問題描述

目前正在使用 PHP 和 iMagick 開發(fā)海報(bào)打印 Web 應(yīng)用程序.

Currently working with PHP and iMagick to develop a poster printing Web application.

這是我用來測(cè)試應(yīng)用程序的上傳/圖像編輯功能的示例圖像:

This is the example image I am using to test upload/image editing features of the application:

圖像包含以下 EXIF 數(shù)據(jù):

The image contains the following EXIF data:

[FileName] => 1290599108_IMG_6783.JPG
    [FileDateTime] => 1290599109
    [FileSize] => 4275563
    [FileType] => 2
    [MimeType] => image/jpeg
    [SectionsFound] => ANY_TAG, IFD0, THUMBNAIL, EXIF, INTEROP, MAKERNOTE
    [COMPUTED] => Array
        (
            [html] => width="3504" height="2336"
            [Height] => 2336
            [Width] => 3504
            [IsColor] => 1
            [ByteOrderMotorola] => 0
            [CCDWidth] => 22mm
            [ApertureFNumber] => f/5.6
            [UserComment] => 
            [UserCommentEncoding] => UNDEFINED
            [Thumbnail.FileType] => 2
            [Thumbnail.MimeType] => image/jpeg
        )

    [Make] => Canon
    [Model] => Canon EOS 30D
    [Orientation] => 6
    [XResolution] => 72/1
    [YResolution] => 72/1
    [ResolutionUnit] => 2
    [DateTime] => 2009:08:31 08:23:49
    [YCbCrPositioning] => 2
    [Exif_IFD_Pointer] => 196

然而 - iMagick，當(dāng)使用這個(gè)圖像 __construct' 時(shí)，會(huì)根據(jù) [Orientation] => 自動(dòng)將其逆時(shí)針旋轉(zhuǎn) 90 度.6(我想！).導(dǎo)致這個(gè)...

However - iMagick, when __construct'ed with this image, automatically rotates it an additional 90 degrees CCW as per [Orientation] => 6 (I think!). Resulting in this...

我想知道的是...

如何保持在頁面頂部看到的圖像的原始方向?這是否可以通過禁用 iMagick 執(zhí)行的自動(dòng)旋轉(zhuǎn)來實(shí)現(xiàn)?

How can I maintain the original orientation of the image seen at the top of the page? And is this possible through disabling the auto-rotation performed by iMagick?

非常感謝

更新:這是我想出的解決方案......它將根據(jù) EXIF 數(shù)據(jù)中的方向修復(fù)方向

   public function fixOrientation() {

       $exif = exif_read_data($this->imgSrc);
       $orientation = $exif['Orientation'];
       switch($orientation) {

           case 6: // rotate 90 degrees CW
               $this->image->rotateimage("#FFF", 90);
           break;

           case 8: // rotate 90 degrees CCW
              $this->image->rotateimage("#FFF", -90);
           break;

       }

 }

推薦答案

嘗試 Imagick::setImageOrientation.試驗(yàn)可用常量.

這篇關(guān)于如何停止基于 EXIF“方向"數(shù)據(jù)的 PHP iMagick 自動(dòng)旋轉(zhuǎn)圖像的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
