[Quote=引用 2 楼 dext 的回复:]
Qt Library 分为 两种,一种是 纯源代码 你必须下载编译器,配置,然后 编译,最后 才能使用 Qt 库开发
另一种 是 编译后的 源代码。
[/Quote]
挑个刺,甚么是 "编译后的 原代码" 啊? 应该说的是头文件与库文件吧。

Qt SDK 你只要安装了,应该就可以直接开发程序了。(如果你没有其它的 C++ 编译器,如果有,可能要设置)

另一种 是 编译后的 源代码。
首先 你要下载 编译器,如果再下载 纯源代码 版的,编译后 就是 另一种的 Qt Library 包括 Qt Assistant, Qt Designer.....
如果 再下载了 Qt Creator IDE 的源代码 编译后 就是 Qt 的 SDK 了

; {----------------------------------------------------------------------------- Function : EdsGetImage Description: Gets designated image data from an image file, in the form of a designated rectangle. 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. In other cases, see ED
SDK

; {----------------------------------------------------------------------------- Function : EdsSaveImage Description: Saves as a designated image type after RAW processing. When saving with JPEG compression, the JPEG quality setting applies with respect to EdsOptionRef. Parameters: In: inImageRef : The reference of image inImageType : Specifies image format ID number inSaveOption : Specifies save option Out: outStreamRef : The reference of file stream Returns: Returns EDS_ERR_OK if successful. In other cases, see ED

; {----------------------------------------------------------------------------- Function : EdsCacheImage Description: Switches a setting on and off for creation of an image cache in the
SDK
for a designated image object during extraction (processing) of the image data. 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. In other cases, see ED

Parameters: In: inImageRef - The reference of the image. Out: none Returns: Returns EDS_ERR_OK if successful. In other cases, see ED
SDK

Parameters: In: inStreamRef - The stream reference which opened to get EVF JPEG image. Out: outEvfImageRef - The EVFData reference. Returns: Any of the
sdk
errors. -----------------------------------------------------------------------------} function EdsCreateEvfImageRef ( inStreamRef : EdsStreamRef; var outEvfImageRef : EdsEvfImageRef ) : EdsError; stdcall; external ed
sdk
; {----------------------------------------------------------------------------- Function: EdsDownloadEvfImage Description: Downloads the live view image data set for a camera currently in live view mode. 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. Returns: Any of the
sdk
errors. -----------------------------------------------------------------------------} function EdsDownloadEvfImage ( inCameraRef : EdsCameraRef; inEvfImageRef : EdsEvfImageRef) : EdsError; stdcall; external ed

Parameters: In: inCameraAddedHandler - Pointer to a callback function called when a camera is connected physically inContext - Specifies an application-defined value to be sent to the callback function pointed to by CallBack parameter. Out: None Returns: Returns EDS_ERR_OK if successful. In other cases, see ED

; {----------------------------------------------------------------------------- Function : EdsSetPropertyEventHandler EdsSetObjectEventHandler EdsSetCamerStateEventHandler Description: This function registers the callback function called when an event occurs to the camera. EdsSetPropertyEventHandler Registers a callback function for receiving status change notification events for property states on a camera. EdsSetObjectEventHandler Registers a callback function for receiving status change notification events for objects on a remote camera. Here, object means volumes representing memory cards, files and directories, and shot images stored in memory, in particular. EdsSetCamerStateEventHandler Registers a callback function for receiving status change notification events for camera objects. Parameters: In: inCameraRef - The reference of the camera. inEvent - Event ID number ( PropertyEvent, ObjectEvent, StateEvent ) inEventHandler - Pointer to a callback function called when an event occurs to the camera. inContext - Specifies an application-defined value to be sent to the callback function pointed to by CallBack parameter. Out: None Returns: Returns EDS_ERR_OK if successful. In other cases, see ED
