Hi all, I wonder whether Graphiti supports custom image as shape or not. I want to create components arrangement. Each component already has its own image defined. So, what I need is to arrange those image in Graphiti editor.

Thanks in advance.

Emerson,

there's a graphics algorithm image available, so instead of e.g. a rectangle
with text you could use that.

Hi Wenz,

I don't understand how to use your instruction. I looked down the the gaService instance of Graphiti. I create an Image instance using "createImage(containershape,stringid)". I lost it when I didn't found any function related to how to set the picture url. Can you point me a code snippet to insert an image?

Thanks and regards.
Emerson

Emerson,

images have an ID that is used from within a diagram and defined within the
image provider. The tutorial page
http://help.eclipse.org/juno/index.jsp?topic=%2Forg.eclipse.graphiti.doc%2Fresources%2Fdocu%2Fgfw%2Fimages.htm&cp=27_1_6
should give you an idea how to handle them.

index.php/fa/13447/0/
What I want to achieve is described by picture above. I try to add image instance like this:
Image image = gaService.createImage(containerShape, GraphBTImageProvider.IMG_EREFERENCE);


But nothing happens, even the green box was not drawn. However, I tried to apply the registered image id (GraphBTImageProvider.IMG_EREFERENCE) to a ContextButton and it appeared. I think, the tutorial is not what I looking for (but still essential), or maybe I am mistaken something in using the registered image to a pictogram element.

Emerson,

Sorry for the late reply, this somehow dropped in the depths of the forum...

Are the sizes set correctly for the image? Default is 0, so nothing
appears. Also you may need to set stretch/proportional flags on the image
depending on the size.

Thanks Michael, now it works Smile

However, to make sure I will use the feature, I want to ask, can I add/register the picture at run time. E.g, user just added a picture through a form, then, he opens the Graphiti editor. At that time, the picture shows up in the palette, ready to be included in the canvas. If this is not possible, maybe I will code the feature myself. But, if it is possible, I'll worship Graphiti for make me save my precious hours.

Thanks as always.
Emerson

Emerson,

basically, the image provider manages a hash map containing ids and paths
for your images. You should be able to call addImageFilePath also after the
user added the picture. What you would need to care about yourself would be
removal of images in case you want to support that as well.
