DDS_ALPHA_MODE_UNKNOWN (0) - This is the default for most.This can be one of the following values to return information about the alpha channel if present in the file: The last optional parameter alphaMode is a pointer to return the alpha mode of the.

Quality is obtained by generating mipmaps offline and storing your textures as. If loading a textureįrom a file without mipmaps you can get a quick & dirty filter solution by using auto-gen.
#Directx11.1 and opengl 4.4 driver
Some formatsĪre not supported by the driver which will default to a texture without mips. If d3dContext is nullptr, then it functions the same as the version which does not take a context.Īuto-gen mipmaps have limited utility because the quality of the mips can vary widely.
Also if a context is passed, the function is not thread safe. Note the quality of auto-gen mipmaps is up to the driver, so can vary widely. If a d3dContext is given to these functions, they will attempt to use the auto-generation of mipmaps features in the Direct3D 11 API if supported for the pixel format. dds texture file, but this provides a simple scaling solution by default.

The full file is still required in memory, so it would be more efficient in terms of load-time to dds file of a 16k by 16k texture with all mipmaps, and it will still loadĮven on a feature level 9.1 device by skipping all the mipmap sizes that are too large for the hardware to The reason for the default maxsize behavior with 0 is to automatically handle Direct3D feature level scaling. If '0', then if the attempt to create the Direct3D 11 resource fails and there are mipmaps present, it will retry assuming a maxsize based on the device's current feature level. If maxsize parameter non-zero, then all mipmap levels larger than the maxsize are ignored before creating the Direct3D 11 resource. HRESULT CreateDDSTextureFromFileEx(ID3D11Device* d3dDevice,ĭDS_ALPHA_MODE* alphaMode = nullptr) ParametersĮither texture or textureView can be nullptr, but not both.

Note that no pixel data conversion takes place. This will force return format be one of the of DXGI_FORMAT_*_SRGB formats if it exist. There is also a forceSRGB option for working around gamma issues with content that is in the sRGB or similar color space but is not encoded explicitly as an SRGB format.
The standard routines default to D3D11_USAGE_DEFAULT, D3D11_BIND_SHADER_RESOURCE, 0, and 0 respectively.įor cubemaps, the miscellaneous flags default to D3D11_RESOURCE_MISC_TEXTURECUBE.įor auto-gen mipmaps, the default binding flags are D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_RENDER_TARGET and miscellaneous flags is set to D3D11_RESOURCE_MISC_GENERATE_MIPS. These versions provide explicit control over the created resource's usage, binding flags, CPU access flags, and miscellaneous flags for advanced / expert scenarios.
