I tried for a long time and couldn't get any better,On different mobile phones:
1. I would like to add pictures and words to the sourceBitmap.
2. want to be able to adjust bitmap and word positions.
Without using library simply we can watermark image using canvas and paint concept
Point point=new Point();
point.set(180, 1000);
Bitmap b=waterMark(BitmapFactory.decodeResource(getResources(), R.drawable.image),"your Text",point,Color.WHITE,90,30,true);
imageView.setImageBitmap(b);
the method code
public Bitmap waterMark(Bitmap src, String watermark, Point location, int color, int alpha, int size, boolean underline) {
//get source image width and height
int w = src.getWidth();
int h = src.getHeight();
Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());
//create canvas object
Canvas canvas = new Canvas(result);
//draw bitmap on canvas
canvas.drawBitmap(src, 0, 0, null);
//create paint object
Paint paint = new Paint();
//apply color
paint.setColor(color);
//set transparency
paint.setAlpha(alpha);
//set text size
paint.setTextSize(size);
paint.setAntiAlias(true);
//set should be underlined or not
paint.setUnderlineText(underline);
//draw text on given location
canvas.drawText(watermark, location.x, location.y, paint);
return result;
}
This method will automatically adjust the size of the watermark text according to the size of bitmap. Additionally it will also add the watermark diagonally if the image is portrait and horizontal if image is landscape
public static Bitmap waterMark(Bitmap src, String watermark, int color, int alpha, int size) {
//get source image width and height
int w = src.getWidth();
int h = src.getHeight();
Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());
//create canvas object
Canvas canvas = new Canvas(result);
//draw bitmap on canvas
canvas.drawBitmap(src, 0, 0, null);
//create paint object
Paint paint = new Paint();
//apply color
paint.setColor(color);
//set transparency
paint.setAlpha(alpha);
//set text size
paint.setTextSize(size);
paint.setAntiAlias(true);
Paint stkPaint = new Paint();
stkPaint.setStyle(Paint.Style.STROKE);
stkPaint.setStrokeWidth(1);
stkPaint.setTextSize(size);
stkPaint.setAlpha(alpha);
stkPaint.setColor(Color.BLACK);
stkPaint.setAntiAlias(true);
//set should be underlined or not
//draw text on given location
canvas.save();
float width = paint.measureText(watermark);
Logger.e("width of bitmap", "" + w);
Logger.e("width of text", "" + width);
if (width > w) {
int i = 2;
while (width > w) {
paint.setTextSize(size - i);
stkPaint.setTextSize(size - i);
width = paint.measureText(watermark);
Logger.e("width of text", "" + width);
i++;
}
} else {
int i = 2;
while (width < w) {
paint.setTextSize(size + i);
stkPaint.setTextSize(size + i);
width = paint.measureText(watermark);
Logger.e("width of text", "" + width);
i++;
}
}
if (w < h) {
canvas.rotate(-60, src.getWidth() / 2, src.getHeight() / 2);
}
float final_x = (src.getWidth() - width) / 2;
Point p = new Point();
p.set((int) final_x, src.getHeight() / 2);
canvas.drawText(watermark, p.x, p.y, paint);
canvas.drawText(watermark, p.x, p.y, stkPaint);
canvas.restore();
return result;
}

