Save glowing vectors to a PNG with a transparent background

[yakirbu]

Hi,

I have an .eps vector file with glowing sparks,

for some reason, which I have encountered many times before, the glowing vectors always have

black background, so you can't really save them as a transparent PNG image.

I was wondering if you can tell me if I'm doing something wrong, or how,

if it's even possible, can I export it as a transparent image?

An example of my vector file:

Thanks.

EPS does not support transparency... an ai EPS is a combination of an EPS and AI file (if that makes sense) so you would need to modify the objects first in AI and save as an AI file.

Put a black background behind them and save that as any raster format, high resolution.

Then open in Photoshop and use it as an alpha channel:

1. Load the channel as a mask

2. Fill with white on a transparent layer

3. Export as PNG

Here's a video showing the process Monika has described.

Hi,

Is there any way for a colorful glow?

Unfortunately, in the case of color, there is always some black background left.

Im trying get full transparent png from this picture.

After small test :

no blending:

blending screen:

Is it even possible to get a transparent png file to be similar to that of a blending screen?

[Monika Gause]

PNG images can't have the blending mode in them, but glow is always a transparent interaction between foreground object and a specific background. So what works on one background probably doesn't on a different one.

So there is no chance of getting the same effect using a transparent png 😞 There is still mixing.

[Monika Gause]

THose lighting effects are usually achieved by interaction using the screen blend mode. It's not possible in a PNG.

If it's not possible, how was this transparent png done?

It has just been painted in that color. 

But the files being discussed in this thread have been approached differently. 

If you want to start from scratch, you can totally do the second aproach, but you cannot switch approaches in the middle of a project.
