Image Conversion
JPEG, POISON / JFIF, BMP and TIFF are the most used for storing still image files such as photos, graphics and drawings are used. JPEG stands for Joint Photographic Experts Group and is a standard for compressing images. JPEG is a compression technique for color images, even brilliant, as MPEG is used to compress movie files.
A bitmap file. His memory is limited to 256 colors to 16 million colors in JPEG format.GIFF is therefore better to store images instead of color photographs.
Other popular formats for storing bitmap images are TIFF (Tagged Image File Format), BMP, PCX, y. A bitmap image is a pattern of points (each point with the bits of data) together. Vector graphics are on the other hand, the use of geometric formulas, images. Vectors are more flexible than bitmaps. This leads to the difference between drawing and paint programs. In the painting program designs are represented as bitmaps. Draw programs, on the other images represent as vector graphics.
• Convert files to JPEG compression can greatly GIFF. The uncompressed data is normally 24 bits / pixel for color images. JPEG compression can achieve 20.01 bis 10.01 hours without apparent loss, 30:1 to 50:1 compression with a small mean defect, and 100:1 for very low quality for archival purposes. The storage capacity of these smaller files and less time to spread through networks to increase.
• JPEG files are ideal for archiving images. JPEG files store a wide range of colors (24 bits / pixel compared to 8 bits / pixel GIFF).
Conversion Rules:
• large, high-quality, real-world scanned photos are the best material for conversion to JPEG format.
• Do not convert to black and white images in JPEG format works best with a soft color palette and subtle.
• In color images make sure the sharp edges to smooth the conversion. A grayscale image is much easier for the JPEG format.
• Avoid converting images that have been converted before. Conversion spoils the quality of the images. It is best to be here working with scanned images of the originals. Now close the file
How to convert JPEG third way to reopen the file
Fourth to the File menu, click Save As
Fifth Rename the file in the file name and file type drop box, click the format you want to apply. In this case, “JPEG (*. jpg, *. jpeg,)”
Sixth, click the Save button. Your file is now converted to BMP to JPEG.
If you want to change BMP POISON, follow the same procedure, except that the Save as type, “Graphics Interchange Format (. POISON)” click
Once an image is converted from one format to another, such POISON to JPEG, some information is lost.
