I've created a helper for image upload, and I have an exercise that I need to use imagecreatetruecolor, but I do not quite understand what the official documentation provides:
Cria uma nova imagem true color
imagecreatetruecolor() retorna um identificador de imagem representando uma imagem preta de tamanho x_size por y_size.
How do you handle image?
In short we could say that:
The functions below are part of the GD library, which in turn was developed for the treatment of images. It is a library open source for dynamic image creation by programmers. The library creates PNG, JPEG and GIF, among other formats it is usually used to generate graphics, thumbnails, banners ...
According to the official documentation , syntax:
resource imagecreatetruecolor ( int $width , int $height )
imagecreatetruecolor () returns an identifier that represents a black image of the specified size. In short:
imagecreatetruecolor ($largura ,$altura )
It takes two parameters, both are integers and returns a resource that will be used by other methods to continue the work of constructing an image.
See an example contained in official documentation :
<?php
header ('Content-Type: image/png');
$im = imagecreatetruecolor(120, 50)
or die('Cannot Initialize new GD image stream');
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, 'Issoé um teste', $text_color);
imagepng($im);
imagedestroy($im);
