Hey list! :)
I've got a problem trying to calculate a string width using an X font
with some Y font size to use in an svg-to-pdf conversion.
This is what I try to do:
1. Create a dummy image.
2. Set the text there using font X and the font size Y (it seems that
when I create the image it renders it at 72dpi so I need to reduce it at
300dpi)
I'm not sure what the imagettftext() function returns, are those values
measured in pixels ? I read in some page that the proportion to reduce
the image at 300dpi is reduce the size to 24% of its original size.
http://www.printingforless.com/resolution.html
That's the code:
***
// Create dummy image.
$rsc_image = imagecreate( 1, 1 );
// Set image.
$arr_ftx = imagettftext( $rsc_image, $int_font_size, 0, 0, 0, -1,
"./fonts/{$str_font_file}", $str_variable_value );
// Destroy dummy image.
imagedestroy( $rsc_image );
// Set structure of widths.
// TODO: Magik numbers.
$arr_variable_pixels[$str_variable_index] = ( ( $arr_ftx[2] * 24 ) / 100 );
***
Thx for any help.
