The image in the target mail don't respect the height/width prop

mazluta · August 12

Hi,

i'm using TIdMessageBuilderHtml to build the message body from HTML,

the base HTML is Attach - myMail.html.

it's Base64 + some CSS - style="height:144px; width:120px;

when open this HTML with browser all look fine.

after sending this with the SMPT protocol the size of the image become the TRUE SIZE of the image.

and this is not what i want.

myMail.msg is the email as received in my outlook.

how can i fix it?

uSendSMTPMail.pas

myMail.html

MyMail.msg

Try to use width/height attrubutes instead of CSS.

mazluta · August 12

i tried but with no help.

it's look like outlook does what he want....

myTest-2.msg

What versions of Delphi and Indy are you using?

Did you compare the HTML that Outlook has to the HTML that you sent?

.msg files are binary files that Outlook creates for itself after converting the original data. It is not "received" from the sender. So, it is hard to diagnose them. Can you export an .eml file instead? Or at least view the source data for the .msg file? How does its HTML compare to the original HTML?

Not related to your problem, but why are you UTF-8 encoding the strings you give to Indy? Don't do that. Use plain strings instead, and let Indy encode them for you.

Also, you should not be messing with the TIdMessage properties after you have called TIdMessageBuilderHtml.FillMessage(). It has already set the properties accordingly for you.

Your HTML has conflicting charsets in its <meta> elements.

Also, it is unusual to use a "data:" url to display an image in an HTML email. Why are you not attaching the image file to the email and then using a "cid:" url to display it? Granted, TIdMessageBuilderHtml doesn't care what HTML you give it, but it is designed for "cid:" urls in mind.

Hi Remy

Thanks for your answers.

1. What versions of Delphi and Indy are you using?

delphi 10.3 + indy 10

2. Did you compare the HTML that Outlook has to the HTML that you sent?

yes they are the same.

3. the msg file was just to let those how answer to see what i get.

4. why are you UTF-8 encoding.

because of the Hebrew characters.

5. Your HTML has conflicting charsets in its <meta> elements.

what are the conflicts?

6. the 'body' is result of CkEditor. and i don't want to change there components.

and the <IMG> is most likely the Company logo.

maybe if i change the base64 to the size of the style - it will work.

Image attributes are not correct

h1XZgdBrJ2IOlrmq1SofeBwIdLyQHgGPgEfAIzCICNgIw6YHUZdhkvl//UZHbn5keAcAAAAASUVORK5CYII=";
height="144px"; width="120px"; /></div>

There should be no ; between attributes

Then the problem is not with Indy itself. It is entirely a problem with the email reader. It likely just doesn't support CSS, or doesn't handle it correctly.

3. the msg file was just to let those how answer to see what i get.

My point is, a .msg file is a binary file that is useless to people who don't use Outlook and can't open it (like me). Whereas an .eml file is plain text instead.

Quote

4. why are you UTF-8 encoding.

because of the Hebrew characters.

You are using a Unicode version of Delphi, and Indy handles Unicode strings for you. You don't need to encode the strings manually, nor is it beneficial to do so because you are assigning UTF8String's where UnicodeString's are expected, thus the Delphi compiler+RTL is simply going to implicitly decode your UTF-8 back to UTF-16 before Indy even sees the data. So just use plain Delphi strings, don't encode them manually. Indy defaults to UTF-8 in Unicode versions of Delphi when encoding the email data.

5. Your HTML has conflicting charsets in its <meta> elements.

what are the conflicts?

Look for yourself. You have a <meta charset> that states "utf-8", followed by a <meta http-equiv> that states "windows-1255".

6. the 'body' is result of CkEditor. and i don't want to change there components.

and the <IMG> is most likely the Company logo.

maybe if i change the base64 to the size of the style - it will work.

Doubtful.

The style attribute on the <img> element is formatted correctly:

<img src="data:image/png;base64,..." style="height:150px; width:125px" />

Multiple CSS styles in a single "style" attribute ARE supposed to be separated by semicolons.

