# Bitmap Model The value of the Bitmap model is the sum of bytes used for native pixel data of instances of `android.graphics.Bitmap`. It is calculated by summing for each instance `x` of `android.graphics.Bitmap`: x.getAllocationByteCount() The actionable breakdown of the Bitmap model is a breakdown by `android.graphics.Bitmap` instance, including width, height, and ideally a thumbnail image of each bitmap. For example, an 800 x 600 bitmap instance using the `ARGB_8888` pixel format with native pixel data will be shown as an 800 x 600 bitmap instance taking up 1875 kB.
