And thus we don't need to do the manual work by running 6*e7c364b6SAndroid Build Coastguard Workeremulators with different dpi. 7*e7c364b6SAndroid Build Coastguard Worker 8*e7c364b6SAndroid Build Coastguard Worker# Usage: 9*e7c364b6SAndroid Build Coastguard Worker `java -jar path_to_jar --image_width imageWidth --text_name textName --font_dir fontDirectory 10*e7c364b6SAndroid Build Coastguard Worker --resource_dir resourceDirectory --output_file outputFilename` 11*e7c364b6SAndroid Build Coastguard Worker 12*e7c364b6SAndroid Build Coastguard Worker# Description of the parameters: 13*e7c364b6SAndroid Build Coastguard Worker1. `imageWidth`: The number of pixels per line; and the text strings will be 14*e7c364b6SAndroid Build Coastguard Worker wrapped accordingly. 15*e7c364b6SAndroid Build Coastguard Worker2. `textName`: The description of the text string, e.g. "recovery_erasing", 16*e7c364b6SAndroid Build Coastguard Worker "recovery_installing_security" 17*e7c364b6SAndroid Build Coastguard Worker3. `fontDirectory`: The directory that contains all the support .ttf | .ttc 18*e7c364b6SAndroid Build Coastguard Worker files, e.g. $OUT/system/fonts/ 19*e7c364b6SAndroid Build Coastguard Worker4. `resourceDirectory`: The resource directory that contains all the translated 20*e7c364b6SAndroid Build Coastguard Worker strings in xml format, e.g. bootable/recovery/tools/recovery_l10n/res/ 21*e7c364b6SAndroid Build Coastguard Worker5. `outputFilename`: Path to the generated image. 22*e7c364b6SAndroid Build Coastguard Worker 23*e7c364b6SAndroid Build Coastguard Worker# Locales 24*e7c364b6SAndroid Build Coastguard WorkerSupported locales and background texts are located in 25*e7c364b6SAndroid Build Coastguard Worker[tools/recovery_l10n/res/](../recovery_l10n/res/values). For each background text, the tool renders 26*e7c364b6SAndroid Build Coastguard Workera localized image for every supported locale. 27*e7c364b6SAndroid Build Coastguard Worker 28*e7c364b6SAndroid Build Coastguard WorkerEach individual localized image contains an encoded locale header string, and the rendered 29*e7c364b6SAndroid Build Coastguard Workerbackground text. The locale header string is generated by `Locale.forLanguageTag`. And sample 30*e7c364b6SAndroid Build Coastguard Workerresult include `en-US`, `zh-CN`, etc. These individual images are then concatenated together to 31*e7c364b6SAndroid Build Coastguard Workerform the final resource image that locates in res/images, e.g. `install_text.png` 32
