Free method or (as suggested by Joseph) FreeAndNil. Since the TDelphiTwain appears to be a component you are creating in code, I would recommend passing in nil for the constructor and calling the. Showmessage('Error Scanning Packing List.') Twain.OnSourceSetupFileXfer := TwainSourceSetupFileXfer

Twain.OnSourceFileTransfer := TwainSourceFileTransfer Twain.OnTwainAcquire := TwainAcquireHandler //manually set the event handler Has anyone had similar issues, or have some suggestions? After an hour or so of repetitive scans, the image scanned is zoomed in approxamately 10 times, and just the upper-left square inch is stored.After each scan a little more memory is being held onto.#include 'stdafx.h'#include 'recoio.Using the DelphiTwain files from and am getting some weird behavior.

Here is the source code in Microsoft Visual C++ of a sample application using the imaging library: If you wish to test this library you can download the demo application (400 KB) that allows you to open and display your tif images: please give us your feedback and your comments after the test! This library can be very useful with all other libraries developed by Recogniform Technologies when you have to supply the DIB (Device Independent Bitmap) handle.

Two functions allow you to get and release the DC on the images, using them as normal draw surfaces! Also you can import/export images as standard bitmaps ( HBITAMP and HPALETTE). Image editing is very flexible because you can use all graphic Windows API (GDI) on your images, as writing on a standard device context.

For each image you have direct access to the DIB memory handle, so there's no need to deal with proprietary memory formats!

You can also extract sub-images as required by ICR/OCR or other tools that only need the field to process and not the full image. Image processing funcionality allows you to invert, rotate by 90/180/270 degrees, flip and mirror images. Stretching to fit images to display surface is supported, too. You can set the zoom factor choosing values ranging from 1% to 1000%. Image visualization can be done using a sophisticated Scale-To-Gray algorithm that improves visualization of large images in small screen areas.

Moreover, the last release of Recogniform Imaging library allows you to read/write PDF multi-page files, without installing Acrobat ReaderВ® on your PC! For JPEG files you can also set the quality factor, in order to balance the quality vs compression ratio.

Multipage TIFF files are also supported available compression schema are: uncompressed, ccitt-g4, ccitt-g3, packbits, deflate, jpeg and lzw ( requires Unisys license in some countries). You can load and save images from/to BMP, JPG and TIF files. The most common file formats are supported as well as several compression standards. Image loading and saving feature allows to read/write images from/to disk. Also a simple callback method allows you to scan multiple images in one step when automatic document feeder or duplex are enabled! When scanning without user interface, you can set color depth, resolution, size, brightness, contrast and enable or disable adf and duplex mode. Images scanning is supported by scanner's standard TWAIN drivers, with or without user interface.
