Graphics > Usenti conversion of devkitpro example picture

#109703 - Aeonitis - Mon Nov 20, 2006 2:58 pm

I was trying to understand the process of converting images (especially 256 color bitmaps) and i thought i could start on replacing actual pictures located in the NDS Examples tutorial available with devkitpro...

to be more detailed it is the BG_ROTATION demo available in your default folder at "C:\devkitPro\Projects\Tryouts\nds\Graphics\2D\BG_Rotation" and i am trying to re-compile it after i have replaced the images ".bin"s and palettes with my own picture but it ends up similarly fuzzy to these pictures:-

This is another person's pictures but they are the same thing that happen to me.... (YES I DO REALISE THAT's GBA, not Nds but that's not the point)

but it's supposed to look like

please help me, and thank you for your time in reading this!

Have you tried converting the image in tiled (not linear) mode? Which command line are you using to convert the image, or which GUI program with which options?

GUI: Usenti version 1.7.6
Original picture file: drunkenlogo.bmp (which is any picture i renamed to be used in this case), 24 color Bitmap.

Options as shown below (pretty much the default options):-

pal (checked) - start=0, num=256
image (checked) - tiles(checked), bpp=8,cprs=none
Map(unchecked)
Tile Group - sqr,1,cstm(unchecked)
Area - as img (checked)
File - ...\Desktop\drunkenlogo.bin, type=Binary(*.bin), h file(checked), u16

So these options are displayed before i export them:-
pal: 0-256 [256]
img: tile, 8bpp, cprs: none
area: (0,0)-(308,276) [308, 276]
meta: 1x1 tiles (8x8 px)
map: -
files: drunkenlogo.h drunkenlogo.gbfs

even though the actual files exported (as i have seen) are
drunkenlogo.h, drunkenlogo.img.bin, drunkenlogo.pal.bin

and i rename the last 2 of these three files to fit the example in the "data" folder before i "make". i.e. to the names
drunkenlogo.bin & palette.bin

I am sorry i do not have a webspace to show the options on a picture but i will arrange one soon, appreciating your help tepples :)

The BG_Rotation example uses a bitmap, not a tilemap, so switch the image-mode to bitmap. Also, 308x276 doesn't fit the DS screen; you need to resize the image beforehand, export only a portion of the image, or take care of the discrepancy on the NDS side of things.

Thank you Cearn, sorry for the late reply but it has worked, thanks guys...
