Hi all, I'm having trouble loading a 16x16 monochrome image such that it can be used as a cursor%.
The documentation states that using load-file with a kind of 'bmp always loads as colour, but it would be nice to have a new kind (perhaps 'monochrome-bmp) that loads monochrome images to monochrome bitmaps. The documentation also states that a monochrome png will load as a monochrome bitmap%, but it seems to always load as colour (changing the bit depth from 1 to 32 during the load-file, regardless of the value specified for kind). Perhaps there's something wrong with my image file (attached) but gimp and Windows both show a 1-bit colour depth. I have a work-around, in that converting the image to xbm seems to work. But I'm still interested to know what I was doing wrong, anyone have any ideas? Cheers, Kieron. **** #lang racket (require racket/gui) (define bm (make-object bitmap% 16 16 #t #f)) (printf " ~a ~a ~a ~a~n" (send bm get-width) (send bm get-height) (send bm get-depth) (send bm is-color?)) (send bm load-file "test-icon.png" 'png #f #t) ;(send bm load-file "test-icon.xbm" 'xbm #f #t) (printf " ~a ~a ~a ~a~n" (send bm get-width) (send bm get-height) (send bm get-depth) (send bm is-color?)) (define cursor (make-object cursor% bm bm 0 0))
