How have you edited it? Have you added layers or converted it to 16 bits?

Hi,
What are Targas used for?
Thanks,
Ron

my husband uses them to make files for his NASCAR race sim
you can paint cars in a PS layered template but they have to be flattened
and save as >>tga to be seen in the game interface

Targa-format files are commonly used for texture maps for 3D modeling
and rendering applications. A Targa file can contain an alpha channel
which controls transparency, and the rendering program "paints" a 3D
image by wrapping the Targa file around it. Transparent areas of the
targa file show the 3D model beneath.

Hi,
Is the alpha channel the same thing as a displacement map? Can an
alpha channel used for transparency information also be used for
displacement information at the same time? Do Targas only allow for a
single alpha channel?

Thanks,
Ron

Nope. Different animals completely. Alpha indicates per pixel transparency.
In 8 bit 255 means 100% opaque. A displacement map is a per pixel value to
shift the location of the pixel, remaping the image to a new, usually
warped, shape.If two values are used, you can displace in two dimensions.

I suppose it's possible, but it's probably never done. The edges of an
object will have an alpha less than 100%, and this would cause those pixels
to be displaced less than pixels in the middle of the object. The result
would be a sort of skewed "punch out" of the object. It's more common to
use modified brightness information as a displacement map. One example is
a wavy flag effect where the waves correspond to the shaded colors of the
flag.

> Do Targas only allow for a single alpha channel?

I believe so. Targa got in there first with high quality video overlays for
the PC, so some of their file formats are still being used. The file format
itself is a dead end.

I see. It seems like any image format worth its salt would include a
transparency channel. And maybe a few map channels too.
Come to think of it, PSD and TIF are some pretty powerful protocols to
be able to contain all the color, style, layer, text, vector and
channel information that PS generates.

Thanks,
Ron

This is only the 2D stuff too. Wait til you start digging into the
rendering side of things. It's the difference between understanding the
opcode set of a simple machine, versus an OS.
