The transparency feature with diagram images

When you save a diagram as image with DiagTransfer you can save it with the background wholly transparent so the background color or the texture web page will show through. You can see an example of transparency with this image saved with DiagTransfer with the "Transparent window Mode" and "Coordinates" options selected.

It's very easy to make web pages as this one, you only have to save a diagram with DiagTransfer and load a texture file for the background in your web page.

If you like the texture I have created for this page, you can save it, for this right-click on the page and select "Save Picture As" or "Save Image As".

NOTE: To get fine diagrams as these displayed in this page, you should (if not) enable font smoothing in Windows's"Display utility". more...

Tip:
You can save diagrams with pieces with the color you want.
For this you must choose "Semi-transparent mode",
change "Pieces color" and set the level of DiagTransfer's
"Windows transparency" to 100% "Opaque" in "File/Preferences".

If you design a web page with diagrams made with DiagTransfer, send me a link, I'll paste it on my page..

Anti-aliasing:

Because the background color of the image is mixed in with the foreground colors, simply replacing a background color with another is not enough to simulate transparency. If the web page background color differs (too much) of the DiagTransfer windows background color when you save a diagram image you get something as you can see with this picture. The effect in this case is a lot of grey dots, because the original image was anti-aliased to a white background color.

To correct this you must change the color of the Diagtransfer window (approximately the same color), then the image will be anti-aliased with the web page background color.

You have not to set the same color, if the color is almost the same this work well.

Cut of a web page with a solid green background color.and a diagram saved with a transparent background but the DiagTransfer background window was white.

The same page but the Diagram was saved after the DiagTransfer background windows color has been set to a color almost the same as the web page background color

 

With this method, you cannot create diagrams like this one because the background color changes from red to green. This diagram was created by exporting it in RTF mode without its frame, and pasted in a frame in LibreOffice and creating a gradient for the background of this frame. dégradé
