Playing with Odoo and Tesseract.

During these lasts days i have been reading things about Odoo and how it had improved since i last worked on it professionally and i came across  Basics-developing-simple-module-openerp a great resource for anyone wanting to start working on Odoo.
So work started on document_scanner, a plugin for Odoo, which uses Tesseract to import pictures and convert them to text .

 The entry point of a Odoo plugin is the __init__.py file and as my plugin is written on document_scanner.py my __init__.py file looks like

1 2 3

# -*- coding: utf-8 -*- import document_scanner

Next lets take a look at the __openerp__.py file where you must include the dependencies, the description and your personal information which will be visible to the user when the plugin is installed. My file looks like:

1  2  3  4  5  6  7  8  9 10 11 12 13 14 15

{     'name': 'Document Scanner',     'version': '1.0',     'category': 'Tools',     'description': """ Module which uses OCR to treat image files in Odoo. ==============================================     """,     'author': 'Rui Caridade',     'depends': ['base','document'],     'data': ['document_scanner_view.xml'],     'demo': [],     'installable': True,     'auto_install': False }

which visually translates to

On the __openerp__.py file if you notice there is a reference to a xml file "document_scanner_view.xml" which is where the look and feel of the plugin is defined.
On document_scanner the xml file looks like :

1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

<?xml version="1.0" encoding="utf-8"?> <openerp>     <data>         <record id="document_scanner_wizard_view_form" model="ir.ui.view">             <field name="name">document.scanner.wizard.form</field>             <field name="model">document.scanner.wizard</field>             <field name="arch" type="xml">              <form string="Document Scanner">                 <group col="4">                 <field name="data"/>                 </group>                 <group col="4">                     <field name="textoDaImagem"/>                 </group>                     <button name="import_file" string="Import" type="object" />                     <button icon="gtk-cancel" special="cancel" string="Cancel"/>             </form>             </field>         </record>              <record model="ir.actions.act_window" id="action_document_scanner_form">         <field name="name">Document Scanner</field>         <field name="type">ir.actions.act_window</field>         <field name="res_model">document.scanner.wizard</field>         <field name="view_type">form</field>         <field name="view_mode">form</field>         <field name="target">new</field>     </record>              <record id="action_dir_doc_scanner_view" model="ir.actions.act_window.view">         <field name="view_mode">form</field>         <field name="view_id" ref="document_scanner_wizard_view_form"/>         <field name="act_window_id" ref="action_document_scanner_form"/>     </record>     <menuitem         action="action_document_scanner_form"         id="menu_document_scanner"         parent="knowledge.menu_document_configuration"/>     </data> </openerp>

To better understand the file i recommend you read it from the menuitem till the top.

After that was done i needed to find a picture to test and i found Factura Vaca

The end result

 
The text is not quite right yet, still have to look into it. Still thinking on how i can improve this plugin. Any suggestions?
