Hi Andrew,

What's wrong with

Rect1.New1(x-radius, y-radius, radius*2, radius*2)
DrawEllipse(Pen1.Value, Rect1.Value)

There is nothing wrong with that, I'm already using it.
For the circles on the forelayer I use Form.FCircle, and the wish was to have the equivalent function in the drawer.

At least the new FloodFill function would be of the biggest interest for me.

Thank you for your help and best regards.

Hi Andrew,

tsteward found an error with the DrawerEx when loading an image file with gif format, I get the same.

Code:

<font size="2"><font face="Courier New"><font size="2"><font face="Courier New">bmpImage.New1(</font></font></font></font><font face="Courier New"><font size="2"><font color="#0000ff"><font face="Courier New"><font size="2"><font color="#0000ff"><font face="Courier New"><font size="2"><font color="#0000ff">AppPath</font></font></font></font></font></font></font></font></font><font face="Courier New"><font size="2"><font face="Courier New"><font size="2">&</font></font></font></font><font face="Courier New"><font size="2"><font color="#800000"><font face="Courier New"><font size="2"><font color="#800000"><font face="Courier New"><font size="2"><font color="#800000">"\Rose.gif"</font></font></font></font></font></font></font></font></font><font face="Courier New"><font size="2"><font face="Courier New"><font size="2">)</font></font>
<font size="2"><font face="Courier New">drwImage.New2(bmpImage.Value)</font></font>
</font></font>

Is this a bug or a DrawerEx limitation ?

Thank you in advance and best regards.

Neither, it's a GDI+ limitation. You can't draw on a Bitmap derived from an image that uses a colour palette.

Thanks Andrew,

We will exclude the gif format for loading images.

Best regards.

Version 1.5 has the three improvements requested by Klaus in post #79

FloodFill.Flood overwrites everything until a specified boundary color is found.

DrawerEX.DrawCircle draws a circle - (now there's a surprise!)

DrawerEX.FillCircle draws a filled circle.

Hi Andrew, you are really great !

The new functions are already included in the Draw program.

Thank's for also having added the circle functions, so we find now in the Drawer also the Form's functions.

Thank you very much for your quick and valuable help.

Best regards.

It's probably a bug in Basic4ppc, post #16 onwards of this thread has the details http://www.basic4ppc.com/forum/quest...problem-2.html Erel should fix this in the next release. You can minimise the problem by Bitmap.Dispose then AddObject as in the code fragment in post#16 of the thread. You will still lose a small amount of memory for each time you New the same Bitmap object until the bug is fixed but it probably won't be noticable.

The bug exists for any library object that is reinitialised by Newing it more than once, it just shows up "best" on Bitmaps as they use a lot of memory.
