I'm trying to control paging of a PDF file in
doc-view mode. Say we have the following snippet
(let ((origin-frame (window-frame))) (with-selected-frame (make-frame-command) (let ((pdf-buffer (find-file "./test.pdf"))) (set-window-buffer (get-buffer-window) pdf-buffer) (select-frame-set-input-focus origin-frame) (with-current-buffer pdf-buffer (doc-view-goto-page 5)))))
we make a new frame the display the pdf buffer then go back to our origin frame and try to scroll the pdf buffer to page
5 in the origin buffer.
eval the snippet, we can see the pdf buffer is actually displaying the content page
5, while the mode line says
P1/12 DocView.(Note that the first time you open the pdf it may take some time to convert the pdf and causes the snippet fail) Switch to the pdf buffer and press
n which calls
doc-view-next-page, we can see the buffer goes to page
That is to say, the buffer is not really went to page
5 just now but its 'content display' did. Using
doc-view-goto-page in the pdf buffer will not have this problem as the modeling says
P5/12 DocView after evaluation.
How to fix this? Is
with-current-buffer not the way to go here? Thanks in advance!
