This program is designed to convert scanned 12-lead
|
|
electrocardiograms into PNG format and a web-friendly
|
|
image size. It assumes that the electrocardiogram (ECG)
|
|
is printed with a black line on white paper with a red grid.
|
|
|
|
The problems this program is designed to solve are (1) an
|
|
ECG scanned at relatively high resolution (300 to 600 dots
|
|
per inch) imposes a substantial load on the web browser
|
|
because it contains about 6 million pixels which may require
|
|
18 to 24 MB of RAM to store for display. Also, (2) typical
|
|
scanners convert a clean paper ECG into a multitude of colors,
|
|
include green and blue. The resulting file cannot be compressed
|
|
efficiently because it does not contain as much redundancy, and
|
|
thus takes more time to transmit over low-speed network connections.
