You will also be able to make a batch of barcode images and make a XML file to be used in Illustrator, using Illustrator XML Creator. Encapsulated PostScript (*.eps) Enhanced MetaFile (*.emf)jk JPEG (*.jpg) PNG (*.png) TIFF (*.tif) Windows Bitmap file (*.bmp) *.eps and *.emf are vector formats, others are bitmap formats. The barcode image was made using the barcode software, Barcode Image Maker Pro, download the barcode software. If you need to edit the vector barcode, then it can be done ease in Adobe Illustrator. Here you can see how tho resize a Encapsulated PostScript (*.eps) barcode in Adobe Illustrator. Adobe Illustrator also supports bitmap images as well. Adobe Illustrator supports all the file formats, but I do recommend using the Encapsulated PostScript (*.eps) as Illustrator is a vectors graphics software. You will be able to edit the Encapsulated PostScript (*.eps) in Illustrator. Both RGB and CMYK can be set/used. Opening an image in Adobe Illustrator is very easy, click on the File menu and then click on Open (Ctrl+O), select the image and it will be added to the page. Select the barcode image and then move the mouse pointer to one of the edges of the image and when the cursor looks like the arrow in the image below If you want to rotate the barcode image 45, 90, 180, 270 then you can do it by holding down the SHIFT key on your keyboard and then move the mouse up or down and the image will rotate (image must be selected as shown in the image above). If you would like to rotate the barcode by filling in the digits for the degree, then do the following. Press the ENTER key (Carriage Return) on you keyboard and the numeric rotate box will show. Fill in the Angle and click on the OK button.
