Images
6 years ago
This tutorial will attempt to explain how Images are working for the Gamebuino META.
General Idea
The general Idea of images is to have one standard way of drawing graphics onto the screen, on the lights, or on other images.
An image can have multiple different resources (such as, SD card BMP file, flash array, or ram array). An Image can also have either the color mode RGB565 or be indexed.
On an Image itself you can draw lines, shape, text, and more importantly: other images! The gb.display itself is an image, meaning you can do all those actions with gb.display
Now, let's just pretend we'd already have an image...
#include <Gamebuino-Meta.h>
Image myImg; // let's just pretend this was a correctly initialized image (which it is not)
void setup() {
gb.begin();
}
void loop() {
while(!gb.update());
gb.display.clear();
// now we can draw the image to the display, at x=10 and y=0
gb.display.drawImage(10, 0, myImg);
}
As you can see, drawing an image is pretty straight-forward.
Image Sources
As already mentioned, there are different kind of image sources, which result in different constructors for the Image object.
RAM Image
Image( uint16_t width , uint16_t height [, ColorMode col = (RGB565|Index) ] , [ uint16_t frames = 1 [, uint8_t fl = 1 ]])
A RAM image is simply an image with a blank buffer in RAM. They are only two parameters needed to initialize it: the width and the height. Both are of type uint16_t.
The optional other parameters are explained below.
For example, gb.display is such a RAM image, and is, by default, initialized with Image(80, 64)
Flash Image
Now, if you want to save some assets, like sprites, in your game, you typically don't want to have them in RAM, so, you can save Images in Flash, too!
You don't have to code the images yourself, use the Image to code converter !
They are either a uint8_t array, or a uint16_t array. The first one is recommended to use for an indexed image, the second one for an rgb565 image. In the indexed case there is two pixels per byte. In the rgb565 case one pixel per two bytes, so one pixel per array entry.
Both have a header, which are slightly different:
For uint8_t data
<width>, <height>, <frames-lower-8-bit>, <frames-upper-8-bit>, <frame_loop>, <transparent_color>, <color_mode>,
For uint16_t data:
<width>, <height>, <frames>, <frame_loop>, <transparent_color>, <color_mode>,
For an rgb565 image the color mode is 0, for an indexed image it is 1.
The transparent color is which color should be interpreted as transparent. In rgb565 mode 0 is interpreted as no transparency, in indexed mode anything greater than 0x0F is interpreted as no transparency. This means that, instead of like 0xAA as transparent color you should just use 0x0A, else it won't work.
Frames and Frame Loop are explained below.
So, for an indexed checkered-board you'd do
#include <Gamebuino-Meta.h>
const uint8_t myImgBuf[] = {
8, 8, // width, heigth
1, 0, // frames
0, // frame loop
0xFF, // transparent color
1, // color mode
0x07, 0x07, 0x07, 0x07,
0x70, 0x70, 0x70, 0x70,
0x07, 0x07, 0x07, 0x07,
0x70, 0x70, 0x70, 0x70,
0x07, 0x07, 0x07, 0x07,
0x70, 0x70, 0x70, 0x70,
0x07, 0x07, 0x07, 0x07,
0x70, 0x70, 0x70, 0x70,
};
Image myImg(myImgBuf);
void setup() {
gb.begin();
}
void loop() {
while(!gb.update());
gb.display.clear(RED);
// draw the image
gb.display.drawImage(10, 10, myImg);
}
Or for a small RGB565 image you'd do
#include <Gamebuino-Meta.h>
const uint16_t myImgBuf[] = {
2, 2, // width, height
1, // frames
0, // frame loop
0, // transparent color
0, // color mode
0x1234, 0x2345,
0x3456, 0x4567,
};
Image myImg(myImgBuf);
void setup() {
gb.begin();
}
void loop() {
while(!gb.update());
gb.display.clear();
// draw the image
gb.display.drawImage(10, 10, myImg);
}SD Card Image
Lastly, you can also load assets right from the SD card, from BMP files! Please keep in mind that every SD-card image has to keep track of an internal RAM buffer, and thus your RAM can fill up quickly if using too many at once.
Supported are BMP files with 4-bit, 24-bit and 32-bit bitdepth.
4-bit-depth BMPs are converted to indexed images, according how the current palette of the gamebuino meta is. If exact matches aren't present, closest matches are being used.
24-bit-depth BMPs are converted to rgb565 images.
32-bit-depth BMPs are also converted to rgb565 images. The alpha channel is partly ignored: If a pixel is more than 50% transparent it will appear as a transparent pixel in the final image, else as a solid pixel.
You can create a BMP image like this:
Image myImg("PATH/TO/IMAGE.BMP");
It will automatically detect what kind of BMP is present and adapt accordingly
Image Animations
Now that we discussed different image sources, let's talk about some other features these images have: Animations!
The idea is basically that you have, in your flash/RAM buffer, just multiple frames stacked. Or, with BMP image, have frames stacked vertically.
As explained above, you have different ways to specify the number of frames you have.
Frame Loop hereby is the animation speed, we'll just use 1 for now.
#include <Gamebuino-Meta.h>
const uint8_t myAnimBuf[] = {
8, 8, // width, height
0x2A, 0x00, // let's just say the animation has 42 frames
1, // frame loop
0xFF, // no transparency
1, // indexed image
/* all the frames go here */
};
Image myAnim(myAnimBuf);
void setup() {
gb.begin();
}
void loop() {
while(!gb.update());
gb.display.clear();
// let's just draw the image
gb.display.drawImage(0, 0, myAnim);
}
Aaaaand, there you go, it automatically progresses to the next frame and loops the animation! As simple as that!
Now, let's say the animation is a tad to fast to you, and you only want to progress one animation frame every two gamebuino frames...that is what the fl (Frame Loop) parameter is there for! In the buffer you just set a different Frame Loop parameter, e.g. a value of 2 would only progress the animation every two frames.
Example
Let's say you have this image (scaled up x4 for this tutorial for easier visibility):
As you can see, that will be a four-frame animation, we will be picking that pink background as transparent background. Using this tool we can convert our image to code (setting Number of frames to 4):

