* POV Display usermod this usermod adds a new effect called "POV Image". To get it to work: - read the README :) - upload a bmp image to the ESP filesystem using "/edit" url. - select "POV Image" effect. - set the filename (ie: "/myimage.bmp") as segment name. - rotate the segment at approximately 20 RPM. - enjoy the show! * improve file extension checks * improve README, remove PNGdec reference, clean usermod * restrain to esp32 platform + reduce memory footprint with malloc

/*
|
|
* This class describes a bitmap image. Each object refers to a bmp file on
|
|
* filesystem fatfs.
|
|
* To initialize, call init(), passign to it name of a bitmap file
|
|
* at the root of fatfs filesystem:
|
|
*
|
|
* BMPimage myImage;
|
|
* myImage.init("logo.bmp");
|
|
*
|
|
* For performance reasons, before actually usign the image, you need to load
|
|
* it from filesystem to RAM:
|
|
* myImage.load();
|
|
* All load() operations use the same reserved buffer in RAM, so you can only
|
|
* have one file loaded at a time. Before loading a new file, always unload the
|
|
* previous one:
|
|
* myImage.unload();
