ecshop后台添加商品相册的时候bmp格式的无法生成缩略图ecshop后台批量生成图片商品相册的时候bmp格式的无法生成缩略图求怎么解决? 我想达到的效果就是能够生成bmp格式的图片! ecshop bmp 分享到: ------解决方案--------------------ecshop本身不支持bmp图像生成缩微图。你要先转换为gif/jpg/png其中一种------解决方案--------------------你可下载一个 ImageCreateFromBMP.php 然后改一下你的程序------解决方案-------------------- 引用: Quote: 引用: ecshop本身不支持bmp图像生成缩微图。你要先转换为gif/jpg/png其中一种 我 想要的就是让ecshop支持这种生成图!咋办呢? includes/cls_image.php是ecshop的图片处理库,你可以用ImageCreateFromBMP这个函数自行扩展 function ImageCreateFromBMP( $filename ) { // Ouverture du fichier en mode binaire if ( ! $f1 = @fopen ($filename, "rb")) return FALSE ; // 1 : Chargement des ent?tes FICHIER $FILE = unpack ( "vfile_type/Vfile_size/Vreserved/Vbitmap_offset" , fread($f1 ,14)); if ( $FILE ['file_type'] != 19778 ) return FALSE ; // 2 : Chargement des ent?tes BMP $BMP = unpack ( 'Vheader_size/Vwidth/Vheight/vplanes/vbits_per_pixel' .
