Great! Meanwhile, I've greatly updated the EMF sample generator to produce 84 variations of valid metafiles for testing purposes. It can produce variations with different values for:
- SetWindowOrgEx (on or off)
- SetWorldTransform (including none, normal, scale, translate, rotate, shear, reflect)
- Clipping regions (on or off)

Metafiles are visible in IrfanView: RO714yu.png

Source code: https://gist.github.com/jonjbar/5e32409 … 349c66ff07

Hopefully, this could help test and enhance the SynPDF producer in the future.

AFAIR IrfanView is using the Windows GDI rendering directly.
So if it can't display anything, there is something wrong with the content.

A simple VCL app should be able to display this EMF.

You're right. I could see the result in Illustrator so I though it was good enough for a quick and dirty first test. I'll see if that can be improved.

rvk wrote:

BTW. That test project doesn't create a EMF which contains an offset WinOrg or non-standard scale, like your original code from this topic does.
So it wouldn't detect the regression for which you opened this topic lol

That was just a quick and dirty first try to produce sample EMF files for testing purposes as you said previously: "For that we need more diverse EMF files."
I believe that it would be perfectly possible to generate the WinOrg using something like this at the beginning of the process:

      // Set the window origin
      SetWindowOrgEx(MetaFileDC, XOrigin, YOrigin, nil);

#6 Re: PDF Engine » Automated PDF testing » 2024-05-15 13:42:20

As a starting point, here is a Python script that I've created with the help of ChatGPT and here is what it does:
- It extracts all pages from a reference PDF and a generated PDF as PNG images
- It compares the number of pages and fail if different
- It compares each pages and for each of them, it outputs the difference as both a difference image, and a percentage
- It outputs the final result as a consistent and clear textual content for easy integration with automated tests

So I support we could create multiple small command line programs to produce PDFs using SynPDF and test most parts of the library, including MetaFiles conversion. Those programs generate the PDF in a path specified by arguments, so that they can be used to generate the reference PDFs at first (and update them if needed), and re-generate them in the correct folder during automated tests.
Then the Python script is called for each files in the reference folder and fails based on specific conditions.

So I've added debug code to visualize the clipping rectangle and it looks like it is simply offset by the PDF page's margins! Could we simply subtract the margins from there ? How to get them ?

  ClipRect: TPdfBox;
  // see http://www.codeproject.com/Articles/1944/Guide-to-WIN-Regions
  if data^.iMode <> RGN_COPY then exit; // we are handling RGN_COPY (5) only..
  if not DC[nDC].ClipRgnNull then // if current clip then finish
    Canvas.fNewPath := False;
    DC[nDC].ClipRgnNull := True;
    fFillColor := -1;
  if Data^.cbRgnData > 0 then
    DC[nDC].ClipRgnNull := False;
    RGNs := @Data^.RgnData;
    for i := 0 to RGNs^.rdh.nCount - 1 do
      Move(RGNs^.Buffer[i * SizeOf(TRect)], RCT, SizeOf(RCT));
      ClipRect := Canvas.BoxI(RCT, false);

I believe that you briefly mentioned that automated PDF testing would be a great addition in order to avoid regressions with new code. Do you have any specific idea or requirements in mind (such as being compatible with both FPC and Delphi, being cross-platform, not using external tools...) ?

I thought about this a little and here is what I believe could work:
- Create a repository of trusted source to produce PDF documents for various features of SynPDF
- Use a tool such as ImageMagick to extract each of their pages as PNG images
- Automated tests compare the newly generated PNGs with source PNGs and fail if the difference is too big

Any thoughts ? Would you accept such a contribution ?

Named destination are useful in PDF documents as they act as bookmarks to access a specific part of the document (e.g. https://site.com/document.pdf#destination)
See: https://evermap.com/Tutorial_ABM_Destinations.asp

I see that SynPDF supports the TPdfDestination object which works fine from hyperlinks, but it looks like this doesn't create any entries in the Acrobat's "Destinations" pane. I suspect that it isn't supported ? Or perhaps I'm missing some kind of options to export them as named destinations ?

Or perhaps a similar open source tool already exists in the JavaScript / Go / .net... ecosystem?

