First, ignore this sentence below from my previous answer entirely: "Save the byte[] data from the camera into file directly (this is your JPG file)." (It was a left-over chunk of my initial answer) The 'byte[] data' still takes up memory, because the caller (the Android SDK code that calls the

Dealing with ARGB_ full-sized images may just not be possible for certain devices (e.g. 5MPixel images taking 20Mbyte of memory, not leaving much room for anything else). Unless you can decode the byte[] data from the Camera yourself... this would mean writing your own JPG decoder that woul

Re: [android-developers] need help working with very large (photo) bitmaps

The size of the JPG/PNG file has almost nothing to do with the size of the corresponding image in memory. An RGB_565 takes 2 bytes per pixel (5+6+5=16bits=2bytes). An ARGB_ takes 4 bytes per pixel. This means a 5MPixel image will take 5M*2 = 10MByte in RAM when using RGB_565 or 5M*4=20MByte

Re: [android-developers] need help working with very large (photo) bitmaps

I'm not saying you dreamed those up, sorry, no offence meant. But since we seem to be discussing memory usage, not disk usage, the compressed size is irrelevant. And 5 megapixels at RGB_ is 32 bits per pixel or 20 megabytes in RAM, if stored as an uncompressed pixel array. -- K On 04/1

The question about blending methods resolved itself when I switched to making the bitmaps for filters in the app. But one question still remains, and I need help with this one. When trying to blend the full-size camera image with an equal-size bitmap for the filter, unless I reduce the image size
