I would like to generate an image from a text string stored in the SQL database.
We are currently doing it with another application, but I would like to migrate that into Perspective.
This is one example. Each cell represents one position from the stored value.
No matter what output is, but I need to get the colour map somehow, not necessary an image.
This is an example of the stored string: 5_____________________________________________________13__2_______________1________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________5
The underscore repreents blue, and the numbers the colour of the data.
Which one of the two solutions could be better for this application?
Heatmap or Pypng library?
