Set the Options.inJustDecodeBounds to true and call the BitmapFactory's method to get/decode your bitmap. The bitmap returned will be null, but the Options.outWidth and Options.outHeight will be set to the image's width and height in pixels.
Then call the BitmapFactory's method to get/decode your bitmap again, with Options.inJustDecodeBounds set to false and its inSampleSize set to your liking. BTW: This is all in the documentation: http://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inJustDecodeBounds On Jun 4, 4:37 am, quill <[email protected]> wrote: > Hi all, > I want to know an image's width before decode it, so that I can set > Options.inSampleSize if the image is too large.
