From stackoverflow I learned how to set image properties in LibreOffice Writer with pyhton macros, via com.sun.star.text.WrapTextMode. Now I use that to set the text wrap to THOUGHT. Now I would like to set the image to background, like a watermark.
In LibreOffice Writer interactively I select an image, right-click on it and the context menu contains the "Wrap" commands, one is "Wrap Through" and the other one is "In Background".
In the python macro I have the following code (from Insert several images at once using macro scripting in LibreOffice and from the often quoted Andrew Pitonyak):
from com.sun.star.text.WrapTextMode import THROUGHT
and then to insert the image:
img = doc.createInstance('com.sun.star.text.TextGraphicObject')
element_url = 'file://' + file_name
img.GraphicURL = element_url
img.Surround = THROUGHT
text.insertTextContent(cursor, img, False)
So what is the code to put it "In Background"?
MRI shows that setting "In Background" causes the Opaque attribute to be false. So add this to the code:
img.Opaque = False
By the way, Surround is deprecated. Try setting TextWrap to THROUGHT instead.

I’m using rhino.compute to calculate a mesh.
How could I convert the 3dm decoded mesh to an STL file?
Currently, I can only save it as a 3dm:
import compute_rhino3d.Grasshopper as gh
import rhino3dm
output = gh.EvaluateDefinition(definition_path, trees)
mesh = output['values'][0]['InnerTree']['{0}'][0]["data"]
mesh = rhino3dm.CommonObject.Decode(json.loads(mesh))
doc = rhino3dm.File3dm()
doc.Objects.AddMesh(mesh)
doc.Write("model.3dm", version=0)
Thank you very much!
You can use Rhino.RhinoDoc.WriteFile to write to all file types that rhino conventionally supports for exporting.
def ExportStl():
#Path to save File.
filepath = r"C:\Temp\TestExport.stl"
#Create write options to specify file info.
write_options = Rhino.FileIO.FileWriteOptions()
#Export all geometry, not just selected geometry.
write_options.WriteSelectedObjectsOnly = False
#Write File.
result = Rhino.RhinoDoc.ActiveDoc.WriteFile(filepath, write_options)
ExportStl()
In this case, I'm using the Rhino 'RunPythonScript' command with the open ActiveDoc but in your example, you could use doc.WriteFile(filepath, write_options) instead.
When you first run this, there is a .stl export dialogue that has export options. This window can be suppressed to the command line with write_options.SuppressDialogBoxes = True.
Or you can check the 'Always use these settings. Do not show this dialogue again.' option and it will not interrupt export in the future.
Your example suggests you may be working in a headless environment so I'm not sure how these dialogues would be handled in that scenario.
I would like to relink a Photoshop Smart Object to a new file using Python.
Here's a screenshot of the button that's used in Photoshop to perform this action - "Relink to File":
I've found some solutions in other programming languages but couldn't make them work in Python, here's one for example: Photoshop Scripting: Relink Smart Object
Editing Contents of a Smart Object would also be a good option, but I can't seem to figure that one out either.
Here's a screenshot of the button to Edit Contents of a Smart Object:
So far I have this:
import win32com.client
psApp = win32com.client.Dispatch('Photoshop.Application')
psDoc = psApp.Application.ActiveDocument
for layer in psDoc.layers:
if layer.kind == 17: # layer kind 17 is Smart Object
print(layer.name)
# here it should either "Relink to File" or "Edit Contents" of a Smart Object
I have figured out a workaround! I simply ran JavaScript in Python.
This is the code to Relink to File.... You could do a similar thing for Edit Contents but I haven't tried it yet, as relinking works better for me.
Keep in mind the new_img_path must be a raw string as far as I'm aware, for example:
new_img_path = r"C:\\Users\\miha\\someEpicPic.jpg"
import photoshop.api as ps
def js_relink(new_img_path):
jscode = r"""
var desc = new ActionDescriptor();
desc.putPath(stringIDToTypeID('null'), new File("{}"));
executeAction(stringIDToTypeID('placedLayerRelinkToFile'), desc, DialogModes.NO);
""".format(new_img_path)
JavaScript(jscode)
def JavaScript(js_code):
app = ps.Application()
app.doJavaScript(js_code)
I'm having trouble trying to create Table of Contents objects in a PDF file. I'm not sure whether I've understood the process from Apple's limited documentation.
