other cases however according to this embodiment the output from the resolution memory 203 in the image area is reversed therefore it is simply necessary to always set the text drawing portion to 34 1 34 regardless of whether the position is inside outside the image region according to the fifth to the seventh embodiments the resolution memory is constituted in such a manner that each pixel is composed of 1 bit the present invention is not limited to this however and a structure may be employed which is arranged in such a manner that the gradation data is selected by four types of gradation memories by composing each pixel by 2 bit as described above the image processing apparatus according to the present invention is capable of forming an image of a mixture of texts and images while possessing excellent image quality by necessitating reduced memory capacity fig1 is a block diagram which illustrates the structure of an eighth embodiment of the image processing apparatus according to the present invention referring to fig1 reference numeral 301 represents an input terminal 302 represents a data discriminating circuit 303 represents a resolution memory 304 and 305 represent gradation memories 306 represents an image memory 307 represents a priority encoder 308 and 309 represent selectors and 310 represents an output terminal the host computer is connected to the input terminal 301 so that data to be stored is supplied from the host computer to the resolution memory 303 the gradation memories 304 and 305 and the image memory 306 the data discriminating circuit 302 interprets command information added to the stored data before data.
