One can use easy-ocr in two ways. first one is to scan and produce text from the program itself and second one is to produce the text from the folder containing image. in order to start scanning using the program, please follow the steps given below.
for the sake of portability, we have not assigned any shortcuts. however, assigning shortcuts will make the programme very easy to use.
Go to easy-ocr(or other) menu and select settings and enter. then the scanner will be detected and you will have to set the duration between the repeated scanning, resolution, brightness or threshold, engines, scan area and language. Once you have completed the settings, the values you have entered will be read aloud, And also settings will be kept until make any further changes in the settings.
Now go to easy-ocr menu and select either scan or scan with full auto rotation. in the scan mode, the programme will ask for the file name. after entering the filename select OK and then you have to select the rotation mode. if you are sure of the angle in witch you have kept the book , select the manual mode and check the degree of rotation. if you are not sure of the angle, please select the automatic mode and scanning will be done in order to determine the rotation needed. then the rotation selected will be kept and you have to start from the first page itself.be careful not to change the angle kept in the beginning. after each scanning, the page number will be announced and after hearing one, you can press add button and start reading along with scanning. if you are totally unaware of the angle in witch the papers are kept, you can select full auto rotation mode. here also after hearing one, you can start reading by pressing add button. the text produced by these two modes will be saved in documents unless you change the directory. if you are in need of continuing the file, you can select the same file and the text will be appended to the old one.
now one can convert images saved in the folders in to text by using the folder option.if you are not in a position to use the easy-ocr, you can use any scanning program to produce the images. this option will support png, jpeg, jpg, tiff, tif, pnm, pdf formats. select the folder option and enter. now you will have to select the folder, format of the image,rotation mode, saving folder.etc. if you are sure of the angle in witch the images are kept you can select manual mode, and if you are not sure of the angle, you can select automatic mode. in the automatic mode,all the images will be converted, as in the angle of the first image. in the full auto rotation mode, we are not to be concerned of the angles.
there is facility for converting text in to wav files. just enter the audio conversion mode and select the folder containing the text to be converted and give the values in the window shone.
one can stop all scanning process by entering the stop scan.
