use of com.codename1.components.FileEncodedImage in project CodenameOne by codenameone.

the class FileEncodedImage method create.

/**
 * Creates an encoded image that maps to a local file thus allowing to
 * seamlessly fetch files as needed. This only works reasonably well for very small
 * files. This version of the method creates the file from an input stream
 *
 * @param fileName the name of the file
 * @param i input stream from which to create the file
 * @param width the width of the file or -1 if unknown (notice that this will improve performance)
 * @param height the height of the file or -1 if unknown (notice that this will improve performance)
 * @return image that will load the file seamlessly
