BatchTexter

This project shows how to generate image resources from text.

Requirements

• ImageMagick (https://www.imagemagick.org/script/index.php)

  • Ensure that your Terminal / Console will know ImageMagick's commands.

• You may want to install Droid-Sans, which is the default font in Android. The .ttf files can be found in the fonts directory of this repo.

How it works

1. Generate text which will be batch-processed. Main.java can be used to get a processable text file. This file shows a text which can be batch-processed.
2. Set up the batch file. This template gives you an idea.
3. Run the batch file.
4. Compress / optimize.

Modifications

File Creation

Change generateContent() in Main.java

Percentage values

private static void generateContent() {
    System.out.println("Creating percentage asset");
    String content = loopPercentage("img_p###:###%", "###", 100);
    showInConsole(content);
    writeToFile("_resource_set.txt", content);
}

Byte values

private static void generateContent() {
    System.out.println("Creating percentage asset");
    String content = loopPercentage("img_b###:###B/s", "###", 1024);
    showInConsole(content);
    writeToFile("_resource_set.txt", content);
}

ImageMagick Parameters

   -background transparent \
   -fill white \
   -font Droid-Sans \
   -size 96x96 \
   -gravity center \
   label:"$text" \
   $id.png

Notes

• The generated .png-files are not compressed. Keep in mind that compressed files can be processed faster and will result in a better performance.
• The processable text file requires a linebreak at the end of the file.
• Since the amount of the characters varies, you will have to cherry-pick the suitable images from the sub-folders you find in batch/ manually. An other solution is telling ImageMagick to size the content automatically. However, the current output in batch/ may be cut off.

Since Android allows only .png-files in the status-bar this project provides a easy solution to show a very short text or a symbols by generating an image.
