State of SVG importer
Hello, What is the state of the SVG importer regarding the standard. Can it parse all the specification to be capable to import any kind ofg SVG graphics? Thanks Hilaire -- Dr. Geo http://drgeo.eu

You should try and help on that one. I know that we are parsing more than the equivalent in VW (CADE people of thales) but may be some part are missing. A while ago arcset were missing and igor added it also at the athens level. Stef

To be precise, the missing part is elliptical curve segments. and its still missing. On 28 September 2013 16:35, Stéphane Ducasse <stephane.ducasse@inria.fr>wrote:

For example, does this small attached SVG works ? Hilaire -- Dr. Geo http://drgeo.eu
Nope.. and needs to be fixed. I would nice if you (or anyone willing to) could help with finishing the importer. You can find svg package in athens repository: http://smalltalkhub.com/#!/~Pharo/Athens [image: Inline images 1] On 29 September 2013 18:51, Hilaire Fernandes <hilaire.fernandes@gmail.com>wrote:

I manage to load the needed package by hand. But there is a missing class AthensCairoSurface. Please could you check on a fresh pharo 2.0 the configuration and fix it? Thanks Hilaire -- Dr. Geo http://drgeo.eu

I think that we should work on pharo 30. We do not have the resource to maintain it on 20. First it should work on 30.

Hilaire I published a new baseline - to address SVG needing XMLParser - added version 24 to use the new baseline (no change) - added version 25 to load all the more recent versions from the repository. So let me know if this is helping you. Normally 24 should load ok I'm testing. â¦. It looks some packages were changed in the image and should be merged and published. Igor should do that but he is lying sick in his bed. Stef On Sep 30, 2013, at 1:27 PM, hilaire <hilaire.fernandes@gmail.com> wrote:

thanks for help. Yes, i need to create a new configuration version, since there's some most recent work which committed but not yet adopted inside of config.
Igor should do that but he is lying sick in his bed.

yes, i don't remember all the details, but it should be easy to fix. i stopped working on it, when realized that the missing elliptical segment type prevents me to display correctly many svg content, so i started working on it but this still not there. it needs some overhaul in path creation, and calculating path geometry.. i wanted to extend functionality , so you can use own parametric functions for path segments (elliptical curves is just simple case of this). The problem is that Cairo don't have direct support of elliptical curves, so they need to be approximated either by bezier curves or by straight line segments (a tiny ones, of course). This is where i stopped in May, because i had to focus on text rendering & text editor, and as you may know i still working on it..

Igor I'm adding development: spec <symbolicVersion: #development> spec for: #common version: '2.5' stable: spec <symbolicVersion: #stable> spec for: #'pharo2.x' version: '2.1'. "after some modification in NB made it incompatible with 3.0" spec for: #'pharo3.x' version: '2.3' and you should probably merged the version in 3.0/main so that everything loads clean. Stef

yes , there are multiple important updates which made to NB which making current version of Athens incompatible with pharo 2.0. The last version of Athens, compatible with 2.0 image is 2.1. ConfigurationOfAthens loadVersion: '2.1'. and to load svg package use: (ConfigurationOfAthens project version: '2.1') load: 'SVG' (but you need to load XML support first). And since you planning to work on SVG, i recommend you to pick up the latest pharo 3.0 image where athens already installed and work there, on development version of Athens.

Ok I will update the stable setting because it was just loading the development version so breaking the point of stable Igor such information should not be only in your head!!!!

it is work to do.. but i am not sure it is worth doing. Pharo 2.0 officially not supported by Athens, so why we should worry about staying compatible? Yes, in perfect case , configuration baseline should contain branch to load different versions for 2.0 image, and for 3.0. But to do that , first i need to learn (again) how to do it :) We certainly need a UI tool for configurations, because keeping all those "how to-s" in head becomes tedious and counterproductive task.

yes and it is coming, versioner will help us for that. But to me it looks like you did not write enough configurations. I hate writing them but I do not it because there is no other ways to manage quality and reproducibility. If this is the price to pay, I pay it because this is what I want. a ONE CLICK loading system. I take a reference one and I copy. So now this is done. Have a look and see if it loads what you think it should. Stef

I don't remember, how many of them i wrote, but certainly not enough to
remember all things. Most of projects is simple, just plain dependencies, but when things get more complicated like loading different versions for different platform.. this is where usually you need to open manual and read it over again :)

I will have a look now I would not add it to Athens but create an SVG importer Configuration since SVG is not linked to athens per se. Do you want me to do it? Sef
