Create Font

Hello everybody,

In the SDK, there is this example : 

fontReg.Register("pkg:/fonts/LCDMono.ttf")
font = fontReg.Get("LCDMono",36,50,false) ' 36pt, 50 is normal weight, no italics


I suppose the second figure represents the fact that the font is bold or not. Am i wrong? If no, why a value, and not a boolean like italics? How do you know which value to chose?

Thank you.

Denis


EDIT:
I managed to get text shown on a roScreen with default settings, but when i create my font nothing appears. Is there something i am missing? I created a "fonts" folder and copied the ttf files from my windows in it.

my_font = CreateObject("roFontRegistry")
my_font.Register("pkg:/fonts/calibri.ttf")
my_font.Get("calibri", 14, 50, false)
bitmap.DrawRect(x, y, 300, 50, &h00000000)
bitmap.DrawText(Final_Array[i][j], x, y, &hFFFFFFFF, my_font)
screen.DrawObject(0, 0, bitmap)
screen.Finish()


Thank you.

    Well it looks like roScreen doesn't use the roFontRegistry even if it uses the DrawText function from ifDraw2D, so i changed for a roImageCanvas, and it works fine so i'll go on with canvas.

    Nobody knows how to chose the second figure when creating the font?
    I tried with 1, 50 and 100, and i can't see any difference.
    Thank you.

    I think it depends on the font. Some fonts have multiple different weights. If the font you're using does, then the number you provide determines which weight to use. If your font only has one weight for bold, then any value you supply will return the same.

    Ok, but how can I know if my font does or not please? I have opened the ttf files of my font, which is times for the moment, but i don't see anything concerning the weight, only examples of sizes.

    I'm not sure. I imagine, if you're licensing a font for use in your channel, the documentation for that font should tell you. Chances are, if you're not seeing a difference, then either the font you're using doesn't have different weights, or it's not actually implemented in the firmware.. For what it's worth, the roScreen version of GetFont() only accepts a True/False for the boldness parameter.

    Thank you.


    In my code I do something like this:

    frg = CreateObject("roFontRegistry")
    frg.Register("pkg:/fonts/myfont.ttf")
    fonts = frg.GetFamilies()
    font = frg.GetFont(fonts[0], 32, false, false)
    bmp.DrawText("My Text", 0, 0, &h000000FF, font)


    Hope that helps. Note that this pulls the first font variation. Some fonts will have multiple variations (i.e. condensed). It looks like the mistake in your code is that you are trying to use an roFontRegistry object in the place of an roFont object in your DrawText function.

    Well I corrected and I can now chose my font and its size, though I still cannot find how to use boldness, but that will be ok.
    Thanks to both of you 😄
