View 2 Replies View RelatedAndroid :: Convert A Bitmap To GrayScale In Droid?
Jul 30, 2010I am new to this site, and I come with a question about Android.
Is there any way to convert a Bitmap to grayscale? I know how to draw a grayscale bitmap (using canvas operations: http://www.mail-archive.com/android-developers@googlegroups.com/msg38890.html) but I really need The actual bitmap in gray colors (or at least something that could be converted to a bitmap later on).
Do I have to implement it by hand (pixel by pixel operations)?
I've searched a lot, and still could not find. Anyone knows a easy/efficient way to do it?
Android :: Convert A View To Bitmap Without Displaying It In Droid?
May 10, 2010I will try to explain what exactly I need to do.
I have 3 separate screens say A,B,C. There is another screen called say HomeScreen where all the 3 screens bitmap should be displayed in Gallery view and the user can select in which view does he wants to go.
I have been able to get the Bitmaps of all the 3 screens and display it in Gallery view by placing all the code in HomeScreen Activity only. Now, this has complicated the code a lot and I will like to simplify it.
So, can I call another Activity from HomeScreen and do not display it and just get the Bitmap of that screen. For example, say I just call HomeScreen and it calls Activity A,B,C and none of the Activities from A,B,C are displayed. It just gives the Bitmap of that screen by getDrawingCache(). And then we can display those bitmaps in Gallery view in HomeScreen.
I hope I have explained the problem very clearly.
Please let me know if this is actually possible.
Android :: Masking A Drawable/Bitmap?
Apr 12, 2010I'm currently looking for a way to use a black and white bitmap to mask the alpha channel of another bitmap or Drawable on Android. I'm curious as to what the best way to do this is. I certainly have a couple of ideas for how to do this, but they are not optimal.
I need to be able to apply a new mask to the image every so often (the black and white bitmap will change every few seconds).

View 1 Replies View RelatedAndroid :: Display Animated Gif / Extract Frames From It And Convert Them Into Drawable?
Sep 7, 2010I want to display animated gifs in my aplication.
As I found out the hard way Android doesn't support animated gifs natively.
However it can display animations using AnimationDrawable:
http://developer.android.com/guide/topics/graphics/2d-graphics.html#frame-animation
The example uses animation saved as frames in application resources but what I need is to display animated gif directly.
My plan is to break animated gif to frames and add each frame as drawable to AnimationDrawable.
Does anyone know how to extract frames from animated gif and convert each of them into Drawable?
Android :: How To Convert Picture Object To Bitmap?
Jun 4, 2009I am trying to figure out how to do conversion of Picture object generated by web View to Bitmap for later JPEG encoding and saving to local f/s.

Just wondering is there any method to do the conversion?

View 4 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.

View 1 Replies View RelatedAndroid : Want To Create Empty Drawable In Droid?
Feb 10, 2010Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?
View 4 Replies View RelatedAndroid :: Many Image Files In Res / Drawable - Access In Droid?
Feb 11, 2010I have to make a dedicated image viewer app for Android 2.x.
There are too many jpeg image files: about 2000~ jpegs, over 100MB.
I want access the image files with their file names,
but I couldn't find such an example.
By the way, is it okay to put many image files in /res/drawable folder?
I heard that the android application cannot be installed on sdcard and
the program repository is very small so 100MB app cannot be installed generally.
I found some examples which download the large data files on sdcard online,
but I cannot run a web server to host the data files,
and I must upload the fully packaged program on Android Market. (Should I build one apk file?)
What are the best practices for managing too many resource images (or something) in Android?

Jul 6, 2010I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files.
Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc.
