Bug ID: 148028
Summary: export creates huge pdf size, by about factor 100: 10
MB instead of 100 kB.
Product: LibreOffice
Version: 7.2.5.2 release
Hardware: x86 (IA32)
OS: macOS (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]
Reporter: [email protected]
Description:
When I export from LibreOffice writer, the file size is 12 MB for a tiny file
with 4 pages of size A6,
I checked and compressed the pdf file with wecompress.com. It confirmed that
the 13 images were 102 kB only, the two fonts where 32 kB. Wecompress was able
to reduce the pdf file to 105 kB. But it failed to report about the other
stuff.
Export as PDF shrinked the images to 150 dpi resolution.
When I do not use the export as PDF, but print to a PDF file, the result used
19 MB instead.
No background colors, no patters, standard fonts, but a special text color.
Steps to Reproduce:
1. create a. .ods file
2. Export as... PDF
3. Reduce Image Resolution to 150 dpi
Actual Results:
Size: 11 991 482 bytes (12 MB on disk)
PDF-Version: 1.6
Pages: 4
Resolution: 419 × 297
Expected Results:
File size after compression with wecomoress.com: 110 193 bytes (111 KB on disk)
That's about the size I would have expected, but not 100 times of that.
Reproducible: Always
User Profile Reset: No
Additional Info:
The original .odt is 4.7 MB in size, with large uncompressed images.
It does contain a bitmap file from LO Draw - that's a problem of its own, since
draw contained an inported png with an overlay of draw elements: circels,
arrows and text. I could copy this combined drawing to Writer, but I could not
resize it their. The png part shrinked, but the draw elements kept their size.
