Using web transparency

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am updating src/using/web.xml and I found a paragraph that feels very 
wrong.

http://docs.gimp.org/2.6/en/gimp-using-web-transparency.html

To point out my complaint, consider:

Step 1: use wilber image

Step 2: Verify you have an alpha channel

The next step, things feel very wrong:

Step 3: You can now remove the background layer to get a completely 
transparent background, or create a gradient from color to transparency. 
You are only limited by your imagination. To demonstrate the 
capabilities of alpha transparency, we'll make a soft glow in the 
background around our Wilber.

********* Complaints:


Complaint 1:

"You can now remove the background layer to get a completely transparent 
background"

I do not have a background layer to remove. The image 
(http://docs.gimp.org/2.6/en/images/using/preparing_for_web1.png) has 
only one layer named background, which includes Wilber and the 
background. I assume that this means that I can use an erase to erase 
the blue and white background.

Complaint 2:

"create a gradient from color to transparency."

This has not yet been covered in the documentation (up to this point). I 
do see a menu option for Colors > Colors to alpha, but I am not clear 
how this helps me obtain the soft glow in the background around Wilber.

Complaint 3:

"To demonstrate the capabilities of alpha transparency, we'll make a 
soft glow in the background around our Wilber."

I suppose that this should read:

"To demonstrate the capabilities of alpha transparency, the author used 
transparency to make a soft glow in the background around our Wilber."

I have no idea how to cause this effect.

******************

If anyone has an opinion on this section, please say so, otherwise, I 
will make radical changes to this one paragraph.
