When creating structured graphics in Illustrator for use in Adobe Flex®, you can save in the FXG format. FXG is a graphics file format based on a subset of MXML, the XML-based programming language used by the Flex framework. You can use FXG files in applications such as Adobe Flash Builder/Adobe Flash Catalyst to develop rich Internet applications and experiences. When saving as FXG, images must be under 16,777,216 total pixels and less than 8192 pixels in width or height.
For more information on using these formats, see the Adobe Flex website at www.adobe.com/products/flex.
You can directly import both Illustrator(.ai) and FXG (.fxg) documents in Flash Catalyst. To import specific Flash Catalyst content in Illustrator, use the Edit in Illustrator option available in Flash Catalyst. However, some of the objects or attributes are treated differently in Illustrator and Flash Catalyst. Using the FXG options, you can control the conversion of these objects and attributes. In addition to this option, you can also paste Illustrator content directly into Flash Catalyst.
When saving content in FXG format in Illustrator, any object or attribute that is not compatible with the FXG specifications is expanded, rasterized, outlined, or dropped based on the complexity of the content and the FXG mapping. For example, to preserve the artwork with 3D effect, which is not supported in FXG, the content is rasterized to save in FXG format.
For a list of object and attribute mapping between Illustrator and FXG, see FXG mapping of Illustrator objects and attributes.
Use the following guidelines while saving Illustrator files in FXG format and editing them in Flash Catalyst:
Use Flash Catalyst or Basic RGB profile for creating content for FXG.
Avoid using brushes as it may cause performance issues due to expanded paths.
FXG provides mapping only for Drop Shadow, Inner/Outer Glow, and Blur, so
prefer these effects over others.Avoid horizontal or vertical scaling of text to avoid outlining when saving to FXG.
FXG does not support blends on filters. If you need to save FXG with filters editable or auto-save option, ensure that you set blend to Normal while applying filters (Drop Shadow, inner/outer glow) on any object for accurate appearance.
In most cases, items created in Illustrator are rendered as pixel-snapped in Flash Catalyst to make horizontal or vertical stroke edges look sharp. To avoid content from shifting between Illustrator and Flash Catalyst, select the Align to Pixel Grid option while working in Illustrator. For more information about aligning objects to the pixel grid, see Drawing pixel-aligned paths for web workflows.
Objects with a blend mode other than normal that are blended against the default document background may display differently in Flash Catalyst. Objects with non-normal blend modes should always have another object behind them.
Skewed items are not supported, and may be positioned differently when imported to Flash Catalyst.
9-slice scaling grids are not supported in Flash Catalyst.
Reflected bitmaps and symbols are not supported in Flash Catalyst.
Spot and process colors are not supported in Flash Catalyst.
Vertical text is not supported in Flash Catalyst.
Warning messages are displayed to guide you about specific data modifications to the selected object or attributes. However, in some cases, the warning message may not be relevant to you. For example, a warning message such as "Some open type properties are dropped' when you deliberately set the language to a value other than
USA . These warning messages about content editability are displayed only if the Save Illustrator Private Data option is selected.
To map Illustrator content in FXG while preserving maximum appearance and editability, you can save a document in FXG format. This document can then be opened in either Illustrator or Flash Catalyst.
-
In the FXG Options dialog box, set the required options. The options available in this dialog box are:
Save Illustrator Private Data
This option is selected by default. It enables better re-editability, when you import FXG files in Illustrator:
It allows maximum editability of FXG files, if you import these files in Illustrator.
note: This option does not guarantee that all the content would be supported in the native Illustrator format. For example, brush strokes are not preserved because there is no support for retention of Illustrator private data for brush strokes. However, effects are preserved live on FXG import through Illustrator private data.
Include Unused Symbols
Use this option to keep or discard unused symbols in the FXG file. Saving unused symbols in FXG may increase the file size.
Downsample Linked Images (72 ppi)
Use this option for downsampling linked image files at 72 ppi, which is the standard web requirement.
