Nice basketweave window background

[NoCforMe]

Working on my icon editor (another project that'll probably never get finished), I wanted a patterned background for the editing window so one could see the extent of the image being edited. I came up with a pretty handsome looking pattern if I don't say so myself.

Pretty simple: create a small bitmap from data in the program, use it to create a pattern brush, then just fill the window using the brush with FillRect() before displaying the image. The pattern is 2 bytes wide by 16 bytes high (16x16, 256 bits total), and it forms a tiled pattern that fills the window seamlessly.

I worked the pattern out on graph paper before coding it. It's got a few little bobbles in it, which actually make it look more ... organic. (All those NOTs are due to coding the bits that are dark, which was easier because there are fewer of them, then reversing them.)
Update: Fixed the bobbles. Now the pattern is perfect.

Looks good.

There is also a PatBlt function worth looking at as well (https://learn.microsoft.com/en-us/windows/win32/api/wingdi/nf-wingdi-patblt)

Nice 
I am very interested in part where you import bmp and export to tiny compressed . Ico format

Not sure if you're replying to me or Fearless. If it's me, I didn't import anything; I created a bitmap on graph paper, then just encoded the bits as bytes in my .data section (shown in code above). Was that your question?

You meantioned icon editor,so i expressed interested in file menu,about proc export compressed. ico file when finished editing icon

[NoCforMe]

Oh, that. I'm a looooong way away from that; still getting basic functionality working, like cropping images, etc. Lotsa work.

Regarding writing icon files, no, I'm not planning on even thinking about compression here. I don't anticipate ever working with icons large enough to require saving space.

Otherwise, writing icons is pretty easy. They're actually the same as cursor (.cur) files with the exception of one field in the file header, which I already know how to generate.
