Difficulty getting font dimensions with powershell

Posted: 01 Jun 2024 03:37

Hi,

I've made these simple batch functions, that obtain font size, font width and font height using a powershell/C# hybrid oneliner

Using this command, you can set the font size to every size from 1 to 40
And then print out the font dimensions

Code: Select all

for /l %a in (1,1,40) do (SetFontSize %a & GetFontdimensions.bat )
However I am getting small discrepancies in the values and I cannot find the bug ?

Here is the result and what it should have been

Code: Select all

FontSize: 1 FontWidth: 1 FontHeight: 1
FontSize: 2 FontWidth: 1 FontHeight: 2
FontSize: 3 FontWidth: 2 FontHeight: 3
FontSize: 4 FontWidth: 2 FontHeight: 4
FontSize: 5 FontWidth: 2 FontHeight: 5
FontSize: 6 FontWidth: 3 FontHeight: 6
FontSize: 7 FontWidth: 3 FontHeight: 7 (FontHeight should have been 6)
FontSize: 8 FontWidth: 4 FontHeight: 8
FontSize: 9 FontWidth: 4 FontHeight: 9
FontSize: 10 FontWidth: 5 FontHeight: 10
FontSize: 11 FontWidth: 6 FontHeight: 11 (FontWidth should have been 5)
FontSize: 12 FontWidth: 6 FontHeight: 12
FontSize: 13 FontWidth: 6 FontHeight: 13
FontSize: 14 FontWidth: 6 FontHeight: 14 (FontWidth should have been 6)
FontSize: 15 FontWidth: 7 FontHeight: 15
FontSize: 16 FontWidth: 7 FontHeight: 16 (FontWidth should have been 7)
FontSize: 17 FontWidth: 8 FontHeight: 17
FontSize: 18 FontWidth: 9 FontHeight: 18 (FontWidth should have been 8)
FontSize: 19 FontWidth: 9 FontHeight: 19
FontSize: 20 FontWidth: 10 FontHeight: 20 (FontWidth should have been 9)
FontSize: 21 FontWidth: 10 FontHeight: 21 (FontHeight should have been 22)
FontSize: 22 FontWidth: 10 FontHeight: 22
FontSize: 23 FontWidth: 11 FontHeight: 23
FontSize: 24 FontWidth: 11 FontHeight: 24
FontSize: 25 FontWidth: 12 FontHeight: 25
FontSize: 26 FontWidth: 12 FontHeight: 26
FontSize: 27 FontWidth: 13 FontHeight: 27
FontSize: 28 FontWidth: 13 FontHeight: 28
FontSize: 29 FontWidth: 14 FontHeight: 29
FontSize: 30 FontWidth: 14 FontHeight: 30
FontSize: 31 FontWidth: 14 FontHeight: 31 (FontWidth should have been 15)
FontSize: 32 FontWidth: 15 FontHeight: 32
FontSize: 33 FontWidth: 15 FontHeight: 33
FontSize: 34 FontWidth: 16 FontHeight: 34
FontSize: 35 FontWidth: 17 FontHeight: 35 (FontWidth should have been 16)
FontSize: 36 FontWidth: 17 FontHeight: 36
FontSize: 37 FontWidth: 18 FontHeight: 37 (FontWidth should have been 17)
FontSize: 38 FontWidth: 18 FontHeight: 38
FontSize: 39 FontWidth: 18 FontHeight: 39
