Handles the acquisition from scanners (devices) that are TWAIN compliant.
Selecting the desired scanner and acquiring an image is as easy as thinking
of it :-) No more troubles with DIBs conversion, and misterious message
handling!
Tested with HP, Epson and several other scanners over a wide range of computers.
Version | Release date | What's new | |
2.02 | 27 feb 1997 | - | extended the property BitDepth to hold bit depths up to 15bpp (bits per plane), thus being ready to acquire images up to 45 bits |
- | updated demo project to use new BitDepth features | ||
- | the demo project now checks for supported capabilities and disables controls accordingly | ||
- | done some minor changes to handle correctly some scanners that checked the TWAIN version supported by TEnhTwain | ||
- | the component version is now shown when right-clicking on it at design time | ||
2.01 | 14 feb 1997 | - | added new event OnRawData. When used, passes the handle of the newly acquired image without any further intervention, thus allowing the programmer to do whatever he likes with the data. Designed to work with 30 or more bit depths |
2.00 | 20 jan 1997 | - | the acquisition of an image can now be done without the dialog coming up |
- | added full support for Delphi 1 (16 bit) | ||
- | added function DeviceOnLine to know if a device is linked, switched on and operative | ||
- | added property BitDepth to set the number of bits per sample | ||
- | added property BDReduction to select how to reduce the number of bits per sample (halftones, diffusion, threshold,...) | ||
- | added property FastUI to speed up scanner's own modal dialog | ||
- | added property Indicators to disable status windows during acquisition | ||
- | added property PixelType to select what kind of image to acquire (B/W, Gray, RGB, Palette) | ||
- | added property Units to choose the units to be used | ||
- | added properties XRes and YRes to select the resolution | ||
- | added event OnLayout to choose which part of the image needs to be acquired | ||
1.01 | 23 dec 1996 | - | added a demo project |
1.00 | 20 nov 1996 | - | initial release |
There have been . Hope you enjoy here :-)
