Description
When using bitmaps of certain sizes, the oled.bitmap
function will not draw the bitmap correctly.
See the below example bitmap:
/*
SQ_Symbol [8, 9]
12345678
.--------.
0x01|********|
0x02|* *|
0x04|* *|
0x08|* *|
0x10|* *|
0x20|* *|
0x40|* *|
0x80|* *|
0x01|********|
'--------'
*/
const int SQ_Symbol_Height = 9;
const int SQ_Symbol_Width = 8;
const uint8_t SQ_Symbol[] = {0xFF, 0x01, 0x01, 0x01, 0x01, 0x01, 0x01, 0xFF,
0x01,0x01,0x01,0x01,0x01,0x01,0x01,0x01};
Calling oled.bitmap
with a 0
for the y0
argument draws the bitmap as expected:
oled.bitmap(0, 0, (uint8_t *)SQ_Symbol, SQ_Symbol_Width, SQ_Symbol_Height);
output:
********
* *
* *
* *
* *
* *
* *
* *
********
However, if I pass a non-zero value for y0
, the bitmap does not draw correctly:
oled.bitmap(0, 1, (uint8_t *)SQ_Symbol, SQ_Symbol_Width, SQ_Symbol_Height);
output:
********
* *
* *
* *
* *
* *
* *
* *
The bottom row is not drawn. This also occurs for bitmaps that have heights of 10, 11, 12, etc.