Thanks for you detailed answers.

There are two attached messages. In MyMail there is style attribute but no width/height attributes. Outlook does not handle image size in style attribute correctly, it requires explicit width/height.

In MyTest2-2 there are width/height attributes but incorrectly separated by semicolon.

Thanks Alexander. i'm checking it all now.

Doubtful.

that work.

1. i remove the html conflict.

2. i gat the return string from the CkEditor.

3. i build simple HTML with 2 function.

one to iterate all image.

and for each <img> element i convert the base64 to be the same as the attribute (second function).

4. now, when i send the - "message" - its all look "normal"..

thank Remy and Alexander.

BTW - attach is the HTML file i build to convert the Images

mtTag_11197140.html

ok. now there is new problem.

Gmail want show message with image base on base64 string.

is there simple convert outlook message to Gmail Message?

mazluta · August 16

i see i can build the eMail for Gmail using IDMessage.

i can iterate in all base64 img convert them to png file but i dont see way to embedded the image it self into the html message back...

Outlook and Gmail use the same core SMTP and email standards. However, embedding images using "data:" urls may be common practice for web browsers, but it is not common practice for email.

According to:

https://stackoverflow.com/questions/6070196/what-is-data-uri-support-like-in-major-email-client-software

https://stackoverflow.com/questions/8580355/can-you-send-images-in-datauri-format-to-gmail

Gmail dropped support for "data:" urls over a decade ago.

I strongly suggest you stick to using "cid:" urls with file attachments in emails. All major html-aware email readers know how to handle "cid:" attachments. And TIdMessageBuilderHtml is designed with "cid:" in mind.

That is the same component you used to send an email to Outlook.

Because you don't embed it directly. You would need to instead attach the png file to the email, assign the attachment an ID in its "Content-ID" header, and then refer to that ID in a "cid:" url in the HTML <img> src. Have a look at the following articles on Indy's blog:

https://www.indyproject.org/2005/08/17/html-messages/

https://www.indyproject.org/2008/01/16/new-html-message-builder-class/

Your PNGs would be "related attachments" for the HTML, and can be attached using the TIdMessageBuilerHtml.HtmlFiles property, and identified with the TIdMessageBuilderAttachment.ContentID proeprty.

Wow, that is some really overcomplicated and inefficient code for such a simple task. That code can be greatly simplified. I'm not at a computer right now, otherwise I would whip up something smaller for you. Maybe I can later tonight or tomorrow...

Also, why are most of your "data:" media types prefixed with "image/image/" instead of just "image/"? That is just plain wrong, media types do not have such long hierarchies.

Also, TIdMessageBuilderHtml (and TIdMessage) supports attaching TStream objects, so you can avoid creating temp files on disk if you save your PNGs to memory instead.

Thanks Remy. no doubt your code is more efficient.
but on save the base64 as PNG is not the right way.
the base 64 is string depend on the file type.

i work with Envision https://www.intervalsoftware.com/envision.html
So i load any one of the type with appropriate object and convert it all to PNG, create the PNG, load it to the Html Files of the mail body and send the mail.

You are the MASTER.

Here is a hint: you can save a PNG to a TMemoryStream using TPngImage.SaveToStream(), and then attach it to the email using the TStream overload of the TIdMessageBuilderHtml.HtmlFiles.Add() method.

If you read the code I just gave you, it does exactly that. It is the same logic you posted earlier, I just reorganized and simplified it.

you right. sorry.

 PngGraphic := TPngGraphic.Create;
    try
      DibGraphic := TDibGraphic.Create;
      try
        Result := Base64ToImg(Base64Str, DibGraphic, FileExtn);
        if not Result then Exit;
        PngGraphic.Assign(DibGraphic);
      finally
        DibGraphic.Free;
      end;
      if PngGraphic.Empty then Exit;

did you read the TAO? it's old as the wheel of time......
