Note that they can be U first, and V after, or V and after it U, and maybe interlived (that is the common case case with Camera2 API). In same manner you can get the U+V parts to.
The yImage byte buffer is actually the gray pixels of the frame.
#Android imate code
To get it I suggest code like this: Image.Plane planes = image.getPlanes() In many Image Processing cases you need only the Y plane, that means the gray part of the image. Note that the Image object that you get from the camera, it's just a YUV frame, where Y, and U+V components are in different planes. If i have understand you you want to create a scaled bitmap from another.Below is a snippet of code that will allow you to resize a Bitmap.1) How do you loop throw pixelsĢ) How do you convert to Bitmap Now it is showing me null pointer exception. image2 = codeResource(getResources(), rid)
This.layout(0, 0, this.getMeasuredWidth(), this.getMeasuredHeight()) īitmap image = Bitmap.createBitmap(this.getDrawingCache()) MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)) asure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), Without it the view will have a dimension of 0,0 and the bitmap will be null can nay one suggest meĮdited : tDrawingCacheEnabled(true) in my desired output height is get large. it is showing me the same width and height but my desired output is not coming. Int yBm = (int)(y * (bmHeight / getHeight())) īut it is not returning me the same output. Int xBm = (int)(x * (bmWidth / getWidth())) Convert touched x, y on View to on Bitmap Log.w("DEBUG","which is null:image " + image.getWidth() + " OR " +image.getHeight() )
Log.w("DEBUG","which is null:image2 " + image2.getWidth() + " OR " +image2.getHeight() ) īitmap image = Bitmap.createScaledBitmap(image2, i.getWidth(), i.getHeight(), false) Log.w("DEBUG","which is null:image h " + h.getWidth() + " OR " +h.getHeight() ) Log.w("DEBUG","which is null:image i " + i.getWidth() + " OR " +i.getDrawable().getIntrinsicHeight () ) image2 = codeResource(getResources(), rid) I want to create a bitmap image of particular image but i want to resist the width and height of the bitmapimage.