I need to change an image, from circle to normal square.
I'm a beginner a few weeks in programming,
I'm 2 days stopped in this code, does anyone know how to change?
I already tried everything, but I could not solve
I do not understand anything about canvas, I've already studied to solve this problem, but I'm still not able to
public static Bitmap getCircleBitmap(Bitmap bitmap) {
final int scaledWidth = 100;
final int scaledHeight = 100;
bitmap = Bitmap.createScaledBitmap(bitmap, scaledWidth, scaledHeight, true);
Bitmap output;
Rect srcRect, dstRect;
float r;
final int width = bitmap.getWidth();
final int height = bitmap.getHeight();
if (width > height) {
output = Bitmap.createBitmap(height, height, Bitmap.Config.ARGB_8888);
int left = (width - height) / 2;
int right = left + height;
srcRect = new Rect(left, 0, right, height);
dstRect = new Rect(0, 0, height, height);
r = height / 2;
} else {
output = Bitmap.createBitmap(width, width, Bitmap.Config.ARGB_8888);
int top = (height - width) / 2;
int bottom = top + width;
srcRect = new Rect(0, top, width, bottom);
dstRect = new Rect(0, 0, width, width);
r = width / 2;
}
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawCircle(r, r, r, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, srcRect, dstRect, paint);
bitmap.recycle();
return output;
}
public static Bitmap getBitmapFromVectorDrawable(Context context, int drawableId) {
Drawable drawable = AppCompatResources.getDrawable(context, drawableId);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
drawable = (DrawableCompat.wrap(drawable)).mutate();
}
Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(),
drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
return bitmap;
}
}
If you look at your code, towards the end of method getCircleBitmap() you have the below line of code:
canvas.drawCircle(r, r, r, paint);
That's the one drawing the circle image for you using DrawCircle.
What you can do is, replace it with DrawRect. That should do that trick for you.
However, if you need to just draw a square image from a vector then you can use a standard ImageView straightaway and use the vector as image resource.
What I Want: I want to add text at bottom of a image which I have chose from either gallery or camera.
Original Image
I added blue color strip to image at bottom
In that strip, I want to add some text exactly in middle.
What's the Problem:
I'm unable to position text exactly in middle of blue color strip.
For different images, text size changes. Some time it is very small, some time it is very big.
What I Tried: My code is like below.
MainActivity.java
public class MainActivity extends AppCompatActivity {

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 101);
}

super.onActivityResult(requestCode, resultCode, data);
if (data != null && resultCode == Activity.RESULT_OK) {

try {
bitmap = MediaStore.Images.Media
.getBitmap(getApplicationContext().getContentResolver(), data.getData());
} catch (IOException e) {

