Ja som pracoval na krátky skript, ktorý by plátok tiff súbor na menšie kúsky.
Súbory sú väčšie ako typické (najväčší súbor má 16000 x 28800 pixelov 1 bit hĺbka)
Moja predstava je, aby plodín každá tieto obdĺžniky a uložiť ako nový súbor s rovnakým rozlíšením ako pôvodný obrázok
from PIL import Image
Image.MAX_IMAGE_PIXELS = None
rows = 9
cols = 5
im = Image.open("Patches_TP_2540.tif")
width, heigth = im.size
res = 2540
print(width, heigth)
patchSize = int(width / cols)
offset_x_tl = 0
offset_y_tl = 0
for r in range(rows):
offset_y_tl = r * patchSize
for c in range(cols):
print(r, c)
offset_x_tl = c * patchSize
offset_y_br = offset_y_tl + patchSize
offset_x_br = offset_x_tl + patchSize
print(offset_x_tl, offset_y_tl, offset_x_br, offset_y_br)
croped_area = im.crop((offset_x_tl, offset_y_tl, offset_x_br, offset_y_br))
croped_area.save("Patch_"+ str(res) +"_" + str(r) + "_" + str(c) +".tiff", dpi=(2540,2540))
print("Done!")
Ak som sa spustiť tento kód sa končí bez potlače Hotovo! Ak môžem odstrániť croped_area a príkaz uložiť, kód je spustený v poriadku. Vytvoriť nový Obrázok a uložte ho workds tiež.
Tiež som tryed pomocou temp obraz s im.kopírovanie(). Ak robím to, kód zastaví na kopírovanie procesu.
Možno, že niekto mi môže pomôcť s týmto problémom, a má nejaké triky, ako vyriešiť problém.
Vďaka za čítanie, Timo
