C#中的WIA取景器 [英] WIA viewfinder in c#

问题描述

我正在尝试用c#编写程序来绑定佳能s3is数码相机.

当我连接相机时，似乎进入一种睡眠模式或连接模式，镜头缩回，并且取景器中没有图像，但我可以在资源管理器中看到相机.

我可以使用WIA进行拍照，打开相机，拍照，然后返回睡眠模式"，所以我想这意味着它可以兼容wia.

现在，我需要在程序中使用实时取景器，但是我似乎找不到有关如何执行此操作的任何信息.

我尝试使用IWIAVideo的CreateVideoByWiaDevID，但它给出了异常HRESULT:0x80210015.显然这意味着设备不兼容或缺少，这很奇怪，因为我可以用它来拍照...

我确实可以使用canon SDK，但是我只是出于爱好而编程，所以我对C(SDK语言使用)，指针，标头，回调和使用SDK似乎需要的所有其他东西都不熟悉.

i''m trying to write a program in c# for tethering a canon s3is digital camera.

When i connect the camera it seems to go into a kind of sleep mode or connection mode, the lens is retracted and no image in the viewfinder but i can see the camera in explorer.

I''m able to make it take pictures using WIA , the camera turns on , take a picture and goes back to ''sleep mode'' so i guess that would mean it''s wia compatible.

Now i need to have the live viewfinder work in the program but i can''t seem to find any info on how to do that.

i tried using CreateVideoByWiaDevID from IWIAVideo but it gives an exception HRESULT: 0x80210015. Apparently it means the device is not compatible or abscent which is weird cause i can take pictures with it...

I do have access to the canon SDK but i do programming for a hobby and i''m not familiar with C (the sdk language uses), pointers , headers , callback and all the other things that seems to be necessary to use the SDK

any help will be apreciated

推荐答案

我为佳能SDK编写了一个C#包装器，这是Code Project上的一篇文章.只需搜索佳能.它可能已经过时了很多，但是如果您想更新它，或者只是看看它是否有效，这可能是前进的方向.假设它是相同的SDK.

当我尝试使用WIA而不是该SDK时，我所能做的就是拍照，不使用取景器等.SDK允许我设置所有相机设置，缩放，预览等.

I wrote a C# wrapper for the Canon SDK, it''s an article here on Code Project. Just search for Canon. It''s probably quite a bit out of date, but it could be the way forward if you wanted to update it, or just see if it works. That''s assuming it''s the same SDK.

When I tried using WIA instead of that SDK, all I could do was take pictures, no viewfinder, etc. The SDK let me set all camera settings, zoom, preview, etc.