}
addStampToImage(bitmap);
} else if (requestCode == 101) {

fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {

}
addStampToImage(bitmap);
}
}
}

int y = (newBitmap.getHeight() + bounds.height())/5;
canvas.drawText(text, x * scale, y * scale, pText);
mImageView.setImageBitmap(newBitmap);
}
}
Any help will be appreciated!
Updated: 1st Aug 2018
Changes in addStampToImage method.
int extraHeight = (int) (originalBitmap.getHeight() * 0.15);
Rect textHeightWidth = new Rect();
pText.getTextBounds(fromWhichMode, 0, fromWhichMode.length(), textHeightWidth);
canvas.drawText(textToStamp, (canvas.getWidth() / 2) - (textHeightWidth.width() / 2),
originalBitmap.getHeight() + (extraHeight / 2) + (textHeightWidth.height() / 2),
pText);
Above changes giving me text in middle of blue strip. But core ISSUE remains same. i.e Text size changes with respect to different image sizes.
Check the below code:-
private void addStampToImage(Bitmap originalBitmap) {
int extraHeight = (int) (originalBitmap.getHeight() * 0.15);
Bitmap newBitmap = Bitmap.createBitmap(originalBitmap.getWidth(),
originalBitmap.getHeight() + extraHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(newBitmap);
canvas.drawColor(Color.BLUE);
canvas.drawBitmap(originalBitmap, 0, 0, null);
Resources resources = getResources();
float scale = resources.getDisplayMetrics().density;
String text = "Maulik";
Paint pText = new Paint();
pText.setColor(Color.WHITE);
setTextSizeForWidth(pText,(int) (originalBitmap.getHeight() * 0.10),text);
Rect bounds = new Rect();
pText.getTextBounds(text, 0, text.length(), bounds);
int x= ((newBitmap.getWidth()-(int)pText.measureText(text))/2);
int h=(extraHeight+bounds.height())/2;
int y=(originalBitmap.getHeight()+h);
canvas.drawText(text, x, y, pText);
imageView.setImageBitmap(newBitmap);
}
private void setTextSizeForWidth(Paint paint, float desiredHeight,
String text) {
// Pick a reasonably large value for the test. Larger values produce
// more accurate results, but may cause problems with hardware
// acceleration. But there are workarounds for that, too; refer to
// http://stackoverflow.com/questions/6253528/font-size-too-large-to-fit-in-cache
final float testTextSize = 48f;
// Get the bounds of the text, using our testTextSize.
paint.setTextSize(testTextSize);
Rect bounds = new Rect();
paint.getTextBounds(text, 0, text.length(), bounds);
// Calculate the desired size as a proportion of our testTextSize.
float desiredTextSize = testTextSize * desiredHeight / bounds.height();
// Set the paint for that size.
paint.setTextSize(desiredTextSize);
}
Edit:-
Instead of above addStampToImage method you can also use your updated addStampToImage method like below:-
private void addStampToImage(Bitmap originalBitmap) {
int extraHeight = (int) (originalBitmap.getHeight() * 0.15);
Bitmap newBitmap = Bitmap.createBitmap(originalBitmap.getWidth(),
originalBitmap.getHeight() + extraHeight, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(newBitmap);
canvas.drawColor(Color.BLUE);
canvas.drawBitmap(originalBitmap, 0, 0, null);
Resources resources = getResources();
float scale = resources.getDisplayMetrics().density;
String text = "Maulik";
Paint pText = new Paint();
pText.setColor(Color.WHITE);
setTextSizeForWidth(pText,(int) (originalBitmap.getHeight() * 0.10),text);
Rect bounds = new Rect();
pText.getTextBounds(text, 0, text.length(), bounds);
Rect textHeightWidth = new Rect();
pText.getTextBounds(text, 0, text.length(), textHeightWidth);
canvas.drawText(text, (canvas.getWidth() / 2) - (textHeightWidth.width() / 2),
originalBitmap.getHeight() + (extraHeight / 2) + (textHeightWidth.height() / 2),
pText);
imageView.setImageBitmap(newBitmap);
}

I want to add watermark to my app. The screen is divided into 4 rectangle,size of each are ScreenWidth * 1/4ScreenHeight.And each rectangle contains two watermarks.The code is posted below:
final ViewGroup rootView = (ViewGroup) getActivity().findViewById(android.R.id.content);
ScreenInitControl screenInitControl = new ScreenInitControl(getActivity());
int screenWidth = screenInitControl.getScreenWidth();
int screenHeight = screenInitControl.getScreenHeight();
int bitmapWidth = screenWidth;
int bitmapHeight = screenHeight / 4;
Bitmap bitmap = Bitmap.createBitmap(bitmapWidth, bitmapHeight, Bitmap.Config.ARGB_8888);
bitmap.setHasAlpha(true);
Canvas canvas = new Canvas(bitmap);
canvas.drawColor(Color.TRANSPARENT, PorterDuff.Mode.CLEAR);
// init paint
Paint paint = new Paint();
paint.setColor(Color.GRAY);
paint.setAlpha(100);
paint.setAntiAlias(true);
paint.setTextAlign(Paint.Align.LEFT);
paint.setTextSize(50);
// the water mark text
String watermarkText = Config.getIns().getName();
// draw the first watermark in a row
int x = 30;
int y = bitmapHeight / 2;
Path path = new Path();
path.moveTo(x, y);
path.lineTo(bitmapWidth / 2, 30);
canvas.drawTextOnPath(watermarkText, path, 0, 30, paint);
// draw the second watermark in a row
Path path1 = new Path();
x = bitmapWidth / 2 + 30;

canvas.drawTextOnPath(watermarkText, path1, 0, 30, paint);
BitmapDrawable bitmapDrawable = new BitmapDrawable(bitmap);
bitmapDrawable.setTileModeXY(Shader.TileMode.REPEAT, Shader.TileMode.REPEAT);

