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) "\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"\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"\x00", STR_PAD_RIGHT); } function GetPixelColor(&$img, $x, $y) { if (!is_resource($img)) { return false; } 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

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
