I know Mozilla PDF.js is used only for PDF viewer purpose. By using some open source codes like (annotations) I have created some highlight, underline and strikeout features over PDF viewer.
Now I want to implement the free text and callout features to be added on top of it. Also while performing an annotation I want to retrieve the co-ordinates of PDF where the annotation is added.
Any help would be appreciated.
I am developing the app like ibooks by reference,in that the pdf is not enabling the menu i.e while I long tap the pdf it not showing Menu like copy , define.
How can I work in menu? Help me.
The linked solution simply does not implement text selection or glyph coordinate extraction/conversion. You need to parse the PDF page content stream and track glyphs on the page. CGPDFOperatorTable can be a starting point, however I suggest reading the PDF spec and getting familiar with the multiple transformation matrix states that a page can have - it's quite tricky to get right. You also need to embed various CMaps (character maps) so that all fonts can be correctly parsed. It took me more than a year to get a reliable text extraction for >99% of all PDF documents. If you want to save this time, you can check out the commercial PDF SDK I am working - google for PSPDFKit. We support iOS and Android.
How to play with the PDF document in ios?
I have to perform some operations on the PDF document like - read the PDF document, Adding annotations to PDF, making note on PDF, Search text in PDF, highlighting the text in PDF document.
How this can be achieved? Can anyone please suggest me a sdk or tutorial? (Except PDFKitten...)
I know it is old question but since iOS11 you can use PDFKit.
The goal is to be able to insert images with text when sharing text into an SMS Message from the App as well as in e-mails. Like it is in the picture below. When I try to share images with the UIActivityViewController the images appear on the next line and not next to the text. Is it possible to embed images in text and e-mail like the built in Emoji text?
The contents of text messages are just that, text (that is, a sequence of Unicode code points.) The emoji images you see in the screenshot come from a system font installed on all iOS devices, and are represented in the text as unicode code points, just like the other regular letters in the same message.
If you want to embed custom images into text fields in your app, you can create a custom font that includes the desired graphics (for some code points in the Unicode private use area,) include the font in your app as an asset, configure your text fields to use that font, and then provide some UI for the user to type those code points in.
But remember that this will only work on devices that have your custom font installed, and in apps that choose to use that custom font to display the text — so essentially only in your own app. So for example if you'd send the text in an email or iMessage/SMS to another device, your custom graphics would not work unless a) the receiving device has your custom font installed system-wide, and b) the app displaying the text resolves the Unicode private use area code points you chose to use for your images to this custom font of yours.
If you only want to embed images into text fields within your own app, on iOS 7 and later you can use the text attachments feature that TextKit supports.
Does iOS provide any control upon the attributes of the text present on a PDF,i.e can we change the background color of the text present on the pdf, say for when a audio sync is in progress? I guess CGPDF does not provide much to control or rather extract the content information of a PDF page. Any other library that can help? Thanks !
