TifIMG 16/32 features

TifIMG 16 and 32 bit Delphi components provide for reading of numerous image formats such as TIFF, BMP, PCX, DCX, JPEG, TGA, WMF, WPG and the new PNG graphics format. It is principally designed for developers using TIFF files, and it encapsulates most of the work in building image viewer, conversion and filing systems. The component comes with a complete demo illustrating flip, rotate, zoom and pan, scaling, brightness and contrast, dithering, text annotation, cropping. Automatic color reduction is provided for JPEG images, allowing viewing of 24 bit color on a 256 color system. pan and floating magnifying glass functions allow great flexibility along with ease of use.

Sample programs are available illustrating batch conversion from one format to another, creation of thumbnails, reading and storing TIFF files in a paradox BLOB, etc.

New features in version 2.3

freeform zoom by rubberband box
brightness and contrast control
grayscale/halftone from color images
skew image by x Pixels X-axis or Y-axis
rotate image by one degree increments
capture other windows on the desktop into TifIMG (good for documentation and help files)

See Kent's article on TIFF Images for a description of what the image format is and does, and issues associated with using it, such as resolution, compression scheme, and contrast.

Multiple versions available
Versions for Delphi 2-7 and codegear Delphi2005-Delphi2007

Read many formats automatically
TifIMG will not only load the supported image based on its extension; for TIFF images you may specify an alternate extension (such as ".001" or ".PIM") and TifIMG will treat that as a TIFF file as well. TifIMG automatically decodes the image using whatever compression format the TIFF header specifies, including G4, G32D, G31D, packbits, uncompressed, etc.

Many image manipulation features
These include rotation, scaling, panning, zooming, text annotation, cropping, saving in other formats, brightness and contrast control, color reduction, skewing, rotating by degree increments, and more.

Example code
In addition to the extensive demo program, many other source code examples are available to illustrate storage of images in database BLOBs, batch conversion programs, image comparison programs, barcode reading, and more.

No royalties
TifIMG is royalty free.

Support for odd images
An add-on to TifIMG is CCITT, an extension which will allow you to read raw CCITT compression formats without a TIFF header, if you know the image dimensions and compression type. This allows the reading of many proprietary fax and document imaging formats with a little experimentation. Some knowledge of TIFF and image compression concepts is helpful in using this component. Readers for WinFax and BITFAX images are supplied with the CCITT add-in.
