[wiki]Startup_lumps[/wiki]The Wiki wrote: Hexen
Hexen uses a lump called STARTUP to show a 4-bit, 16-color, 640×480 picture on the startup screen. It is stored in a custom, non-standard format: the first 48 bytes are for the 16 color palette (three bytes per color entry), followed by raw 4-bit planar graphics. The total size is therefore 153648 bytes exactly. The music lump "ORB" is played during loading.
The pixels from [64,441] to [576,464] are used to display the status bar, with hardcoded "notch" graphics. Each time one is drawn, the sound "StartupTick" is played.
The notches can be replaced by raw 4-bit bitmaps. The loading notch is 16×23 (184 bytes) and called NOTCH and the netgame waiting notch is 4×16 (32) and called NETNOTCH. They use the palette defined in STARTUP.
SLADE3 is the only image editing tool currently available that can convert pictures to these formats and create replacement graphics for them.
Spoiler:Then I import a PNG (I've tried with a few, in a few different formats, including the original Hexen PNG that Slade exported). Then I select the image and pick the convert to option. Additional options are enabled:
Spoiler:That's where my first query arises. I got the impression from the Wiki article that the image contains its own palette:"the first 48 bytes are for the 16 color palette". However, whenever I pick this option, it seems to try to convert the palette to whichever game palette is loaded. Even leaving it on "Existing/Global" changes the colours in my image (and I have tried with an image already reduced to the 16 colours that I wanted - and Slade kept changing them).
Spoiler:Aaaanyway, I convert the image and my second query arises. The lump list in Slade still lists the graphic as a PNG. Surely it should now be saying "Planar"?

Spoiler:So, here's the procedure that "works" for me:
That may be related to fact that it's a JPG.Gez wrote:Cannot convert to planar format, too many colors (33)
Did someone get this working yet?Enjay wrote:Choose a palette that is close to the one that I want in the image (because I fail at getting Slade to use the palette in the image)
