Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
As for this, you could try UVTools. I just used it to open an existing ctb file (any will do), remove all layers but one, and then replace that layer with a monochrome image file of my choosing.
