Set the parameters for saving the recognized text into a PDF file:
|Save Mode group|
|Text and pictures only||The recognized text is saved as text, and the pictures - as pictures.|
|Page image only||Only the image is saved.|
|Text over the page image||The entire image is saved as a picture. Text areas are saved as text over the picture.|
|Text under the page image||The entire image is saved as a picture. The recognized text is put under it. This option is useful if you export your text to document archives: the full page layout is retained and the full-text search is available if you save in this mode.|
|Retain text and background color||Set this option if you want the original background and
character color to be retained.
If the Text under the page image mode is on, text and background color is saved automatically.
|Replace uncertain words with image||If you save your document in the Only text and pictures or the Text over the page image modes, you may have uncertainly recognized words replaced with their images. To do it, set this option.|
|Font use mode||
|Type1 fonts (button)||Opens the Type 1 fonts settings dialog. The Type 1 fonts to set are serif, sans serif, and monospaced. These fonts are used for saving documents in a non-latin code page.|
|Reduce picture resolution to||
Sometimes you may want to reduce the image resolution. For example, PDF files are usually viewed in a browser, so there is no sense to save high-resolution pictures in such files. So, you may reduce the image resolution (so reducing the PDF file size) without actually loosing the visual image quality: enter the necessary resolution value in the Reduce picture resolution to field.
When you save an image in JPEG format, the so-called "quality loss" algorithm is used to compress the image, i.e. the compressing technology is bases on averaging the groups of pixels, so that a whole region is saved as a single number and not as a big number of numbers that describe each pixel. The value specified in the JPEG quality field allows to set the desired quality of the image. You may specify a value in the range 1 - 100 (the default is the average value of 50).
The higher the value you specify in this field, the higher will be the quality of the image you save. The size of the image is also affected by this value: the higher the value, the larger *jpg file you get. In order to tune the best proportion size/quality, try to save the image with different JPEG quality value, and then open them in an image viewing application.