The code work fine in Samsung galaxy A5. But when I install the app on OPPO R11S, the wartermark comes to be 1/3 size of that in Samsung.Do I ignore something?
Finally,I find it that BitmapDrawable bitmapDrawable = new BitmapDrawable(bitmap) is deprecated. I use BitmapDrawable bitmapDrawable = new BitmapDrawable(getResources(), bitmap) instead and the problem is solved.
I want to add a string on bitmap image.I have a metod drawTextToBitmap,this method working success place string on bitmap image.But my bitmap image is very small like pinmark image.This function set the string based on the bitmap height and width.I want to place the string exceed than the bitmap image.So Please help me to solve the problem.
Following method i am using to get bitmap :
public Bitmap drawTextToBitmap(Context gContext, int gResId, String gText) {
Resources resources = gContext.getResources();
float scale = resources.getDisplayMetrics().density;
Bitmap bitmap = BitmapFactory.decodeResource(resources, gResId);
android.graphics.Bitmap.Config bitmapConfig = bitmap.getConfig();
// set default bitmap config if none
if (bitmapConfig == null) {
bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
}
// resource bitmaps are imutable,
// so we need to convert it to mutable one
bitmap = bitmap.copy(bitmapConfig, true);
Canvas canvas = new Canvas(bitmap);
// new antialised Paint
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
// text color - #3D3D3D
paint.setColor(Color.BLACK);
// text size in pixels
paint.setTextSize((int) (70 * scale));
// text shadow
paint.setShadowLayer(1f, 0f, 1f, Color.BLACK);
// draw text to the Canvas center
Rect bounds = new Rect();
paint.getTextBounds(gText, 0, gText.length(), bounds);
int m = (bitmap.getWidth() - bounds.width()) / 2;
int l = (bitmap.getHeight() + bounds.height()) / 2;
canvas.drawText(gText, 1000, l, paint);
return bitmap;
}
Try this:
public static Bitmap drawStringonBitmap(Bitmap src, String string, Point location, int color, int alpha, int size, boolean underline,int width ,int height) {
Bitmap result = Bitmap.createBitmap(width, height, src.getConfig());
Canvas canvas = new Canvas(result);
canvas.drawBitmap(src, 0, 0, null);
Paint paint = new Paint();
paint.setColor(color);
paint.setAlpha(alpha);
paint.setTextSize(size);
paint.setAntiAlias(true);
paint.setUnderlineText(underline);
canvas.drawText(string, location.x, location.y, paint);
return result;
}
I have some code where I'm drawing my text on bitmap (canvas)
canvas.drawTextOnPath(Text, textPath[count], gipa, -10, text);
Please tell me, it's possible to draw this text in path(textPath) with background color?
it's full function for drawing only text
public void drawText(float x,float y ,String Text,Canvas canvas,Paint paint1 ,int count )
{
float xren =text.measureText(Text.trim());
canvas.drawTextOnPath(Text, textPath[count], gipa, -10, text);
}
Using this function I'm drawing text on my canvas. so how to modify this function for drawing this text with background?
Most likely two steps are needed here. you would draw a line along path first with color for background and then draw the text as indicated. Set the thickness of the line with a paint object. Also, changing the style of the paint can help with the effect. try FILL, STROKE or FILL_AND_STROKE for different effects.
mpaint.setStyle(Paint.Style.STROKE);
mpaint.setStrokeWidth(strokeWidth);
Added sample to draw a path(rectangle) with red color:
Paint mPaint = new Paint();
mPaint.setColor(Color.RED);
Path mPath = new Path();
RectF mRectF = new RectF(20, 20, 240, 240);
mPath.addRect(mRectF, Path.Direction.CCW);
mPaint.setStrokeWidth(20);
mPaint.setStyle(Paint.Style.STROKE);
canvas.drawPath(mPath, mPaint);
