This functionality is not required in the project rubric since the default quotes are short enough to fit the image in one line. I recommend you follow along with this article and run the code yourself. This way, you will understand and even achieve better results. I considered the following criteria:.

Load the Image. We will be using the extension library pillow to draw text on an image. We shall use the following classes from pillow:. So, I loaded the image with the code. Make sure Pillow is installed. Also, you can replace. Consider using.

Random positioning. The project Meme Generator requires us to randomly select a location on an image where the quote will be drawn. This is very important as it will determine how I will split the text. As we can see from the diagram above, the white rectangle is the area on the image where a random position will be selected. As we will see later, the Y-axis will vary base on two other criteria. Resize the Image. The image is resized with a width of px and automatically generates the height while maintaining aspect ratio Required by the project.

Calculate X boundary, Split text to multiple line and Calculate Y boundary. Later, I calculated the x-axis boundary and then randomly generate the x -point:. We need to import randint in other to use it. Calculating the Y-axis boundary is a bit tricky.

We need to know the number of lines of text and also the line height. The number of lines of text is determined by the text length and the randomly selected X-axis. Consider the images below:. Consider the image to the left, imagine we randomly selected the x-point and y-point at that position.

Given that the text is about 40 characters long and the distance from the x-point to the right boundary of the image is 30px. We notice that the text will overflow. At this point, we can split our text at a maximum length of 30 characters. Hence, our resulting split will have 3 lines of texts of length 30, 30 and However, after splitting we see that the lines of text overflow to the bottom of the image Image to the right.

This can happen when the height from the y-point to the bottom of the image is shorter compared to the number of lines generated from the split times the line height. I did that with the following lines of code:. Split text base on randomly selected X-point and font size of the text.

This will be used to add the appropriate line spacing. We chose h as it extends upward just like tletc. We also choice g as it extends downward just as yp etc. Hence hg covers the height range of all the English characters. The logic is pretty straightforward:.In the first post of this series, I introduced you to the basics of text drawing in Python by adding a greeting text on an image. I also highlighted examples of how I further extended this functionality to create some complex images at work.

For now, we know how to draw text, change the font, and position the text on the image. Multiline Text. In order to do this manually, we need to calculate the width and height of the text.

With the text-width, we determine when we need to move to the next line and with the text-height, we can figure how much space should be left in between the two lines:. The idea is to split the long sentences into multiple shorter sentences and draw each of these, one by one at the correct positions thereby making it look like a multiline text.

This function expects three parameters — the text to draw, an ImageFont class instance and the width of the background image on which the text is to be drawn. When we run this script it returns an array containing 2 shorter lines which fit within the width of the background image.

To draw these lines on the image we have to calculate the correct vertical position of each line.

Python PIL |ImageDraw.Draw.multiline_text()

Whenever we write text, there is an equal amount of space between two lines. For example in this post, the lines have the constant spaces between them. While building this library I faced an issue of varying spaces with most of the input text:. This trick works because h and g cover the height range of all the English characters. We can do this by keeping a reference to the vertical position of the previously drawn line and then adding to it the line height to calculate the vertical position of the new line:.

The text in the latter images looks much better and readable. At Haptikwe believe in experimentation and finding out the best possible way to solve problems.

The above is one such example.

Write text on existing image using Python PIL - Pillow

If the width of the text is smaller than image width. Written by: Vinay Jain.The ImageFont module defines a class with the same name. Instances of this class store bitmap fonts, and are used with the PIL. PIL uses its own font file format to store bitmap fonts. Starting with version 1. For earlier versions, TrueType support is only available as part of the imToolkit package. Load a font file. This function loads a font object from the given bitmap font file, and returns the corresponding font object.

Load font file. Same as loadbut searches for a bitmap font along the Python path. Load a TrueType or OpenType font from a file or file-like object, and create a font object. This function loads a font object from the given file or file-like object, and creates a font object for a font of the given size. Pillow uses FreeType to open font files.

If you are opening many fonts simultaneously on Windows, be aware that Windows limits the number of files that can be open in C at once to Which font encoding to use default is Unicode. Possible encodings include see the FreeType documentation for more information :. This specifies the character set to use.

