Font smoothing?
« Thread started on: Jul 15th, 2015, 1:22pm » |
|
When I print text into a graphics box the text is displayed with smoothing under Vista and Win8 (if the user has this feature enabled under the desktop settings).
Is there a way I can print text into a graphics box without the smoothing and without the user having to change their desktop settings?

If by "smoothing" you mean antialiasing one way would be to create the font using the Windows API, which gives you full control (you could for example adapt code for printing text on a slope). But why would you want to reduce the text quality?

Well I have to print the text into the graphics box at 8pt size and at this size the AA makes the characters look ugly and indistinct. I really need them to be nice and crisp like standard 8pt texts.
The setting that needs to be changed is under Windows Color & Appearance > Open Classic Appearance Properties > Effects > Use Following Method to Smooth Edges > (Clear or Standard). I need it set to Standard.

Here's a direct comparison (Arial, 8pt):
I actually prefer the antialiased version; I wouldn't call it "ugly and indistinct", but YMMV.

Perhaps the ugliness is more to do with the SIZE parameter since this has an influence over resolution. What pixel width is your drawing and what SIZE parameter are you using to print the image?

I didn't realise the OP was doing any (hardcopy) printing; his only reference was to "printing text into a graphics box". If indeed output to a printer is involved then that puts a quite different complexion on the issue.

Well I am using 8pt Lucida Console which has characters 7*11 pixels in size. Here is what they look like on the screen and when magnified 2x. Yes I am printing it too.

Got the antialiased and non-antialiased the wrong way round but you see what I mean. Look at the "W" for example. Not sure how I insert images into these posts.

Was that created using LBB v3.00? What puzzles me is that several of the letters (including the W) appear to have been clipped, which is one reason why they look so ugly. But LBB is not supposed to clip characters printed to a graphics window.
Here is what I get with 8pt Lucida Console at 96 DPI (magnified 2x):
The characters are not clipped in this case.

The word "clipped" got me thinking. Yes, I expect they are clipped, because I am drawing them with a 7 pixel spacing (as they should be) but the antialiasing seems to overlap from one character to the next, so when I print the following character it clips the previous one. I expect I can change the print options to merge with what is already there.
Anyway, for reasons to long to explain, I need the characters without antialiasing and ideally without the user needing to change their windows settings. Is there no easy way?
I suppose I could create a copy of the standard character set and copy each character into position using the drawbmp command?
Your characters still look different to mine. I'm using the statement:
print #main.gfx, "font Lucida_Console 0 11"
I need the characters to be 7x11
Yes I am using version 3.0

Ah, you said you were drawing 8pt text so that's what I specified in my program.

So why don't you explicitly specify a width of 7 pixels rather than allowing Windows to choose the width (which may be 7 pixels, but there's no guarantee):
Code:print #main.gfx, "font Lucida_Console 7 11"

Well, as I said, the most straightforward way is to call the CreateFont API directly - I would class that as relatively easy, and it's the method I used to create the bitmap I uploaded. Here's my program, adapted to force the cell width and height; if it doesn't give identical results to yours now I'm mystified:
Code: open "Test" for graphics as #w
#w "font Lucida_Console 7 11"
#w "\\Hello World! (antialiased)"
calldll #gdi32, "CreateFontA", 11 as long, 7 as long, _
0 as long, 0 as long, 400 as long, 0 as long, 0 as long, _
0 as long, 0 as long, 0 as long, 0 as long, _
_NONANTIALIASED_QUALITY as long, 0 as long, _
"Lucida Console" as ptr, hf as ulong
hw = hwnd(#w)
calldll #user32, "GetDC", hw as ulong, hdc as ulong
calldll #gdi32, "SelectObject", hdc as ulong, hf as ulong, _
oldhf as ulong
calldll #gdi32, "DeleteObject", oldhf as ulong, ret as long
#w "\Hello World! (non-antialiased)"
#w "getbmp bitmap 0 0 210 24"
bmpsave "bitmap", "C:\temp\lbbaa.bmp"
wait

I would like to make a donation Richard for all the help you have given me and all your efforts with LBB. Does that $6.99 at the bottom go to you?

No, that goes directly to Conforums, this forum's host.

Something to be aware of if you care about LB 4.04 compatibility: my program works but seemingly only once; thereafter the 'native' font selection seems to be broken. Perhaps it's necessary to select the original font back before exit; I don't know (and TBH I don't really care, since it works fine in LBB as is).
