问题 I'm trying to convert from PDF to JPG using PythonMagick, but I can't find a way to set the background color, which by default is changed from transparent to black. I can get the desired result using os.system and the -flatten parameter as shown below. import os os.system('convert -flatten -background \#ffffff -density 400 -adaptive-resize 1900x infile.pdf outfile.jpg') However, PythonMagick does not seem to have a flatten method and the following snippet produces an image with a black

How to handle multi-page images in PythonMagick?

由 烂漫一生 提交于 2019-12-21 04:39:34
问题 I want to convert some multi-pages .tif or .pdf files to individual .png images. From command line (using ImageMagick) I just do: convert multi_page.pdf file_out.png And I get all the pages as individual images (file_out-0.png, file_out-1.png, ...) I would like to handle this file conversion within Python, unfortunately PIL cannot read .pdf files, so I want to use PythonMagick. I tried: import PythonMagick im = PythonMagick.Image('multi_page.pdf') im.write("file_out%d.png") or just im.write(

How to compose with center gravity in PythonMagick

由 十年热恋 提交于 2019-12-11 05:14:46
问题 I did appreciate the answer by Orbling on .composite(): flattened.composite(img, 0, 0, PythonMagick.CompositeOperator.SrcOverCompositeOp) This is the form where the second image is placed to the (0, 0) coordinates of the original image. I tried, but I could not find how the image could be centered to the original. The internal __doc__ says (formatted manually): composite( (Image)arg1, (Image)arg2, (GravityType)arg3 [, (CompositeOperator)arg4]) -> None : C++ signature : void composite(class

问题 I was trying to use PIL to open an (Illustrator) .eps-file, do some changes and save it. I want to set the document to 300 dpi, and color mode to cmyk before opening, creating or interpreting the object. First I tried the same with PythonMagick and it worked like this: import PythonMagick # That's NOT what I want img72 = PythonMagick.Image() img_file = 'epstest.eps' img.read(img_file) img_dens = img72.density() print 'W: %d, H: %d' % (img.size().width(), img.size().height()) # W: 403, H: 2475
