DDS and DrawImage

[Gabriel]

Hello,

I have a bitmap that I want to display with the transparancy. I use "Paint.net" when I backup my file Screen.dds (DXT5) my image to the screen is black! I try with "and paintshop plugin nvidia" then "MakeDDS" and it is alway the same thing!

 

Mais le plus vexant "doors1.dds" fonctionne tres bien. sauf si je l'edite ou le converti avec "MakeDDS.exe"

 

Some can give me a little color in my code;-)?

 

TTexture m_ScreenMask=LoadTexture ("abstract::Screen.dds");
..

{
UpdateFramework();
RenderFramework();
SetBlend(1);
DrawImage( m_ScreenMask,0,0,1280,1024);
SetBlend(0);
Flip(0);
}

What format are you saving your image in before converting to .dds.

 

If you want alpha you need to save as .tga files

hi,

 

i try now with tga (save as tga) , but LoadTexture retun NULL with "Screen.tga"

 

Thank

[Road Kill Kenny]

no you need to make your textures .tga and then convert the tga to .dds

 

.bmp and .jpeg don't have an alpha channel. So when you convert .bmp and .jpeg to a .dds you won't have an alpha channel

My Link !

 

Thank

You can also use png, because tga files are insanely huge, since they have no lossless compression.

When you save as dds, you need to export mipmaps also, else the texture will be completely black in LE2.

I'm not sure I can use the command LoadTexture with png or tga! I think the only DDS I do not return an error with this API.

 

 

I also i try "mips map option", but always black

 

Which can test the file and tell me if he can see the image completely black?

 

thank you

Works fine for me in Blitzmax...

 

 

[Gabriel]

hooo ?

 

you use the same code ?

 

TTexture m_ScreenMask=LoadTexture ("abstract::Screen.dds");
..
{
UpdateFramework();
RenderFramework();
SetBlend(1);
DrawImage( m_ScreenMask,0,0,1280,1024);
SetBlend(0);
Flip(0);
}

[Gabriel]

i have this result :-( !!!

works fine in lua as well...

 

perhaps you are not loading the file you think is being loaded? by chance do you have multiple files with the same name or perhaps you have changed the file since you uploaded? because the one you provided works fine...

[Marleys Ghost]

I tried your texture in two apps written in Blizmax using LE, one using framework the other not, and it was fine in both.

[Gabriel]

Hoho here is a very pertinent remark, I rename the file and it works indeed ^ ^

I must be deeply stupid ^^, a week that leaves nothing good to predict for me!

 

Again thank you all
