生成了HUD.dll后,C#如何调用

你好，我在win7 x64 上生成HUD解决方案，得到了HUD.dll后，怎么在c#的项目(比如console应用)中使用，我添加HUD.dll引用时提示不是有效的程序集或COM组件

high dpi support

target project to .net framework 4.6 and add the following code to app.config:

  <appSettings>
    <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />
  </appSettings>

and add a manifest file app.manifest, the settings should be generated automatically, enable the following section:

  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
    </windowsSettings>
  </application>

and rebuild.
the ui will support high dpi.

Parameter is not valid

invoke_dll.invoke_heif_to_jpg works great on most heic files, however a few files return exception "Parameter is not valid".

Nokia 官網圖片不能顥示

測試用文件: https://github.com/nokiatech/heif/blob/gh-pages/content/images/cheers_1440x960.heic

拿到app去, 只顥示無法打開文件，並沒有進一步報錯。

謝謝

Cannot open .heic files on Windows 10 Pro 1703 64 bit

It seems like under Windows 10 1703 (creators update) 64 bit the utility program cannot open any .heic files, even if Visual C++ 2015 redistributable is installed. Suggested testing/keeping compatibility on the following Windows Platforms (see below).

Using on an ASP.NET site > image invalid format

I used your libraries to convert HEIF to JPEG. And on a windows machine (Console-Application) it works like a charm.

Now I try to do the same thing on an ASP.NET site (Web-API) to convert incoming images.

I don't get an error message from the HUD.dll while converting the file. It seems like it works, because I successfully get a ByteArray as a result form the "invoke_heif2jpg" method.

But when I try to save this result-byte-array as a jpeg, the image is corrupted. The format is wrong.
I get a "System.ArgumentException: Invalid parameter" exception when I call the following code:

var image = Image.FromStream(new MemoryStream(jpegByteArray));

I have this problem when I call the HUD.dll directly form withing the API-Method and (like your ONLINE-code) when I start a separate process.

What can be wrong? Thanks

部分转换失败

非常好用，感谢。
但部分转换失败，貌似是因为这些图片在手机上被编辑过的原因（只用苹果自带图片编辑或snapspeed），能否研究一下。
再一个能否保存上一次批量转换的设置，输出路径和质量

Issue when converting images from URI

I have an issue where i get an error message after converting images from URI "this is not a valid bitmap file, or its format is not currently supported" when i try and open the jpg after it has been converted. I do not get any error messages from the invoke_dll during the conversion process.
By default the read_heif method does not accept a URI as the filename. I have had to add the following code to that method to read the URI:

                HttpWebRequest request = null;
                HttpWebResponse response = null;
                request = (HttpWebRequest)WebRequest.Create(filename);
                response = (HttpWebResponse)request.GetResponse();
                if (request.HaveResponse)
                {
                    if (response.StatusCode == HttpStatusCode.OK)
                    {
                        Stream receiveStream = response.GetResponseStream();

                        using (BinaryReader br = new BinaryReader(receiveStream))
                        {
                            byte_array = br.ReadBytes((int)response.ContentLength);
                            br.Close();
                        }
                    }
                }

i then sucesfully get a byte[] and can make a call to invoke_heif2jpg() and i get a converted jpg back. But when i try and open that jpg i get the error mentioned.

Have you seen this error at all or know of any way to correct this error?

Thank you for the great utility!

Anybody has any idea?

I just downloaded your utility from your dropbox link, i am trying to use the english version on Windows 7. When i open the file i get the error:
"Unable to open this file."
Please see example files here: https://wetransfer.com/downloads/85ba7bab2c08ccab582bc0c15812a77b20170918174707/9ac949e960baa80db1c5952fc53cfff820170918174707/2ef3df
