'Create map image' doesn't seem to work on larger map files, created image file doesn't have an extension by default

[MMMiracles]

Edit (Rockdtben):

-To fix this look into performance issues on Create map image.
-Add performance metrics and error logging to Create Map Image. Possibly an output window to display all errors. There are a lot of errors that are silently reported to the Console, but not to the user. We should add visibility to that for "Issue" reporting.

End Edit (Rockdtben)

Trying to use the 'Create map image' option on larger dmm files, such as stations or away missions doesn't result in anything. Smaller dmm files like ruins do not have this issue.

The generated image doesn't have an extension by default for some reason, need to add an extension afterwards for it to work.

Running on Windows 10 Home Edition, 64x, Java 8 Update 144.

@MMMiracles Which big map doesn't work for you? I can check that one first.

[MMMiracles]

Boxstation is an example of a map that wouldn't generate an image.

[Rockdtben]

I am able to repro. Thanks. I got "test" with no extension when trying to generate an image.

[Rockdtben]

Changing the file extension gave me an image.

renamed test -> test.png

Does that work for you and does the image look good? If so then I'll fix the extension issue.

I guess I wasn't fully clear on the extension part, I was trying to say the file worked fine when I added an extension myself.

@MMMiracles For larger stations does adding the extension work?

[MMMiracles]

I don't get a file at all when trying to generate larger stations.

@MMMiracles Could you check your "Documents" folder. Or whatever your default directory is that FastDMM is pointing to

1.Save Image to Desktop
2. Attempt to save again and notice that file location selector is pointing to Documents and not Desktop.

@MMMiracles Are you on 32 or 64 bit Java?

@MMMiracles Also could you download the latest version and try again?
