Parameters

page

1-bit ImGearPage object to apply the method to.

minWidth

Specifies the minimum width for areas that you would like to invert.

minHeight

Specifies the minimum height for areas that you would like to invert. For example, if you set minX = 60 and minY = 20, ImageGear will only invert sections of white text on black background that have a minimum width of 60 pixels and a minimum height of 20 pixels.

minThickness

Specifies the minimum "thickness" of spaces that fall between sections of text that will be inverted. This minimum value indicates those sections of text to be treated as one section based on how close they are to one another. As an example, let's say you have three adjacent sections of white text on black backgrounds that contain the words, "There," "is," and "hope." If "There" and "hope" meet your minimum size requirements they will be inverted. If "is" is below your minimum size requirements, and you have not set minT, "is" will note be inverted, resulting in "There" and "hope" looking normal, while "is" remains white text on black background. To prevent this (if desired), you would need to set minT to a value small enough to include the spaces before and after the word "is." This way, all the words would be treated as one section and inverted together.

minLetterSize

Specifies the minimum size of the white letters to be inverted.

maxLetterSize

Specifies the maximum size of the white letters to be inverted.

maxBorderSize

Specifies the size of the maximum border around the letter that will be inverted along with the letter cell. For example, if width and height of the letter cell are 20 and 30 respectively and maxBorder = 10, then the width and the height of the rectangle that will be inverted are 40 (10+20+10) and 50 (10+30+10) respectively. Please be careful when setting this parameter. If it is very large, it is possible that incorrect image areas will be inverted.

This method scans your entire image and makes adjustments to all areas of white text on black that fall within the scope of your settings.
