Using Image, we will read that image and print its dimensions. We will import the Image from wand.image. For example, we will try to find the dimensions of the following image of New York City. Reading dimensions of an imageįirst, we shall use Wand to get the dimensions of a given image. In python, we will be executing all the ImageMagick commands using Wand.
Code: convert -font DejaVu-Sans-Mono-Bold -pointsize 14 -gravity northwest label:infile.txt outfile.jpg. It has the feature to draw multi line text from a file An example of its use is.
#Imagemagick text install#
!pip install wand Using Wand for ImageMagick Python In the end Imagemagick is the tool Imagemagics 'convert' can draw text into an image. Then, to install Wand in python, use the below pip install command. To install ImageMagick in python, we will be installing it in the form of an apt. Using Wand, all the functionalities of MagickWand API can be implemented. In python, Wand is a binding developed by Imagemagick. We shall implement the ImageMagick commands using Wand. To use the ImageMagick software, you can install it from ‘ .’ Then, you can execute the commands from the command line.īut here, we will be using ImageMagick through python. Because of that, we can apply operations to different images.Īpart from this, we can use Imagemagick to rotate images and apply transformations, cropping images, adjust image colors, apply special effects on images and draw lines, polygons, etc., on the images. ImageMagick allows us to combine image processing operations in a script. Due to its versatility, it is widely in use. Imagemagick can read and write images in over 200 different formats such as JPEG, PNG, GIF, PDF, TIFF, SVG, etc. It is also capable of reading and writing images of different formats.
#Imagemagick text software#
genius.Ĭoming up with super genius ways to compare the average color of a line, to tell if it was actual text or "blank space".Imagemagick in python is a software tool which is used to convert images from one format to another format. like using ImageMagick to add line numbers to a PDF: Then you get the REALLY obscure/ingenious stuff.
#Imagemagick text pdf#
a whole PDF full of little speckles? Or the tiny end of a comma or an accent disappearing. Or complicated edges/lines would go poof (like a dashed line in a graph, or a very thin line separating the bottom of the text from the footnote section).ĭefinitely helped me in many cases though, and helped cut down on the size of some speckled PDFs/Images DRAMATICALLY.Īnd you had to weigh what would be worse. The general options for setting fonts, colors and postions are similar. Which function to use depends on how much and what type of control you want to have over the text that is written. like the very tip of a comma, or the tip of a serif font, or little umlaut above a character in a footnote, or a badly scanned period would just poof. The ImageMagick functions -annotate, -draw, -caption and -label can all be used for writing text to images. BUT the downfall was sometimes the fine details would disappear. It did a pretty fantastic job compared to ANYTHING I ever found before/since. Then it would reverse the expansion and use the diff image to try to return it to its original form. This would get rid of little 1x1, 1x2, 2x1, 2x2, 3x2, specs of dust all over the page. Then step through and remove any group of non-fully-black pixels that was smaller than X x Y. If I remember correctly, they did it by shrinking, then expanding pixels, then creative a diff image. If you did a search for it in Google, it was one of those where you get "6 hits" and/or it was buried on "page 1000" of a normal search (like "Imagemagick despeckling" or "cleaning speckles in PDF scans"). I spent days reading everything on Google, I somehow stumbled upon a REALLY obscure Imagemagick post that had the (close-to-perfect) solution. I remember when I was trying to come up with a despeckling solution to clean up PDF scans. but instead of me doubling/tripling the size, I just turn it into the actual Unicode characters instead. Most of the time when I run across Doitsu's problem in all the books I work on is microscopic images of Greek text.
There has to be much better Imagemagick solutions that exist out there. That method was just something I came up with in a few hours as a ROUGH resizing (better than nothing, but definitely not something I would use in an ebook for sale). I will have to research this topic/methods a lot more as well. I may change the way k2pdfopt does contrast adjustment now. After reading about how the contrast-stretch option works in ImageMagick, I've learned something new.
