Android Code Camera意图+裁剪图像的说明 [英] Explanation of Android Code Camera Intent + Cropping Images

问题描述

当想要拍照，裁剪并将图像保存在Android应用程序中时，我在Java中使用以下意图...

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); 

以上意图非常有效，但是我的Y和X始终相等.我希望对代码进行分解，以找出指定此内容的内容，以便我可以为自己拍摄并希望裁剪的图像设置可自定义的-最重要的是独立的-X和Y值...

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

注意:不建议使用camera.putExtra("crop", "true"); ... 有关详细信息，请参见上面的注释...方面部分做了但是解决我的问题！

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); 

，因此，将纵横比设置为0而不是1，

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

它们变得彼此独立...

They become independent of each other...

问题解决了！

最终代码

            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);
