Convert an image to a Macintosh® icon

An interesting feature of Axialis IconWorkshopä is to create an icon from an existing file. Some image formats support 32 BPP alpha channel transparency which is very interesting to create hi-quality RGB/A images in icons. The following image formats are supported:

Open the image file in Axialis IconWorkshop™

1. Choose "File/Open", browse your folders and select your file (Windows® standard dialog box).

or

Choose "File/New/File File Browser" or press Ctrl+Shift+O. A built-in Axialis file explorer window opens. Browse your disks, see the thumbnail preview and double-click the image file you wish to open.

or

In the Recently Used zone (in the main toolbar), type the full pathname of the image file you wish to open then hit Enter.

2. The image file opens in a document window.

Axialis IconWorkshop™ will convert images to 32 bpp with transparency when possible. This is much more convenient to create icons. The following image formats can include transparency: Photoshop® PSD, PNG, RGB, GIF, JPEG 2000 and WMF.

Add transparency

Transparency is important when creating icons. It permits to display an icon over a background image without fully hiding it. Parts of the background image are visible through the transparent areas of the icon. Transparency can be total (1-bit mask, in GIF for example) or partial (8-bit mask, a.k.a Alpha Channel, in PNG or JPEG2000 for example). Partial transparency (RGB/Alpha Channel) produces better results when displaying icons. See what is an icon to learn more.

The following image formats support transparency: Photoshop® PSD, PNG, RGB, JPEG 2000 and WMF. GIF support only total transparency. Axialis IconWorkshop™ permits to convert images to 32 BPP (RGB/Alpha Channel) which is much more convenient to create icons.

If your image already contains transparency or don't want to use transparency, go directly to step 6.

3. To add your own transparency, choose the "Create Transparent Areas" Mode: or press "T". Click in the areas where you want to create transparency.

4. For example, the illustration below shows the image "Librarian/Media Files/Images/Smiley.jpg". It is JPEG, so it does not contains transparency (only JPEG 2000 supports transparency). The background is white () and fully opaque. If you create an icon from this image, it will create a white square around the final icon, which is not the desired result.

5. In Transparent Area mode, click in the white background (). It is automatically converted to a transparent area (the grey chessboard texture ). You can repeat the operation to create a sharper frontiere around the smiley circle:

When you create a transparent area, the image is automatically converted in 32-bit color depth (RGB / Alpha Channel).

Create an icon from this image

6. Before proceeding, we recommend you to select the portion of image you whish to use to create your icon. If you leave too many transparent areas around your image, the visible part of your icon will be too small.

7. Select the portion of image: Use the selection tool (upper-left button of the tool palette) and select the portion of image you whish to use (do not cut the shadow if there is one around the object). When done, an animated dashed rectangle has been created.

8. When the selection is done, choose Image/Create Macintosh® Icon from Selection or press "M" or click the first command button in the local toolbar ():

9. The dialog box New Macintosh® Icon From Image opens (see below). In the Name group (), enter the icon project name. Do not specify any extension.

10. In the Image Formats group, select the image formats you whish to add in the icon ( to ) and unselect the unwanted images. Just click on the image preview to select/unselect.

11. In the Other group, select the optional image formats you whish to add in the icon (). Note that the 32x32 mono is recommended if you want the icon to be compatible with older systems. The format 256x256 works only under Macintosh® OSX 10.4 (Tiger) or more. The format 512x512 works only under Macintosh® OSX 10.5 (Leopard) or more. The following table shows the common Macintosh® image formats:

12. To get the best results possible, you can also apply a filter when resizing RGB/A images and a dithering option to the 256/16 color images (try and see the results in the preview images).

13. When done, click OK. The icon is automatically created with the various image formats you've selected.
