TYPO3产生不同尺寸的图像 [英] TYPO3 Produce images in different sizes

问题描述

我有此实现，可在第2级页面子菜单中使用它.每个2级菜单都有多个子页面.每个子页面都有一个图像.因此，此实现会为每个子菜单从每个页面生成一个图像.例如，一个包含2个子页面的子菜单将具有2张图像(每个子页面一个图像).

I have this implementation, using it in a page level 2 submenu. Each level 2 menu has multiple subpages. Each subpage has one image. So this implementation produces an image from each page for each submenu. For example, a submenu with 2 subpages will have 2 images (one from each subpage).

1 = FILES
1 {
    references {
        table = pages
        fieldName = media
        data = levelmedia:-1, slide
    }

    begin = 0
    maxItems = 2

    renderObj = COA
    renderObj {
        2 = IMAGE
        2 {
            file {
                //params = -sharpen 50  +profile "*" -quality 100
                import.data = file:current:uid
                treatIdAsReference = 1
                width.optionSplit = 300c|*|400c
                height.optionSplit = 350c|*|450c
            }
        }
    }
}

希望将图像裁切成不同的大小，以便将图像1裁切成与图像2不同的尺寸，依此类推.

Would like to have images cropped in different sizes such that image 1 is cut to different dimensions from image 2 and so on.

我的ImageMagick安装可完美运行.实际上是用它毫无障碍地裁剪单个图像.

My ImageMagick installation works perfectly. Am actually cropping single images with it without a hitch.

如果没有上面的optionSplit，图像将被正确地切成大小.不幸的是，使用optionSplit只能输出原始尺寸的图像.

Without the optionSplit above, the images are cut to size nicely. Unfortunately with the optionSplit it simply outputs the images in their original sizes.

如何产生不同的图像尺寸?我的理解是，optionSplit是解决方法(来自手册).我读过一些文章，其中soureCollection用于响应图像使用optionSplit.我想象另一种方式是使用图像注册计数器并使用CASE来确定如何剪切图像1、2、3等，但是不熟悉注册计数器(也许有人可以向我展示如何执行此操作?).还有另一种方法是使用文件/图像索引号，但是我尝试了数小时的手册来查找这样的指针，并且如果有任何帮助的地方，它在任何地方都没有列出.有人知道这样做的方法吗?

How can I produce different image sizes? My understanding is that optionSplit is the way to go (from the manuals). I read in articles that soureCollection for responsive images use optionSplit. I imagine another way would be to use an image register counter and use CASE to determine how to cut image 1, 2, 3 and so on, but am not familiar with register counters (maybe someone can show me how to do this?). And yet another way would be to use a file/image index number but I've tried looking at the manuals for hours for such a pointer and nowhere is it listed if there's any to help with processing. Anybody know a way to do this?

推荐答案

在打字稿中很难渲染两个具有不同参数的连续图像:
您的optionsplit不能成功，因为在renderObj中您始终只有一个文件.所有renderObj的坏习惯.

rendering two consecutive images with different paramters will be difficult in typoscript:
your optionsplit can not success as in the renderObj you always have only one file. A bad habit of all renderObj.

:没有属性optionSplit.该功能是在任何wrap属性中构建的.

on the other hand: there is no property optionSplit. the functionality is build in any wrap property.

因此，打字稿中的处理方法是将元素连接起来，然后再次拆分它们，然后在拆分的renderObj中使用不同的选项来分别处理它.
或使用寄存器变量实现计数器，然后评估寄存器以设置不同的值.

therefore a handling in typoscript could be to concatenate the elements, then split them again, but then use different options in the split renderObj to handle it separately.
or implement a counter with a register variable, then evaluate the register to set different values.

更容易处理，可以在f:for viewhelper中使用迭代器，然后在{iterator.index}上执行f:if(对于两种情况)或f:switch(对于更多情况).呈现单个版本.

easier would be a handling in fluid, where you could use an iterator with the f:forviewhelper, and then do an f:if (for two cases) or an f:switch (for more cases) on {iterator.index} to render individual versions.
