I’m not sure I understand the SDL_ConvertSurface function. The
documentation says it “Converts a surface to the same format as another
surface.” But it also says, “Creates a new surface of the specified
format,”. How can you convert a surface that’s new?

Essentially what I need to do is to upconvert a surface containing a 24
bpp image to 32 bpp in order, I think, to blit it properly to my
layout.

Advice please.

Thanks,
Lilith

Hello !

I’m not sure I understand the SDL_ConvertSurface function. The
documentation says it “Converts a surface to the same format as another
surface.” But it also says, “Creates a new surface of the specified
format,”. How can you convert a surface that’s new?

This means it converts a surface to another format,
by creating a new Surface with the wanted format and
blit the old surface contents to the new surface.

One reason for using the same format across
surfaces is simple the blitting speed is better.

Okay, so the format that I point to, in this instance, would be the
format of the 32 bpp surface I’m eventually looking to blit to?

Thanks,
Lilith

i’m not sure if i’ve bugged you lot about this before, take space invaders for
example, it has a black background on most of the screen, so if you could make
all the blank/black parts of the screen a mp3 visualization, you can play space
invaders with some funky music and pictures, space invaders is even only two
colors, so you could have one visualisation for the black one for the white. if
that makes any sence.----------------------------------------------------------------
