Transparent Image Help
« on: May 15, 2015, 07:32:51 pm »
Hello!

I would like to use SFML to display a partially transparent PNG image.
The one called "shape.png" works fine.
The one called "arrow.png" fails to load.

What is wrong with arrow.png?

"arrow.png" is an 8 bit PNG, which are not supported. Transform it to 24 bit and it should work.

Here's a transformed version:

Using GIMP, I changed the color mode from Indexed to RGB :)

Does it load now?

ImageMagic is also a great tool for transforming images in every-which-way you could dream of (including changing formats easily). Check it out.
