Font size calculating

[vendelieu]

Could you add the adaptability of the size of the font. Calculating the size of the font depending on the length of the text. This will allow small texts to see more clearly, bigger.

Try This First Declare the Text In a Variable

$imgtxt = 'Some Text';

$imy = imagesy($im);

$txtchars = strlen($imgtxt);

$customfontsize = '15';

$fontsize = ($imy - $txtchars) / 5;
$fontsize = $fontsize + $customfontsize;

And Then

$box->setFontSize($fontsize);
$box->draw($imgtxt);

@CFlanc your snippet doesn't work :(

@Lukasss93 does you text size change to big when the string is small if yes then try playing around with the initial font size and other values and see if you get the desired results

@CFlanc

does you text size change to big when the string is small

Nope :(

[CFlanc]

Then something must be wrong with the code @Lukasss93 Ok maybe because you are creating image from color You cant use imagey command

You should enter the actual width

[Lukasss93]

This is my code: //config $text='asd sad asdsa asd asdasd asda asdadasdd dasdasdasd aasdasd'; $initialfontsize=50;

//canvas $im = imagecreatetruecolor(512, 512);

//set transparent background $background=imagecolorallocate($im, 123, 123, 123); $background=imagecolortransparent($im, $background); imagefill($im, 0, 0, $background);

//auto size font? $imy = imagesy($im); $txtchars = strlen($text); $fontsize = ($imy - $txtchars) / 5; $fontsize = $fontsize + $initialfontsize;

//text $box = new Box($im); $box->setFontFace(FCPATH.'assets/fonts/arial.ttf'); $box->setLineHeight(1); $box->setFontColor(new Color(0, 0, 0)); $box->setBox(0, 0, 512, 512); $box->setTextAlign('center', 'center'); $box->setStrokeColor(new Color(255, 255, 255)); $box->setStrokeSize(3); $box->setFontSize($fontsize); $box->draw($text);

//output + destroy header("Content-type: image/png;"); imagepng($im, null, 9, PNG_ALL_FILTERS); imagedestroy($im);
