python - How do I stop PIL from swapping height/width when rotating an image 90°? -

-

i using pil rotate image. works in general, except when rotate image 90° or 270°, in case x , y measurements swap. is, given image:

>>> img.size (93, 64)

if rotate 89° this:

>>> img.rotate(89).size (93, 64)

and 91° this:

>>> img.rotate(91).size (93, 64)

but if rotate either 90° or 270°, find height , width swapped:

>>> img.rotate(90).size (64, 93) >>> img.rotate(270).size (64, 93)

what's correct way prevent this?

i'm hoping comes more graceful solution, seems work now:

img = image.open('myimage.pbm')  frames = [] angle in range(0, 365, 5):     # rotate image expand=true, makes canvas     # large enough contain entire rotated image.     x = img.rotate(angle, expand=true)      # crop rotated image size of original image     x = x.crop(box=(x.size[0]/2 - img.size[0]/2,                x.size[1]/2 - img.size[1]/2,                x.size[0]/2 + img.size[0]/2,                x.size[1]/2 + img.size[1]/2))      # stuff rotated image here.

for angles other 90° , 270° results in same behavior if set expand=false , don't bother crop operation.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
