RealZoom for Mac

From Katsura Shareware:

RealZoom generates a somewhat realistic zoomed (close-up) image as if you are taking a close look at your LCD, CRT screen, or paper with a magnifying glass. I hope this is a useful image utility for graphic designers, graphic artists, and for anyone to help understand how images are reproduced on LCD, CRT, and paper.

• Available zoom types: RGB stripes, RGB dots, LCD, Trinitron (Aperture Grille), Shadow Mask, Video (interlace), Black Print (K=0 and 45 degrees), and Color Print (CMYK=0 and 63.4 degrees).
• Supported image files: .tiff, .pdf, .pict, .gif, .jpg, .png, and .icns.
• Save zoomed images as TIFF bitmap image files.
• Drag and drop an image file to the image view.
• Open Recent image files.
• AppleScript scripting

NOTE: RealZoom generates a very large image when the magnification is high (e.g. 6x, 9x, 12x, etc.), and the system may not be able to handle a very large image properly. Please make sure to select a portion of (or scale down) your large image and save a smaller image with your image editing application such as Photoshop, then load the small image with RealZoom. Thanks.
