Question

を使用してフォトショップでTIFF処理：

# open a tiff 
# get it's dpi, width, height and colorspace 
# set the dpi, width, height and colorspace 
# and then save the tiff out with no compression and no layers. 

これまでのところ、私が得ている：

from win32com.client.dynamic import Dispatch 
ps = Dispatch("Photoshop.Application") 

file_path = "C:\\Users\\me\\myImg.tif" 
doc = ps.Open(file_path) 

dpi  = doc.Resolution 
width = doc.Width    # in cm 
height = doc.Height   # in cm 

# up to here the code works, but then I try 
doc.Resolution = 72 
ps.ResizeImage(120 , 120) 
ps.PsColorSpaceType(3) # psSRGB 

ps.TiffSaveOptions.ImageCompression = 1 # psNoTIFFCompression 
ps.TiffSaveOptions.Layers = False 
ps.Save() 

# and this last section fails 

助けてください、任意のアイデア、ヒント、魂は非常に高く評価されます：D

多くのgoogelingといくつかの試行錯誤の後、さらに試行錯誤して、私は以下のコードを思いついた。

これは他の人に役立つことを期待しています。

コード

file_path = "C:\\Users\\me\\myImg.tif" 
color_settings = "North America General Purpose 2" 


from win32com.client.dynamic import Dispatch 

ps_app = Dispatch("Photoshop.Application") 

# set photoshop to use pixels as dimensions 
ps_app.Preferences.RulerUnits = 1    # 'for PsUnits --> 1 (psPixels)   
ps_app.Preferences.TypeUnits = 1    # 'for PsTypeUnits --> 1 (psPixels) 

doc = ps_app.Open(file_path)     # Open a file and store open file as doc 
dpi  = doc.Resolution 
width = doc.Width   
height = doc.Height    

cor_res = 1024 

ps_app.ChangeColorSettings(color_settings) 
doc.ResizeImage(cor_res , cor_res , 72) 


options = Dispatch('Photoshop.TiffSaveOptions') 
options.ImageCompression = 1     # ps_appNoTIFFCompression 
options.Layers = False       # no layers 


doc.SaveAs(file_path , options)    # Save with specified options 
doc.Close(2)         # psDoNotSaveChanges
