TTextureFilterHelper

TPixelFormatExHelper

Helper class for managing pixelformats. It exists a platform specific implementation to convert Delphi enum type to platform specific value.

TGorillaTextureWrapHelper

Helper class to convert TGorillaTextureWrap type to a platform (OpenGL, Metal, ...) specific value.

Members

TGorillaTextureDataTypeHelper

Helper class to convert TGorillaTextureDataType to a platform (OpenGL, Metal, ...) specific value and to a string value.

Ancestors

Members

TGorillaTexture

Extends the internal FMX texture class with more configuration opportunities to initialize a texture.

Remarks

The parent bitmap should be a TGorillaTextureBitmap instance, otherwise default values will be used for extended fields like WrapS, WrapT, ...

TTextureBitmapPrivateAccess

Helper class for implicit type conversion to access the private FTexture field.

TGorillaTextureBitmap

Overrides the FMX texture bitmap component to allow more opportunities to configure texture (format, min-, magfilter, wrapping, datatype, ...) The basic problem with the FMX implementation is, that it uses fixed values for textures. This is not usable for usage in render passes, where a specific type of texture is expected, f.e. for shadow mapping.

Remarks

Because in render passes we create a TTextureBitmap / TGorillaTextureBitmap we need to store texture settings here, to apply them to the automatically created texture instance.
