and this I know very little people that can respond in this point :) | |
