I want to put red background (layer 2) on my green object (layer 1). It all looks smooth but after I save as PNG or JPG, black border appears around my green object. How do I get rid of this black border ?
PS. In my photoshop screenshot below, it looks like there's black border too. But in real there's no black border. Image size is 900x900 pixel. I need to use the picture for image processing later so I can't have any other color except for my red & green value.
What I have tried but still fail :
- Save as PNG
- Save for Web and Devices in PNG24
- Save for Web and Devices in PNG2 & unchecked transparency option
- Flatten the image before export to PNG
- Try to change to color mode into Indexed color and then export it
