I spent a bit of time today updating my CLI program for converting SCR files to GIF, PNG, or JPG files.

The source code is available on github: https://github.com/mrcook/scrconv

Featues:

* PNG, JPG, and GIF output formats
* auto format output: PNG by default, or an animated GIF when a screen contains flashing colours
* with or without the border
* set a customer border colour
* scaled images: 320x240 (default), 640x480, 960x720, 1280x960
* experimental auto-border colour, based on colours in the image

This is a terminal program written in the Go language, so you'll need to have Go installed to be able to compile it. This though is very simple:

Code: Select all

go install github.com/mrcook/scrconv/cmd/scrconv@latest

I haven't tested it on Windows, but I see no reason why it shouldn't work. I guess you just need to use "go.exe install" instead.

Notes on the auto-border colour feature:

The detection is pretty simple: it just counts the total number of PAPER and INK colours and chooses the most common one. I experimented with 30 or so screens and the result is that most will still have a black border. Of those that don't these are the more interesting ones: Lords of Midnight, Carrier Command, Monty on the Run. The only one I tried that was not so great is Knight Lore.

I guess not many people will find a use for this but if you do, well, here it is!

Nice idea!

But why consider the whole screen for the counting and not only the border "squares" (first and last column and first and last row)?

On macos this command is used on the terminal:

Code: Select all

go build ./cmd/scrconv

My assumption is that it would be the same on Windows, but using go.exe. I don't however have a windows machine to test that.

Sorry lfaria but I don't understand the question.

They mean only check the colours in a 1 character width (could add a tweak for wider I suppose) around the border (so row 0, 23 and columns 0, 31) and not the colours in the middle of the screen.

EDIT: Although a contrasting border is good too really so I don't think there's a best way to do it.

Ah right, gotcha. Certainly worth a look at!

I've already figured it out. 2738716 bytes is too much

My laptop hard drive has 549,755,813,888 bytes, so I don't care.
