Image Box help.

[david1982]

Hello.

I am trying to use Image Box but I get "unknown type name 'GHandle'" when trying to build.

I assume that i have not enabled something in my ugfxconf file.

What could it be?

I have rom file system working with my image converted to a h file also .

Thank you.

Can you please paste the relevant code (Small test case that shows the error, without all the bloat). Please do also paste your gfxconf.h.

Well I have been playing around and I am now trying to get an image to display the normal way..

I am using the romfs and I have my romfs_files.h sorted with a bmp image converted via file2c (bf.h)

My code runs fine but no image displays (I toggle an LED in the while and the code does not jam up)

#include "gfx.h"
static gdispImage myImage;
int main(void) {
    halInit();
    chSysInit();
    coord_t			swidth, sheight;
    gfxInit();
    gdispSetOrientation(GDISP_ROTATE_90);
    swidth = gdispGetWidth();
    sheight = gdispGetHeight();
    gdispImageOpenGFile(&myImage, "bf.h");
    gdispImageDraw(&myImage, 20, 20, swidth, sheight, 10, 10);
    gdispImageClose(&myImage);
 while(TRUE) {
 gfxSleepMilliseconds(500);
 }
}

Start with the image demo and get that working first. Once that is working replace the image with your image. If it doesn't display then you have either not enabled the right decoder for your image or there is something funny about the image.

I hope that helps you find the problem.

Also, just looking at your gfxconf.h file, whilst you have enabled bmp images you have not enabled the particular sub-format of your image eg GDISP_NEED_IMAGE_BMP_8. As a first test set all the sub - image formats to TRUE in your gfxconf.h. You can always turn the extra ones off later to reduce code size.
