Public API Changes

ITextSearchOptions interface has been added

The new interface, ITextSearchOptions, represents options that can be used to search for text in a Presentation, Slide or TextFrame.

Example:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as presentation:
    text_search_options = slides.TextSearchOptions()
    text_search_options.whole_words_only = True

    presentation.replace_text("the", "***", text_search_options, None)
    presentation.save("pres-out.pptx", slides.export.SaveFormat.PPTX)

ITextFrame.highlight_text() and ITextFrame.highlight_regex() methods have been added

New methods hightlight_text and highlight_regex have been added to the ITextFrame interface and the TextFrame class.

The following code sample shows how to highlight text in a TextFrame:

import aspose.slides as slides
import aspose.pydrawing as drawing

with slides.Presentation("pres.pptx") as presentation:
    # highlighting all words 'important'
    presentation.slides[0].shapes[0].text_frame.highlight_text("important", drawing.Color.light_blue)

    text_search_options = slides.TextSearchOptions()
    text_search_options.whole_words_only = True

    # highlighting all separate 'the' occurrences
    presentation.slides[0].shapes[0].text_frame.highlight_text("the", drawing.Color.violet, text_search_options, None)

    presentation.save("pres-out2.pptx", slides.export.SaveFormat.PPTX)

The following code sample shows how to highlight text using regular expression in a TextFrame:

import aspose.slides as slides
import aspose.pydrawing as drawing

with slides.Presentation("pres.pptx") as presentation:
    # highlighting all words with 10 or more characters
    presentation.slides[0].shapes[0].text_frame.highlight_regex(r"\b[^\s]{10,}\b", drawing.Color.blue)

    presentation.save("SomePresentation-out.pptx", slides.export.SaveFormat.PPTX)

ITextFrame.replace_text() and ITextFrame.replace_regex() methods have been added

New methods replace_text and replace_regex have been added to the ITextFrame interface and the TextFrame class.

The following code sample shows how to replace a specified string with another specified string:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as presentation:
    text_search_options = slides.TextSearchOptions()
    text_search_options.whole_words_only = True

    presentation.slides[0].shapes[0].text_frame.replace_text("the", "***", text_search_options, None)
    presentation.save("SomePresentation-out2.pptx", slides.export.SaveFormat.PPTX)

The following code sample shows how to replace text using regular expression:

import aspose.slides as slides

with slides.Presentation("pres.pptx") as presentation:
    # Replace all words with 5 or more characters with '***'
    presentation.slides[0].shapes[0].text_frame.replace_regex(r"\b[^\s]{5,}\b", "***")

    presentation.save("SomePresentation-out.pptx", slides.export.SaveFormat.PPTX)

    text_search_options.whole_words_only = True

    # highlighting all separate 'the' occurrences
    presentation.highlight_text("the", drawing.Color.violet, text_search_options, None)

    # highlight all 'abi' character sequences
    presentation.highlight_text("abi", drawing.Color.red)

    presentation.save("pres-out.pptx", slides.export.SaveFormat.PPTX)
