Devanagari label encodings and fonts generated are not being rendered #6

Open pankajverma04 opened 9 months ago

pankajverma04 commented 9 months ago

I am using this tool to generate encodings and fonts as well for Devanagari labels. The generation for both were successful but were not being rendered. Steps followed :

  1. Building and running docker image in the root directory. 
    docker build -t positioned-glyph-font .
docker run --rm -it -v "$(pwd)":/root/ positioned-glyph-font
  2. In container : 
    cd raqm/
./run.sh

    raqm/labels_requiring_encoding.json used is as follows :

    [
"Rafi Ahmed Kidwai Marg",
"रफी अहमद किदवई मार्ग",
"Janpath",
"जनपथ",
"Vijay Chok", 
"विजय चोक",
"Rajpath",
"राजपथ",
"Raisina Road",
"रायसीना सड़क",
"Motilal Nehru Marg",
"मोतीलाल नेहरू मार्ग",
"Kumaraswami Kamaraj Marg",
"कुमारस्वामी कामराज मार्ग",
"Rajaji Marg",
"राजाजी मार्ग",
"Teen Murti Marg",
"तीन मूर्ति मार्ग",
"Ashutosh Mukhejee Road",
"आशुतोष मुखर्जी रोड",
"Sarjapura Road",
"ಸರ್ಜಾಪುರ ರಸ್ತೆ",
"Inner Ring Road",
"ಇನ್ನರ್ ರಿಂಗ್ ರೋಡ್"
]

    Generated label mapping is as follow :

    {

  3. Then run ./run.sh in the font-maker directory, which generates fonts.
  4. Created a new directory in examples similar to already available examples with changes in style.json and index.html and add newly generated fonts.

The web page did not render the labels and displayed nothing.

Oh sorry I need to clean this up a bit. I think you are using an outdated path. Will get back to you

wipfli commented 9 months ago

@pankajverma04 I updated the main readme. Can you have a look at it and follow the steps?

Main changes: removed the raqm folder, and added a http server which you can request to encode labels.

wipfli commented 8 months ago

Let me know if the new instructions and scripts work for you @pankajverma04
