Get Image from Image Gallery in a portlet plugin

[Mario Muñoz，修改在15 年前。]

Hi,

I'd like to show an image saved within the image gallery portlet in my custom portlet application. I've been searching the API, but it seems too confusing. Can anybody provide an example of accesing images from image gallery?

Thanks.

Mario.

Iterating over and displaying images in an IGFolder:

	<%
         long folderId = ...

	IGFolder folder = IGFolderServiceUtil.getFolder(folderId);

	List images = IGImageLocalServiceUtil.getImages(folder.getFolderId());

	for	(int i = 0; i < images.size(); i++) {
		IGImage image = (IGImage)images.get(i);
	%>

		<img src="<%= themeDisplay.getPathImage() %>/image_gallery?img_id=<%=
image.getLargeImageId() %>&amp;t=<%=
ImageServletTokenUtil.getToken(image.getLargeImageId()) %>">

	&lt;%
	}
         %&gt;

Getting a single image and displaying it:

 <%
         long imageId = ...

         IGImage image = IGImageLocalServiceUtil.getIGImage(imageId);
         %>

         <img src="<%= themeDisplay.getPathImage() %
>/image_gallery?img_id=<%= image.getLargeImageId() %>&amp;t=<%=
ImageServletTokenUtil.getToken(image.getLargeImageId()) %>">
 

HTH!

Hi Ray,

I really appreciate your help, it is very useful to me. Now I have one more question: how can I get the imageId? from my portlet application I only have access to the image file name.

Thanks for your reply,

Mario.

Hi again,

I'll answer my own question. I have been able to get the images from Image Gallery using the file name with the IGFolderLocalServiceUti.search(...) method. I have used the file name obtained from my data model to fill the keywords field in the method.

It seems it works pretty well.

Thanks!

Mario.

you can use image gallery to create a folder to save images ,then in igfolder table you can find the folderid , use IGFolderLocalServiceUtil.getFolders(...) or IGImageLocalServiceUtil.getImages(...) . Final you must get the image id ,the rest can be easily handled.

Hello Ray,

Is it possible to give the image id the value of a custom attribute?

Do you mean to manually specify an image id? If so, then no. It's automatically generated.

i've found a solution for my problem: to make a zip with some of the images from the image gallery.

//Image are saved in data base

IGImage im = IGImageLocalServiceUtil.getIGImage(idImagen);
Image image = ImageLocalServiceUtil.getImage(im.getLargeImageId());
byte[] imagen = image.getTextObj();

File ficheroImagen = File.createTempFile(Long.toString(im.getImageId()), im.getImageType());
FileOutputStream fos= new FileOutputStream(ficheroImagen);
fos.write(imagen);
fos.close();

How would you also show/change the star ratings related to an image in a custom portlet?
