Edit Text and Image Properties ​

ComPDFKit offers various methods to modify text and image attributes.

Edit Text Properties ​

ComPDFKit supports modifying text properties, such as text font size, name, color, alignment, italics, bold, transparency, etc.

This example shows how to set text to 12pt, red, and bold:

swift
pdfView.setEditingSelectionFontSize(12.0)
pdfView.setEditingSelectionFontColor(.red)
pdfView.setCurrentSelectionIsBold(true)
objective-c
[pdfView setEditingSelectionFontSize:12.0];
[pdfView setEditingSelectionFontColor:[CPDFKitPlatformColor redColor]];
[pdfView setCurrentSelectionIsBold:YES];

Below is the example code for creating and removing underlines and strikethroughs for text:

swift
//  creating underlines and strikethroughs for text
pdfView?.setCurrentSelectionShowUnderline(true, with: editingArea as? CPDFEditTextArea)
pdfView?.setCurrentSelectionShowStrikeout(true, with: editingArea as? CPDFEditTextArea)

//  removing underlines and strikethroughs for text
pdfView?.setCurrentSelectionShowUnderline(false, with: editingArea as? CPDFEditTextArea)
pdfView?.setCurrentSelectionShowStrikeout(false, with: editingArea as? CPDFEditTextArea)
objective-c
//  creating underlines and strikethroughs for text
[pdfView setCurrentSelectionShowUnderline:YES withTextArea:(CPDFEditTextArea *)editingArea];
[pdfView setCurrentSelectionShowStrikeout:YES withTextArea:(CPDFEditTextArea *)editingArea];

//  removing underlines and strikethroughs for text
[pdfView setCurrentSelectionShowUnderline:NO withTextArea:(CPDFEditTextArea *)editingArea];
[pdfView setCurrentSelectionShowStrikeout:NO withTextArea:(CPDFEditTextArea *)editingArea];

Edit Image Properties ​

ComPDFKit supports modifying image properties, such as rotating, cropping, mirroring, and setting transparency.

This example shows how to rotate an image and set it to semi-transparent:

swift
pdfView.rotateEdit(pdfView.editingArea() as! CPDFEditImageArea, rotateAngle: 90)
/**
 * Set the image transparency.
 */
pdfView.setImageTransparencyEdit(pdfView.editingArea() as! CPDFEditImageArea, transparency: 0.5)
objective-c
[pdfView rotateEditArea:pdfView.editingArea rotateAngle:90];
/**
 * Set the image transparency.
 */
[pdfView setImageTransparencyEditArea:pdfView.editingArea transparency:0.5];
