Outline Introduction System Architecture Implementation

Introduction > Capturing a best picture without any hurdles is quite difficult. Sometimes excessive sunlight make the picture too bright or we capture picture in moist atmosphere that makes the picture blurry. Also, picture taken with flash light gives the yellowish look to picture. Hence, we need to edit picture to enhance light and color , to fix the sharpness and brightness, to crop the unnecessary part also to have fun by adding stickers or frames. > Considering this reason as a motivation, I created an android mobile application that enhances the quality of the captured picture. My application is consisting of the following image editing features: Image cropping Image filtering Adjusting brightness, exposure, clarity and contrast Adding text, stickers, frames Adjusting focus >In addition to that, my application captures picture with front and rear camera. We can also import picture from internal memory and we can export edited picture to the external memory of phone via application.

Fragments A Fragment represents a behavior or a portion of user interface in an Activity. You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a "sub activity" that you can reuse in different activities).

SVG Files Scalable Vector Graphics (SVG) is an XML-based vector image format for two-dimensional graphics with support for interactivity and animation. SVG describes how the image should appear. An SVG file can be scaled to different sizes without losing quality - in other words, the format is resolution independent. SVG images and their behaviors are defined in XML text files.

Intent An Intent is a messaging object you can use to request an action from another app component. Intents communicates between components in several ways, I have used “on start activity” Communication medium. There are two types of intents: Explicit intents specify the component to start by name (the fully-qualified class name). You'll typically use an explicit intent to start a component in your own app, because you know the class name of the activity or service you want to start. For example, you can start a new activity in response to a user action or start a service to download a file in the background. Implicit intents do not name a specific component, but instead declare a general action to perform, which allows a component from another app to handle it. For example, if you want to show the user a location on a map, you can use an implicit intent to request that another capable app show a specified location on a map.

Let’s review some concepts Cropping Cropping of image is done by line clipping algoritham Filters All Filters and effects work due to RGB color Model Text,Stickers,Frame By using Fragments we can reuse and create the Text, Stickers and Frame AnimatorSet animatorSet = new AnimatorSet(); animatorSet.playTogether(new Animator[]{ObjectAnimator.ofFloat(panelView, "alpha", new float[]{1.0F, 0.0F}), ObjectAnimator.ofFloat(panelView, "translationY", new float[]{0.0F, (float)this.listView.getHeight()})}); animatorSet.addListener(new SetHardwareAnimatedViews(panelView, new View[0])); animatorSet.setDuration(300L); return animatorSet;

Too much of theory Time For Live Demo !!!!

Thanks! Any questions?
