Slowness in MagickImage Object Creation

[MuteebAhmad148]

Hi!
I'm trying to create a label Image and place it on top of another MagickImage.

But the issue is MagickImage object creation for label image is taking a long time (around 5 mints). Also, I'm using a long caption here which is around 2000 characters . It's works fine (still not that fast) with shorter captions.

Thanks

Is it possible to provide a code sample that can be used to reproduce this issue?

Hi @dlemstra
Thanks for your response.
I have attached the sample code file. You can use the attached background image to test the issue.
MagickImage Object creation is Line Number 36 is taking a long time to execute.

We made some improvements to the caption coder of ImageMagick. And it might help if you use this new feature:

questionTextSettings.SetDefines(new CaptionReadDefines
{
    StartFontPointsize = 7, // You might need to tweak this value.
});

You should see an improvement but we will check if we can make some more improvements in the future.

Hi
Thanks for sharing this update.
I have tested it with latest version 8.4.0. It is still taking around 1 minute to create MagickImage object for 1000 character's caption, which is still a lot of time.

Your best Option for right now is probably to convert it to a Bitmap, and using System.Graphics.DrawString to create the Caption. the conversion will take less than 50 milliseconds, I know that's not Ideal but it will solve the problem

This is happening because the part that tries to figure out how to write the text without the specified boundaries is not that fast. But I haven't had time yet to see if we could speed up that part.
