icon.library 46.4 test versions

[PeterK]

Hi AGS,
its a feature of my library (and you may like it or not) that it replaces all planar icon images which are smaller than 8x8 pixels with my standard 8x8 dot image, because I don't like tiny icons (hardly to see and to click on). So please make your images at least 8x8 pixels in size.

Why do you use the "darken" function for generating the second image when the first image has only black and no other color. Black cannot be made darker ! Why do you use the OS 3.5 colormapping for such an icon instead of using a planar image with one bitplane?

[AGS]

No you misunderstood me. My icons are displayed, but shifted. I don't know which functions and features I use as I generated the symbols with the standard icon editor and that is not very informative. Further I don't know much about icons.

[PeterK]

No I didn't misunderstood you.

Update:
But you didn't tell me yet anything about how you tried to create these icons.
My assumption was, that you used the OS 3.9 IconEdit, but it seems to be impossible to get a problem like yours with this tool. If the images in the OS 3.9 IconEdit are not at the right position then you can move the images by clicking on the arrow gadgets in the tools area.

So, how did you do it ?

[AGS]

I created the icons with the os 3.9 icon editor. I use icons as symbols for my gadgets in my GUI.

I saved the attached Icons as you said and they are greater than 8x8 pixels. I use DrawIconStateA(). With your lib they are drawn shifted one pixel to the right and one pixel to the bottom. May be my mistake somehow but I just want to find it out.

[PeterK]

I guess that you are using a gfx-card and thus the direct drawing mode. Right?
If so, then please try to switch to an AGA screenmode just to see if the images are shifted there too.

[AGS]

w/o the card they are not shifted.

[PeterK]

Strange !

I've just tested your icons with WinUAE and P96 in truecolor and hicolor, but there are no shifts. What is your gfx-card and is it a CGX-driver ??

When you select the drawer icon is there a shifting by one pixel depending on whether you press the left mouse button or not ? Pressing it down switches into the dragging mode which can be used as the correct reference position.

[AGS]

My 'gfxcard' is E-UAE with P96 and truecolor. The test w/o gfxcard was E-UAE booted w/o startup-sequence. Pressing the mouse above my icons has no shifting effect. They are just drawn shifted when I call DrawIconStateA().

[AGS]

These are the Tags I use:

.tags		dc.l	ICONDRAWA_EraseBackground,0
		dc.l	ICONDRAWA_Frameless,1
		dc.l	ICONDRAWA_Borderless,1
		dc.l	TAG_END

[PeterK]

Try this please:
Ok removed, I hope you got it.

[AGS]

Sorry, I cannot decrunch rar here. Please send zip or lha.

How to detect E-UAE ?

[AGS]

Ok, now the icons are not shifted anymore.

Btw, I noticed that os4/png icons are not antialiased at their edges.

[PeterK]

Yes, I know that the OS4 icons try to hide their awful edges sometimes by using the alpha blending. Maybe, I will do the same what I make with the PNG icons, using two levels of merging with gray before it gets transparent. But I don't support alpha blending or truecolors.

But do you know how to detect E-UAE easily ?

[AGS]

I do not know that.

[PeterK]

Ok, I will create another shell command to switch these pixel shifts on or off.

[AGS]

I guess it has to do something with the tags borderless/frameless or such. Borders are typically one pixel.

[AGS]

I just tested your previous version that showed the shifting with WinUAE and found that the shifting happens there also.

[PeterK]

Hmm, all available details about your Amiga screenmode (size, depth, modeid) and your WinUAE version, gfx-card settings, screenmode etc please. WinUAElog.txt, WinUAEbootlog.txt and config please.

[AGS]

The WinUAE is from 2011. But I tried it with a new FS-UAE and it was the same, the shifts are there. I was not able to find any logfiles, however logging was turned on. I guess the problem is, how I draw the icons:

.tags		dc.l	ICONDRAWA_EraseBackground,FALSE
		dc.l	ICONDRAWA_Frameless,TRUE
		dc.l	ICONDRAWA_Borderless,TRUE
		dc.l	TAG_END

I supply no DrawInfo within the tags to DrawIconStateA() and a2 set to zero (sub.l a2,a2).
