Uneven lighting or shadows
- • The paper tone is estimated from the paper right around the word.
- • The erased area is filled to match a shaded or bright patch, not a flat white.
How vFlat Scan scans
- • vFlat flattens curved book pages, which leaves straighter lines to edit.
- • Phone scanners photograph the page, straighten and crop it, and save the image into a PDF.
- • Photos carry perspective, uneven light and JPEG compression, and some apps add a hidden OCR text layer.
- • Camera foreshortening is fitted as a horizontal scale on each line, and the paper grain around the word is kept, so the new word sits in the photo like the old one.
Questions people ask
+What if a word cannot be changed invisibly?
You get the exact reason, such as a stamp in the way or a font that could not be identified, instead of a smudged page.
+Do I need to convert the scan to Word first?
No. MythosPDF edits the scanned page itself. There is no conversion, so the page keeps its look.
