How can an emoji be displayed? - PhilOfPerth - 04-21-2024

I would like to use an "emoji" (or similar) in my programme. Is there a (simple) way to do this? I don't see any appropriate symbols in the ASCII code.

You'll need to either do this with an image (_LOADIMAGE then _PUTIMAGE) or find a font that contains the images you're looking for.

Fonts can contain small images, often referred to as dingbats: https://www.dafont.com/mtheme.php?id=7

Thanks Terry.
I found what I wanted in Wingding (a font I never expected to use).
I found I can change fonts mid-stream, but the new font seems to place the print position as 1,1.
I can fix this by using Locate r,c but wondered if there's a setting when using the new font that bypasses this?
Also, I only want to use one character, then revert to my old font. Is there a shorter way than re-re-setting my font?

Code: (Select All)

Sub SafeLoadFont (font#)

    'Safely loads a font without destroying our current print location and making it revert to the top left corner.



    down = CsrLin: right = Pos(0)

    down = (down - 1) * _FontHeight

    If _FontWidth <> 0 Then 'weed start with a monospace font

        right = (right - 1) * _PrintWidth(" ") 'convert the monospace LOC to a graphic X coordinate

    End If

    _Font font#

    If _FontWidth <> 0 Then 'we swapped to a monospace font

        right = (right / _PrintWidth(" ")) + 1 'convert the graphic X coordinate back to a monospace LOC column

    End If

    down = (down / _FontHeight) + 1

    If right < 1 Then right = 1

    Locate down, right

End Sub

Instead of using _FONT to swap to the new font, use _SafeLoadFont instead. It's been a standard part of my extended toolbox of routines which I make use of for years now. Smile

For a quick print of a single character, like your emoji, just use the above with a little helper code:

SUB PrintSmiley
f& = _FONT 'get the current font so we can restore it.
SafeLoadFont <whatever the handle is for the wingding font you loaded earlier in your code>
Print Chr$(<whatever the value is for the character>);
SafeLoadFont f& 'restore the current font back.
END SUB

Thanks Steve.
I'll have a fiddle with that;
I don't really see much difference between that and just re-declaring my original font though.
Maybe the difference will become more obvious when I use it.

Since we display unicode we should be able to display emojis? I know that we should be able to do this in terminals that support UTF-8. Just print out the unicode code point code to the terminal and it will display the emoji configured in the system? Or is this wrong?

Is it that when using a graphics screen mode the emojis will not render properly?

TBH I haven't tried to render an emoji in terminal yet. (the terminal must support it - windows terminal, xterm, mac terminal, etc. all do).

Yeah. I too am not sure if printing emojis to the terminal will work with QB64's PRINT. I'll need to play with that.

However, printing to a graphics screen with _UPRINTSTRING should work. Note that we do not have color font support yet. So, the below will print in monochrome (you can pick a single color of your choice).

Code: (Select All)

SCREEN_NEWIMAGE(800, 600, 32)



DIM fnt AS LONG: fnt = _LOADFONT("Seguiemj.ttf", 22)



COLOR _RGB32(255, 0, 255)



_UPRINTSTRING (100, 100), MKL$(&H1F638&), , 32, fnt

Update:

Added sample font with emojis.
