ecshop后台添加商品相册的时候bmp格式的无法生成缩略图

ecshop bmp

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！

回复讨论(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

我 想要的就是让ecshop支持这种生成图！咋办呢本文来源gaodaimacom搞#^代%!码&网*

你可下载一个 ImageCreateFromBMP.php
然后改一下你的程序

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' . 			'/Vcompression/Vsize_bitmap/Vhoriz_resolution' . 			'/Vvert_resolution/Vcolors_used/Vcolors_important' , fread ( $f1 , 40 )); 	$BMP [ 'colors' ] = pow ( 2 , $BMP['bits_per_pixel ' ]); 	if ( $BMP ['size_bitmap'] == 0 ) $BMP ['size_bitmap']=$FILE ['file_size']-$FILE ['bitmap_offset']; 	$BMP ['bytes_per_pixel'] = $BMP ['bits_per_pixel'] / 8 ; 	$BMP ['bytes_per_pixel2'] = ceil ( $BMP ['bytes_per_pixel']); 	$BMP ['decal'] = ( $BMP ['width']*$BMP ['bytes_per_pixel'] / 4 ); 	$BMP ['decal'] -= floor ( $BMP ['width'] * $BMP ['bytes_per_pixel'] / 4 ); 	$BMP ['decal'] = 4 - ( 4 * $BMP ['decal']); 	if ( $BMP ['decal'] == 4 ) $BMP ['decal'] = 0 ; 	// 3 : Chargement des couleurs de la palette 	$PALETTE = array (); 	if ( $BMP ['colors'] = 0 ){ 		$X = 0 ; 		while ( $X > 4 ) ; 				else 					$COLOR [1] = ( $COLOR [1] & 0x0F ); 				$COLOR [1] = $PALETTE [ $COLOR [1] + 1 ]; 			}elseif ( $BMP['bits_per_pixel']== 1 ){ 				$COLOR = unpack ( "n" , $VIDE . substr ( $IMG , floor ( $P ) , 1 )); 				if (( $P * 8 ) % 8 == 0 ) $COLOR [ 1 ] = $COLOR [ 1 ] >> 7 ; 				elseif (( $P * 8 ) % 8 == 1 ) $COLOR [1] = ( $COLOR [1] & 0x40 ) >> 6 ; 				elseif (( $P * 8 ) % 8 == 2 ) $COLOR [1] = ( $COLOR [1] & 0x20 ) >> 5 ; 				elseif (( $P * 8 ) % 8 == 3 ) $COLOR [1] = ( $COLOR [1] & 0x10 ) >> 4 ; 				elseif (( $P * 8 ) % 8 == 4 ) $COLOR [1] = ( $COLOR [1] & 0x8 ) >> 3 ; 				elseif (( $P * 8 ) % 8 == 5 ) $COLOR [1] = ( $COLOR [1] & 0x4 ) >> 2 ; 				elseif (( $P * 8 ) % 8 == 6 ) $COLOR [1] = ( $COLOR [1] & 0x2 ) >> 1 ; 				elseif (( $P * 8 ) % 8 == 7 ) $COLOR [1] = ( $COLOR [1] & 0x1 ); 				$COLOR [1] = $PALETTE [ $COLOR [1] + 1 ]; 			}else return FALSE ; 			imagesetpixel( $res , $X , $Y , $COLOR [ 1 ]); 			$X ++ ; 			$P += $BMP['bytes_per_pixel']; 		} 		$Y -- ; 		$P += $BMP['decal']; 	} 	// Fermeture du fichier 	fclose ( $f1 ); 	return $res ; }
