CHAPTER 36 IMAGE PROXIES Proxies are low-resolution images you can use in Canvas documents. A proxy is a placeholder that is linked to an original image. The orig- inal high-resolution image is stored in a Canvas Image File on disk. Using proxies Proxies can significantly reduce the time required to redraw the screen while you work. Also, a Canvas document that contains prox- ies requires much less disk storage space than one containing high- resolution images (although the space required to store the document and the linked image files is approximately the same as for the docu- ment containing high-resolution images). Replacing an image with a proxy The procedure described in this section lets you replace an image contained in a Canvas document with a low-resolution proxy. When you do this, Canvas exports the original image to a Canvas Image File, and links the Canvas Image File to the proxy. If you later double-click the proxy for editing, Canvas loads the orig- inal image from the Canvas Image File. You can edit the original Tip Proxies are most useful for con- serving time and memory when you use large, high-resolution color images in documents. A low-resolution proxy replaces the image in a Canvas document. The proxy is linked to the Canvas Image File. A high-resolution image stored in a Canvas Image File on disk.
