Android : Round Corners On Bitmap?
Jan 18, 2009I have taken a drawable (picture) and split it into multiple Bitmaps. Now I would like to round the corners on the Bitmap. Is there any way to do this?

I have taken a drawable (picture) and split it into multiple Bitmaps. Now I would like to round the corners on the Bitmap. Is there any way to do this?
how to do this:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" androidadding="10dp">
<solid android:color="#FFFFFF"/>[code]....
I want to dynamically change that to use the xml drawable
OR
dynamically round the corners.
I am trying to find solution where I can apply round corners to an image. 1) I have tried to set android:background and in drawable.

CODE:.........
I have seen the Canvas method: public void drawBitmap (Bitmap bitmap, Rect src, RectF dst, Paint paint)
However I believe this takes the top, right, bottom and left coordinates to draw the Bitmap and not the corner coordinates. I need to specify the CORNER coordinates to draw the bitmap as I may need to stretch/distort the Bitmap (I am drawing the Bitmap on a 3D spherical model).
I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.
I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?
My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

View 1 Replies View RelatedSo I'm finally settling down on a ROM configuration I like. I'm currently using the following:
DamageControl 3.2.3
DroidX Boot Screen
Rotary Lockscreen
ADW Launcher
It's a great combination, but the one thing I miss right now came from the BakedSnack 9.6 ROM and that's the 6 segmented round battery meter in the status bar. Anyone know how to get that or at least something better than the default battery icon?
Heres a custom round battery icon I made this morning. I didn't really like any of the ones already on here so I made this. Its green 100-60, yellow at 40, orange at 20 and last but not least red at 10. Should install via MM.

When I'm typing really fast and drag my fingers to type "saw" for example with just my left thumb I'll catch the bottom left of the W key while the A is pressed down and it'll lift up and make a popping noise. I'm worried eventually I'll snap the W off the keyboard.
