Pal2pac.dll texture handling

**Dschulle** · Jan 28 2004, 19:04

I don't want to keep this cool info away from you, even if most editors might have no use for it.
The Pal2Pac.dll is included with O2. The rest of the info is inside the header.

Big THX to SUMA! ***

Could you provide me with a header file? Or give me the complete function call of "CreateTexture" and "CombineTexture".

Here you are:

If you think anyone else can use this for the benefit of OPF community, feel free to share it. You can create and load pal/pac files with this interface. It is far from flexible, but it may help you.

OK, explain the use of this for a dummy like me. Will it make pac files "better"? Will it allow people to make batch converters? etc?

**shinRaiden** · Jan 29 2004, 03:53

There really ain't a thread for this...

Basicly, this is the critical core code for exporting graphics into OFP PAA/PAC format. If you want to make a converter like texview, or create a viewer application, or a wrp editor, this is the key to WRITING textures.

Essentially, this is just the skeleton _defs and code to structure your data arrays of pixels, and properly process them through the pal2pac.dll included with Oxygen.

The biggest need that can now be filled is to make a transition masher, where you could load in some base textures, a list of desired transitions, and punch out textures. Or you could make a converter for other raw formats.

well, my dream tool is a batch converter for taking a whole folder of tgas and converting them to paa or pac... hope someone makes one now

**Dwarden** · Jan 29 2004, 05:59

I got idea, can someone made .paa .pac plugin for IrfanView?

You allready can do this with the pal2pace.exe you find in your Bulldozer folder:

pal2pace *.tga

Unfortunately this header file doesn't enable us to write a better textur converter than texView since the dll encapsulates the function for the texture compression and the file headers for the texture files are still unknown so that you can't write your own compression function.

But it makes it much easier for tools like WrpTool to read and write OFP textures.

I think O2 Doc will suit best for this topic.

Currently Dschulle is trying to integrate the pal2pac.dll into PaNSee, the texture browser that comes with WrpTool.

We are also looking into writing a plugin for Photoshop (and programs who can also use PS-plugins like PSP and others), but the problem is that pal2pac needs file names and writes the files by itself wich isn't the way a PS-plugin should handle it.
A PS-plugin only gets a buffer to write the data into, while PS handles all the file creating and opening stuff, you don't even get the filename from Photoshop.

So what we would need for this is basically the source code of the pal2pac.dll or some info about the texture file headers of paa and pac files (just the header info, we allready know the different formats for the texture data and how to write/read it)
