Hi All,
I have an issue with the following code which I ain't able to
trace. The code is for uploading images, generating the thumbnails
,watermarking the image and saving the watermarked thumbnail to a path on
the system. While this is working fine on windows system, it *fails *miserably
on linux system. On debian system it does not save the file name as the
record name and it saves it with an incremental valued name.
For example if the thumbnail should be 114.thumbnail.jpg on the system it
saves as 91.thumbnail.jpg or such name. Note that there is a gap in naming
for example there are a few files with names 88.thumbnail.jpg then
90.thumbnail.jpg .. and then 112.thumbnail.jpg. Basically the records ID
value appended with .thumbnail.jpg. When a new image is uploaded it should
ideally start from 115.thumbnail.jpg as that is the value that is generated
and saved in the database. but it takes other value instead when saving the
file on the disk may be (if 90.thumnail.. exists already) it will save it
as 91.thumbnail.jpg
CODE BELOW -
if form.accepts(request.vars,session):
recordsID= form.vars.id
import platform
is_windows=(platform.system().lower().find("win") > -1)
is_linux=(platform.system().lower().find("lin") > -1)
is_mac=(platform.system().lower().find("mac") > -1)
if (is_windows == True):
#print "is windows"
foto_path = (request.folder + "static\\user_uploads\\" +
upload_pic)
infile = foto_path
thumbnail_filename = ("%s" % recordsID + ".thumbnail.jpg")
outfile = (request.folder + "static\\thumbs\\" +
thumbnail_filename )
thumbpath = os.path.join(request.folder, 'static', 'thumbs\\') +
thumbnail_filename
elif (is_linux == True):
#print "is linux"
foto_path = (request.folder + "static/user_uploads/" +
upload_pic)
infile = foto_path
thumbnail_filename = ("%s" % recordsID + ".thumbnail.jpg")
#outfile = (request.folder + "static/thumbs/" +
thumbnail_filename )
thumbpath = os.path.join(request.folder, 'static', 'thumbs/') +
thumbnail_filename
outfile = (thumbpath) ## Changed on AUG 25
db(db.fotoz.id==recordsID).update(imgthumb=thumbnail_filename,
imgthumbpath=thumbpath) ##outfile
if infile != outfile:
try:
im = Image.open(infile)
im.thumbnail(size)
#Check for image format
image_format = (im.format)
#print ("Image format: ", image_format)
### ================ Watermark stuff ======================
width, height = im.size
draw = ImageDraw.Draw(im)
watermark_text = "WATERMARK"
watermark_font = ImageFont.truetype('arial.ttf', 20)
textwidth, textheight = draw.textsize(watermark_text,
watermark_font)
# calculate the x,y coordinates of the text
margin = 5
x = width - textwidth - margin
y = height - textheight - margin
# draw watermark in the bottom right corner
## Specify this to fill font with red color ,
fill=(128,0,0,128)) OR #, fill=shadowcolor) OR fill="red" or
fill="#ff0000" -- work
draw.text((x, y), watermark_text, font=watermark_font,
opacity=0.25)
## --- Watermark text ends ---
#Process various image formats for making thumbnails.
Currently supporting JPG/JPEG, GIF and PNG
if (image_format == "JPEG"):
im.save(outfile, "JPEG")
if (image_format == "GIF"):
im.save(outfile, "GIF")
if (image_format == "PNG"):
im.save(outfile, "PNG")
except IOError:
print("Cannot create thumbnail (un-recognized format) for ",
infile)
pass
If any one has any idea please suggest -
Regards,
Rahul
