如何显示使用PHP GD动态生成的嵌入式图像 [英] How to display an inline image generated on the fly using PHP GD
问题描述
我正在尝试通过使用PHP GD合并图像来动态生成图像.我想知道是否有一种方法可以在网页内显示图像,而无需将其存储在服务器上的某个位置.
I am trying the generate an image on the fly by merging images using PHP GD. I want to know if there is a way I can display the image inside my webpage without the need of storing it somewhere on server.
例如,我创建了以下代码来合并图像...
Like for example I created the following code for merging the images...
function create_image() {
$main_image = imagecreatefrompng("images/main.png");
$other_image = imagecreatefrompng("images/other.png");
imagecopy($main_image, $other_image, 114, 53, 0, 0, 49, 34);
imagepng($main_image);
imagedestroy($other_image);
}
现在我的html代码到现在为止...
Now my html code till now was...
<div class="sidebar-avatar">
<img src="avatar_pattern.png" class="pattern1" width="430" height="100" />
</div>
我应该如何调用php函数,以便它显示在我为其指定的div中生成的图像.
How should I call the php function so that it displays the image generated in the div I have designated for it.
更新:我发现使用了Content-type: image/png
,但这意味着我将不得不在非内联的单独页面上显示图像.
Update: I found the use of Content-type: image/png
but that would mean I will have to display the image on a separate page not inline.
推荐答案
使用base64_encode将其转换为Base64,并将其作为img标签中的dataURI回显!
Convert it to Base64 with base64_encode and echo it as a dataURI in an img tag !
