Image Presets - Removing Background off of an image that has an alpha channel

Avatar

Level 1

Hi, 

I am having trouble configuring an image preset that allows me to modify the background of a TIFF image to become transparent.

This image is stored as a TIFF in Adobe Experience Manager and contains multiple layers to it. The image file has an alpha channel layer that I thought I could manipulate to change but for some reason when I am trying to render it it is not working.

 

I'd like to have two different image presents with the following formats:

1. Format = PNG with Alpha

2. Format = TIFF with Alpha

 

I've tried the color and bgColor modifiers with the default of 0,0,0,0 but the image does not seem to remove the background at all.

I'm a bit new to this thus any type of information would help! 

 

Sample image can be found here:

hi,

 

If you upload an asset which is transparent then using fmt=png-alpha or fmt=png will give transparent image but if uploaded image is not transparent then using fmt will not give transparent image. 

 

We can remove background while uploading the image and steps can be found in below link under section "Knockout Background"
