Scanning and Configuring OneTouch
Right-click on the BMP icon to access the GIF and PNG image formats. When you select either of these formats, the format panel will change the BMP icon to the selected image format icon.
BMP—the *.bmp (bitmap) format is generally used when you want to do additional image processing, such as photo touch-up or color correction, as very little image compression is used when creating the file. When scanning in color or grayscale, BMP scans result in the largest file size of the image formats.
GIF—the *.gif (graphics interchange format) format is generally used when putting images on a website or server, as image compression can reduce the file size by approximately 95% when compared to a BMP file of the same image. Company logos and small pictures on a webpage are often GIF images. The GIF compression, and limited color range, can result in the medium and large images looking grainy or pixilated.
PNG—the *.png (portable network graphics) format is another common image format for website graphics. Like GIF, the PNG compression greatly reduces the file size when compared to a BMP file of the same image. However, the PNG compression is different from GIF compression in that PNG images look better when scaled. Therefore, PNG is often used in place of GIF for company logos with a lot of detail, clickable buttons, medium sized pictures, and so on.
TIFF—the *.tif (tagged image file format) format is another image type that is often used for photo editing. When scanning in color, it produces a file of similar quality and size to a BMP file. However, when scanning in Black & White, the TIF compression produces the smallest file size of all the image types without losing image quality. TIFF also supports multi-page image files.
JPG—the *.jpg (joint photographic experts group) format is a common image format for transferring pictures electronically, such as posting to a website or sending via email, as JPG image files are smaller than BMP and TIFF files. You can change the level of compression for the picture file to have better quality or a smaller file size.
To select a JPEG file size:
1.Select JPG as the page format.
2.Right-click on the JPG icon. A menu opens.
