= Copying and pasting diagrams and images in diagrams =

* Copying or exporting a diagram: When viewing a diagram, you can save a copy of the diagram as an image, choosing PNG, JPG, or EMF image format, using the '''Export...''' option from the '''File''' menu.

* New image formats: It now handles compressed image formats for images pasted into nodes or diagrams, including PNG, JFIF or JPEG, TIF, and GIF, as copied into the clipboard from another application. When you paste from the clipboard into an Analytica node or diagram, it retains the same format. Some applications, including Internet Explorer, copy images in an uncompressed bitmap format to the clipboard. In those cases, Analytica 4.1 compresses the image into  PNG format in order to reduce memory usage and model file size.

* Images pasted into Analytica 4.1 now render virtually instantaneously, even when pasted from large bitmap images that could often take many seconds to redraw in previous releases.

* It also supports 32-bit bitmap images with an alpha color transparency channel.

* Forward compatibility: Models with images created with previous releases may still contain uncompressed bitmap images. These will display in Analytica 4.1, but won't benefit from the smaller image sizes or faster redraws. To obtain these benefits, you should copy and paste these images again in Analytica 4.1.

* Backward compatibility: Compressed format images added with Analytica 4.1 will not display if you run the model with an older release of Analytica. EMF (metaformat images) are unaffected and work in both directions. To convert an image pasted in 4.1 into the ''Legacy Bitmap'' format that will display in 4.0 and earlier, or to compress a legacy bitmap from an older model so it takes up less space, there is a new '''Change Picture Format...''' dialog accessible from the '''Diagram''' menu.

* You can now copy images from an Analytica diagram or node, which previously was unreliable.

* The ''Pict'' attribute: Those interested can now view the image format (such as PNG, EMF, etc) and size, as stored within Analytica, in the Pict attribute. You can view this attribute in the Typescript, if you type '''Show Pi1''' or '''Pict Pi1''', where ''Pi1'' is a node containing a picture.  Formerly it just said "(Non-ASCII data)".
