问题描述
我开发一个应用程序,我需要生成的文本图像和图像存储和SD卡。结果
谁能告诉我一个图书馆(就像textimagegenerator用于Java)我需要兼容的Android库或来源,我可以用这个?
解决方案
的TextView的TextView =新的TextView(activity.getContext());
textView.setText(的Hello World);
textView.setDrawingCacheEnabled(真);
textView.destroyDrawingCache();
textView.buildDrawingCache();
位图的位图= getTransparentBitmapCopy(textView.getDrawingCache());
私人位图getTransparentBitmapCopy(位图源)
{
INT宽度= source.getWidth();
INT高度= source.getHeight();
位图副本= Bitmap.createBitmap(宽度,高度,Bitmap.Config.ARGB_8888);
INT [] =像素新INT [宽*高]。
source.getPixels(像素,0,宽度,0,0,宽度,高度);
copy.setPixels(像素,0,宽度,0,0,宽度,高度);
返回副本;
}
I am developing an application where I need to generate an Image from text and store that Image to the SDCard.
Can anyone tell me a library(just like textimagegenerator for java) I need android compatible library or source which I can use for this?
解决方案
TextView textView = new TextView(activity.getContext());
textView.setText("Hello World");
textView.setDrawingCacheEnabled(true);
textView.destroyDrawingCache();
textView.buildDrawingCache();
Bitmap bitmap = getTransparentBitmapCopy(textView.getDrawingCache());
private Bitmap getTransparentBitmapCopy(Bitmap source)
{
int width = source.getWidth();
int height = source.getHeight();
Bitmap copy = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
int[] pixels = new int[width * height];
source.getPixels(pixels, 0, width, 0, 0, width, height);
copy.setPixels(pixels, 0, width, 0, 0, width, height);
return copy;
}
