Android的code相机意向+ Croping图片说明 [英] Explanation of Android Code Camera Intent + Croping Images

问题描述

在想拍照，裁剪并保存图像中的Andr​​oid应用程序，我用下面的意图在我的Java ...

When wanting to take a photo, crop and save the image in an Android application, I use the following intent in my Java...

            Intent camera=new Intent();
            camera.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
            camera.putExtra("crop", "true");
            camera.putExtra("outputX",600);
            camera.putExtra("outputY", 600);
            camera.putExtra("aspectX", 1);
            camera.putExtra("aspectY", 1);
            camera.putExtra("scale", true);
            camera.putExtra("return-data", false); 

以上意向的伟大工程，但是我的Y和X总是相等的。我期待打破code找出指定，这样我可以定制的 - 最重要的独立 - X和我所拍摄的图像Y值和要剪裁...

The above intent works great, however my Y and X are always equal. I am looking to break down the code to find out what specifies this so that I can make customisable - and most importantly independent - X and Y values for the image which I have taken and wish to crop...

推荐答案

注：由于使用camera.putExtra（裁剪，真）; 不建议... 查看评论上面的内容......纵横部分然而没有解决我的问题！

NOTE : THE USE OF camera.putExtra("crop", "true"); IS NOT ADVISED... See Comments above for details... The aspect parts did however fix my issues !

            Intent camera=new Intent();

            /** This specifies the action for this intent when it is called. */
            camera.setAction(MediaStore.ACTION_IMAGE_CAPTURE);

            /** This says yes we can crop the image. */
            camera.putExtra("crop", "true");


            /** These provide the initial dimensions for X and Y. */
            camera.putExtra("outputX",600);
            camera.putExtra("outputY", 600);

            /** These provide the relative aspects. */
            camera.putExtra("aspectX", 1);
            camera.putExtra("aspectY", 1);


            /** These I am unsure about. */
            camera.putExtra("scale", true);
            camera.putExtra("return-data", false); 

这样的方面设置为0而不是1，

            /** These provide the relative aspects. */
            camera.putExtra("aspectX", 0);
            camera.putExtra("aspectY", 0);

它们成为彼此独立...

They become independent of each other...

问题解决了！

FINAL code

            Intent camera=new Intent();
            camera.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
            camera.putExtra("crop", "true");
            camera.putExtra("outputX",600);
            camera.putExtra("outputY", 600);
            camera.putExtra("aspectX", 0);
            camera.putExtra("aspectY", 0);
            camera.putExtra("scale", true);
            camera.putExtra("return-data", false);
