This function retrieves the theoretical width and height (in pixels) of a certain piece of text, if it were to be drawn using dxDrawText.

NOTE: This function already takes the client's screen resolution into account.

Syntax

float, float dxGetTextSize ( string text [, float width = 0, float scaleXY = 1.0 [, float scaleY = 1.0 ], mixed font = "default", bool wordBreak = false, bool colorCoded = false] )

OOP Syntax Help! I don't understand this!

Note: This syntax requires you to ignore the font argument above
Method: font:getSize(...)


Required Arguments

  • text: A string representing the text for which you wish to retrieve with width for.

Optional Arguments

NOTE: When using optional arguments, you might need to supply all arguments before the one you wish to use. For more information on optional arguments, see optional arguments.

  • width: The width of the text. Use with wordBreak = true.
  • scaleX: The scale of the text. Scale can also be inputted as a Vector2.
  • scaleY: The scale of the text.
  • font: Either a custom DX font element or the name of a built-in dx font:
    • "default": Tahoma
    • "default-bold": Tahoma Bold
    • "clear": Verdana
    • "arial": Arial
    • "sans": Microsoft Sans Serif
    • "pricedown": Pricedown (GTA's theme text)
    • "bankgothic": Bank Gothic Medium
    • "diploma": Diploma Regular
    • "beckett": Beckett Regular
    • "unifont": Unifont
  • wordBreak: If set to true, the text will wrap to a new line whenever it reaches the right side of the bounding box. If false, the text will always be completely on one line.
  • colorCoded: Should we exclude color codes from the width? False will include the hex in the length.

Returns

Returns two floats representing the width and height of the text in pixels.

Example

This example draws a text with black background at the bottom right corner of the screen. 

local screenWidth, screenHeight = guiGetScreenSize()

local message = "Incredibly huuuuuuuge message"
local messageOffset = 32
local messagePadding = 16
local messageWidth = 256

function renderMessage()
    local textWidth, textHeight = dxGetTextSize(message, messageWidth, 2, "default", true)
    local x = screenWidth - textWidth - messageOffset
    local y = screenHeight - textHeight - messageOffset
    dxDrawRectangle(x - messagePadding, y - messagePadding, textWidth + messagePadding * 2, textHeight + messagePadding * 2, 0x80000000) -- draw background
    dxDrawText(message, x, y, x + textWidth, y + textHeight, 0xFFFFFFFF, 2, "default", "left", "top", false, true)
end
addEventHandler("onClientRender", root, renderMessage)