Then draw text along same path (blue color):
mPaint.setColor(Color.BLUE);
mPaint.setStrokeWidth(0);
mPaint.setStyle(Paint.Style.FILL);
mPaint.setTextSize(20);
canvas.drawTextOnPath("Draw the text, with origin at (x,y), using the specified paint, along the specified path.", mPath, 0, 5, mPaint);
If you want to make like this then implement below code snippet:
/**
* PUT THIS METHOD FOR IMPLEMENT WATER-MARK IN COMMON FILE
*/
public static Bitmap waterMark(Bitmap src, String watermark) {
//get source image width and height
int w = src.getWidth();
int h = src.getHeight();
Bitmap result = Bitmap.createBitmap(w, h, src.getConfig());
Canvas canvas = new Canvas(result);
canvas.drawBitmap(src, 0, 0, null);
Paint paint = new Paint();
Paint.FontMetrics fm = new Paint.FontMetrics();
paint.setColor(Color.WHITE);
paint.getFontMetrics(fm);
int margin = 5;
canvas.drawRect(50 - margin, 50 + fm.top - margin,
50 + paint.measureText(watermark) + margin, 50 + fm.bottom
+ margin, paint);
paint.setColor(Color.RED);
canvas.drawText(watermark, 50, 50, paint);
return result;
}
// To Get Bitmap from URI:
private Bitmap getBitmapFromUri(String photoPath) {
Bitmap image = null;
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(photoPath, options);
return bitmap;
}
// Save Image :
private String SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/shareImage");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 20, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
return file.getAbsolutePath();
}
// Call like this :
Bitmap bitmap = getBitmapFromUri(attachment.get(i).getPath()); // Enter here your Image path
Bitmap bitmapp = waterMark(bitmap, "ENTER YOUR TEXT FOR WATERMARK LABEL");
String path = SaveImage(bitmapp);
Uri uri = Uri.fromFile(new File(path));
Here at last from uri you can get a new implemented watermark image.
Hope this helps you.
I believe this solution is better and more flexible than drawPath.
Use this to calculate the size of the text background:
private #NonNull Rect getTextBackgroundSize(float x, float y, #NonNull String text, #NonNull TextPaint paint) {
Paint.FontMetrics fontMetrics = paint.getFontMetrics();
float halfTextLength = paint.measureText(text) / 2 + 5;
return new Rect((int) (x - halfTextLength), (int) (y + fontMetrics.top), (int) (x + halfTextLength), (int) (y + fontMetrics.bottom));
}
Then draw the background as a Rect:
Rect background = getTextBackgroundSize(x, y, text, textPaint);
canvas.drawRect(background, bkgPaint);
canvas.drawText(text, x, t, textPaint);
this method i created , it will give you better idea how easily you can do this
public static Drawable getTextToDrawable(final String sText, final float textSize, final int textColor, final int bgColor, final int imageSize) {
Shape shape = new Shape() {
#Override
public void draw(Canvas canvas, Paint paint) {
paint.setTextSize(spToPixel(textSize));
int ivImageSize = SUtils.dpToPx(imageSize);
paint.setTextAlign(Paint.Align.LEFT);
float baseline = -paint.ascent(); // ascent() is negative
int width = (int) (paint.measureText(sText)); // round
int height = (int) (baseline + paint.descent());
Bitmap image = Bitmap.createBitmap(ivImageSize, (int) (ivImageSize), Bitmap.Config.ARGB_8888);
canvas.drawBitmap(image, ivImageSize, ivImageSize, paint);
paint.setColor(bgColor);
if (sText != null) {
if (sText.length() < 3) {
canvas.drawCircle(ivImageSize / 2, ivImageSize / 2, ivImageSize / 2, paint);
paint.setColor(textColor);
canvas.drawText(sText, (ivImageSize - width) / 2, (height+baseline)/2, paint);
} else {
canvas.drawRect(0, 0, ivImageSize, height, paint);
paint.setColor(textColor);
canvas.drawText(sText, (ivImageSize - width) / 2, baseline, paint);
}
}
}
};
return new ShapeDrawable(shape);
}
