Recommendation : Self drawing TTF renderer

[rageworx]

Some years ago, I made TTF renderer for FLTK. And it makes better rednering result for any platforms.

• see here, https://github.com/rageworx/FLFTRender

You can own self TTF or OTF in resource, and load it then should render text on 3 or 4 depth Fl_RGB_Image. ( I didn't made it for gray image surface ) And there's True type renderer with this,

Dependencies : libfreetype2 Maybe it helps your YAIV for better looks...

Dear @fire-eggs , FLFTRender updated to supporting for 2 depth images, but recommend use like this ..

Render image information of fixed region box? widget ?

• Create an empty RGBA image with fl_imgtk. ( Fl_RGB_Image ) Also you can make it half-transparency by like this 0xRRGGBBAA -> half gray transparency 0x3333337F
• Render text to empty RGBA image.
• Set rendered image to invisible Fl_Box on Image viewing widget.

Render image information to text sized.

• Measure text box region with FLFTRender::MeasureText()
• Create empty image with box region ( also you can may transparency as you like )
• Render text to empty image
• Draw rendered image to anywhere.

Some famous image viewing program 'Honey view (꿀뷰)' in South Korea displays image infomation as like this: ( this picture is my embedded system, and took from smartphone, displays EXiF infromation or left side by TAB key )

You can make it invisible Fl_Box as overlay layer, and displays anything on Fl_Box with Fl_RGB_Image.

And HoneyView, it's freeware, and English version also availed - https://en.bandisoft.com/honeyview/

plus, some other case what I'm using for,

1. 
2. 

( analystic displays with fl_imgtk on Fl_RGB_Image )

Font hinting,

I was playing with using "secondary" windows to display additional info for images. But now I see your work here, I'm thinking an overlay approach could work really nice too!
