本文给大家分享了2则php生成ICO图标的代码,第一款是基于YII框架实现的,第二款是纯php编写,都非常的不错,有需要的小伙伴可以参考下
1,phpthumb_ico 是生成ICO图标的类,源码如下
- class phpthumb_ico {
- function phpthumb_ico() {
- return true;
- }
- function GD2ICOstring(&$gd_image_array) {
- foreach ($gd_image_array as $key => $gd_image) {
- $ImageWidths[$key] = ImageSX($gd_image);
- $ImageHeights[$key] = ImageSY($gd_image);
- $bpp[$key] = ImageIsTrueColor($gd_image) ? 32 : 24;
- $totalcolors[$key] = ImageColorsTotal($gd_image);
- $icXOR[$key] = '';
- for ($y = $ImageHeights[$key] - 1; $y >= 0; $y--) {
- for ($x = 0; $x < $ImageWidths[$key]; $x++) {
- $argb = $this->GetPixelColor($gd_image, $x, $y);
- $a = round(255 * ((127 - $argb['alpha']) / 127));
- $r = $argb['red'];
- $g = $argb['green'];
- $b = $argb['blue'];
- if ($bpp[$key] == 32) {
- $icXOR[$key] .= chr($b).chr($g).chr($r).chr($a);
- } elseif ($bpp[$key] == 24) {
- $icXOR[$key] .= chr($b).chr($g).chr($r);
- }
- if ($a < 128) {
- @$icANDmask[$key][$y] .= '1';
- } else {
- @$icANDmask[$key][$y] .= '0';
- }
- }
- // mask bits are 32-bit aligned per scanline
- while (strlen($icANDmask[$key][$y]) % 32) {
- $icANDmask[$key][$y] .= '0';
- }
- }
- $icAND[$key] = '';
- foreach ($icANDmask[$key] as $y => $scanlinemaskbits) {
- for ($i = 0; $i < strlen($scanlinemaskbits); $i += 8) {
- $icAND[$key] .= chr(bindec(str_pad(substr($scanlinemaskbits, $i, 8), 8, '0', STR_PAD_LEFT)));
- }
- }
- }
- foreach ($gd_image_array as $key => $gd_image) {
- $biSizeImage = $ImageWidths[$key] * $ImageHeights[$key] * ($bpp[$key] / 8);

- $icondata = "/x00/x00"; // idReserved; // Reserved (must be 0)

- $icondata .= $this->LittleEndian2String(count($gd_image_array), 2); // idCount; // How many images?

- return @ImageColorsForIndex($img, @ImageColorAt($img, $x, $y));
- }
- }
2,后台
引入类:
- Yii::$enableIncludePath = false;
- Yii::import ( 'application.extensions.ico.phpthumb_ico', 1 );
解决生成黑色背景的问题
imagealphablending($resize_im, false);//不合并颜色,直接用$im图像颜色替换,包括透明色
imagesavealpha($resize_im, true);//不要丢了$resize_im图像的透明色
