Can’t save transparent PNG 24 in Fireworks?
24 bit PNG’s don’t have transparency. A 24 bit PNG has 3 channels – Red, Green, and Blue. In a 32 bit PNG you have 4 channels – Red, Green, Blue and Alpha, so the way to save a transparent PNG with high quality anti aliasing in Fireworks is to save it in 32 Bit mode.
But Photoshop doest it!
That’s because Photoshop says it saves in 24 bit when it’s actually saving as 32 bit.
My name is Luís Alves, I'm 37 years old and I'm a Designer. I have been dedicating my life to art and design since the age of 15 and in the latest 8 years webdesign has been my main activity.
Can you explain this? How could Adobe make this mistake?
So it looks like in Photoshop they don’t consider the 8 alpha bits in the naming of the png so call it 24. In Fireworks they consider red, blue, green and alpha 8*4 so 32 bit.
This is interesting.
