Hello,

I want to notice that hpwImage support for neopaint's STW format is neopaint 4 only.

Details here:

You may use PNG instead.

Recompiled with updated Png-Library (Fix for hpwSimpleGraph)

hpwSimpleGraph now supports PNG format ?
Great news!

I am actively looking for a plugin capable of displaying .DDS (Direct Draw Surface) images files. Currently no plugin can do that. Do you know how to integrate this functionality into hpwImage ? Note that I do not want to convert and display, but just displaying image.dds in my NeoBook application.

Hello,

As Dec said in the other thread: Dds is not so popular so even GraphicEx does not support it.
So it has to be researched if some Delphi code is available and how much it would add to the plugin.
And is it worth to do this effort?

Regards

[UltraVox]

This is the only feature missing in my program : Displaying .DDS files !
Make a 3D software without DDS is like riding a bike without wheels

DDS files you do not seem popular, but without them, there would be no video game!

This is my dilemma.
I'll let you judge whether the effort is worth it ...

Hello,

I was asked how to draw freehand with hpwImage:

Make a new button on page 7 of the demo and paste the following code into it:

Code: Select all

hpwImageCreate "RGetAreaImage" "SetVar [#34][#91]DrawOnMove[#93][#34] [#34]0[#34]" " " "" "If [#34][#91]DrawOnMove[#93][#34] [#34]=[#34] [#34]1[#34][#13][#10] hpwImagePixels [#34]RGetAreaImage[#34] [#34]RGetAreaImage_MoveX[#34] [#34]RGetAreaImage_MoveY[#34] [#34]clRed[#34][#13][#10]Endif[#13][#10]" "SetVar [#34][#91]DrawOnMove[#93][#34] [#34]1[#34]" "" ""

Make another new button on page 7 of the demo and paste the following code into it:

Code: Select all

hpwImageCreate "RGetAreaImage" "SetVar [#34][#91]DrawOnMove[#93][#34] [#34]0[#34]" " " "" "If [#34][#91]DrawOnMove[#93][#34] [#34]=[#34] [#34]1[#34][#13][#10] hpwImageDrawLine [#34]RGetAreaImage[#34] [#34][#91]LastX[#93][#34] [#34][#91]LastY[#93][#34] [#34]RGetAreaImage_MoveX[#34] [#34]RGetAreaImage_MoveY[#34] [#34]clRed[#34] [#34][#34] [#34]psSolid[#34][#13][#10] SetVar [#34][#91]LastX[#93][#34] [#34]RGetAreaImage_MoveX[#34][#13][#10] SetVar [#34][#91]LastY[#93][#34] [#34]RGetAreaImage_MoveY[#34][#13][#10]Endif[#13][#10]" "SetVar [#34][#91]DrawOnMove[#93][#34] [#34]1[#34][#13][#10]SetVar [#34][#91]LastX[#93][#34] [#34]RGetAreaImage_LDownX[#34][#13][#10]SetVar [#34][#91]LastY[#93][#34] [#34]RGetAreaImage_LDownY[#34][#13][#10]" "" ""

The first uses hpwImagePixels and makes gap when moving fast.
The second uses hpwImageDrawLine and draw a series of lines.

Perfect Method 2 was great but first could be useful too.
Thanks you very much Hans, that's great.
Just need to study what you did.
