问题描述

我发现画廊，双指缩放的样本项目，并取得了一些bug修复。您可以下载我的code在这里

I found a sample project of gallery with pinch zoom and made some bug fix. You can download my code at here

它支持全屏只。它总是居中图像屏幕的高度。但我想把一个头，以便在屏幕的顶部，使调整到图像的位置。图像的位置应该是：

It supports full screen only. It always center the image to screen height. But I want to put a header view to the top of the screen and make the adjustment to the location of the image. The image location should be:

header height + (screen height - header height) / 2

我不使用矩阵那么好。任何人有如何使自定义库的任何大小的工作（不只是全屏幕）的想法？

I am not so good at using Matrix. Anyone has idea of how to make the customized gallery to work in any size (not just full screen)?
