Hello Gaurav,

I really like your work and your example. Thanks for sharing us this example.

Now I want to ask you that, is it possible to undo/redo of filled color ? If i want to go to back few steps and then paint again ? Is it possible ?

Waiting for your answer.
Thanks

I feel like I'm taking crazy pills but I'm getting color data with green and alpha switched.
I'm running this on iPad Pro with iOS11, loading a rgb color png photo.

This method shows switched values for green and alpha.

`unsigned int getColorCode (unsigned int byteIndex, unsigned char *imageData)
{
unsigned int red = imageData[byteIndex];
unsigned int green = imageData[byteIndex + 1];
unsigned int blue = imageData[byteIndex + 2];
unsigned int alpha = imageData[byteIndex + 3];

return (red << 24) | (green << 16) | (blue << 8) | alpha;

}`

Green is always 255 and alpha is the green value.

Same results on iPad simulator running iOS11.

Any ideas?
