filterRect (LColor color, float min_u, float min_v, float max_u, float max_v) | |
Fills "color" with the average RGBA color of the texels within the rectangle defined by the specified coordinate range. More... | |
filterRect (LColor color, float min_u, float min_v, float min_w, float max_u, float max_v, float max_w) | |
Fills "color" with the average RGBA color of the texels within the rectangle defined by the specified coordinate range. More... | |
int | getXSize () |
Returns the width of the texture image that is contributing to the TexturePeeker's information. This may be either the Texture's full width, or its simple ram image's width. More... | |
int | getYSize () |
Returns the height of the texture image that is contributing to the TexturePeeker's information. This may be either the Texture's full height, or its simple ram image's height. More... | |
int | getZSize () |
Returns the depth of the texture image that is contributing to the TexturePeeker's information. More... | |
lookup (LColor color, float u, float v) | |
Fills "color" with the RGBA color of the texel at point (u, v). More... | |
lookup (LColor color, float u, float v, float w) | |
Fills "color" with the RGBA color of the texel at point (u, v, w). More... | |
![]() | |
int | getRefCount () |
Returns the current reference count. More... | |
ref () | |
Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More... | |
bool | testRefCountIntegrity () |
Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More... | |
bool | testRefCountNonzero () |
Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More... | |
bool | unref () |
Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More... | |

filterRect | ( | LColor | color, |
float | min_u, | ||
float | min_v, | ||
float | max_u, | ||
float | max_v | ||
) |
Fills "color" with the average RGBA color of the texels within the rectangle defined by the specified coordinate range.
The texel color is linearly filtered over the entire region. u, v, and w will wrap around regardless of the texture's wrap mode.

Fills "color" with the average RGBA color of the texels within the rectangle defined by the specified coordinate range.
The texel color is linearly filtered over the entire region. u, v, and w will wrap around regardless of the texture's wrap mode.
int getXSize | ( | ) |
Returns the width of the texture image that is contributing to the TexturePeeker's information. This may be either the Texture's full width, or its simple ram image's width.
int getYSize | ( | ) |
Returns the height of the texture image that is contributing to the TexturePeeker's information. This may be either the Texture's full height, or its simple ram image's height.
int getZSize | ( | ) |
Returns the depth of the texture image that is contributing to the TexturePeeker's information.
lookup | ( | LColor | color, |
float | u, | ||
float | v | ||
) |
Fills "color" with the RGBA color of the texel at point (u, v).
The texel color is determined via nearest-point sampling (no filtering of adjacent pixels), regardless of the filter type associated with the texture. u, v, and w will wrap around regardless of the texture's wrap mode.
