There are verbs in the jqtide locale for reading and writing images. NB. reading file images to argb matrix img=. readimg_jqtide_ 'foo.jpg'
NB. reading file images from memory to argb matrix img=. getimg_jqtide_ 'foo.jpg' NB. write image data to file NB. x rgb matrix NB. y filename [ ; 'jpeg|png|ico|bmp' [ ; 'quality' ; [0,100]|_1 img writeimg_jqtide_ 'foo.png' However I guess these verbs cannot be used in jconsole. Neither can J8 load or use gtk stuff. Вт, 06 авг 2013, Dan Farmer писал(а): > Hello, > > New J user here (well I've been dabbling for a few months, but getting > more serious now).
