How to get a text properly and accurately?

[mastah]

I tried TesseractGetText but it's just to unreliable and it makes too many mistakes.
For example I want to get text 'x' at some area for multiple fonts.

So I tried making my own bitmaps:

I tried loading the font..

But then I got this error: Exception in Script: Runtime error: "Error while reading stream: Wrong image format"

GetTextAt I don't understand either, could someone explain the parameters?

Is it possible to get a text in an area which is for example 'hello SRL' accurately?

Show us a image of the text you want to read?

Thanks alot for your help!

Tesseract works perfect for me.. It's all how you process the image.

Wrong image format? Well then, in what format are you attempting to have Simba read the text? For most (if not all) intents and purposes, Simba will only accept files in bitmap (.bmp) format.

Showing us the portion of your code which you think causes the issue is a good thing to do when asking for help!

Yes in this case it works but sometimes it doesn't I tried, I want something more secure. You even now see a space between the output.

Great thanks!

I'm saving it as a .bmp I created only the letter '1' and saved is as 1.bmp
Then I tried searching for it.

This is the code:


{$I SRL-6/SRL.simba}
{$I SPS/lib/SPS-RS3.Simba}

var
text: string;

procedure declareVariables();
begin
LoadFont('Chars', false); //->shadow???
end;

begin
clearDebug();
setupSRL();
declarePlayers();
declareVariables();
text:= GetTextAt(300, 316, 0, 0, 0, 3111603, 0, 1, 'Chars');
WriteLn(text);

end.
