Advanced image processing capabilities
Document image processing
Professional document cleanup filters optimized for scanned documents and digital images. Automatic deskew corrects rotation up to 15 degrees, multilevel noise removal eliminates speckles and artifacts, and blank page detection streamlines workflows. Enhance characters for better OCR accuracy, remove punch holes and borders, and apply bitonal cleanup for smaller file sizes. Essential for high-volume scanning and document digitization.
Image processing and filters
More than 50 professional image filters for enhancement, artistic effects, and technical processing. Apply blur (Gaussian, standard), sharpen (standard, intensified, unsharp mask), edge detection (Sobel, Prewitt), and artistic effects (sepia, emboss, pixelize, swirl). Adjust color depth from 1-bit to 128-bit, convert color modes, and apply morphological operations. Region of interest (ROI) support targets specific image areas without affecting the entire document.
