equivalente en asp de imagecreatetruecolor php alguien sabe como puedo hacer lo mismo que hace el imagecreatetruecolor en php en asp les paso un codigo que encontre en php que quiero hacer en asp
Código:
<?php
error_reporting(0);
/**
* Get the width and height of the destination image
* from the POST variables and convert them into
* integer values
*/
$w = (int)$_POST['width'];
$h = (int)$_POST['height'];
// create the image with desired width and height
$img = imagecreatetruecolor($w, $h);
// now fill the image with blank color
// do you remember i wont pass the 0xFFFFFF pixels
// from flash?
imagefill($img, 0, 0, 0xFFFFFF);
$rows = 0;
$cols = 0;
// now process every POST variable which
// contains a pixel color
for($rows = 0; $rows < $h; $rows++){
// convert the string into an array of n elements
$c_row = explode(",", $_POST['px' . $rows]);
for($cols = 0; $cols < $w; $cols++){
// get the single pixel color value
$value = $c_row[$cols];
// if value is not empty (empty values are the blank pixels)
if($value != ""){
// get the hexadecimal string (must be 6 chars length)
// so add the missing chars if needed
$hex = $value;
while(strlen($hex) < 6){
$hex = "0" . $hex;
}
// convert value from HEX to RGB
$r = hexdec(substr($hex, 0, 2));
$g = hexdec(substr($hex, 2, 2));
$b = hexdec(substr($hex, 4, 2));
// allocate the new color
// N.B. teorically if a color was already allocated
// we dont need to allocate another time
// but this is only an example
$test = imagecolorallocate($img, $r, $g, $b);
// and paste that color into the image
// at the correct position
imagesetpixel($img, $cols, $rows, $test);
}
}
}
