Code analysis on generating ICO icons using PHP based on the yii framework

This article shares with you two codes for generating ICO icons in PHP. The first one is based on the YII framework, and the second one is written in pure PHP. They are both very good. Friends in need can refer to it

1, phpthumb_ico is the class that generates ICO icons, the source code is as follows

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); // BITMAPINFOHEADER - 40 bytes $BitmapInfoHeader[$key] = ''; $BitmapInfoHeader[$key] .= "\x28\x00\x00\x00"; // DWORD biSize; $BitmapInfoHeader[$key] .= $this->LittleEndian2String($ImageWidths[$key], 4); // LONG biWidth; // The biHeight member specifies the combined // height of the XOR and AND masks. $BitmapInfoHeader[$key] .= $this->LittleEndian2String($ImageHeights[$key] * 2, 4); // LONG biHeight; $BitmapInfoHeader[$key] .= "\x01\x00"; // WORD biPlanes; $BitmapInfoHeader[$key] .= chr($bpp[$key])."\x00"; // wBitCount; $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00"; // DWORD biCompression; $BitmapInfoHeader[$key] .= $this->LittleEndian2String($biSizeImage, 4); // DWORD biSizeImage; $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00"; // LONG biXPelsPerMeter; $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00"; // LONG biYPelsPerMeter; $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00"; // DWORD biClrUsed; $BitmapInfoHeader[$key] .= "\x00\x00\x00\x00"; // DWORD biClrImportant; } $icondata = "\x00\x00"; // idReserved; // Reserved (must be 0) $icondata .= "\x01\x00"; // idType; // Resource Type (1 for icons) $icondata .= $this->LittleEndian2String(count($gd_image_array), 2); // idCount; // How many images? $dwImageOffset = 6 + (count($gd_image_array) * 16); foreach ($gd_image_array as $key => $gd_image) { // ICONDIRENTRY idEntries[1]; // An entry for each image (idCount of 'em) $icondata .= chr($ImageWidths[$key]); // bWidth; // Width, in pixels, of the image $icondata .= chr($ImageHeights[$key]); // bHeight; // Height, in pixels, of the image $icondata .= chr($totalcolors[$key]); // bColorCount; // Number of colors in image (0 if >=8bpp) $icondata .= "\x00"; // bReserved; // Reserved ( must be 0) $icondata .= "\x01\x00"; // wPlanes; // Color Planes $icondata .= chr($bpp[$key])."\x00"; // wBitCount; // Bits per pixel $dwBytesInRes = 40 + strlen($icXOR[$key]) + strlen($icAND[$key]); $icondata .= $this->LittleEndian2String($dwBytesInRes, 4); // dwBytesInRes; // How many bytes in this resource? $icondata .= $this->LittleEndian2String($dwImageOffset, 4); // dwImageOffset; // Where in the file is this image? $dwImageOffset += strlen($BitmapInfoHeader[$key]); $dwImageOffset += strlen($icXOR[$key]); $dwImageOffset += strlen($icAND[$key]); } foreach ($gd_image_array as $key => $gd_image) { $icondata .= $BitmapInfoHeader[$key]; $icondata .= $icXOR[$key]; $icondata .= $icAND[$key]; } return $icondata; } function LittleEndian2String($number, $minbytes=1) { $intstring = ''; while ($number > 0) { $intstring = $intstring.chr($number & 255); $number >>= 8; } return str_pad($intstring, $minbytes, "\x00", STR_PAD_RIGHT); } function GetPixelColor(&$img, $x, $y) { if (!is_resource($img)) { return false; } return @ImageColorsForIndex($img, @ImageColorAt($img, $x, $y)); } }

2, background

Introduction class:

Yii::$enableIncludePath = false; Yii::import ( 'application.extensions.ico.phpthumb_ico', 1 );

Solve the problem of generating black background

imagealphablending($resize_im, false);//Do not merge colors, directly replace with $im image color, Include transparent color
imagesavealpha($resize_im, true);//Don’t lose the transparent color of $resize_im image
