Android image processing gpuimage for Android

Gpuimage is the next open source GPU-based image processing library in iOS, offering a wide range of image processing filters and supports real-time filters for cameras and cameras. Gpuimage for Android is its implementation under Android, also open source, hosted on GitHub.

Version: android-gpuimage-1.1.1

OpenGL ES 2.0 is not supported on Android emulator so it will be error-genymotion test, or real machine running.

Reference caused By:java.lang.IllegalStateException:OpenGL ES 2.0 is not supported on the this phone.

(1) using a custom ImageView
XML code

<jp.co.cyberagent.android.gpuimage.gpuimageview    android:id= "@+id/gpuimage"    android:layout_width= " Wrap_content "    android:layout_height=" 0DP "    android:layout_gravity=" center "    android:layout_weight=" 1 "/>

Java code

Mimageview.setfilter (New Gpuimagesepiafilter ()); Sepiamimageview.setfilter (New Gpuimagegrayscalefilter ()); Graymimageview.setfilter (New Gpuimagesharpenfilter ()); Sharpmimageview.setfilter (New Gpuimagesobeledgedetection ()); Edge

(2) Working with files in assets

Java code

Read image Assetmanager as = Getassets (); InputStream is = null;    Bitmap Bitmap = null;try {is = As.open ("dog.jpg");    Bitmap = Bitmapfactory.decodestream (IS); Is.close ();} catch (IOException e) {log.e ("mainactivity", "Error"),}//using gpuimage processing image gpuimage Gpuimage = new Gpuimage (this); Gpuima Ge.setimage (bitmap); Gpuimage.setfilter (new Gpuimagetoonfilter ()); bitmap = Gpuimage.getbitmapwithfilterapplied (); Display the processed image in ImageView ImageView view = new ImageView (this); View.setimagebitmap (bitmap); Setcontentview (view);

(3) using Photoshop's ACV file
Java code

Read image Assetmanager as = Getassets (); InputStream is = null;    Bitmap Bitmap = null;try {is = As.open ("dog.jpg");    Bitmap = Bitmapfactory.decodestream (IS); Is.close ();} catch (IOException e) {log.e ("mainactivity", "Error");} Read Photoshop's ACV file gpuimagetonecurvefilter filter = new Gpuimagetonecurvefilter (); try {is = As.open ("TONE_CURVE.ACV")    ;    Filter.setfromcurvefileinputstream (IS); Is.close ();} catch (IOException e) {log.e ("mainactivity", "Error");} Use Gpuimage to process images gpuimage gpuimage = new gpuimage (self); gpuimage.setimage (bitmap); Gpuimage.setfilter (filter); bitmap = Gpuimage.getbitmapwithfilterapplied ();//Display the processed image in ImageView ImageView view = new ImageView (self); View.setimagebitmap (bitmap); Setcontentview (view);
