Image compression solves the problem by reducing the amount of data required to represent an image. The uncompressed image data requires a large storage capacity and transmission bandwidth. The objective of the image compression algorithms is to reduce the amount of data required by an image with ...
compressionFormat: is the compression type of image checkProperties Method Format checkProperties RETURN BOOLEAN; Description Verifies that the properties stored in attributes of the image object match the properties of the image stored in the BLOB or BFILE. This method should not be used for foreign...
An image from a PDF document can be compressed in a number of different ways. Here are the possible values that you can pass to compression-related parameters: 1 BmpBwUncompressed 2 BmpGrayUncompressed 3 BmpColorUncompressed 4 DcxBwPackbits 5 DcxGrayPackbits 6 DcxColorPackbits 7 JpegGrayJfif ...
JPEGs might be the most common file type you run across on the web, and more than likely the kind of image that is in your company's MS Word version of its letterhead. JPEGs are known for their "lossy" compression, meaning that the quality of the image decreases as the file size de...
Types of compression algorithms There are generally two stages in an image compressor, a lossy phase, and lossless phase.Lossycompression algorithms will modify the source stream such that you lose information that cannot be restored upon decompression.Most lossy algorithms in image compression take adv...
Image with Fine Detail (Less Effective JPEG Compression) Image without Fine Detail (More Effective JPEG Compression) It is also helpful to get a visual intuition for how varying degrees of compression impact the quality of your image. At 100%, you will barely notice any difference between the ...
edited just like documents, so there is an overlap here, unlike the document formats these are specifically for image files. Unlike document file formats, there is a bit more differentiation between them, however, a lot still depends on the software you are using and the purpose of the file...
fileFormat: the file type or format in which the image data is stored (TIFF, JIFF, and so forth.). contentFormat: the type of image (monochrome and so forth). compressionFormat: the compression algorithm used on the image data. mimeType: the MIME type information.8.1...

image because the compressor throws out a vast amount of information to reduce the file size. It's better to try for a quality value of 8 or higher. JPEG is not suitable for images with text, large blocks of color, or simple shapes because crisp lines will blur, and colors can shift....
