using unfolding maps

divya191

Hi all

I am new to processing, and am trying to create a map which will get mark certain locations on it based on the coordinates it gets from a csv file. I am trying to create the map using the unfolding maps library which runs only in processing 1.5 and not 2.0.

I checked and I saw that there is no function to read a csv file in processing 1.5. Neither is there a function to read a json file.

Any help regarding how I can read my data to create the markers would be great.

Either you gotta code 1 yourself, or try to insert the 1 from Processing 2:

https://github.com/processing/processing/blob/master/core/src/processing/data/Table.java
https://github.com/processing/processing/blob/master/core/src/processing/data/TableRow.java

Perhaps splitTokens() might be enough?

In 1.5, people just used split() to read CSV data. And used the library from json.org (or more elaborated libraries like Jackson) to handle Json data.

Thanks all. I managed to read the data in .txt format using loadStrings and converting and converted the coordinates from string to float.

bckmnn - Thanks a lot. It has to be a new release. I checked the site yesterday itself. It wasnt there then.
