What is the reocmmended parameters to use to convert PDF to image in order to get best result from tesseract

[fady taher]

Am trying to perform OCR on some PDFs, I use image magic to convert PDF to image yet, when I apply tesseract some of the values are miss-interpreted.

on the other hand, converting the same PDF using online tools produces images which outputs correct values when applying tesseract.

Is there any recommeneded params to use while converting to image ?

the below are the ones am currently using

pdfConvDensity = "-density"

densityVal = "300"

setO, setOCoSp, setOCo, setOSeperate, setOAvg = "-set", "colorspace", "Gray", "-separate", "-average"

quality = '-quality'

qualityVal = '100'

depth = '-depth'

depthVal = '2'

antialias = '-antialias'
