Hello Sir,

I had tried to build this code on my machine with visual studio 2015 on windows 10 operating system. I got an error "The core component is missing. HEIF UTILITY cannot start".

近期 Google 相册已经支持了 HEIF 格式的备份，此工具可以将 JPEG 图片转化为 HEIF 格式吗。为硬件、网盘同时节省空间。

其实我们要的是把相机RAW格式或者JPG转换转成heic格式。

What is that?

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

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

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.

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).

Hello,

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

Convert JPEG images to Apple HEIF images please!

The UI blurs on my 150% dpi monitor.

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!

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

I followed the instruction here https://liuziangexit.com/HEIF-Utility/Help/No14.html.

Here is the ouput:

$ sha1sum HEIF-Utility-Thumbnail-Provider.dll
3c03912eaf49dd76ed2f66d27ddd48d4a8344609  HEIF-Utility-Thumbnail-Provider.dll

Anybody has any idea?

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

拿到app去, 只顥示無法打開文件，並沒有進一步報錯。

謝謝