I'm using python, but cogent examples in any language are welcome to explain how it's supposed to work. The code creates a new PDF document, but there's no outline item visible in Preview. I've tried just using myOutline as the root object, but that doesn't work either.
pdfURL = NSURL.fileURLWithPath_(infile)
myPDF = Quartz.PDFDocument.alloc().initWithURL_(pdfURL)
if myPDF:
# Create Destination
myPage = myPDF.pageAtIndex_(1)
pagePoint = Quartz.CGPointMake(0,0)
myDestination = Quartz.PDFDestination.alloc().initWithPage_atPoint_(myPage, pagePoint)
# Create Outline
myOutline = Quartz.PDFOutline.alloc().init()
myOutline.setLabel_("Interesting")
myOutline.setDestination_(myDestination)
# Create a root Outline and add the first outline as a child
rootOutline = Quartz.PDFOutline.alloc().init()
rootOutline.insertChild_atIndex_(myOutline, 0)
# Add the root outline to the document and save
myPDF.setOutlineRoot_(rootOutline)
myPDF.writeToFile_(outfile)
EDIT: Actually, the outline IS getting saved to the new file: I can read it programmatically, and it appears in Acrobat as a Bookmark; however, it doesn't show up in Preview's Table of Contents (yes, I checked for the "Hide" thing). If I add another Bookmark in Acrobat, then both show up in Preview.
So I guess that either I'm still doing something wrong which doesn't quite 'finish' the PDFOutline data properly, and Acrobat is being kind; or there's a massive bug in PDFKit that means you can't write PDFOutlines properly. I get the same behaviour on Mountain Lion, FWIW.
This does appear to be a bug in Preview. It will not list the Table of Contents if it contains ONLY ONE child entry.
If I add more Outlines with the code above, then all of them appear in Preview. If use other software to remove all but one entries in the Table of Contents, then Preview will not show any.
I want to make some operationi automatic.But I met some trouble in export the image after I bake it.At first I try to use "bpy.ops.object.bake_image()" to bake the image.But the result image can not be active in uv editor.
The bake was success,but the result image didn't appear in the uv editor.It need selected so that I could export the file.
So I search the document ， and found the other command "bpy.ops.object.bake()".It have a parameter "save_mode",but I still met some obstacle in using this command.It always point me out that " RuntimeError: error: No active image found in material "material" (0) for object "1.001" ".
Here is the official document about this two command:
https://docs.blender.org/api/blender_python_api_2_78a_release/bpy.ops.object.html?highlight=bake#bpy.ops.object.bake
Can anyone try to give me some solution or some advice that how can I make this thing right.
Many of blenders operators require a certain context to be right before they will work, for bpy.ops.image.save() that includes the UV/Image editor having an active image. While there are ways to override the current context to make them work, it can often be easier to use other methods.
The Image object can save() itself. If it is a new image you will first need to set it's filepath, you may also want to set it's file_format.
img = bpy.data.images['imagename']
img.filepath = '/path/to/save/imagename.png'
img.file_format = 'PNG'
img.save()
I need to generate a customized PDF copy of a template document.
The easiest way - I thought - was to create a source PDF that has some placeholder text where customization needs to happen , ie <first_name> and <last_name>, and then replace these with the correct values.
I've searched high and low, but is there really no way of basically taking the source template PDF, replace the placeholders with actual values and write to a new PDF?
I looked at PyPDF2 and ReportLab but neither seem to be able to do so.
Any suggestions? Most of my searches lead to using a Perl app, CAM::PDF, but I'd prefer to keep it all in Python.
There is no direct way to do this that will work reliably. PDFs are not like HTML: they specify the positioning of text character-by-character. They may not even include the whole font used to render the text, just the characters needed to render the specific text in the document. No library I've found will do nice things like re-wrap paragraphs after updating the text. PDFs are for the most part a display-only format, so you'll be much better off using a tool that turns markup into a PDF than updating the PDF in-place.
