D3D9 Volume Tex bytes in box computed incorrectly #281

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Checked out June 16 and observed this when locking 512x512xN size tex. 
This may only be noticed for large size textures because the result had 
wrapped to a negative value.

In both VolumeTexture::LockBox functions:

ORIGINAL:
int lockedSize = lockedBox.RowPitch * lockedBox.SlicePitch * 
GetLevelDescription( level ).Height;

FIXED:
int lockedSize = lockedBox.SlicePitch * GetLevelDescription( level ).Depth;
