ImageDraw module of the Python image processing library Pillow PIL provides a number of methods for drawing figures such as circle, square, and straight line. Prepare an Image object of a background image image for drawing a figure and use it to create a Draw object. Don't forget to import Image and ImageDraw. Here, create a solid image with Image. The mode, size, and fill color are specified in parameters. Draw an ellipse, a rectangle, and a straight line as an example. The parameters will be described later.
In linepolygonand pointmultiple coordinates are specified instead of two points representing a rectangular area. The specification format of color is the same as fill above. The default is None no border. As of version 4. See the official document for details. Specifying a square results in a true circle. The example of lines linepolygon polygonpoint point is as follows. Since the point is 1 pixel, it is hard to see but it is drawn on the right side.
An arc, a chord bowand a pie touching the rectangular area specified by the argument xy are drawn. Example of arc arcchord chordpie pieslice is as follows. In the previous examples, figures are drawn on the solid image generated by Image. If an existing image file is read by Image.AutoCAD Text Command Tutorial - Text Size - Text Style - Text Scale
Draw im draw. Python Pillow Image Processing.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 file, and create a font object. This function loads a font object from the given file, and creates a font object for a font of the given size. 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. Pillow PIL Fork 3. Parameters: filename — Name of font file. Returns: A font object. Raises: IOError — If the file could not be read. Parameters: font — A truetype font file. See the FreeType documentation for more information.
New in version 1. Parameters: text — Text to render. Read the Docs v: 3.
IOError — If the file could not be read.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. New in 1. Note that line joins are not handled well, so wide polylines will not look good. Note: The width option is broken in 1. The line is drawn with twice the width you specify. This will be fixed in 1.
Same as arcbut also draws straight lines between the end points and the center of the bounding box.Here, the method of acquiring the image size width, height will be described. In OpenCV, the image size width, height can be obtained as a tuple with the attribute shape of ndarray and the attribute size of PIL. Image in Pillow PIL. Note that the order of width and height is different. The size width, height of the image can be acquired from the attribute shape indicating the shape of ndarray.
Not limited to OpenCV, the size of the image represented by ndarraysuch as when an image file is read by Pillow and converted to ndarrayis obtained by shape. In the case of a color image, it is a 3D ndarray of row height x column width x color 3. An example where the number of colors number of channels is not used is as follows.
If you want to get tuples in the order of width, heightyou can use slice like the following example. When setting the size to cv2.
For grayscale monochrome images, it is a 2D ndarray of rows height x columns width.
Putting Text On Image Using Python – Part I
If you want to assign width and height to variables, you can apply the following to either color or grayscale images:. If you want to get a width, height tuple, you can use slice.
The image can be either color or grayscale if it is written as follows. Image object obtained by reading an image with Pillow PIL has attributes sizewidthand height. The width and height can also be acquired with the attributes width and height. Here, the following contents will be described.
OpenCV: Get image size width, height with ndarray.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.
Putting Text on Images Using Python – Part 2
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. In my next Blog post, I will be writing about how to center align text horizontally and vertically in an image using Python.

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. 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.
Python pill draw text on image
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.
The line width, in pixels. Note that line joins are not handled well, so wide polylines will not look good. Same as arc, but also draws straight lines between the end points and the center of the bounding box. The polygon outline consists of straight lines between the given coordinates, plus a straight line between the last and the first coordinate.
The Draw class contains a constructor and a number of methods which are provided for backwards compatibility only.
For this to work properly, you should either use options on the drawing primitives, or these methods. Do not mix the old and new calling conventions. Pillow PIL Fork 3. Draw im draw. Draw txt draw text, half opacity d. Note that the image will be modified in place. Parameters: im — The image to draw in. For all other modes, this argument must be the same as the image mode.
If omitted, the mode defaults to the mode of the image. Parameters: xy — Four points to define the bounding box.