Image PlayerIdling(PlayerIdlingData);

gb.begin();
}
void loop() {

gb.display.clear(LIGHTBLUE);
gb.display.drawImage(5, 5, PlayerIdling);
}
If that animation is too fast you can simply change the frame loop in the converter to something greater than 1, or manually adjust the fourth parameter in the header of the image data.
Spritesheet & Tilemapper
Now, we can also use one image as an entire spritesheet, and thus make a tilemapper! The idea exactly the same as with animations: when setting fl (Frame Loop) parameter to zero the animation doesn't automatically progress anymore. So, creating a spritesheet would look like this:
const uint8_t spritesheetBuf[] = {
8, 8,
0x2A, 0x00, // if we have 42 sprites
0, // no frame looping
0xFF,
1,
/* all the sprites */
};
Image spritesheet(spritesheetBuf);
And, with setFrame() we can set the current frame, so if we have our tilemap in an array called tilemap we could do something like this to render it all:
for (uint8_t y = 0; y < height; y++) {
for (uint8_t x = 0; x < width; x++) {
spritesheet.setFrame(tilemap[y*width + x]);
gb.display.drawImage(x*8, y*8, spritesheet);
}
}
Please note, while that does work with BMP spritesheets, that setFrame is slow with BMP images, and thus it is recommended to use a flash array.
Image Cropping
You can also directly crop an image while drawing it, for that you just need to specify the x, y, width and height of the cropped image. Example, assuming that myImage is an image:
gb.display.drawImage(0, 0, myImage, 4, 4, 8, 8);
Indexed Images
The default color Index is defined by the following table:
| Index | Hex | name |
|---|---|---|
| 0 | 0x00 | black |
| 1 | 0x01 | dark blue |
| 2 | 0x02 | purple |
| 3 | 0x03 | green |
| 4 | 0x04 | brown |
| 5 | 0x05 | dark gray |
| 6 | 0x06 | gray |
| 7 | 0x07 | white |
| 8 | 0x08 | red |
| 9 | 0x09 | orange |
| 10 | 0x0A | yellow |
| 11 | 0x0B | light green |
| 12 | 0x0C | light blue |
| 13 | 0x0D | blue |
| 14 | 0x0E | pink |
| 15 | 0x0E | beige |
You can change the palette by making your own array of the Color[] type. To do that, you use gb.display.setPalette:
// this is obviously a pretty trashy palette, but enough to show how things are working
Color myPalette[16] = {
(Color)0x0000,
(Color)0x0001,
(Color)0x0002,
(Color)0x0003,
(Color)0x0004,
(Color)0x0005,
(Color)0x0006,
(Color)0x0007,
(Color)0x0008,
(Color)0x0009,
(Color)0x000A,
(Color)0x000B,
(Color)0x000C,
(Color)0x000D,
(Color)0x000E,
(Color)0x000F,
};
// set the palette
gb.display.setPalette(myPalette);
// if the palette is in RAM you can, after setting, just modify one of the entries
myPalette[5] = (Color)0xFFFF;
// draw stuff
// reset back to default palette (only if you want to)
gb.display.setPalette(Gamebuino_Meta::defaultColorPalette);
Now, the question is, when is the color palette been used? The answer is: when drawing an indexed image to an rgb565 image, or when sending an indexed image to the screen.
This means, if your gb.display buffer is rgb565 (which is default), you could just switch the palette between drawing sprites and you will have a more-than-16-color image to draw on the screen.
This does, however, mean that if gb.display is an indexed image, while drawing sprites the color index is completely ignored, the indexes are just directly mapped onto each other. You can still swap the palette before sending to the screen, though. With cycling colors you can achieve some old-school tricks like the flowing water effects.

