Hi Jon and Rod:
I have also been working on FS textures, and although I have edited these textures for years using the tools in the Microsoft SDK and photoshop, I am very new to handling them in VB
The texture files use the .bmp extension, but are not typical "Windows Bitmaps"
They are described as DXT1, DXT3 or DXT5 each with slightly different characteristic, but they all have an alpha channel for either transparency or reflectance, and MIP maps.
They can be viewed and converted from one format to another using the SDK utility "Imagetool".
There is an excellent discussion on the web page from Martin Wright located at: http://fly.to/mwgfx/
[u]Some of the formats described are:</u>
DXT1 RGB image, MIPs, the Alpha channel ignored
DXT1a RGB image, MIPs, the current Alpha channel reduced to 1 Bit
DXT3 RGB image, MIPs, the current Alpha channel reduced to 4 bit 16 level)
DXT5 RGB image, MIPs, the current Alpha channel.
(256x256 images use 7 mip maps, 512x512 use 8 mip maps)
Martin's site offers many great tools for viewing, converting and editing these files, designed specifically for MS flight simulator.
He also can provide a developers package with support for his .dll with routines to load almost any format image, create MIP maps, and alpha channel and save to any of the FS formats.
ROD: I have obtained the develper files, but none of the books I have purchased, including yours, show a Newbie
step by step how to incorporate a 3rd party .dll into my project.
I have documention for the called routines and parameters, but where do I put the files, and how do I declare them?
The files in the folder provided are of the types:
.dll, .bas, .frm, .frx, .scc, .vbp, and .vbw
Note: the dll was written in C++, but the above files were written for VB6. Can we use them in .net?
