V Stuart Foote <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] Blocks| |61914 --- Comment #1 from V Stuart Foote <[email protected]> --- The Thumbnail rendering of the Most Recently Used file history shown in the Start Center are PNG previews recorded to user profile when the document was last saved. The previews are not intended to be zoomed or to contain high fidelity rendering of the page of the document used for the thumbnail. They are just a visual reference. Since there is no intent for high resolution there is no need to scale or zoom in tothem while the start center is visible--they're suitable to task as is. So IMHO => WF as zoom and resize of the SC would be a lot of effort for limited function. =-extract binary64 encoded image used for thumbnail on SC-= But I understand your plight, and as it happens we don't use the full resolution of the PNG preview image recorded to profile--it gets scaled down a bit (depending on module and view port). So if you want to see the detail in the actual thumbnail it can be extracted from profile. The document thumbnail is held a base64 encoded binary file in the LibreOffice user profile-- normally in %APPDATA%\LibreOffice\4, i.e. C:\Users\<yourusername>\AppData\Roaming\LibreOffice\4\user\registrymodifications.xcu Extraction is pretty simple, and can be done locally with no network connection. Open the .xcu file in a text editor (gvim, notepad++, even Microsoft's notepad) Search or scroll to locate the "Thumbnail" stanza from the HistoryInfo for document. Copy the text between the <value> and </value> markups. Paste as text into a new text editor file (not Writer as LO should be closed), name it "extractThumbnail.b64" or such Open a PS or CMD prompt, to run the conversion with this: "certutil -decode extractThumbnail.b64 thumbnail.png" You should get a -decode command completed successfully and have the image to review. Open the resulting PNG image (in a web browser, or image viewer). The image will show as much detail as is available in the thumbnail--but that will vary on the type of document and the actual size of its canvas as the preview was rendered on its last save.
