* Use a host java program to generate the background textTianjie Xu2018-10-131-0/+23
This program uses java.awt.Graphics2D to generate the background text files used under recovery mode. And thus we don't need to do the manual work by running emulators with different dpi. The program takes the following parameters: 1. imageWidth: The number of pixels per line; and the text strings will be wrapped accordingly. 2. textName: The description of the text string, e.g. "recovery_erasing", "recovery_installing_security" 3. fontDirectory: The directory that contains all the support .ttf | .ttc files, e.g. $OUT/system/fonts/ 4. resourceDirectory: The resource directory that contains all the translated strings in xml format, e.g. bootable/recovery/tools/recovery_l10n/res/ 5. outputFilename: Path to the generated image. Bug: 74397117 Test: checks the generated png files Change-Id: Ia5506a0a4f5da1ebfd7090345eb246f44b265075
