imshow¶
The matplotlib function
imshow()
creates an image from a2-dimensional numpy array. The image will have one square for eachelement of the array. The color of each square is determined by the value of the correspondingarray element and the color map used by imshow()

Drag and Drop the files in the browser to reorder - drag in between each other, or swap them - drag one on top of the other.

- Common Names: Blend, Merge Brief Description. This operator forms a blend of two input images of the same size. Similar to pixel addition, the value of each pixel in the output image is a linear combination of the corresponding pixel values in the input images. The coefficients of the linear combination are user-specified and they define the ratio by which to scale each image before.
Note. Color maps assign colors to numbers from the range [0, 1].By default
imshow()
Zoc terminal 7 24 3 download free. scales elements of the numpy array so that the smallest elementbecomes 0, the largest becomes 1, and intermediate values are mapped to the interval[0, 1] by a linear function. Optionally imshow()
can be called with arguments vmin
and vmax
. In such case all elements of the array smaller or equal to vmin
are mappedto 0, all elements greater or equal to vmax
are sent to 1, and the elements betweenvmin
and vmax
are mapped in a linear fashion into the interval [0,1].imsave¶
The
imsave()
function is similar to imshow()
, but instead ofdisplaying an image it saves it to a file. In the file eachelement of the numpy array describes one pixel. The imsave()
function does not have the interpolation
argument.Here is a file created by the above code.
RGB Colors¶
RGB is a color model commonly used to describe colors displayed oncomputer screens. RGB uses three basic colors: red, green, and blue.Other colors are obtained by mixing these basic components in variousproportions.
Ffworks 1 7 0 3. In the RGB model each color is described by three numbers that giveintensities of red, green, and blue. In matplotlib these numbers arebetween 0 (full off) to 1 (full on), but in many other computerapplications they are taken to be integers between 0 and 255. The triple
(0,0,0)
represents the black color and (1,1,1)
(or(255,255,255)
) represents white.RGB coordinates can be used to specify colors in all matplotlib plottingfunctions:
imshow and imsave with RGB colors¶
The functions
imshow()
and imsave()
can create images withcolors specified by RGB coordinates. To do thiswe use a 3-dimensional numpy array a
of dimensions m (times)n (times) 3. Such array consists of three slices a[:,:,0]
,a[:,:,1]
, and a[:,:,2]
that give RGB coordinates of colors inthe image.Exercise. Recreate the following image:
imread¶
While
imshow()
and imsave()
produce an image from a numpy array,the imread()
function takes as its argument an image file andconverts it into a numpy array. The following code uses the filetiger.jpg.img_array
a 3-dimensional numpy array that describes RGB coordinatesof all pixels of the image:[[[ 60 73 19] [ 62 75 21] [ 63 78 23] …, [211 212 170] [216 221 181] [221 227 191]] [[ 53 65 15] [ 53 67 16] [ 55 69 16] …, [213 214 170] [220 222 183] [225 229 192]] [[ 44 57 11] [ 45 58 12] [ 45 61 14] …, [215 214 170] [220 222 182] [227 229 192]] …, [[ 91 123 47] [ 89 121 45] [ 93 121 47] …, [ 81 75 39] [ 75 62 30] [ 76 59 29]] [[ 96 128 52] [ 87 117 43] [ 79 106 35] …, [ 76 70 34] [ 72 59 25] [ 74 57 27]] [[ 85 116 40] [ 73 103 29] [ 62 89 18] …, [ 74 68 32] [ 72 59 25] [ 77 61 28]]]
Notice that entries of
img_array
are positive integers. This is the casebecause, as it was mentioned above, in computer applications RGB coordinates areoften represented by integers in the range 0-255. For the purposes ofmanipulating this array it will be convenient to convert its entriesinto floats in the range 0.0-1.0. This can be done by dividing allentries of img_array
by 255:[[[ 0.23529412 0.28627451 0.0745098 ] [ 0.24313725 0.29411765 0.08235294] [ 0.24705882 0.30588235 0.09019608] …, [ 0.82745098 0.83137255 0.66666667] [ 0.84705882 0.86666667 0.70980392] [ 0.86666667 0.89019608 0.74901961]] [[ 0.20784314 0.25490196 0.05882353] [ 0.20784314 0.2627451 0.0627451 ] [ 0.21568627 0.27058824 0.0627451 ] …, [ 0.83529412 0.83921569 0.66666667] [ 0.8627451 0.87058824 0.71764706] [ 0.88235294 0.89803922 0.75294118]] [[ 0.17254902 0.22352941 0.04313725] [ 0.17647059 0.22745098 0.04705882] [ 0.17647059 0.23921569 0.05490196] …, [ 0.84313725 0.83921569 0.66666667] [ 0.8627451 0.87058824 0.71372549] [ 0.89019608 0.89803922 0.75294118]] …, [[ 0.35686275 0.48235294 0.18431373] [ 0.34901961 0.4745098 0.17647059] [ 0.36470588 0.4745098 0.18431373] …, [ 0.31764706 0.29411765 0.15294118] [ 0.29411765 0.24313725 0.11764706] [ 0.29803922 0.23137255 0.11372549]] [[ 0.37647059 0.50196078 0.20392157] [ 0.34117647 0.45882353 0.16862745] [ 0.30980392 0.41568627 0.1372549 ] …, [ 0.29803922 0.2745098 0.13333333] [ 0.28235294 0.23137255 0.09803922] [ 0.29019608 0.22352941 0.10588235]] [[ 0.33333333 0.45490196 0.15686275] [ 0.28627451 0.40392157 0.11372549] [ 0.24313725 0.34901961 0.07058824] …, [ 0.29019608 0.26666667 0.1254902 ] [ 0.28235294 0.23137255 0.09803922] [ 0.30196078 0.23921569 0.10980392]]]
We can use
imshow()
to display the image:The image can be modified by changing the numpy array. For example,if we multiply the array by a number (0leq x leq 1) we will darkenthe image:
We can crop the image by taking a slice of the array:

API and Extension Header Files
Because extensions vary from platform to platform and driver to driver, OpenGL ES segregates headers for each API version into a header for the core API (OpenGL ES 1.0, 1.1, 2.0, 3.0, 3.1 and 3.2) and a separate header defining extension interfaces for that core API. These header files are supplied here for developers and platform vendors. They define interfaces including enumerants, prototypes, and for platforms supporting dynamic runtime extension queries, such as Linux and Microsoft Windows, function pointer typedefs. Please report problems as Issues in the OpenGL-Registry repository.
In addition to the core API and extension headers, there is also an OpenGL ES version-specific platform header file intended to define calling conventions and data types specific to a platform.
Almost all of the headers described below depend on a platform header file common to multiple Khronos APIs called <KHR/khrplatform.h>.
Vendors may include modified versions of any or all of these headers with their OpenGL ES implementations, but in general only the platform-specific OpenGL ES and Khronos headers are likely to be modified by the implementation. This makes it possible for developers to drop in more recently updated versions of the headers obtained here, typically when new extensions are supplied on a platform.
