Loads a texture from memory, resource pack or disk file.
const char *filename,
DWORD size = 0,
bool bMipmap = false
- Texture file name.
- If this parameter isn't 0, it is the size of memory block containing the texture
in one of the known formats and the parameter filename is treated as a pointer to this block.
- If true, a set of mipmap levels is automatically created and used for rendering.
If successful, returns the texture handle.
Otherwise returns 0.
Supports BMP, DDS, DIB, JPG, PNG and TGA graphics file formats.
DDS format allows usage of DXT1-DXT5 texture compression which results in better performance
and lower video memory requirements.
Texture dimensions must be a power of 2. If this condition isn't met, the texture is
automatically padded to the closest power of 2 dimensions, bigger than it's actual size.
If filename specifies relative path, texture file is first searched within all resource packs attached with
Resource_AttachPack, then in the application disk folder.
If filename specifies absolute disk path, texture file is loaded directly from disk.
If mipmapping requested, a set of consequent smaller versions of the texture is generated and used for rendering.
This results in faster and higher quality rendering of sprites which are significantly reduced compared to their original size.
Textures with this option require 1/3 more video memory.
If the function fails, you may obtain error message with System_GetErrorMessage
function. Also if HGE_LOGFILE system state was set, the
error message is written to log.
When the texture isn't needed longer, you must delete it with
Import library: hge.lib
