int width,
int height,
int components,
T alpha )

◆ get_oiio_ibuf()

ImBuf * blender::imbuf::get_oiio_ibuf ( ImageInput * in,
const ReadContext & ctx,
ImFileColorSpace & r_colorspace )
static

Get an ImBuf filled in with pixel data and associated metadata using the provided ImageInput.

Definition at line 178 of file openimageio_support.cc.

◆ get_oiio_reader()

unique_ptr< ImageInput > blender::imbuf::get_oiio_reader ( const char * format,
const ImageSpec & config,
Filesystem::IOMemReader & mem_reader,
ImageSpec & r_newspec )
static

Returns an #ImageInput for the precise format requested using the provided #IOMemReader. If successful, the #ImageInput will be opened and ready for operations. Null will be returned if the format was not found or if the open call fails.

◆ imb_create_write_context()

WriteContext blender::imbuf::imb_create_write_context ( const char * file_format,
ImBuf * ibuf,
int flags,
bool prefer_float = true )

Create a WriteContext based on the provided ImBuf and format information.

If the provided ImBuf contains both byte and float buffers, the prefer_float flag controls which buffer to use. By default, if a float buffer exists it will be used.

Definition at line 388 of file openimageio_support.cc.

◆ imb_create_write_spec() [1/2]

OIIO::ImageSpec blender::imbuf::imb_create_write_spec ( const WriteContext & ctx,
int file_channels,
OIIO::TypeDesc data_format )

Returns an #ImageSpec filled in with all common attributes associated with the ImBuf provided as part of the WriteContext.

This includes optional metadata that has been attached to the ImBuf and which should be written to the new file as necessary.

ImBuf * blender::imbuf::imb_oiio_read ( const ReadContext & ctx,
const OIIO::ImageSpec & config,
ImFileColorSpace & r_colorspace,
OIIO::ImageSpec & r_newspec )

The primary method for reading data into an ImBuf.

During the IB_test phase of loading, the colorspace parameter will be populated with the appropriate colorspace name.

Upon return, the r_newspec parameter will contain image format information which can be inspected afterwards if necessary.

◆ imb_oiio_write() [1/2]

◆ imb_oiio_write() [2/2]

bool blender::imbuf::imb_oiio_write ( const WriteContext & ctx,
const char * filepath,
const OIIO::ImageSpec & file_spec )

The primary method for writing data from an ImBuf to either a physical or in-memory destination.

The file_spec parameter will typically come from imb_create_write_spec.
