cPy.cImage module#

class cImage[source]#

Bases: object

Main class for handling raster images.

Provides functionality for creating, loading, manipulating, and querying

image data. Supports various pixel formats, mipmapping, and compression operations.

Designed to be compatible with OpenGL texture uploads.

static CalcImageSize(Format: any, Width: int, Height: int, Depth: int, MipMapCount: int) → int[source]#: Calculates total size in bytes for an image with given parameters.

MipMapsAll: int = 127#: Default max count of mipmaps

Copy(Pixels: any, Format: any, Width: int, Height: int, Depth: int, MipMapCount: int)[source]#: Copies data from a raw buffer.

Set(Pixels: any, Format: any, Width: int, Height: int, Depth: int, MipMapCount: int)[source]#: Sets the image to point to existing memory (or adopts it).

SetHeight(Height: int)[source]#

Create(Format: any, Width: int, Height: int, Depth: int, MipMapCount: int)[source]#: Allocates memory for a new image.

Free()[source]#: Releases the pixel memory.

GetWidth(MipMapLevel: int) → int[source]#

GetHeight(MipMapLevel: int) → int[source]#

GetDepth(MipMapLevel: int) → int[source]#

GetFormat() → any[source]#

GetSize() → int[source]#

GetPixels(MipMapLevel: int) → any[source]#

GetMipMapCount() → int[source]#

GetMipMapCountFromDimensions() → int[source]#

GetDimension() → any[source]#

SwapChannels(Ch0: int, Ch1: int) → bool[source]#

RemoveChannels(KeepCh0: bool, KeepCh1: bool = True, KeepCh2: bool = True, KeepCh3: bool = True) → bool[source]#

InvertChannel(Ch: int) → bool[source]#

CopyChannel(From: int, To: int) → bool[source]#

ToFormat(Format: any) → bool[source]#

Uncompress()[source]#: Dxt3, Dxt5 -> Rgba8

Compress()[source]#: Rgba8 -> Dxt5

ToGrayScale() → bool[source]#: Rgb16, Rgba16 -> R16

ToNormalMap(Format: any, Z: float = 1.0, OldAlpha: bool = False) → bool[source]#: “OldAlpha” works only if(Rgba8 == m_Format && Rgba8 == Format)

CreateMipMaps(MipMapCount: int) → bool[source]#: Generates mipmaps for the image. Not supported for compressed formats.

RemoveMipMaps()[source]#: !Compressed

GetPixelR8(X: int, Y: int) → any[source]#: Returns pixel intensity. Assumes R8 format.

SetPixelR8(X: int, Y: int, p: any)[source]#

MergeRgb8(From: cImage, X: int, Y: int)[source]#

MergeRgba8(From: cImage, X: int, Y: int, ColorAsAlpha: bool)[source]#

Flip() → bool[source]#: Flips the image vertically. Supports Plain, Packed, and Compressed formats.

Resize(Width: int, Height: int) → bool[source]#: Resizes the image using resampling. Plain formats only.

Decrease2X() → bool[source]#: Plain formats && !Cube

MakePowerOfTwo() → bool[source]#: Resizes the image to the nearest power of two dimensions.

Make2D(Square: bool = True, DepthStep: int = 1) → bool[source]#: Converts a 3D volume texture into a 2D strip of slices.

CreateSevenLods(SaveAs: str = 'data/textures/SevenLods.dds')[source]#: Converts 3D texture to 2D set of depth slices
