Metodo standard di importazione SVG

Dall'ultima versione di Synfig (dalla 0.62.02) è presente un'opzione per importare gli SVG dal menù File -> Importa. Questo metodo pare lavorare meglio rispetto al sistema spiegato sotto, tuttavia vi potrebbero essere problemi per importare alcuni elementi SVG correttamente. Vedi questa voce nel forum per alcuni consigli.

La prima importazione potrebbe fallire, riprova con lo stesso file due volte.
La versione 0.62.02 è riportato funzioni meglio in Ubuntu rispetto alla versione 0.63.00.

Altre Opzioni

Le seguenti sono opzioni datate o speciali per esperti.

Opzione 1

Usa un foglio di stile XSLT 2.0 per trasformare un SVG XML in Synfig XML.

Obiettivo

Trasformare una immagine SVG in un file da importare in Synfig. Primo guarda nel foprum: http://synfig.org/forums/viewtopic.php?t=30

Prerequisiti

Assicurati che un ambiente di esecuzione di Java sia installato (JRE-Java Runtime Environment).
Prendi una versione recente del processore SAXON XSLT per Java da http://saxon.sourceforge.net/. Versione raccomandata: Saxon-SA 9.0 (saxonsa9-0-0-2j.zip).
Estrai il pacchetto SAXON in una cartella a tua scelta. Ad esempio in d:\saxon come di seguito. La cartella conterrà moltifile JAR.
Genera il file d:\saxon\svg2synfig.xsl con il contenuto fornito in basso nel documento ([[#svg2synfig.xsl|]]).

Prerequisiti opzionali per Windows

Se non vuoi usare la linea di comando, crea un file batch d:\saxon\svg2synfig.bat con questo contenuto:

@java -jar %0\..\saxon9.jar -xsl:%0\..\svg2synfig.xsl %1 > %0\..\synfig.sif
@pause

Trasformazione di un SVG in un file Synfig

File Batch Windows

Trascina e rilascia il file SVG sul svg2synfig.bat.

Linea di Comando

Spostati in d:\saxon.
Inserisci il seguente comando (sostituisci your_input.svg con il percorso del file SVG):

java -jar saxon9.jar -xsl:svg2synfig.xsl your_input.svg > synfig.sif

Risultato

Se la conversione ha avuto successo, il risultato sarà scritto nel file d:\saxon\synfig.sif. Puoi aprirlo in Synfig.

Limitazioni

Sembra non funzionare con SaxonB (versione FOSS)
SVG compressi (svgz) devono prima essere decompressi.
Solo oggetti percorso di SVG path sono supportati. Prova la conversione di tutti gli oggetti per i percorsi.
Un solo sottoinsieme di percorso elementi è supportato. Prova a modificare tutti i percorsi nodo per avere tangenti suddivise, e tutti i segmenti percorso per per curve.
Colorazioni complesse(es.: i gradienti) non sono supportati.
Solo le trasformazioni di base sono supportate.
Riempi e controno sullo stesso oggetto non sono supportati.

Opzione 2

Questo è un programma in C di akagogo che usa libxml per convertire gli SVG nel formato di Synfig.

http://none.carlos.googlepages.com/svgtosif.zip

Installazione

Esegui il solito ./configure && make && sudo make install

Utilizzo

I file SVG necessitano si essere in una cartella chiamata data. Devi eseguire il comando dalla cartella genitore, ma usando il solo nome del file come argomento per il comando. Così se:

Se sei nella cartella "/esempio" devi creare una cartella di nome "/esempio/dati" e copiarvi dentro il file "file.svg".
Ora esegui svgtosif file.svg quando hai ottenuto "/esempio" come cartella di lavoro corrente.

COme vedi, non è propriamente amichevole. Per risolvere rapidamente, usa il seguente script bash:

#!/bin/bash
mkdir data
cp "$1" data/
/usr/local/bin/svgtosif "$1"
NAME=`echo "$1" | cut -d "." -f 1`
cp "data/$NAME.sif" .
rm data/*
rmdir data
echo "Conversion complete!"

Metti questo codice in un file di nome "svg2sif" (nominalo come vuoi, ma non nominarlo "svgtosif") e ponilo in una cartella PATH (suggeriamo /usr/bin). Poi:

chmod +x /usr/bin/svg2sif

E' tutto. Ora usa:

svg2sif <file.svg>

ed otterrai un file .sif nella cartella in cui lavori.
