Sprite Not Showing Up...

[Rubberduckycooly]

I Have Created a Loader to load .gif images that is based off src_lib\loadbitmap.h but when i load a sprite using this method, nothing is displayed...

When i check the values the width, height, bit_depth and palette are all correct and assigned but the image still isn't showing up...

Here is My Code (I am using gif_lib (http://giflib.sourceforge.net) to get the data for the .gif images):

#include "..\src\GifLib\gif_lib.h"

static TLN_Bitmap LoadGIF(const char* filename)
{
	//Init
	TLN_Bitmap bitmap = NULL;
	GifFileType* Gif = DGifOpenFileName(filename, 0);
	DGifSlurp(Gif);

	//General Gif Values
	int width = Gif->Image.Width; std::cout << "Image Width = " << width << std::endl;
	int height = Gif->Image.Height; std::cout << "Image Height = " << height << std::endl;
	int bit_depth = Gif->SColorResolution; std::cout << "Colour = " << bit_depth << std::endl;

	bitmap = TLN_CreateBitmap(width, height, bit_depth);

	//Load ScanLines
	int pitch = TLN_GetBitmapPitch(bitmap);
	int l;

	for (l = 0; l<height; l++)
	{
		uint8_t* line = TLN_GetBitmapPtr(bitmap, 0, l);
	}

	//Colour Palette Values
	TLN_Palette pal;

	int palette_entries = Gif->SColorMap->ColorCount;
	int c;
	pal = TLN_CreatePalette(palette_entries);
	std::cout << palette_entries << std::endl;
	for (c = 0; c < palette_entries; c++)
	{
		TLN_SetPaletteColor(pal, c, Gif->SColorMap->Colors[c].Red, Gif->SColorMap->Colors[c].Green, Gif->SColorMap->Colors[c].Blue);
	}
	TLN_SetBitmapPalette(bitmap, pal);

	/* bitmap loaded */
	if (bitmap)
	{
		/* accept only 8 bpp */
		int bpp = TLN_GetBitmapDepth(bitmap);
		if (bpp == 8)
			TLN_SetLastError(TLN_ERR_OK);
		else
		{
			TLN_DeleteBitmap(bitmap);
			bitmap = NULL;
		}
	}

	if (!bitmap)
		TLN_SetLastError(TLN_ERR_WRONG_FORMAT);

	return bitmap;
}

I haven't tried the sample but the code seems correct.
BUT: what you're loading is a TLN_Bitmap and then you complain about sprites not showing up. I think there's a confusion here. To show sprites, you need a TLN_Spriteset object. A spriteset contains a bitmap and other information. I'm afraid you're mismatching resource types. Could you post the code that calls and uses your LoadGIF function? I guess the error is there.

This Bit of code load the sprite sheet:

TLN_Bitmap b = PSDK::SpriteSheet::LoadGIF(DFM->GetItemFromData("data/Sonic1.gif").c_str());
TLN_SpriteData* sd = new TLN_SpriteData(); sd->x = sd->y = 1; sd->w = 28; sd->h = 40;
TLN_Spriteset spriteset = TLN_CreateSpriteset(b, sd, 1);
//TLN_SetSpritePalette(0, pal->Palettes[pal->curPalette]);
TLN_SetSpriteSet(0, spriteset);
TLN_ConfigSprite(0, spriteset, TLN_TileFlags::FLAG_NONE);
TLN_SetSpritePicture(0, 0);
TLN_SetSpritePicture(0, 0);
TLN_SetSpritePosition(0, 50, 50);

and this bit is the full class that handles it:
class SpriteSheet
{
public:
SpriteSheet(const char* path)
{
spriteSheet = LoadGIF(path);
palette = TLN_GetBitmapPalette(spriteSheet);
}
~SpriteSheet() {}

static TLN_Bitmap LoadGIF(const char* filename)
{
	//Init
	TLN_Bitmap bitmap = NULL;
	GifFileType* Gif = DGifOpenFileName(filename, 0);
	DGifSlurp(Gif);
	FILE* img;

	/* open file */
	img = fopen(filename, "r");
	if (!img)
		return NULL;

	//General Gif Values
	int width = Gif->Image.Width; std::cout << "Image Width = " << width << std::endl;
	int height = Gif->Image.Height; std::cout << "Image Height = " << height << std::endl;
	int bit_depth = Gif->SColorResolution; std::cout << "Colour = " << bit_depth << std::endl;

	bitmap = TLN_CreateBitmap(width, height, bit_depth);

	//Load ScanLines
	int pitch = TLN_GetBitmapPitch(bitmap);
	int l;
	std::vector<int> Lines;
	GifPixelType* gifline = new GifPixelType(); 

	for (l = 0; l < height; l++)
	{
		//Lines.push_back(DGifGetLine(Gif, gifline, width));
		uint8_t* line = TLN_GetBitmapPtr(bitmap, 0, height - l - 1);
		fread(line, pitch, 1, img);
		std::cout << l << std::endl;
	}

	//Colour Palette Values
	TLN_Palette pal;

	int palette_entries = Gif->SColorMap->ColorCount;
	int c;
	pal = TLN_CreatePalette(palette_entries);
	std::cout << palette_entries << std::endl;
	for (c = 0; c < palette_entries; c++)
	{
		TLN_SetPaletteColor(pal, c, Gif->SColorMap->Colors[c].Red, Gif->SColorMap->Colors[c].Green, Gif->SColorMap->Colors[c].Blue);
		std::cout << "R = " << (int)Gif->SColorMap->Colors[c].Red << " G = " << (int)Gif->SColorMap->Colors[c].Green << " B = " << (int)Gif->SColorMap->Colors[c].Blue << std::endl;
	}
	TLN_SetBitmapPalette(bitmap, pal);

	/* bitmap loaded */
	if (bitmap)
	{
		/* accept only 8 bpp */
		int bpp = TLN_GetBitmapDepth(bitmap);
		if (bpp == 8)
			TLN_SetLastError(TLN_ERR_OK);
		else
		{
			TLN_DeleteBitmap(bitmap);
			bitmap = NULL;
		}
	}

	if (!bitmap)
		TLN_SetLastError(TLN_ERR_WRONG_FORMAT);

	return bitmap;
}

TLN_Bitmap spriteSheet;
TLN_Palette palette;

Hope that is what you wanted/needed! @megamarc
