MagickImage cannot detect correct image format with ReadAsync
#1174
Comments
Thanks for reporting this I just pushed a fix for this issue that will be resolved in the next release. |
I hope this fix can be released some time this week, or else I will miss it for ImageGlass 9.0 beta 1 🕊 |
Hi @dlemstra, The bug still persists when using using var imgColl = new MagickImageCollection();
// ❌ CANNOT detect format
settings.Format = MagickFormat.Ico;
await imgColl.ReadAsync(filename, settings, cancelToken);
// ✅ CAN detect format
await imgColl.ReadAsync(filename, settings, cancelToken);
// ✅ CAN detect format
imgColl.Read(filename, settings); I checked the MagickImageCollection source code a bit, and found this: Magick.NET/src/Magick.NET/Netstandard21/MagickImageCollection.cs Lines 292 to 301 in 8a4f9de
Magick.NET/src/Magick.NET/Netstandard21/MagickImageCollection.cs Lines 582 to 601 in 8a4f9de

Seems that I only fixed this in the |
Magick.NET version
11.1.0 - Magick.NET-Q16-OpenMP-x64
Environment (Operating system, version and so on)
Windows 10 21H2
Description
<MagickImage>.ReadAsync()
and<MagickImageCollection>.ReadAsync()
function.ReadAsync
because it supportsCancellationToken
, and it's convenient to do some quick check before loading entire image file which is time-consuming.Steps to Reproduce
Code produces error:
Code without error:
Solution 1: Directly pass filename to constructor
Solution 2: Tell what the format is
