android - Apply multiple effect on bitmap without saving it -

my requirement load multiple effect on bitmap. following apply-effects-on-image-using-effects it. got success applying effect requirements give brightness effect separately. means user can able give brightness effect after applying other effect without saving file.

i know after saving file , render file again makes possible. need without saving image file.

right now, if apply brightness on applied effect applied effect gone , brightness shows effect. because of below code:

meffect = effectfactory.createeffect(effectfactory.effect_brightness); 

here, meffect initialize give new effect on texture. without not able load effect.

so, question is, how load multiple effect on same texture without saving it.

create 3 textures, instead of 2:

private int[] mtextures = new int[3];  private void loadtextures() {     // generate textures     gles20.glgentextures(3, mtextures, 0);     ... 

after that, can apply sequentially 2 effects 1 after another, that:

private void applyeffect() {     if (mneedsecondeffect) {        meffect.apply(mtextures[0], mimagewidth, mimageheight, mtextures[2]);        msecondeffect.apply(mtextures[2], mimagewidth, mimageheight, mtextures[1]);     } else {        meffect.apply(mtextures[0], mimagewidth, mimageheight, mtextures[1]);     } } 

using 2 textures effects can apply cascade of amount of effects, changing source , destination textures.

edit multiple effects try this:

let's imagine have array of effects cascade

 effect meffectarray[] = ...; // effect objects applied  int meffectcount = ... ; // number of effects used right output  

then applyeffect() method this:

private void applyeffect() {     if (meffectcount > 0) { // if there effect         meffectarray[0].apply(mtextures[0], mimagewidth, mimageheight, mtextures[1]); // apply first effect         (int = 1; < meffectcount; i++) { // if more 1 effect             int sourcetexture = mtextures[1];              int destinationtexture = mtextures[2];             meffectarray[i].apply(sourcetexture, mimagewidth, mimageheight, destinationtexture);             mtextures[1] = destinationtexture; // changing textures array, 1 texture output,              mtextures[2] = sourcetexture; // 2 sparse texture         }     } }
