DBRichViewEdit.BackgroundBitmap vs PNG

Post by mwilems1 »

With D2009 supporting several image formats including PNG, is there a way to save the background image of a DBRichViewEdit as something other than a bitmap?

My database sits over a TCPIP socket in a central location with both a windows client and a browser client. The Windows client has problems saving detailed images because of the amount of time it takes to transfer the binary data in bitmap form.

I currently load images using a TPicture and redraw them to a TBitmap.Canvas.Draw(). This makes a very large chunk of data. Some images can be extremely large such as x-rays and MRI images.

Is there some other way to store a background in RVE? I need to allow for text to be typed over the images.

In the current version of TRichView, document backgrounds can be only bitmaps.
You can consider placing text in table and using table/cell background image (they can be of any graphic type).
Or do not store/transfer background image in document, store it separately as PNG.

Thanks. That's what I suspected.

My users have the ability to create documents so to prevent confusion with my users, I will store backgrounds separately. This will also give me the ability to control size and aspect ratio to maintain the original proportions.

As future enhancements for background image,
1-the ability to store backgrounds in any format as in table backgrounds.
2-the ability to scale images and maintain height/width proportions so the image is not distorted.

Thanks again.