Filters
Drop Shadow, Inner Glow, Outer Glow, and Gaussian Blur are supported as filters in FXG. Illustrator provides a trade-off between appearance and editability for these filters, when exported. If you want to preserve editability of these filters with some loss of appearance, select Maintain Editability (Convert to FXG). If you prefer appearance over editability, select the other options: Preserve Appearance (Expand), Preserve Appearance (Rasterize).
Text
To retain the appearance and maintain the editing capability, select the Automatic Conversion option. If editability cannot be maintained for the selected artwork, it is either expanded or rasterized to preserve appearance. To preserve visual appearance of text, select the Preserve Appearance (Rasterize) option or Preserve Appearance (Create Outline) to convert to Vector Outline for smaller file size. For maximum editability of text, select Maintain Editability (Convert to FXG). However, this option may result in loss of appearance.
Gradients
Gradients are not fully compatible with FXG when the gradient has more than 16 stops. Gradient mid points that are not equal to 50% are also mapped directly into FXG. Illustrator first tries to extrapolate those midpoints to actual stops and if they cannot be extrapolated, gradients are rasterized.
Illustrator has the capability to determine the priority when exporting gradients in FXG. If content editability is high priority, then select Maintain Editability (Convert to FXG). Select the Automatic Conversion option to preserve visual appearance and maintain the editing capability. Automatic conversion analyses and determines if content can be kept editable and still match the appearance. If keeping the content editable does not match the appearance then the art is rasterized.
Blend
You can rasterize to preserve the appearance, by selecting Preserve Appearance (Rasterize) or select Automatic Conversion to allow Illustrator to automatically expand or rasterize the blending options based on the complexity of the blend.
FXG is always saved with the Use Artboards option enabled. Artboards are imported as states in Flash Catalyst.
Note:
The artboard range specified while saving FXG content decides the creation of pages or states for Flash Catalyst. If you save a document with multiple artboards in FXG format, any content that lies completely outside the artboard is not saved.
To import or open an FXG file in Illustrator, click File > Open and select the .fxg file.
You can also open an FXG file in Illustrator by selecting the Edit in Illustrator option in Flash Catalyst. For more information, see Round-trip editing of artwork in Adobe Flash Catalyst documentation.
Note:
You cannot link FXG content in Illustrator, you can only embed it.
To edit objects and attributes of an FXG file in Flash Catalyst, use the Edit in Illustrator option in Flash Catalyst. The selected objects are opened in Illustrator. After you finish editing in Illustrator, the object is reconverted to the FXG format, and passed back to Flash Catalyst.
You can edit an FXG file object in Illustrator, while working on the file in Flash Catalyst. To edit an object in Illustrator:
-
Right-click on the object, and then select the Edit in Adobe Illustrator CS5 option.
Choose Modify > Edit in Adobe Illustrator CS5.
Illustrator CS5 opens and the corresponding FXG file is automatically opened for editing. At the upper-left corner of the Illustrator window, the Done and Cancel options are available.
Done and cancel options for FXG file opened in Illustrator
Note:
In Illustrator, only the selected objects are available for editing. All other objects are visible, but cannot be edited.
-
Exit this mode by clicking the Done button at the upper-right corner in Illustrator.
When you click Done, the edited object and any new objects are reconverted into FXG format and passed back to Flash Catalyst.
If you click cancel, a dialog box is displayed to confirm that you do not want to save the changes made to the file.
Dialog box to confirm cancellation of edit in Illustrator
Flash Catalyst uses the FXG (.fxg) format files to create rich Internet applications and experiences. You can use content between Illustrator and Flash Catalyst in three ways:
Import a .ai file directly in Flash Catalyst.
Import a .fxg file in Flash Catalyst, which was saved as .fxg in Illustrator.
Copy any object from Illustrator and paste it into a Flash Catalyst document.
For more information, see Round-trip editing of artwork in Adobe Flash Catalyst documentation.
When you copy and paste content into Flash Catalyst, certain objects and their attributes may not be compatible with the FXG specification. You can specify settings to manually control and preserve visual appearance, editability, or both.
To paste an Illustrator object in Flash Catalyst:
-
In the Illustrator Import Options dialog box, specify the correct options as stated in step 4 of Save an Illustrator file in FXG format.
