Flex-从多个图像的位图数据（拖放） [英] Flex- Bitmapdata from multiple images (drag & dropped)

问题描述

对不起，如果问题标题有点混乱（不是非常有创意:)这是问题。

我从BitmapData中加载图像显示在图像控制。这个Image控件有dragEnabled，用户可以在它的顶部拖放小图像（从TileList中的一堆图像）。

从Bitmapdata加载的图像每次分辨率不同时都会有所不同，Image控件会缩小图像以适合其固定的高度。但在编辑后保存图像时，我将其原始宽度/高度保存。为此，我将原始Bitmapdata存储在一个临时对象中，并在保存之前对其进行编辑。

我的问题在于，我不知道如何创建一个图像，将大图像和小图像合并到一起。可能是我可以使用显示对象快照，但然后我想保存图像的原始与/高度，最好转换为Bitmapdata后。任何帮助如何去做这个？除了从前面的帖子合并方法（），你可以使用BitmapData :: draw（）方法。

该方法允许您合并缩放的位图，而merge（）只适用于原始大小的位图。

Sorry, if the question title is little confusing (not very creative at it :) Here's the problem .

I have an image loaded from BitmapData displayed in an Image control. This Image control has dragEnabled and user can drag and drop small images (from a bunch of images in a TileList) on top of it.

The image loaded from the Bitmapdata can be different every time with different resolution and the Image control scales it down to fit its fixed with/height. But while saving the image after editing I am saving it with its original width/height. For this purpose I am storing the original Bitmapdata in a temp object and applying any edits there before saving.

My problem here is that I have no clue on how to create an image combining the Large image and the small images dropped into it. May be I can use display object snapshot but then I want to save the image with its original with/height and preferably after converting it to Bitmapdata. Any help on how to go about this?

解决方案

In addition to merge method() from the previous post you can use BitmapData::draw() method. http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/BitmapData.html#draw%28%29

The method allows you to combine scaled bitmaps while merge() works only with original sizes of bitmaps.