If that's not an option, you can create a PDF form in something like Acrobat, then use a PDF manipulation library like iText (AGPL) or pdfbox, which has a nice clojure wrapper called pdfboxing that can handle some of that.
From my experience, Python's support for writing to PDFs is pretty limited. Java has, by far, the best language support. Also, you get what you pay for, so it would probably be worth paying for a iText license if you're using this for commercial purposes. I've had pretty good results writing python wrappers around PDF-manipulation CLI tools like pdfboxing and ghostscript. That will probably be much easier for your use case than trying to shoehorn this into Python's PDF ecosystem.
There is no definite solution but I found 2 solutions that works most of the time.
In python https://github.com/JoshData/pdf-redactor gives good results. Here is the example code:
# Redact things that look like social security numbers, replacing the
# text with X's.
options.content_filters = [
# First convert all dash-like characters to dashes.
(
re.compile(u"Tom Xavier"),
lambda m : "XXXXXXX"
),
# Then do an actual SSL regex.
# See https://github.com/opendata/SSN-Redaction for why this regex is complicated.
(
re.compile(r"(?<!\d)(?!666|000|9\d{2})([OoIli0-9]{3})([\s-]?)(?!00)([OoIli0-9]{2})\2(?!0{4})([OoIli0-9]{4})(?!\d)"),
lambda m : "XXX-XX-XXXX"
),
]
# Perform the redaction using PDF on standard input and writing to standard output.
pdf_redactor.redactor(options)

In ruby https://github.com/gettalong/hexapdf works for black out text.
Example code:
require 'hexapdf'
class ShowTextProcessor < HexaPDF::Content::Processor
def initialize(page, to_hide_arr)
super()
#canvas = page.canvas(type: :overlay)
#to_hide_arr = to_hide_arr
end
def show_text(str)
boxes = decode_text_with_positioning(str)
return if boxes.string.empty?
if #to_hide_arr.include? boxes.string
#canvas.stroke_color(0, 0 , 0)
boxes.each do |box|
x, y = *box.lower_left
tx, ty = *box.upper_right
#canvas.rectangle(x, y, tx - x, ty - y).fill
end
end
end
alias :show_text_with_positioning :show_text
end
file_name = ARGV[0]
strings_to_black = ARGV[1].split("|")
doc = HexaPDF::Document.open(file_name)
puts "Blacken strings [#{strings_to_black}], inside [#{file_name}]."
doc.pages.each.with_index do |page, index|
processor = ShowTextProcessor.new(page, strings_to_black)
page.process_contents(processor)
end
new_file_name = "#{file_name.split('.').first}_updated.pdf"
doc.write(new_file_name, optimize: true)
puts "Writing updated file [#{new_file_name}]."
In this you can black out text on select text will be visible.
As another solution you may try Aspose.PDF Cloud SDK for Python, it provides the feature to replace text in a PDF document.
First thing first, install the Aspose.PDF Cloud SDK for Python
pip install asposepdfcloud
Sample Code upload PDF file to your cloud storage and replace multiple strings in a PDF document
import os
import asposepdfcloud
from asposepdfcloud.apis.pdf_api import PdfApi
# Get App key and App SID from https://aspose.cloud
pdf_api_client = asposepdfcloud.api_client.ApiClient(
app_key='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
app_sid='xxxxx-xxxx-xxxx-xxxx-xxxxxxxx')
pdf_api = PdfApi(pdf_api_client)
filename = '02_pages.pdf'
remote_name = '02_pages.pdf'
#upload PDF file to storage
pdf_api.upload_file(remote_name,filename)
#Replace Text
text_replace1 = asposepdfcloud.models.TextReplace(old_value='origami',new_value='aspose',regex='true')
text_replace2 = asposepdfcloud.models.TextReplace(old_value='candy',new_value='biscuit',regex='true')
text_replace_list = asposepdfcloud.models.TextReplaceListRequest(text_replaces=[text_replace1,text_replace2])
response = pdf_api.post_document_text_replace(remote_name, text_replace_list)
print(response)
