margins

问题 I used pdftk to uncompress a PDF and then opened it as a text file. I want to edit the /MediaBox field, which is in my case /MediaBox [0 0 612 792] I would like to reduce the margins, for instance /MediaBox [100 0 512 792] Unfortunately it doesn't work. I can change the 0 into a 2 or a 9 but I cannot put 100 for instance. Any idea why? 回答1: use sed to replace any occurrence sed 's/MediaBox \[0 0 612 792*/MediaBox \[100 0 512 792]/g'<in.pdf >out.pdf or podofobox (inside podofo utils ) http:/

问题 I spent last few days trying to find a way to remove tiny margins from axes in a 3D plot. I tried ax.margins(0) and ax.autoscale_view('tight') and other approaches, but these small margins are still there. In particular, I don't like that the bar histograms are elevated, i.e., their bottom is not at the zero level -- see example image. In gnuplot, I would use "set xyplane at 0". In matplotlib, since there are margins on every axis on both sides, it would be great to be able to control each of

问题 I am trying to set the page margins on an excel spreadsheet that is being generated by open xml sdk. I am not opening an excel document that already exists, it is generated from scratch. I am using the PageMargins class but am not sure how to attach this instance to the worksheet. The SDK productivity tool gives this code: PageMargins pageMargins1 = worksheet.GetFirstChild<PageMargins>(); pageMargins1.Left = 0.45D; pageMargins1.Right = 0.45D; pageMargins1.Top = 0.5D; pageMargins1.Bottom = 0

问题 I'm trying to constrain a couple of views within a controller. I understand how to set spacing between views, and width/height for each view. I'm a little unsure about dynamic height and width, I'm assuming that it's the margin-locks duty to adjust the weight appropriately. Advice on this would be much appreciated. Anyways, I'm trying to set a "Trailing Space to: Superview" constraint, which automatically sets to -16. See photo: As you can see, I've selected margins for left right and top of
