[PythonReports-users] Images

[Werner F. B. <wer...@fr...>]

Hi,

In my application the user can store images (e.g. wine labels, recipe 
preparation etc), the images are stored in the file system in a user 
defined folder and the application just stores the file name.

On my recipe report I like to show the image of the "Recipe finished" 
image if it exists.

I was hoping to use a function "getImagePath(THIS.id, 'imgtype') and it 
comes back with the appropriate full path to the image, in the case of 
the recipe report it would find the image showing the "finished" stage 
of the recipe.

Looking at the image element I don't see how I could do this, if it is 
possible could you give me some tips.

Werner

Sorry, at present there is no way to dynamically compute image file path 
or bitmap data.

That is quite a flaw in the template language.  I will have to think of 
a syntax for such things.  So far I've got several ideas, but all of 
them are either ugly or not backward compatible.

Best wishes,

Not the end of the world, but would definitely be very very nice if you 
can come up with something.

Is backward compatibility for something like this that important?

Could you create a "dynamic image" element which is ignored by older 
versions?

If you do something can you please allow the program to define what 
image type is used.

As a workaround, you could create a side-effect function that puts image 
files to a constant path, and then call this function via field or 
variable expression.  Set embed="true" in image element.

That is a terribly dirty hack, but for now it seems to be the only solution.

There are people that use PythonReports for many years and I do not want 
to break all their existing templates if I can avoid that.

I think I will do it like this:

For all body elements, box, and style elements all attributes will be 
allowed to contain an expression to evaluate in context of current data 
item.  If attribute value is an expression rather than constant, it must 
be prefixed with equal sign.  E.g.:

   <image file="=picture['file']" type="=picture['type']" />

For data elements, I will add attribute 'expr'; same as with fields, 
expression evaluation results will take precedence over literal data.

This change will surely slow down report building for existing templates.

Comments, anyone?

Best wishes,
alex.

I call that "forward compatibility", in other words templates created in 
previous versions will work on future version, but a template created in 
a newer version will not certainly work or will miss something when run 
on an older version.

Maybe restrict/reduce the change to just "image element" if expect to 
big slow down.

Hi Alex,

This time to the list.

Not sure, gave it a try but can't get it to work.


My getRecipeImage method returns a PIL.Image instance - what should it 
return?

It also looks like data.expr is NOT saved to the template file, i.e. if 
I save an reopen it the expression is not there.

Can you please give me a little pointer on how to use it.

When trying the above I see the following exception - probably because I 
don't use it correctly.

Hi Alex,

expr gets saved, I just didn't check _enable, but now I get the 
following exception, when I have the following for 'image':

     <image embed="false" type="png">
      <box height="30" width="75" x="405" y="35" />
      <data expr="ru.getRecipeImage(THIS.id)"></data>
     </image>

I keep digging through the doc etc, a pointer would obviously be very 
welcome.

Hhm, unless I still do something wrong - quit likely, here is what I get:

Changed things to:

     of type "Recipe finished" (fk_exttype_id=4), or an empty image

     """
     if recid:

         ds = app.ds
         imgF = app.getDirLocations()[5]
         with no_autoflush(ds):
             extfiler =  ds.query(db.Extfiler).filter_by(fk_recipe_id = 
recid,
fk_exttype_id = 4).first()
             if extfiler:
                 img =  Image.open(os.path.join(imgF, extfiler.filename))
             else:

Sorry, to confuse you, the file contains:

	<image type="png">
	       <box height="30" width="75" x="374" y="50" />
        	<data> expr="ru.getRecipeImagePNG(THIS.id)"</data>
	      </image>

When I run it through the debugger (WingIDE) I see at line 92 of fromdata in PILDrivers that the
param "data" contains:

u'expr="ru.getRecipeImagePNG(THIS.id)"'

As if the expression has never been evaluated (correct term), i.e. my getRecipeImagePNG method is never called.

Indeed it is not evaluated.  It shouldn't be, with your template 
contents.  Please change the <data> line to <data 
expr="ru.getRecipeImagePNG(THIS.id)" />

Explains why I like to use the designer.

I have this for my image:

     <image type="png">
      <box height="30" width="75" x="374" y="50" />
      <data expr="ru.getRecipeImagePNG(THIS.id)" />
     </image>

And I see this exception, not that my breakpoint in the 
getRecipeImagePNG is still never hit.

Matter of preference.  I find it much easier to understand in XML.

Could you try a fresh checkout?  I hope I have fixed this error.

I am lousy in remembering syntax.

My method is being called now - great, once per recipe, 3 for the test.

But then I get this exception:

Best regards and thanks for the quick turn around and the help on this.

Sorry, this one slipped through.  I have checked in a fix.

Hi Alex,

line 213 in wxPrint.drawImage needs to change to:
                 _data = prp.Data.get_data(_data)

line 92 in wxPrint.__init__:
         self.imgdata = dict([(_element.get("name"), 
prp.Data.get_data(_element))

and line 2363 in Builder.build_printout
                 prp.Data.make_element(_root, data=_image.getdata(),

I.e. in all change "Data" to "prp.Data"

If you prefer I can create you a patch later today.

At this point the image shows and the editor opens with out problems.

Thanks a lot for this, and PythonReports in general.
Werner
