[Qgis-user] Trying to get the wktraster plugin to work

[Maurício de Paulo]

Thanks jorge!
Then I figure it's a bug in the plugin. I wrote the wrong modes. I'm fixing

Hum... I'm going to wait for your responde on the parsing part. If not,
should I parse it on the plugin?
Best regards,
Mauricio de Paulo
