How do I ensure temp files are deleted when closing ImageGear .NET?
All PDF objects are based on underlying low-level PDF objects that are not controlled by .NET resource manager and garbage collector. Because of this, each PDF object that is created from scratch should be explicitly disposed of using that object’s Dispose() method.
Also, any ImGearPDEContent object obtained from ImGearPDFPage should be released using the ImGearPDFPage.ReleaseContent() in all cases.
This should cause all temp files to be cleared when the application is closed.
How can I improve the performance and memory usage of scanning/recognition in Barcode Xpress?
Barcode Xpress supports a number of optimization settings that can improve your recognition performance, sometimes up to 40%, along with memory usage. The best way to optimize Barcode Xpress is to fine-tune the properties of the Reader class to be specific to your application’s requirements.

Finally, BarcodeXpress Professional edition does not impose a 40 page-per-minute limit on processing.
What quality should my images be for processing form data and recognition using FormSuite?
In all cases, you want to have your images as clear and as clean as possible. For any particular procedure, please consider the following:
OCR and ICR: Capture images in at least 300 DPI resolution. Ideally, working in black and white allows the objects of interest on your image to be better defined and recognized. Free the image form all noise as much as possible. As if a human were reading it, you want the text objects on the image to be as legible as possible. For ICR, ensure that the characters are printed (no cursive text, etc).
Barcode recognition: As with OCR and ICR, capture images in at least 300 DPI and working with black and white content can provide excellent results. Ensure that the bars in the barcodes are clearly defined on the image and are not malformed (for example, the barcodes should have the proper start and stop sequence, etc). Clear as much noise from the image as possible.
Forms matching and registration: As with the prior 2 items above, capture your documents in at least 300 DPI. Ensure that your resolution is consistent between your form templates and incoming batch images. Form templates should only contain data that is common to every image that is being processed (i.e. Form fields, the text that appears on the blank form itself, etc). The template should not have filled-in field information as this will affect the forms matching process.
The ISIS Xpress BasicCapabilities and AdvancedCapabilities samples demonstrate a number of different ways to acquire images and save a batch of them to file, but how can I get a single image as soon as it gets acquired by the scanner?
During the ISIS Xpress Scanned() event, you can get the currently acquired page via the ISISXpress.Output property (i.e., – ISISXpress.Output.TransferTo() or ISISXpress.Output.ToHdib()).
