class Geo::GeoV128Texture
A really simple texture where all elements are float vectors.
Functions
| Name | Description |
|---|---|
| ~GeoRefCount() | Virtual destructor required to make sure that the concrete class destructor gets called. |
| AddRef() | Increments the reference count and return new value. |
| ClearToValue(v128) | Clear all pixels in this texture to the given value. |
| CopyUnscaled(GeoV128Texture *, GeoV128Texture *, GeoRect, GeoRect) | Copy a block from one texture to a different texture. |
| CopyUnscaledFromBuffer(v128 *, u32, GeoV128Texture *, GeoRect, GeoRect) | Copies from a buffer of V128s with given pitch, rather than a texture. |
| CopyUnscaledWithDestinationMask(GeoV128Texture *, GeoV128Texture *, GeoRect, GeoRect, GeoV128Texture *) | Copy a block from one texture to a different texture, with a mask specified in the destination texture space. |
| CopyUnscaledWithSourceMask(GeoV128Texture *, GeoV128Texture *, GeoRect, GeoRect, GeoV128Texture *) | Copy a block from one texture to a different texture, with a mask specified in the source texture space. |
| Create(s32, s32) | Create gives you back an uninitialised (values undefined!) texture of the appropriate size with a ref count of 1. |
| DeserialiseFrom(FILE *) | Serialise in and out. |
| Downsample(GeoV128Texture *) | Dest is half the size of source. Takes the average of the four values. |
| DrawRect(s32, s32, s32, s32, v128) | For debugging purposes. |
| Exists(s32, s32) | Return true if [x,y] is contained with the image. |
| GeoRefCount() | Default constructor. The reference count is initially zero. |
| GetHeight() | Return the height of this image. |
| GetPixels() | Return a raw pointer to the start of the pixel array. |
| GetPixels() | Return a const raw pointer to the start of the pixel array. |
| GetWidth() | Return the width of this image. |
| IsValid() | Checks if this texture has valid data. |
| MaskedIn(s32, s32) | Return true if (x, y) is in bounds for this texture, and the value of the x component is positive. |
| MultiplyBy(v128) | Multiply all pixels in this texture by the given value. |
| OutputToPFM(const char *) | Output for debugging purposes. |
| Release() | Decrements the reference count, deleting the object if it reaches zero. |
| Sample(s32, s32) | Return the Sample at position [x,y]. |
| SerialiseTo(FILE *) | Serialise in and out. |
| SetSample(s32, s32, v128) | For debugging purposes. |
Variables

Increments the reference count and return new value.
Returns
New value of reference count.

void Geo::GeoV128Texture::ClearToValue
...
public: void ClearToValue

static bool Geo::GeoV128Texture::CopyUnscaled
...
public: bool CopyUnscaled
(
GeoV128Texture * source,
GeoV128Texture * target,
GeoRect sourceBB,
GeoRect targetBB
)
...
Copy a block from one texture to a different texture.
It expects a one to one correspondence between the pixels in each bounding box - no scaling is applied and it will return false if this isn't met. All parameters must be valid.

static bool Geo::GeoV128Texture::CopyUnscaledFromBuffer
...
public: bool CopyUnscaledFromBuffer
(
v128 * source,
u32 sourcePitch,
GeoV128Texture * target,
GeoRect sourceBB,
GeoRect targetBB
)
...
Copies from a buffer of V128s with given pitch, rather than a texture.
Otherwise the same as CopyUnscaled

GeoRect targetBB,
GeoV128Texture * mask
)
...
Copy a block from one texture to a different texture, with a mask specified in the destination texture space.
Same as CopyUnscaled but only copies where the mask is non-zero in the X co-ord.
