* Adjust the background text image width to reduce its sizeTianjie Xu2018-11-151-26/+81
| | | | | | | | | | | | | | We can adjust the image width with respect to the maximum width of the wrapped text. This will remove some black margins and reduce the final size of the images, especially for those with short strings, e.g. "recovery_error". Also, add an option to centrally align the text; and fix a boundary check in the recovery resource test. Bug: 74397117 Test: Generate and check the image Change-Id: Ib6cf61a9c99c4aeede16751dc0adfa23ce3f5424
* image generator: format the java fileTianjie Xu2018-11-131-469/+482
| | | | | | | | | Format the file with google-java-format --aosp. This makes the presubmit hook happy. Bug: 74397117 Test: mma Change-Id: Ie342ed11449414b63f2d1ae781023e940b136bcb

* Make the text image readable under recoveryTianjie Xu2018-11-011-14/+123
| | | | | | | | | | | | Encode the width, height and locale of the localized image as pixels so that recovery can locate the correct range of the image from a concatenated png file. Also address a few todoes including wrapping the CJK text, making a catch-all type for all languages. Test: view the generated image under locale test Change-Id: Icd3997eb4e992e76ef72526787d64c406f606970
* Switch to use commandline parserTianjie Xu2018-10-293-15/+72
| | | | | | | | | The commandline parser adds some flexibility to the argument parsing. It also makes the help message more descriptive. Bug: 74397117 Test: generate a image, checks the help message Change-Id: Ib238658a9a6fa8806f1b0dde419c8fb970e7cb37
* Use a host java program to generate the background textTianjie Xu2018-10-134-0/+438
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
