The **Stamp** script is an attempt at simplifying the process of marking image sequences with useful information such as frame, date, timecode, author, version, name of file, sequence, shot, etc.


====== Usage ======
As of august 2015, the Blender binary has to be downloaded from the [[https://builder.blender.org/|Blender Buildbot]], or compiled from the latest git version, as it includes the Text Sequence used in the script.
Right now, the path to the **blender binary** has to be specified in the stamp.py file, in the ''blender_bin'' variable.

The script is written in Python, and uses Blender for image marking and rendering. The script is command-line only at the moment. To get usage help, type:
<code>python stamp.py --help</code>


===== Template mode =====
A .json template file can be written to speed up the marking process, once a specification has been decided upon. In //template mode//, you have to call the script thus:
<code>python stamp.py --template PATH/TO/TEMPLATE.json PATH/TO/IMAGE.ext [--options...]</code>
Type ''%%--help%%'' to get a list of options you can type. These options are specified in the template.json file, in the following form:
<code>[
    {
        "field": "Plan",
        "value": "P01",
        "position": "BOTTOM-LEFT",
        "size": 15,
        "color": [
            0.0,
            0.0,
            0.0
        ],
        "inline": false
    }
]</code>

You then have to pass arguments to the program according to the template, such as: ''%%--plan P12%%''. **Alternatively**, you can use the ''%%--default%%'' option to use //all// fields defined in the template, with their default values.

===== Metadata mode =====
The **Metadata mode** is similar to the Template Mode, but it uses a json string, passed in command line to the ''%%--metadata%%'' argument, to generate fields. For example, the following string will create an “A text” field and a “Frame” field:
<code>--metadata '[{"field":"A text", "value":"Salut !", "color":[1.0,0.5,0.5]}, {"field":"Frame", "inline":false, "color":"#0137F0"}]'</code>


===== Special fields =====
Some fields have a special behaviour.
  * **Frame** and **Timecode** respectively print the frame and timecode, read from the file name.
  * **Date** prints the specified string, or defaults to today's date in DD/MM/YYYY format.


===== Example template =====
<code>{
    "settings":
    {"resolution":
        [1920,1080]
    },

    "metadata": 
    [
        {
            "position": "BOTTOM-LEFT",
            "value": "S001",
            "size": 15,
            "color": "#FF0000",
            "inline": false,
            "field": "S\u00e9quence"
        },
        {
            "position": "BOTTOM-LEFT",
            "value": "P01",
            "size": 15,
            "color": [
                0.0,
                0.0,
                1.0
            ],
            "inline": true,
            "field": "Plan"
        },
        {
            "position": "BOTTOM-LEFT",
            "value": null,
            "size": 15,
            "color": [
                0.0,
                0.0,
                1.0
            ],
            "inline": false,
            "field": "Frame"
        },
        {
            "position": "BOTTOM-LEFT",
            "value": null,
            "size": 15,
            "color": [
                0.0,
                0.0,
                0.0
            ],
            "inline": true,
            "field": "Timecode"
        },
        {
            "position": "TOP-LEFT",
            "value": "today",
            "size": 15,
            "color": "#00FF00",
            "inline": false,
            "field": "Date"
        }
    ]
}</code>
