TIFF (Part 2)


Disadvantages of TIFF Images

  • Raster Image Format
    TIFF is a raster image file format which means that it is made up of small bits which may distort the image quality if resized.
    The security level of this format is not very sophisticated. User can set the security for whole file but cannot set security for individual file components.
    TIFF image format is not able to embed or attach other file types with it unlike other format types such as PDF.

  • Not suitable for Printing Purposes
As said earlier, image resize might distort the image quality which result in poor print quality hence these images are not suitable in printing industry.
  • Security
  • Cannot Attach other file types

Conclusion

TIFF file format should be used in the scenarios where we need to edit our image and keep the image size small. In cases where we need high quality images with sophisticated security and embedding features, we should prefer latest file format types such as PDF. (read TIFF vs PDF )

TIFF (Tagged Image File Format)


The was an article Tiff vs PDF some time ago. This one is more detail about TIFF
TIFF stands for Tagged Image File Format. TIFF is one of the most widely used image formats.TIFF is particularly popular in image editing industry, graphic design artists, professional and novice photographers owing to the ability of being easily edited. TIFF is a raster or bit map image format and the TIFF files end with extensions .tiff or .tif.

History

In the early 1980s, vendors of the desktop scanners had their own scanning format and there was no standard format for scanning images. Keeping in view this requirement, efforts were made to develop a common scanning format for desktop scanners. It was due to this reason TIFF image format was developed in the mid of 1980s.
At that time desktop scanners used to scan documents in binary format. The scanned pixel could have only 0 or 1 as their values; hence the initial TIFF was in the binary form. With the passage of time, technology evolved and scanners became more sophisticated and powerful and started to accommodate grey scale images as well. Finally color images were also stored in TIFF format. Today TIFF is capable of storing high depth color images of several types. No major update to the TIFF file format has been released after 1992.
Initially, a company named Aldus created TIFF file formats and owned all its copyright. In the year 2009, Aldus was acquired by Acrobat systems and currently it holds all the rights and ownership of TIFF format.

Advantages of TIFF Images

Following are some of the reasons why TIFF images should be used for storing images.
  • Compression
    TIFF is a lossless compression format which means that it do not lost its quality if the image if dot per pixel value is modified. This capability of TIFF images make them portable to almost every hardware and software.
    TIFF files can be easily edited and modified. It is due to this reason that this image type is very famous amongst the publishing industry and professional photographers who need to edit their images often times.
  • Easily Edited

.NET FRAME WORK


.NET frame work is a multipurpose software application development framework developed by Microsoft. It provides uniform set of tools and features which can be used to develop variety of applications including desktop, web based and mobile applications. The best thing about .NET framework is that you don’t need to learn much about application development techniques once you have basic understanding of the frame.

There are two basic components of .NET framework.

Common Language Runtime

Common language runtime is a .NET runtime framework which is able to run all the .NET supported programming language. .NET compiler do not directly compiles source code to machined code; rather it converts into Microsoft Intermediate Language which also called managed code. Managed codes of all the .NET languages are same such as C#, VB and J#.  Hence, the modules developed in one language can be integrated with each other.

Framework Class Libraries

Framework Class Libraries are set of already build modules containing built in capabilities which we can reuse and modify according to our needs. FCL immensely reduces the amount of code required to develop an application. It provides built in frameworks for developing web applications, networking, database capabilities, algorithms and designs etc.

History

During development phase in the late 90s, .NET framework was given the name “Next Generation Windows services” short hand notation was NGWS. Microsoft initially released the beta version of first .NET framework in year 2000. Basic purpose of developing was to compete with Sun’s JAVA which was at that time, sole giant in the software development industry. The first version of .NET framework was developed in the year 2002 and it was given the name .NET 1.0. The resource is here.
There are a lot of source samples with  .NET Framework at ByteScout web-site, for example How to generate barcode image in Visual Basic 6 and save barcode in EMF

PROS and CONS of JPEG Image Compression


JPEG format is one of the most commonly used formats for storing images and photographs. JPEG is an abbreviation of Joint Photographic Expert Group. There are two major categories of JPEG format, one is used by digital cameras to capture and store photographs, called JPEG/Exif format. The other category of JPEG format is JPEG/JFIF format which is mostly used for image transferring and image storing.

Advantages of JPEG Image Format
There are several advantages of JPEG image format.
  • JPEG format has been in use since long time and is extremely portable.
  • JPEG format is compatible with almost every image processing application.
  • JPEG format is compatible with most of the hardware devices e.g printers etc; therefore it is very easy to print the images in JPEG format.
  • JPEG format can be used to store high resolution fast moving images which would be blur in other image formats because owing to their small size, JPEG images can be stored quickly from a camera to storage device.
  • Size of JPEG images can be reduced and compressed which makes this file format suitable for transferring images over the internet because it consumes less bandwidth. A JPEG image can be compressed down to 5% of its original size.
There are plenty of advantages of JPEG Image format; however there are certain disadvantages and drawbacks of these images as well which are of major concern for the photographers and computer scientist which cannot be neglected.
Disadvantages of JPEG Image Format
  • JPEG compression technique is a lossy compression. Lossy compression means that after image is compressed in JPEG format, it loses certain actual contents of the image.
  • Quality of Image is reduced after JPEG compression owing to the loss of actual content of the image.
  • JPEG image compression is not suitable for images with sharp edges and lines. JPEG image format is not capable of handling animated graphic images.
  • JPEG images do not support layered images. Graphic designer need to work on layered images in order to manipulate and edit graphic images which is not possible with JPEG Images.
  • Only 8 bit images are supported by JPEG format. On the other hand, modern high resolution digital cameras support 10, 12, 14 or 16 bit images. If these images are stored in JPEG format, extra information is discarded, resulting in decreased image quality.
JPEG Compression for Barcodes and Facial Images
Barcode in JPEG format reading by BarCode Reader
As discussed, JPEG compression results in loss of data. JPEG compression should not be used to store barcodes. Storing barcodes in JPEG format can result in distorted barcode pattern and can add noise to the barcode image which makes it very difficult for barcode scanners to decode the actual contents of the barcode. Similarly JPEG compression is not suitable for storing facial. It can make it difficult for face recognition softwares to recognize facial images compressed with JPEG compression technique.
Conclusion
It can be concluded from aforementioned facts that JPEG images should only be used in case you want small sized, portable images with smooth edges and color contrast, irrespective of the image quality; however if you want high resolution editable images with sharp contrast, using JPEG image is not a good choice and other image formats such PNG and GIF should be considered which are based on lossless compression algorithms.
