Login screen bitmap transparancy

[Maelstorm]

Does the login screen support transparencies? It seems that according to CorelDRAW, BMP files don't support alpha-channel transparencies. GIF files do, so I'm wondering if I can use a GIF file in place of a BMP file for the Logo Picture.

no you can't use .gif instead of the .bmp format.

but yes, .bmp support transparencies as long as it was saved like 32bit format. you can use an alpha layer that will do a good transperency effect.

So what software supports a 32-bit BMP? I have CorelDRAW 12, but it does not have a option to select a 32-bit BMP...That I'm aware of....

i'm not such a geek at corel but with photoshop when you save the image it asks you to select ... 16bit/24bit/32bit ... and rle compression.

There is no documentation on how to do this in Corel, so I submitted a support request, so we will see what happens.

The best way to do it is to save it as 32-bit PNG.

Then open it in MS Paint and immediately save it as a 24-bit BMP. But it will actually save it as a 32-bit BMP. You can check this in the file properties. I've done this and it works fine (for making Visual Styles).

The transparency in BMP32 appears black when you view it in most programs.

The logon screen does support transparencys.

BUT you cannot change the ile format.

heres what you do

examples

transparent background

background: argb(0,0,0,0)

transparent images

background: rcbmp(126,6,X,0,0,1,0)

X is the #RRBBGG code (must have the #)

Scripting is hard. - remember you can make

Background: rgb (x,x,x) to

Background: argb(x,x,x,x)

Background: rcbmp(x,x,x,0,0,1,0)

and visa-versa

I have successfully comleted the best looking most pro looking bug free logonui.

The logon screen does support transparencys.

<{POST_SNAPBACK}>

that's not totally true

if you check xpize logon you'll see that 32bit bitmaps have transparencies / translucent areas

Windows automatically view Maganeta as transparent, this includes bitmaps and pngs, gifs to.

Howwever in the logonui script, you need to specify what color is transparent, most defualts r magenta.

You have to understand the script in order to have a proper working good looking and non buggy logonui.exe

Your better off not changing the file formats. It does mess up the logonui.

to be concrete, on a 256 colors bitmap, pink (255,0,255) will be used as the mask (aka transparent color) if first and last pixels of the image are of that color. i.e. a 256 colors 300x300 image with pixels 1,1 and 300,300 of the same pink color (255,0,255) will be totally transparent.

over the logonui you'll also need to point which color is transparent on the uitext, by default already mentioned pink.

btw, with that method you won't be able to use translucent areas. to achieve this, is necessary a 32bits image with an alpha channel. for this you can use PS, PSP, the gimp or other advanced graphical tool

hope this to be enough clear as i've seen the forum filled with similar questions

Can someone HELP me?

I am trying to make my Boot Screen look like the one , but when Windows is booting up it is showing up as these LAST_SESSION.INI with distorted colors. Which file I need to edit in the Windows XP Pro CD and what do I need to do to correct this problem?
