Parameters: In: inFileName - Pointer to a null-terminated string that specifies the file name. inCreateDisposition - Action to take on files that exist, and which action to take when files do not exist. inDesiredAccess - Access to the stream (reading, writing, or both). Out: outStream - The reference of the stream. Returns: Returns EDS_ERR_OK if successful.

In the case of writing in excess of the allocated buffer size, the memory is automatically extended. Parameters: In: inBufferSize - Number of bytes of the memory to allocate.

Parameters: In: inUserBuffer - Pointer to the buffer you have prepared inBufferSize - Number of bytes of the memory to allocate. Out: outStream - The reference of the stream.

As the EDSDK automatically resizes the buffer, the memory stream provides you with the same access methods as for the file stream. If access is attempted that is excessive with regard to the buffer size for the stream, data before the required buffer size is allocated is copied internally, and new writing occurs. Thus, the buffer pointer might be switched on an unknown timing. Caution in use is therefore advised. Parameters: In: inStream - object to memory stream Out: outPointer - Pointer to valueable stored the pointer Returns: Returns EDS_ERR_OK if successful.

An event is received as notification of progress during processing that takes a relatively long time, such as downloading files from a remote camera. If you register the callback function, the EDSDK calls the callback function during execution or on completion of the following APIs This timing can be used in updating on-screen progress bars, for example. APIs : EdsCopyData, EdsDownload, EdsGetImage Parameters: In: inRef - The reference of the stream or image. inProgressCallback - Pointer to a progress callback function. inProgressOption - Option about progress is specified. this must be set one of the following values. kEdsProgressOption_Done When processing is completed,a callback function is called only at once. kEdsProgressOption_Periodically A callback function is performed periodically. inContext - Specifies an application-defined value to be sent to the callback function pointed to by CallBack parameter.

Without modification, stream objects cannot be worked with as images. Thus, when extracting images from image files, you must use this API to create image objects. The image object created this way can be used to get image information (such as the height and width, number of color components, and resolution), thumbnail image data, and the image data itself. Parameters: In: inStreamRef - The reference of the stream. Out: outImageRef - The reference of the image. Returns: Returns EDS_ERR_OK if successful.

Returns uncompressed results for JPEGs and processed results in the designated pixel order (RGB, Top-down BGR, and so on) for RAW images. Additionally, by designating the input/output rectangle, it is possible to get reduced, enlarged, or partial images. However, because images corresponding to the designated output rectangle are always returned by the SDK, the SDK does not take the aspect ratio into account. To maintain the aspect ratio, you must keep the aspect ratio in mind when designating the rectangle. Parameters: In: inImageRef : The reference of image object inImageSource : Specfies kind of image - thumbnail, preview, fullview inImageType : Specifies image type ID number inSrcRect : Rectangle of the source image inDstSize : Designate the rectangle size for output. Out: outStreamRef : The reference of memory stream Returns: Returns EDS_ERR_OK if successful.

Creating the cache increases the processing speed, starting from the second time. Parameters: In: inImageRef - The reference of the image. inUseCache - Whether cache image data , If TRUE, cache image. If FALSE, the cached image data will released. Out: none Returns: Returns EDS_ERR_OK if successful.

Live view can be started by using the property ID:kEdsPropertyID_Evf_OutputDevice and data:EdsOutputDevice_PC to call EdsSetPropertyData. In addition to image data, information such as zoom, focus position, and histogram data is included in the image data set. Image data is saved in a stream maintained by EdsEvfImageRef. EdsGetPropertyData can be used to get information such as the zoom, focus position, etc. Although the information of the zoom and focus position can be obtained from EdsEvfImageRef, settings are applied to EdsCameraRef. Parameters: In: inCameraRef - The Camera reference. In: inEvfImageRef - The EVFData reference.
