Jun 2, 2009I can't seem to get the BlurMaskFilter to work the way I want. When I set a BlurMaskFilter as part of my Paint object and then draw a bitmap only the edges of the bitmap are blurred. Is there some secret way of blurring the entire bitmap? I noticed there's not really any sample code in the demo app or anywhere else on the web that I can find and the java docs for this class are sparse to say the least.

View 2 Replies View RelatedAndroid :: How To Obtain The Current Bitmap Of A Canvas
Nov 16, 2010I want to get the current bitmap associated with my canvas so I can perform operations on it. I can't see how to do this though.
I've seen some examples where you create a bitmap and set the canvas to use this bitmap, so obviously you can then access it later, but I'm using the canvas returned from a SurfaceHolder so there's no constructor.
For instance, examples often show this kind of thing:
CODE:...........
So at this point I can see bmp.
In my case, the canvas is obtained by:
CODE:......
So how can I get the bitmap for c?
In short, my aim is to capture the current canvas contents where I have drawn "stuff", and make a copy of it, reversed, to put underneath. Like a reflection. The example of this that I found performed it all via bitmaps, so I assumed I needed to somehow capture the current canvas to a bitmap to then use it.
Android :: Invert A Bitmap When Using Canvas.DrawBitmap?
May 14, 2010I am starting to develop a game. Right now I got a sprite animation going when a player moves across using sprite sheet. In my sprite sheet the character is always facing the same way, left. Now if I want the character to move right, I want it to be facing right. So is there a quick way in android to invert the bitmap after it has been loaded in? Or do I have to create sprite sheet for character facing right?

Mar 25, 2010I want to draw a bitmap on a canvas with bigger size than it is. I can use canvas.drawBitmap(bitmap, null, destRect, null); but that gives a poor quality, as the result is pixelated, if the source image is sightly smaller than the destination rectangle. How can i draw my bitmap using bilinear or bicubic resampling?

Sep 10, 2013At canvas there are many methods (canvas.rotate (35); canvas.drawBitmap (myBitmap, x, y, null); and many other things), but the method of mirror reflexion of image is absent (or I have not found it).

View 6 Replies View RelatedAndroid :: Rotate Bitmap With Canvas.rotate
Sep 24, 2010As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!
View 3 Replies View RelatedAndroid : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I 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?
Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It
Apr 2, 2009I 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.

Jan 14, 2010Currently in an Android application that I'm developing I'm looping through the pixels of an image to blur it. This takes about 30 seconds on a 640x480 image.While browsing apps in the Android Market I came across one that includes a blur feature and their blur is very fast (like 5 seconds) so they must be using a different method of blurring.Anyone know a faster way other than looping through the pixels?

Android :: Pros And Cons - Sense Vs Ninja Blur
Sep 1, 2010I was wondering if anyone could help me make my decision between the HTC Incredible, the Droid 2 and the Droid X. I'm leaning towards the Droid X at this point over the Droid 2, because the physical keyboard seems superfluous. I type much more quickly on my iPod Touch than I do on my phone, which has a physical qwerty on it. I'm hoping Swype and a bigger screen will make it even better. For that reason, the Droid 2 is kind of a long shot, in my opinion.
Alas, it's mostly down to the X and the Incredible. After having read up on the specs of both rather extensively for the past few weeks (I'll have money to kill my AT&T contract and get on with Verizon sometime this month), the only thing I haven't been able to research very well is Sense versus the stripped-down version of Blur on the phones.
