Dear RagnarokStack,

I have used your library android-image-filter. It is very helpful and good implemented. Thanks a lot!

But filters leave a small border around an image untouched, how to solve this problem?

Sincerely, Y.P.

When applying the oil style to a big image (ImageView of size of screen) it doesn't apply the effect to the whole picture as seen here:

where you can see that the bottom of the image its still normal.

I download your 'android-image-filter' file and it didn't show any error. But when I click 'Select an image' and choose one from my gallery, it can't show the image. It shows 'Please select an image' after I click a filter. And I install the apk, still can't show any image.

Caused by: java.lang.UnsatisfiedLinkError: No implementation found for int[] com.example.jigneshjc.portraphoto.portra_FILTER.NativeFilterFunc.oilFilter(int[], int, int, int) (tried Java_com_example_jigneshjc_portraphoto_portra_1FILTER_NativeFilterFunc_oilFilter and Java_com_example_jigneshjc_portraphoto_portra_1FILTER_NativeFilterFunc_oilFilter___3IIII) at com.example.jigneshjc.portraphoto.portra_FILTER.NativeFilterFunc.oilFilter(Native Method) at com.example.jigneshjc.portraphoto.portra_FILTER.OilFilter.changeToOil(OilFilter.java:21) at com.example.jigneshjc.portraphoto.portra_FILTER.BitmapFilter.changeStyle(BitmapFilter.java:36)

Hi!

Now Android Studio (1.5.1) supports very well NDK. I am able to import it, but I cannot found a way to import this project as a library or AAR file. I think it is not difficult to do it so you can add information about how to compile it. Thankyou!

Firstly, your work really helps a lot and thank you very much!

I have checked all the filters, it seems that there is no related filter to Bilateral Filter. Is it because I didn't find the proper name or this library does not support bilateral filter?

When I apply Gaussian Blur to a bitmap with alpha channel, the alpha channel changes to black. While the alpha channel is good if I use RenderScript. Is it possible to keep the alpha channel in the filtering process?

attempting to use public static final int SOFT_GLOW_STYLE = 16; // soft glow as a filter makes the app crash returning this in the LogCat:

I added this library to my projects, it works properly on some devices but it does not on some others. System.loadLibrary line, throws an exception because library cannot be loaded. I unzip the apk and check libAndroidImageFilter.so is created for all architecture.

There is no common among problematic devices. Some of them are KitKat whereas some other are JellyBean. Most of them are Samsung but there are also several HTC. Also there are a Samsung devices which does not have any crash. Furthermore, even though all of them has armv7 based cpu, there are a few armv7 based devices on which the library is able to run.

In short, I have no idea why it crashes on some devices.

Hi, First of all, thank you for the great job on this. I am trying it out thru the demo app in this project.

However, eveytime when I apply an effect then the demo app stops unexpectedly.

Here are some examples of what I got when the unexpected stop happens:

1. Select the LOMO effect in the items menu to apply the LOMO effect. The code goes all the way to the line:47 in cn.Ragnarok.LomoFilter.changeToLomo, which calls NativeFilterFunc.lomoAddBlckRound to get int[] resultPixels. Then, suddenly the demo app stops to cease. The logcat outputs 2 msg:

• E/dalvikvm(31965): VM aborting
• A/libc(31965): Fatal signal 6 (SIGABRT) at 0x00007cdd (code=-6), thread 31965 (imagefilterdemo)

2. This time, try the Relief effect. The code goes untill the line:24 in cn.Ragnarok.ReliefFilter.changeToRelief, which calls Bitmap.createBitmap to get Bitmap returnBitmap. The logcat outputs:

• E/AndroidRuntime(324): FATAL EXCEPTION: main

Could the memory cause this issue ? What could the root cause ?

Thank you