After creating an encrypted (and only in that case) TPdfDocument, if the document's PDFA1 property is changed, an exception is raised when the PDF document is saved.

#21 Re: mORMot 1 » Server Side Validation » 2015-04-08 09:28:11

IMHO any kind of clients (REST included) must be put on a leash as there are plenty of bad things they could do which they shouldn't be allowed to. From the top of my head, I can think about:
- Access resources (rows/fields) without proper permission
- Delete/Update resources without proper permission
- Send invalid data which could result in either data corruption or server crash
- Send malformed (string instead of int, data is too long...) or missing data (required field) which could lead to future problems (data analysis, report generation...)

Where it should be done is another question which should be carefully thought out:
- Invalid access permissions should be checked (at the very least) before returning data to the client. If not before accessing data in the persistence storage
- Invalid modification access should be checked before modifying the persistence storage
- Invalid formated data or missing data should be checked before modifying the persistence storage
- Invalid data resulting in server crash should be handled as soon as it is received (e.g data flood, invalid characters, invalid requests...)
- Invalid data resulting in data corruption should be handled before writing to persistence storage

Regarding table access security, this is great but not enough for most systems: row-level and even field-level security and validation should be handled from the server.
I admit I do not know mORMot enough to say that it is not possible to do so or that it should handle everything.
But as far as I can tell mORMot includes both the data persistence access and REST server with direct interactions between them so it should provide a way to interfere and add safe guards between both.

I hope you'll see those remarks as constructive, not critics wink

I understand I should use TSQLAuthUser and TSQLAuthGroup to provide per-table restrictions.
However, how to handle more complex scenarios such as for example:

* A user who created a specific TBlogArticleRecord can have CRUD right access for it while other users can only have read access on that record ?
* A user can only receive a list of the TBlogArticleRecord he has the rights to read when calling for example TBlogArticleRecord.CreateAndFillPrepare as server will filter any un-authorized records ?

  if Assigned(aContext.Factory) then  //  <---- Factory is nil when called from the server

I'm using this as I need to access the Rest server from that method, to do a DB.BackupBackground.
How can this be handled ? Should I not rely on ServiceContext and use a global instance of my server instead ? This won't be great as this method is shared by both client and server.

Any help would be greatly appreciated.

BTW, did you try to define the method as such:

procedure JSContext.SetOptions(Value: TJSOptions);

(i.e. without the "const")

Unfortunately this still produces an exception in XE3.

I've tried multiple compilation options without any success. I've also tried disabling IDEFixPack without success.
The new code doesn't change anything either. And indeed, it looks like a wrong value is passer to the method.

So this is what I tried and it fixed the problem is:
- Make JSContext.SetOptions public
- In TSMEngine.Create call it instead of assigning to the property

Not sure how this can be explained.

Somebody REALLY need SM for XE3?

No but it's not reassuring that a specific Delphi version crashes wink
Anything we can do to try to debug this issue ?
Also, perhaps this should be prominently written somewhere to avoid people thinking either they got the wrong DLLs or the code is not working at all.

I can confirm the exception for JS_SetOptions on Delphi XE 3 sad

Thank you very much for taking the time to answer. I think accepting sponsored work through your company is a great idea and provides additional points for the mORMot project when used for commercial usages.

I'm currently evaluating various options for a future rewrite of a big project and I'm really impressed with the quantity of work and dedication Arnaud Bouchez put in the mORMot framework, documentation, web-site and associated projects. Congratulation!
That being said, choosing a framework for a project not only implies making sure it is technically good, but also that is will be supported and enhanced in the long run. Being open source is obviously a great start but this is not a guarantee that this will be updated in the future (See some great TurboPower projects which are hardly maintained anymore). So I wonder what is the business model around the mORMot framework: Is there some paid support or product covering the development costs, or a company sponsoring the work on the framework or... ? OR is it a pure gift to the Delphi community out of Arnaud Bouchez' own time ?
Also, would you consider sponsored work should we need a custom feature/fix/advanced support in the future ?

Thank you for your time and great framework. I will be back on those forums as I'll spend time evaluating the framework wink

Best regards.
