I am using Libre Office Version: 126.96.36.199
Build ID: 00(Build:2)
CPU threads: 2; OS: Linux 4.15; USample-raster-OCRmypdf-pdf.odfI render: default; VCL: gtk3
Locale: en-IN (en_IN); UI: en-US
Ubuntu package version: 1:7.0.1_rc2-0ubuntu0.18.04.1
I noted that whenever I open a pdf file made of scanned image + OCR in Libre Office Draw for editing the last most text on every page is visible above the image. This cause lot of problem if I am working with 100s of pages. I have to select image on every page and move it to front.
Note: I used ocrmypdf to OCR those documents. if it is important.
Here are three files
1st “Sample-raster-OCRmypdf.pdf” is raster pdf containing ocr text after doing ocrmypdf. File link below in Edit3.
2nd “Sample-raster-OCRmypdf.odg” exported resultant file after opening above same file in Libre Office Draw. The last text on page visible to front as soon as i open file “Sample-raster-OCRmypdf.pdf” in Libre Office Draw.Sample-raster-OCRmypdf.odg
3rd file “Sample-raster-OCRmypdf-libreofficedraw.pdf” after exporting from Libre Office Draw. File link below in Edit3.
i converted the raster pdf file with ocr to PDF v. 1.4 using gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4. But still on opening resultant pdf file in Libre Office Draw no change.
Loading .pdf file with fake extension -pdf.odf. please change after downloading file.
Now I may tell that both above files images were edited with GIMP then exported >> to pdf and then >> OCR.
I scanned this file as pdfScanned-OCR-pdf.odf. did not opened this file in GIMP and created it by directly running OCR. When I opened this file in Libre Office Draw there was no flaw.
I may further tell that I downloaded a scanned pdf file with OCR scanned with Cannon scanner. When I opened that pdf file with Libre Office Draw all the text was at front and image at back. I can not share file link being third party.
So problem is different with different files and softwares.
