Convert String text to Bitmap

android, bitmap, image

Solution

You can create a Bitmap of the appropriate size, create a Canvas for the Bitmap, and then draw your text into it. You can use a Paint object to measure the text so you'll know the size needed for the bitmap. You can do something like this (untested):

public Bitmap textAsBitmap(String text, float textSize, int textColor) {
    Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
    paint.setTextSize(textSize);
    paint.setColor(textColor);
    paint.setTextAlign(Paint.Align.LEFT);
    float baseline = -paint.ascent(); // ascent() is negative
    int width = (int) (paint.measureText(text) + 0.5f); // round
    int height = (int) (baseline + paint.descent() + 0.5f);
    Bitmap image = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(image);
    canvas.drawText(text, 0, baseline, paint);
    return image;
}

Problem

Is it possible to convert string text that is inside an `EditText` box into a Bitmap? In other words, is there any way to convert string text into a Bitmap that means the text will display as an image? Below is my Code: ``` class TextToImage extends Activity { protected void onCreate(Bundle savedInstanceState) { //create String object to be converted to image String sampleText = "SAMPLE TEXT"; String fileName = "Image"; //create a File Object File newFile = new File("./" + fileName + ".jpeg"); //create the font you wish to use Font font = new Font("Tahoma", Font.PLAIN, 11); //create the FontRenderContext object which helps us to measure the text FontRenderContext frc = new FontRenderContext(null, true, true); } } ```
