Oh, I see...you are using "free hand" drawing, not en ellipse.
In OnMouseDown event, actually in speHandMouseDown(Shift, X, Y) API,
nothing is drawn, because internally "free hand" drawing calculates
points on the Bresenham's line and so I need two points
X_from,Y_from -> X_to, Y_to.
Furthermore, not all points on the line (X_from,Y_from, X_to, Y_to) are taken into the account, because it depends on the step set (default is 2).
Actual drawing with "free hand" option is performed in OnMouseMove event
(speHandMouseMove(Shift, X, Y) API).
BTW, clear button in demo program does not work correctly, I must correct this.

ok, thanks... but to be useful in many cases I think OnMouseDown with "freehand" drawing should somehow draw.

Yes, you're right, it should draw a brush tip
at point (X,Y). I'll add an option for that in the next version,
something like DrawOnMouseDown := True/False; and then exclude
that point from line drawing in OnMouseMove event.
However, it will work only in slow rendering mode (because of filters).
While I was running demo program, I found a bug exactly in free hand drawing.
In on shape's MouseUp event it was written:
bool TGrapHand::MouseUp(TShiftState Shift, int X, int Y)
{
return TGrapBasic::MouseMove(Shift, X, Y);
// It should be MouseUp from the base class!!!
}
And that's the reason why clear button did not work correctly, actually free hand drawing in MouseUp event did not clear mask under the bounding rectangle.
I'll upload corrected dlls tomorrow.

Done.
http://www.sigmapi-design.com/archive/spEngine.zip
If RenderParams.DrawTipOnMouseDown := True; (as in new demo version) brush tip is drawn in onMouseDown (for free hand shape). It will work for all rendering modes.
I used a dirty trick and internally created a line (x,y -> x+1,y) and rendered only the first pixel.
Bug in speHandMouseUp API corrected. |

I made a little dll (32-bit only) that can load and execute 8bf plug-ins:
The same model as with drawing engine, but much simpler. Only ten functions
and one typedef. I even wrote a Delphi demo and unbelievable, it works...well, for most filters (some newer ones tend to crash badly).
Here is the zip file:

Have fun,

This demo is similar to the AllLayers Demo but adds Polyline custom Shapes and Loading and Saving to ImageEn Native file format (*ien) as well as Undo.
Standard image types such as JPEG and BMP, do not support layers, so to preserve layer information this demo supports the ImageEn Native Format (*.ien)
that loads and saves all layer information in the *.ien file.

@Spectric Thank you for the code to be able to load 8bf files. Really appreciate it. Will try to load some of my plugins to see on how they behave.

Raize DropMaster Demos
By Bill Miller Adirondack Software & Graphics
Full Source Demo Projects
Compiled with Delphi 10 Tokyo
Price: FREE
Requires ImageEn And Raize DropMaster Components
Raize Graphic Source
Raize Graphic Target
These demos show how to drag images from one application to another utilizing OLE drag and drop. VCL drag and drop does not allow drag drop between applications,
but OLE does. OLE drag and drop is usually implemented by delphi components. I know of three such components:
1. Melander DragAndDrop component- Open source http://melander.dk/delphi/dragdrop/
2. Raize Software DropMaster components- $99 https://raize.com/dropmaster/
3. LMD NG Drag&DropPack- $75 https://lmdinnovative.com/shopping
I recommend the Raize Software DropMaster component because it is easy to use,
works well with ImageEn and requires little source code to implement.
DropMaster is a set of components for adding inter-application drag-and-drop
support to Delphi and C++Builder applications for Microsoft Windows.
DropMaster supports dragging and dropping text-based data, graphics, and
custom formats. DropMaster comes with a collection of more than 40 sample
apps, which represent the results of extensive research into the drag and
drop behavior of many popular commercial applications.
I have used the Melander DragAndDrop component in older versions of Delphi but is several years old now and unfortunately, I have not been able to get it to compile in Delphi Tokyo.
These demos consist of two applications:
1. DropMaster Graphic Source Demo
2. DropMaster Graphic Target Demo
The Graphic Source Demo allows dragging an image from TImage and TImageEnView to OLE enabled drag and drop applications such as Microsoft Word, Microsoft Edge and the DropMaster Graphic Target Demo.

LMD NG DragAndDrop Demos
By Bill Miller Adirondack Software & Graphics
Full Source Demo Projects
Compiled with Delphi 10 Tokyo
Price: FREE
Requires ImageEn
LMD NG Drag&Drop is a part of Next Generation (NG) package suite. All these packages are based on new IDE and language features of latest Delphi IDE versions. NG Drag&Drop provides the ability to exchange data with other applications via standard Windows OLE drag&drop protocol.
These demos show how to drag images from one application to another utilizing OLE drag and drop. VCL drag and drop does not allow drag drop between applications, but OLE does. OLE drag and drop is usually implemented by delphi components. These demos utilize the LMD NG DragAndDrop components.
LMD NG Drag&DropPack- $75 https://lmdinnovative.com/shopping
LMD NG Drag&DropPack Trial- https://lmdinnovative.com/products/vcl/ngdragdrop/
LMD NG DragAndDrop
These demos consist of two applications:
NGDropTarget Demo which uses TNGDropSource to configure dragging data and initiate drag&drop operation (source side).
NGDropSource Demo which uses TNGDropTarget to receive dragging data by registering some application's control as a drop target and providing related events like OnDragEnter, OnDragOver, OnDragLeave, OnDrop; and a single OnDragAction event, which can be used instead of all previously mentioned events to simplify code.
