VAGraphics About Digital Images
Photo restoration always uses raster bitmap images, such as Jpeg, PNG, Tiff, etc. Photographs can be scanned in for digital image enhancement as any hi-resolution raster bitmap, such as BMP, TGA, Jpeg, PNG, Tiff, etc. Graphic design and custom web design don't require raster bitmap image to render an image, however, using digital photos in design is commonly preferred by artist and client alike. Raster bitmap image file formats can save at 16, 24, and 32 bits-per-pixel. At the two highest levels, the pixels themselves can carry up to 16,777,216 different colors. Bitmaps images saved at 24 bits per pixel are great quality images, but of course the file size is triple that of an 8 bit image. Photo repair, photo enhancement, photo retouching, photo restoration and any other type of digital photo editing will require the use of raster bitmap images.
Anyone familiar with the Internet and custom web design recognizes the JPEG bitmap image as a household word. Graphic designers commonly use TIFF bitmap images for print collateral design. Custom web designers almost always use colorful Jpeg photos in their web pages. In a couple years PNG bitmap image format will have replaced the GIF bitmap image in custom web design, and graphic designers may retire Jpeg image format as well, considering the PNG bitmap image format offers so much more than the Jpeg bitmap image format.
There are numberous Raster image formats such as the following:
JPEG Digital Image format -
Joint Photographic
Experts Group
JPG Digital Image format -
(abbreviated is most commonly used ext.)
BMP Digital Image format - Microsft Windows Bitmap
PNG Digital Image format - Portable Network Graphics
GIF Digital Image format - Graphics Interchange
Format
TIFF Digital Image format - Tagged Image File Format
TGA Digital Image format - Targa; Truevision TGA
What Is A Bitmap?
A bitmap is a method of storing digital data that maps a visual image pixel, bit by bit. the pixels are mapped to specified dimensions to create an image. There are numerous bitmapped file formats, .bmp, .jpg, .png, tiff, .tga, .gif, .pcx, .pict, etc. All digital photos are bitmap images. This type of file produces the ´jaggies´ when examined closely. The line of pixels that create edges. Bitmap images are used by all computers. The desktop or screen information for all Windows machines uses .bmp files, while the Macintosh uses pict files.
Compression
Uncompressed bitmap images by nature produce large file sizes, however,
various image compression solutions have been developed to reduce the
file size of bitmap images. The same image saved in GIF or
JPEG
format uses less bytes to make up the file than that of a TIFF or BMP
bitmap image file. How? Compression.
Image compression is used to reduce the amount of memory required to store an image. For example, an image that has a resolution of 800x600 and is in the RGB color space at 8 bits per color requires 900 kbytes of storage. If this image can be compressed at a compression ration of 20:1, the amount of storage required is only 45 kbytes. There are several methods of image compression, including iVEX, JPEG, MPEG, H.261, H.263, and Wavelet. "Compression" is a computer term that represents a variety of mathematical formats used to compress an image's byte size.
Bitmaps can be compressed to a point. The process is called "run-length encoding." Runs of pixels that are all the same color are all combined into one pixel. The longer the run of pixels, the more compression. Bitmaps with little detail or color variance will really compress. Those with a great deal of detail don't offer much in the way of compression. Bitmaps that use the run-length encoding can carry either the common ".bmp" extension or ".rle". Another difference between the two files is that the common Bitmap can accept 16 million different colors per pixel. Saving the same image in run-length encoding knocks the bits-per-pixel down to 8. That locks the level of color in at no more than 256. That's even more compression of bytes to boot.
JPEG Image Formats
JPEG is a compression algorithm developed by the Joint Photographic
Experts Group. JPEG's big selling point is that its compression factor
stores the image on the hard drive in less bytes than the image is when
it actually displays. Bytes are lost at the expense of detail. The Web
took to the format straightaway because not only did the image store in
fewer bytes, it transferred in fewer bytes. Lossy compression achieves
a significant file size reduction while providing very good image
quality. Precise control over compression attributes such as image
quality vs. file size, 8 bit grayscale or 24 bit RGB, etc., is very
useful.
Progressive JPEG Image Format
A progressive JPEG fills in every other line as it loads, then returns
to the top of the image to fill in the remainder.
PNG Image Format
The PNG format was designed to replace the dated GIF format, and to
some extent, the TIFF format. It utilizes lossless compression, meaning
no image data is lost when saving or viewing the image. It is a
universal format that is recognized by the World Wide Web consortium,
and supported by modern web browsers. The PNG format does not have any
patent restrictions and can be read and written freely by software
developers and webmasters alike. The PNG image format can store 32 bit
image data and full 8 bit alpha channels, yet can be compressed much in
the same manner as a Jpeg file.
What about GIF?
GIF images can only be saved as an 8-bit colormapped image, which means
you are limited to 256 colors. Remember the GIF format was developed
back when most PC's only had the capability of 256 colors. PNG can be
saved not only as 8 bit, but also 24 bit and higher up to 64 bit! GIF
images allow one out of the possible 256 colors to be fully
transparent. As we discuss below, PNG has a much higher level of
transparency support. Another benefit of PNG over GIF is typically the
filesize of a PNG is about 20% smaller then the same GIF image.
Finally, as discussed in the PNG overview above, GIF has patent
restrictions with it's use.
What about TIFF?
The TIFF image format has been around for a long time, and will likely
be around for quite a while more. The TIFF format was the
cross-platform image format by choice until PNG was introduced, and
according to some still is. TIFF has been the most popular 24 bit image
format for print collateral as, in addition to the bitmap image data,
it can also store a numerous amount of various ancillary data, such as
Photoshop layers, alpha channels, printing profiles, color profiles,
etc. This tends to increas the file size some, but because print
collateral require high resolution bitmap image files to produce
satisfactory print quality, TIFF images are generally tote a very large
file size regardless. Until PNG, was the only standard lossless
compressed format. The standard 24 Bit PNG functionally is very similar
in function to a LZW compressed TIFF. The TIFF format is able to store
multiple images in one file. This is commonly used for FAX images.
PNG's do not have this capability. The TIFF format remains to be
popular, but there are few reasons to use it for photograph archival
with the added benefits of PNG.
What about JPEG?
Unlike PNG, JPEG uses a lossy compression routine. Lossy compression
means that the image loses quality and information each time it is
saved. Because JPEG uses lossy compression, the filesize is almost
always smaller then a PNG, especially for photographic images. Care
must be taken when working with JPEG images as each time a JPEG is
re-saved, more and more compression artifacts are introduced. Since PNG
uses lossless compression it's an ideal format ideal for archival
purposes, and for editing before saving a final version as a JPEG. JPEG
is the most common image format used on the web, and will continue to
be. Most photographic have commonly been saved as JPEG as opposed to
PNG
for viewing on the web as the filesize will be much smaller. However
with the proliferation of broadband connections, the added
functionality benefits of PNG images vs Jpeg images will see a trend
usage of PNG images. As the bandwidth restricted dial-up connection
gradually becomes obsolete and the broadband connection becomes the
standard, the image and media files sizes used will be relaxed, almost
certainly positioning the PNG to replace the Jpeg.