It does not alter the encoding of any text provided in subsequent operations. If the font uses antialiasing, the bitmap should have mode L and use a maximum value of Otherwise, it should have mode 1. Used by some graphics drivers to indicate what mode the driver prefers; if empty, the renderer may return either mode. Note that the mode is always a string, to simplify C-level implementations. Create a copy of this FreeTypeFont object, using any specified arguments to override the settings.

Direction of the text. Requires libraqm. A list of OpenType font features to be used during text layout. Language of the text. Different languages may use different glyph shapes or ligatures. This parameter tells the font which language the text is in, and to apply the correct substitutions as appropriate, if available.Hardware manufacturers, researchers, software developers work together to build great products: smartphones, smartwatches, smart TVs, cameras all with the study of computer graphics.

Despite the fact that computer graphics has evolved so fast and the development of softwares like Adobe Photoshop, Adobe Illustrator, Sketch has made our lives easier to a great extent, we still cannot generate images on-the-fly with them. And we cannot get there by time-travel, but surely with code! I assume you have Python and pip installed on your computer, but if not, follow the steps in the links to set up the development environment.

For creating ImageFont objects we also need font ttf, otf files. With some fonts, you might have to pass an optional parameter encoding which tells the ImageFont module which encoding to use while opening the font file. Computer graphics have an inverted coordinate system, the origin 0, 0 that lies at the top-left corner of the image. While you save the image, you can pass optional parameters like optimize and quality to control the size of the output image.

This generates an output image optimized. While at work, I recently developed a feature which demanded the creation of a leaderboard image on-the-flywith user-specific quiz score data. And just with a few lines of code, I was able to create an image like this:. It looked great and we decided to use the idea of creating images on-the-go, for other use-cases as well.

The code we used in this post is not sufficient to draw text boxes as shown in the images above. Please do give us your feedback if any in the comments section below. Categories Open Source Python.

Written by: Vinay Jain.The ImageDraw module provide simple 2D graphics for Image objects.

You can use this module to create new images, annotate or retouch existing images, and to generate graphics on the fly for web use. The graphics interface uses the same coordinate system as PIL itself, with 0, 0 in the upper left corner. To specify colours, you can use numbers or tuples just as you would use with Image. In PIL 1. PIL supports the following string formats:. Common HTML colour names. The ImageDraw provides some standard colour names, based on the colors supported by the X Window system and most web browsers.

Colour names are case insensitive, and may contain whitespace. The former contains font metrics, the latter raster data. Note that this function depends on third-party libraries, and may not available in all PIL builds. This allows you to draw directly to the screen. Draws an arc a portion of a circle outline between the start and end angles, inside the given bounding box. Draws a bitmap mask at the given position, using the current fill colour for the non-zero portions. The outline option gives the colour to use for the chord outline.

The fill option gives the colour to use for the chord interior. The outline option gives the colour to use for the ellipse outline. The fill option gives the colour to use for the ellipse interior. The coordinate list can be any sequence object containing either 2-tuples [ x, y… ] or numeric values [ xy… ].

It should contain at least two coordinates.The ImageDraw module provides simple 2D graphics for Image objects. You can use this module to create new images, annotate or retouch existing images, and to generate graphics on the fly for web use.

For a more advanced drawing library for PIL, see the aggdraw module. The graphics interface uses the same coordinate system as PIL itself, with 0, 0 in the upper left corner.

Any pixels drawn outside of the image bounds will be discarded. To specify colors, you can use numbers or tuples just as you would use with PIL. See Color Names for the color names supported by Pillow. The former contains font metrics, the latter raster data. To load a bitmap font, use the load functions in the ImageFont module. Note that this function depends on third-party libraries, and may not available in all PIL builds.

Draws an arc a portion of a circle outline between the start and end angles, inside the given bounding box. Draws a bitmap mask at the given position, using the current fill color for the non-zero portions.

This is equivalent to doing image. To paste pixel data into an image, use the paste method on the image itself. Same as arcbut connects the end points with a straight line.
