PDF manual version 3.3

[Dalede]

I think that Apple is the owner of the problem

Actually Unix is the owner of the problem. It started the case sensitivity thing soon after lower case was added to the ASCII set. By late 1969 the damage was done

[Mr. Kibernetik]

OS X is a direct descendant of Unix, and its file system is not case sensitive.

[Dalede]

OS X is a direct descendant of Unix, and its file system is not case sensitive.

Actually it is. If you use the Unix commands that are inside OS X you will find that the disk is actually storing the data case sensitive but the user interface masks this so it looks like it is not case sensitive. This is also true of Windows although for Windows you will need to download a Unix command set, but OS X has one built-in.

That's what I should do if I noticed this before...

[Dutchman]

I am now preparing the new manual version 3.4.
In the modifications I read

GRAPHICS CLEAR now clears the screen to its transparent state.

I suppose that not all graphics are cleared, but only the graphics in the actual graphics ('sprites') layer.
Is that correct?

[Mr. Kibernetik]

GRAPHICS CLEAR clears only current graphics layer. It can be main graphics window or a sprite.

[Dutchman]

I used already transparency in MercatorWorld e.g. for the city-info panel.
What is then the new feature?

[Mr. Kibernetik]

Now it works also for main window, to be consistent for all graphics layers, not only sprites.

[Dutchman]

But there is no 'lower' layer which could be seen through the transparency.
How can it be used

[Mr. Kibernetik]

It can be used to create images with transparency.
For example you can scan part of main window to a sprite, or you can save part of main window to a file. And now you can have transparency in all these situations. Previously it was not possible.

Please note that now you can erase images, not only draw them - both in sprites and in main graphics window.
So, [GRAPHICS CLEAR] now clears completely, and [GRAPHICS CLEAR r,g,b] clears to desired color.