Well, if you don't use any of the extra features i'd dare to say it isn't really more complex (except of index vs rgb565, which is a burden of color graphics).
NEW 6 years ago
Hello, since I have my gamebuino, I am working in a little test program (like testing all the general features) as a first gamebuino app before attempting to port Tuxemon (or at least creating a Pokemon like game reusing their sprites), as for now, all seems to work well but loading images on using the image to code converter doesn't work the colors doesn't match.
the image is a simple png image and i have tested with it's 16 color bmp counterpart and some of the gray appears reddish. (now it works, I have to force-load the game by quitting before or it doesn't load from the SD card but from the internal memory)
Do we have to load bmp files in a certain way or it is just that mspaint is a piece of crap for doing simple color images for the Gamebuino?
and for the SD card image loading app, is the loading done with absolute path convention?
if my game is in the testgame directory (Sd rootdirectory/testgame) and my file is screen.bmp, to load the image to write "screen.bmp" or "testgame/screen.bmp"
I have checked the example and at lest Displaystatic is broken, it uses an older version of your framework (where you indicate color mode and number of frames) here is the quickfix for this example, replace similar lines by these:

the image is a simple png image and i have tested with it's 16 color bmp counterpart and some of the gray appears reddish.
This may be due to the BMP being RGB888 (24-bit color depth) but the gamebuino converts to RGB565 (16-bit color depth). It might also be just because of how the screen works, I am not entirely sure what you mean. Do you load the BMP directly or do you use the online conversion tool? I assumed now that you used RGB565 mode rather than indexed mode.
Do we have to load bmp files in a certain way or it is just that mspaint is a piece of crap for doing simple color images for the Gamebuino?
You should be able to just create BMPs in paint or whatever program you want to
and for the SD card image loading app, is the loading done with absolute path convention?
Every SD paths are relative to the sketch folder, so you would just load "screen.bmp" while it actually lies in "/testgame/screen.bmp". This is to prevent files of different games from colliding with each other.
EDIT: Also, please use a code block for code. That paragraph symbol in the editor bar, and then there is a button to make a code block

@Ddrmax You might be interested in our test program then, I just open-sourced it ;)

corrected my post
The problem with loading was because of my first atempt with indexed and because when you reboot the gameduino (without quiting the game) it loads the game from memory other than loading it from the SDcard
tested the loading from SDCard but i think i will go by using only image to code converted images, the ram usage changes significantly SD: 7603 Free ->same image via image to code 16473 Free

Glad you figured it out!

That is because when loading from SD it needs to buffer the image in RAM, while, if it is in flash, well, it is already in addressable space

since i' hadn't really codded for the arduino zero and TFT, is it possible to gain more space by addressing sprites and images by using PROGMEM?
I have done a simple test by adding progmem and it seems to work but i don't know if using it could deteriorate more the flash than only loading the code of the game

the META uses a SAMD MCU, which uses an ARM processor, instead of an AVR one, which most of the other arduinos use.
What does this mean for you? PROGMEM is obsolete, the keyword does nothing. By defining something as const it will land already in flash and you can just access it normally, no need to pgm_read_byte or thelike.
EDIT: that question would have probably been better for a separate topic, since it has nothing to do with images, just so you know for the future ;)

Is this why there is only one memory percentage showed when we compile a Gamebuino Meta game, instead of two different percentages in Arduboy? When I made an ebook on Arduboy, I had to use F() to memorise my text with enough space. So, are PROGMEM and F() useless with the Meta?

I was trying to use a tilesheet but there doesn't actually seem to be a matching function prototype for specifying the part of the image to draw like it shows in the tutorial above:
gb.display.drawImage(0, 0, myImage, 4, 4, 8, 8);
Or another thing that would be nice is to be able to specify the WxH of the tiles in an image header instead of just the number of tiles that way multi-row images will work.

The version you DL via the arduino board manager probably doesn't have that yet, it is in the git repo, though
Or another thing that would be nice is to be able to specify the WxH of the tiles in an image header instead of just the number of tiles that way multi-row images will work.
The advantage of having a large, stacked, image is that, for each frame, you can just propagate the buffer by increasing without jumping more to render the entire frame. If you have multiple rows, you'd lose that advantage. You are free to use intermediate tools that then convert your spritesheets or thelike to such a stacked image.

What is the release schedule like? Just got my tracking # yesterday so I'll be ready for it soon :)
