Some kind of engine for...

[12p]

Creating images from simple strings or another arguments.

E.g: CAPTCHAS. Those uses texts on images, right? IDK how do those work, but someway it works with MANY random images. If this suggestion is accepted, it may help to reduce good download space.

That would be really useful. Don't know when GTA San Andreas will be open-source.

what? you can make a captcha pretty easily with dx functions.

[diegofkda]

For captcha you can use Custom Fonts or DirectX functions as well.

[12p]

It was just kinda an example. There must be something else that you can use the functions I suggest for.

function dxCreateCaptcha(length) 
   local c = createElement("dxCaptcha") 
   local alph = {"a","b", "c", "d", "e", "f", "g", "h", "i",  "insertmore"} 
   local captch = "" 
   for i=0, length do 
     if math.random(2)==2 then 
       captch = captch..alpha[math.random(#alph)] 
     else 
       captch = captch..math.random(0,9) 
     end 
   end 
   setElementData(c, "captcha", captch) 
   return c 
end 
function dxDrawCaptcha(captcha) 
     if not isElement(captcha) 
     -- bunch of dxDrawText calls 
end 
end 
  

sorry about the create element thing, i was just kinda bored

This is very easy to make, theres no need for a built-in solution. Simply have a library of small images of the numbers 0-9 and letters a-z client-side (client/images/captcha/a.png for example). Then, when a captcha code is needed, request a random string from the server. When the string is recieved, split it into a table, and then for each character in the string, draw the proper image. For example:

  
--The width of a captcha image will remain the same at all times 
local characterWidth, characterHeight = 48, 48 --These are static values, all captcha images should be the same size. 
local captchaCode = string.split(strCaptcha) --Where 'strCaptcha' is what is recieved from the server. 
  
local x = 0 --This should be whatever the actual gui element's x position is 
local y = 0 --Same for this 
--Draw the individual images 
for _, character in ipairs(captchaCode) do 
    dxDrawImage(x, y, characterWidth, characterHeight, "client/images/captcha/"..character..".png") 
    x = x + characterWidth 
end

not images, but rotated texts with different fonts

[Aibo]

this is not a scripting section.

and i doubt Benxamix2 knows himself what is this suggestion for ("some engine" for "some functions"? "Creating images from simple strings or another arguments" - what?)

[AGENT_STEELMEAT]

the images would be of rotated texts with different fonts - this is how its done in the actual captcha system commonly found

[qaisjp]

why create an image for numbers 0-9 and letters a-z when you can jst use fonts and randomly generated angles?

[AGENT_STEELMEAT]

You can't rotate DX texts, unless you get fancy and use dxDrawLine on special character elements.

[qaisjp]

You can't rotate DX texts

wat.

[AGENT_STEELMEAT]

bool dxDrawText ( string text, int left, int top [, int right=left, int bottom=top, int color=white,  
                  float scale=1, mixed font="default", string alignX="left", string alignY="top", 
                  bool clip=false, bool wordBreak=false, bool postGUI ]  

I see no rotation args.

[qaisjp]

Dear MTA, please add rotation args to dxDrawText. Thanks.

[karlis]

create render target and rotate it...

problem much?
