I need a small help on rotating one image around its center of axis among multiple images which are drawn to canvas in android.
I am loading images to canvas like below.
canvas.drawBitmap(mMachineBackground, 0, 0, null);
canvas.drawBitmap(mMachineRotator, 0, 0, null);
I want to rotate only the second bitmap around its center of axis instead of rotating the entire canvas(which includes first bitmap also).
I have some images (.png format) that I use as drawables on the surface of canvas in my android app. The problem I have is mspaint only allows a rectangular image file, so whatever I draw on the screen always shows up in a box. Is there a (free) program or way I can edit the png files so that when they are drawn on the surface of my canvas, they are drawn to shape?

View 30 Replies View RelatedI'm just starting with Android development and I'm coming from JavaScript/HTML world so I'm currently investigating the possibilities of the Android SDK.
The HTML 5 canvas supports composite operations (See here).
Is this possible in an Android Canvas? I scanned the API of the Canvas class but couldn't find anything useful. I need at least the composite operation "source-in" or (if this isn't possible) "source-atop".
Can anybody tell me or send me some links if there is any..which tells how Google map draw on canvas in android. what is the logic behind that.
View 1 Replies View RelatedI'm currently writing an Android game using surfaceView. I've optimized the game as much as possible and it runs quite smoothly. However, I have collision detection incorporated which is a bit messy. I would like to do collision detection by reading pixels directly from the canvas. Is this possible to do? The closest to this that I have found was to attach a new bitmap to the canvas using setBitmap. Then when I drew to the canvas, the bitmap would be updated. Would this be the way to go?

View 1 Replies View RelatedI'm basically using the same method of loading bitmaps in OpenGL that the SpriteMethodTest example uses and have been unable to get rid of an annoying outline that appears around all of my images.
For example, If I were to load an image of a white circle on a white background, I would expect to see nothing. Instead, I would see my circle because its edge would be gray. In SpriteMethodTest, I replaced the background image with white and was able to see that the edges of the android images flying around also don't seem to be rendered correctly.
Does anyone know how to load images in OpenGL without having a thin outline appear around the images?

View 2 Replies View RelatedI am trying to rotate a canvas with canvas.rotate and move an object on it at the same time. The problem is that with the rotation, the coordinate system of the canvas rotates as well, so I get cases when my object is supposed to be moving along the y axis, but the y axis is rotated on place of the x axis. It is a mess. Is there a way to go around this?
View 1 Replies View RelatedI'm working to convert some background images to nine patch so they scale better on different phones.
The problem is that if I have the following resource structure: drawable-hdpi/background.png drawable-hdpi/button.png drawable-mdpi/background.png drawable-mdpi/button.png drawable-ldpi/background.png drawable-ldpi/button.png and then I drop a new drawable-hdpi/background.9.png file into the mix, it breaks button.png during the pre-compile. The error is "No resource found that matches the given name (at 'background' with value '@drawable/button').Simply removing that one nine patch file fixes the build. Should I be able to have some nine patch images and some normal ones, or to have nine patch only in hdpi but not mdpi or ldpi? This is Eclipse 3.5.1 with the latest ADT.
I currently have a game written using the Android canvas. It is completely 2D, and I draw bitmaps as sprites on the canvas, and it technically works, but I have a few features that I need to add that will require drawing many more bitmaps on the screen, and there will be a lot more movement.
The app needs more power.
What is the best way to go from this method of drawing Bitmaps on a canvas to using OpenGL so I can draw them faster?
1.myJpegFile = new File("images/jpegImage.jpg");
2.output = new BufferedOutputStream(new FileOutputStream(myJpegFile));
3.encoder = JPEGCodec.createJPEGEncoder(output);
4.encoder.encode(myJpegImage); Please could you give me the equivalent code for line no. 3 and 4 in Android?
I m making an application which requires me to list all the images available on the SD-Card of the phone.
i tried querying the ContentResolver way i.e.
Cursor image = getContentResolver().query(Images.Media.EXTERNAL_CONTENT_URI, new String[]{Images.Media._ID,Images.Media.DATA,Images.Media.DISPLAY_NAME}, null, null, null);
but without any result. Is there any way i can get the list or if thats not possible then is there any possible intent (e.g. PICK) by which i can allow the user to select a file and then access the path of the file the user selected?

View 2 Replies View RelatedI have 24 .png images and a ImageView. On user touch I change the ImageView to be one of the 24 images. I'm currently doing setImageResource(R.drawable.hour_1);, but there is a slight delay after I touch the screen and the ImageView actually changes. I figure the delay is the resource being loaded, but I can't find a better way to do this.
View 1 Replies View RelatedI am developing a Java Android application that displays web content from the assets folder in a web view. I had no problem getting this content to display in the application but I am confused as to why my images are not displaying properly. I'm working with a Motorola Droid that is supposed to be 480x854 resolution. When I create banner images using these dimensions and attempt to display them in the web view they're enormous and they flow off of the screen. It doesn't appear that the web view is actually 480x854. Can somebody let me know what I am missing here? I do not know what size to set the images to so they are just right.

I am trying to write an application, that would allow me to render multiple images onto an ImageView in Android. I can find the method to populate it with a sigle bitmap.

View 2 Replies View RelatedI need to upload an image to a remote PHP server which expects the following parameters in HTTPPOST:
*$_POST['title']*
*$_POST['caption']*
*$_FILES['fileatt']*
Most of the Internet searches suggested either :
Download the following classes and trying MultiPartEntity to send the request:
apache-mime4j-0.5.jar
httpclient-4.0-beta2.jar
httpcore-4.0-beta3.jar
httpmime-4.0-beta2.jar
OR
Use URLconnection and handle multipart data myself.
Btw, I am keen on using HttpClient class rather than java.net(or is it android.net) classes. Eventually, I downloaded the Multipart classes from the Android source code and used them in my project instead.
Though this can be done by any of the above mentioned methods, I'd like to make sure if these are the only ways to achieve the said objective. I skimmed through the documentation and found a FileEntity class but I could not get it to work.
What is the correct way to get this done in an Android application?
