Lesson Learned from building successful android library PhotoEditor: Droidcon Berlin 2021

Benefits

Hassle free coding
Increase efficiency
Easy image editing

Getting Started

To start with this, we need to simply add the dependencies from mavenCentral() in the gradle file of our app module like this

implementation 'com.burhanrashid52:photoeditor:3.0.1'

or we can also import the :photoeditor module from sample for further customization

Migrations

AndroidX

PhotoEditor v.1.0.0 is a migration to androidX and dropping the support of older support library. There are no API changes. If you find any issue migrating to v.1.0.0 , please follow this Guide. If you still facing the issue than you can always rollback to v.0.4.0. Any fix in PR are Welcome :)

Kotlin

PhotoEditor v.2.0.0 is fully migrated to Kotlin. You can use v.1.5.1 for the Java version. There are no breaking API changes in these two versions.

Setting up the View

First we need to add PhotoEditorView in our xml layout

 <ja.burhanrashid52.photoeditor.PhotoEditorView
        android:id="@+id/photoEditorView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:photo_src="@drawable/got_s" />

We can define our drawable or color resource directly using app:photo_src

We can set the image programmatically by getting source from PhotoEditorView which will return a ImageView so that we can load image from resources,file or (Picasso/Glide)

PhotoEditorView mPhotoEditorView = findViewById(R.id.photoEditorView);

mPhotoEditorView.getSource().setImageResource(R.drawable.got);

Building a PhotoEditor

To use the image editing feature we need to build a PhotoEditor which requires a Context and PhotoEditorView which we have to setup in our xml layout

//Use custom font using latest support library
Typeface mTextRobotoTf = ResourcesCompat.getFont(this, R.font.roboto_medium);

//loading font from asset
Typeface mEmojiTypeFace = Typeface.createFromAsset(getAssets(), "emojione-android.ttf");

mPhotoEditor = new PhotoEditor.Builder(this, mPhotoEditorView)
         .setPinchTextScalable(true)
         .setClipSourceImage(true)
         .setDefaultTextTypeface(mTextRobotoTf)
         .setDefaultEmojiTypeface(mEmojiTypeFace)
         .build();

We can customize the properties in the PhotoEditor as per our requirement

Property	Usage
`setPinchTextScalable()`	set false to disable pinch to zoom on text insertion. Default: true.
`setClipSourceImage()`	set true to clip the drawing brush to the source image. Default: false.
`setDefaultTextTypeface()`	set default text font to be added on image
`setDefaultEmojiTypeface()`	set default font specifc to add emojis

That's it we are done with setting up our library

Drawing

We can customize our brush and paint with different set of property. To start drawing on image we need to enable the drawing mode

Type	Method
Enable/Disable	`mPhotoEditor.setBrushDrawingMode(true);`
Shape (brush, line, oval, rectangle, arrow)	`mPhotoEditor.addShape(shape)`
Shape size (px)	`mPhotoEditor.setBrushSize(brushSize)` or through the a ShapeBuilder
Shape opacity (In %)	`mPhotoEditor.setOpacity(opacity)` or through the a ShapeBuilder
Shape color	`mPhotoEditor.setBrushColor(colorCode)` or through the a ShapeBuilder
Brush Eraser	`mPhotoEditor.brushEraser()`

Note: Whenever we set any property of a brush for drawing it will automatically enable the drawing mode

Shapes

We can draw shapes from v.1.5.0. We use ShapeBuilder to define shape and other properties.

val shapeBuilder = ShapeBuilder()
    .withShapeOpacity(100)
    .withShapeType(ShapeType.Oval)
    .withShapeSize(50f);

photoEditor.setShape(mShapeBuilder)

For more details check ShapeBuilder.

Filter Effect

We can apply inbuild filter to the source images using

mPhotoEditor.setFilterEffect(PhotoFilter.BRIGHTNESS);

We can also apply custom effect using Custom.Builder

For more details check Custom Filters

Text

We can add the text with inputText and colorCode like this

mPhotoEditor.addText(inputText, colorCode);

It will take default fonts provided in the builder. If we want different fonts for different text we can set typeface with each text like this

mPhotoEditor.addText(mTypeface,inputText, colorCode);

In order to edit the text we need the view, which we will receive in our PhotoEditor callback. This callback will trigger when we Long Press the added text

mPhotoEditor.setOnPhotoEditorListener(new OnPhotoEditorListener() {
           @Override
           public void onEditTextChangeListener(View rootView, String text, int colorCode) {
               
           }
       });

Now we can edit the text with a view like this

mPhotoEditor.editText(rootView, inputText, colorCode);

If you want more customization on text. Please refer the wiki page for more details.

Emoji

We can add the Emoji by PhotoEditor.getEmojis(getActivity()); which will return a list of emojis unicode.

mPhotoEditor.addEmoji(emojiUnicode);

It will take default fonts provided in the builder. If we want different Emoji fonts for different emoji we can set typeface with each Emoji like this

mPhotoEditor.addEmoji(mEmojiTypeface,emojiUnicode);

Adding Images/Stickers

We need to provide a Bitmap to add our Images mPhotoEditor.addImage(bitmap);

Undo and Redo

  mPhotoEditor.undo();
  mPhotoEditor.redo();

Deleting

For deleting a Text/Emoji/Image we can click on the view to toggle the view highlighter box which will have a close icon. So, by clicking on the icon we can delete the view.

Saving

In v.3.0.0 onward, we can save an image to a file using coroutines:

// Please note that if you call this from a fragment, you should call
// 'viewLifecycleOwner.lifecycleScope.launch' instead.
lifecycleScope.launch {
    val result = photoEditor.saveAsFile(filePath)
    if (result is SaveFileResult.Success) {
        showSnackbar("Image saved!")
    } else {
        showSnackbar("Couldn't save image")
    }
}

You can also save an image to a file from Java. We need to provide a file with callback method when edited image is saved.

 mPhotoEditor.saveAsFile(filePath, new PhotoEditor.OnSaveListener() {
                 @Override
                 public void onSuccess(@NonNull String imagePath) {
                    Log.e("PhotoEditor","Image Saved Successfully");
                 }

                 @Override
                 public void onFailure(@NonNull Exception exception) {
                     Log.e("PhotoEditor","Failed to save Image");
                 }
             });

FAQ

Can I use this library in my app for free?

Yes. It's an open-source library and free to use. If this library has saved your time then showing a little credit will increase my motivation towards making the library better :)

Does it support the CROP feature?

Currently, No. I started to build in branch PE-79. But due to time constraint, I drop the idea. Any PR related to CROP is welcomed :)

Facing issues in applying Filter?

The filter effect is applied using GlSurfaceView and the implementation of this feature causing a lot of issues. Need to think of some other alternative solution. Here is the issue list.

Does is support in other platforms (iOS, Web, Flutter)?

No. Currently, the focus is on making the android library better. We don't have any plans for other Platform.

Other Know Issues

Image Scaling.
Memory Issue in Filter.
