TBlowupPanel It's an addon component for Envision Image Library. It displays a small part of the pixel configuration around the cursor in the main window in a TImageScrollBox component. The content of the blowup window changes as the cursor is moved around the document. The size of each pixel in the window is enlarged to ease the operation of fine tuning the cursor to a specific point and to see image details as with a magnify lens. You can set the zoom factor of blowup window from 1x to 100x

TServerCountQuery It's a discendent of standard TQuery. It allows to fix the (very) slow method to count result records used in the standard query component: fetch each record from the server and store it on the client, increasing a counter... If you use local DBMS as Paradox or dBase you don't are afflicted by poor performances, but if you use DBMS server as MS SQL Server or Oracle, each time your code call the RecordCount method you assist to HD light flashing, network traffic increasing and a very long response time. More results are in the query recordset, more problems you have... More time you use the RecordCount method on the same query, more time you have the problem... TServerCountQuery solve the problem, asking directly to the DBMS the number of records retrieved: fast, easy and clear. You can use this component as a standard TQuery component, all the work is done in background and if some error occours, will be fired an OnCountError event and the standard RecordCount method will be called. You can access too to the LastCountSQL string propery to see the SQL statemant used to retrieve the record count in the current query.

TDeskewTransform It's an addon component for Envision Image Library. The component allows to auto detect and correct the skew of an image. The skew is the little inclination who usually haves a scanned or faxed page. To deskew an image means to estimate and fix this imperfection. Correcting the skew allows to: * Have lower file size using CCITT-G3, CCITT-G4, Rle and PackBits compression algo * Improve results using OCR and ICR products * Obtain a perfect image at first shot, with no need to re-scan o re-fax the original The component is fast and accurate: on a PIII 600Mhz detect the skew of a 300 DPI A4 size image in less then one second with a 0.1 degree accuracy !

TScaleToGrayTransform It's an addon component for Envision Image Library. The component allows to resize a monochrome image using scale-to-gray technology. The scale-to-gray technology allows to preserve image details at low zoom factors using different gray levels. You can specify the gray shades from 4 to 256 and set the zoom percent factor from 1% to 100%. With this component you can display a black and white image in an enhanced mode, making it easier to view. Displayng the same image using standard antialiasing and hi quality scale-to-gray you can see the difference !

TOverviewPanel It's an addon component for Envision Image Library. It shows a complete overview of the image contained in the main windows in a TImageScrollBox component. The purpose of this extra windows is to display the entire document while only a part is visible in the main window. You will notice a small frame of customizable color in the overview window when viewing an image. This frame corresponds to the area visible in the main window. When panning around the document, the square moves orrespondingly. When the zoom factor in the main window is changed, the size changes, enclosing the new area selected for viewing. When moving the cursor over this window, if you click the mouse button, the colored frame follows the pointing hand to the new position and updates the contents in the main window. The colored frame can also be dragged around by holding down the left mouse button while it is moved.
